Damless all-season hydroelectric power plant

A damless all-weather hydroelectric power station (BVHES) is proposed, which is designed to generate electricity without building a dam through the use of gravity flow energy.

Due to the manufacture of various standard sizes for different flow rates, as well as cascade installation, BVGES units can be used both in small farms and for industrial power generation, especially in places remote from power lines.

Structurally, the HPP rotor is installed vertically, the rotor height is from 0.25 to 2.5 m ... The structure is fixed on rivers with ice formation at the bottom of the channel, and in an open (non-freezing channel) __ on a fixed catamaran.

The power of the installation is proportional to the area of ​​the blade and the speed of the flow in the cube. The dependence of the power received on the shaft of the BVHPP on its size and flow velocity, as well as the estimated cost of the hydroelectric unit, is presented in the following table:

BVHES power, kW depending on the flow rate and unit size

The payback period of the installation does not exceed 1 year. The BVGES prototype was tested on a full-scale water test site.

Currently, there is technical documentation for the production of industrial designs according to customer specifications.

Mini hydroelectric power station. micro hydro power plants

A small hydroelectric power plant or small hydroelectric power station (SHPP) is a hydroelectric power plant that generates a relatively small amount of electricity and consists of hydropower plants with an installed capacity of 1 to 3000 kW.

micro hydro power plant is designed to convert the hydraulic energy of the fluid flow into electrical energy for further transfer of the generated electricity to the power system.

The term micro means that this hydroelectric power plant is installed on small water bodies - small rivers or even streams, technological channels or elevations of water treatment systems, and the power of the hydroelectric unit does not exceed 10 kW.

SHPPs are divided into two classes: these are micro-hydro power plants (up to 200 kW) and mini-hydro power plants (up to 3000 kW). The former are used mainly in households and small businesses, the latter in larger facilities.

For the owner of a country house or a small business, the former are obviously of more interest.

Based on the principle of operation, micro-hydro power plants are divided into the following types:

Water wheel. This is a wheel with blades, installed perpendicular to the surface of the water and half immersed in it. During operation, water presses on the blades and causes the wheel to rotate.

In terms of ease of fabrication and obtaining maximum efficiency at minimum cost, this design works well.

Therefore, it is often used in practice.

Garland mini hydroelectric power station. It is a cable thrown from one side of the river to the other with rotors rigidly fixed on it. The water flow rotates the rotors, and from them the rotation is transmitted to the cable, one end of which is connected to the bearing, and the other to the generator shaft.

Disadvantages of a daisy-chain hydroelectric power station: high material consumption, danger to others (long underwater cable, rotors hidden in the water, blocking the river), low efficiency.

Rotor Daria.

This is a vertical rotor that rotates due to the pressure difference on its blades. The pressure difference is created due to the fluid flow around complex surfaces. The effect is similar to the lift of a hydrofoil or the lift of an airplane wing. In fact, SHPPs of this design are identical to the wind turbines of the same name, but are located in a liquid medium.

The Darrieus rotor is difficult to manufacture, at the beginning of work it needs to be untwisted.

But it is attractive in that the rotor axis is located vertically and the power take-off can be made above the water, without additional gears. Such a rotor will rotate with any change in flow direction. Like its air counterpart, the efficiency of the Darya rotor is inferior to the efficiency of a propeller-type SHPP.

Propeller.

This is an underwater “windmill” with a vertical rotor, which, unlike an air one, has blades of a minimum width of only 2 cm. This width provides minimum resistance and maximum rotation speed and was chosen for the most common flow rate - 0.8-2 meters per second.

Propeller SHPPs, as well as wheeled ones, are easy to manufacture and have a relatively high efficiency, their frequent use is due to this.

Classification Mini HPP

Power generation classification (applications).

The power generated by a micro hydro power plant is determined by a combination of two factors, the first is the pressure of the water entering the blades of the hydro turbine, which drives the generator that generates electricity, and the second factor is the flow rate, i.e.

volume of water passing through the turbine in 1 second. Consumption is the determining factor in assigning a hydroelectric power plant to a particular type.

According to the generated power, SHPPs are divided into:

• Household power up to 15 kW: used to provide electricity to private households and farms.
• Commercial up to 180kW: power small businesses.
• Industrial with a capacity of over 180 kW: they generate electricity for sale, or the energy is transferred to production.

Design classification

Classification by installation site

• High-pressure - more than 60 m;
• Medium pressure - from 25 m;
• Low-pressure - from 3 to 25 m.

This classification implies that the power plant operates at different speeds, and a number of measures are taken to mechanically stabilize it, because.

the flow rate depends on the pressure.

Components of a mini hydroelectric power station

The power generating plant of a small hydropower plant consists of a turbine, a generator and an automatic control system. Some elements of the system are similar for solar generation or wind generation systems. The main elements of the system:

• hydroturbine with blades connected by a shaft to a generator
• Generator.

  Mini hydroelectric power station (HPP) for home

  Designed to generate alternating current. Attached to the turbine shaft. The parameters of the generated current can be relatively unstable, but nothing like power surges occurs during wind generation;

• Hydro turbine control unit provides start and stop of the hydraulic unit, automatic synchronization of the generator when connected to the power system, control of the operating modes of the hydraulic unit, emergency stop.
• Ballast Load Block, designed to dissipate currently unused power by the consumer, avoids the failure of the power generator and the monitoring and control system.
• Charge controller / stabilizer: designed to control the charge of batteries, control the rotation of the blades and voltage conversion.
• Bank AKB: storage capacity, the size of which determines the duration of autonomous operation of the object fed by it.
• inverter, many hydro generating systems use inverter systems. In the presence of a battery bank and a charge controller, hydraulic systems are not much different from other systems using renewable energy sources.

Mini hydroelectric power station for a private house

The increase in electricity tariffs and the lack of sufficient capacity make relevant questions about the use of free renewable energy in households.

Compared to other renewable energy sources, mini hydropower plants are of interest, since with equal power with a windmill and a solar battery, they are able to produce much more energy in an equal period of time.

A natural limitation on their use is the lack of a river

If a small river, a stream flows near your house, or there are elevation differences on lake spillways, then you have all the conditions for installing a mini hydroelectric power station. The money spent on its purchase will quickly pay off - you will be provided with cheap electricity at any time of the year, regardless of weather conditions and other external factors.

The main indicator that indicates the efficiency of the use of SHPPs is the flow rate of the reservoir.

If the speed is less than 1 m / s, then it is necessary to take additional measures to accelerate it, for example, make a bypass channel of variable cross section or organize an artificial height difference.

Advantages and disadvantages of microhydropower

The advantages of a mini hydro for a home include:

• Environmental safety (with reservations for fish-fry) of the equipment and the absence of the need to flood large areas with enormous material damage;
• Ecological cleanliness of the energy received.

  There is no effect on the properties and quality of water. Reservoirs can be used both for fishery activities and as sources of water supply for the population;

• The low cost of the generated electricity, which is several times cheaper than that generated at thermal power plants;
• Simplicity and reliability of the equipment used, and the possibility of its operation in stand-alone mode (both as part of and outside the power supply network).

  The electric current generated by them meets the requirements of GOST in terms of frequency and voltage;

• The full service life of the station is at least 40 years (at least 5 years before overhaul);
• inexhaustibility of the resources used to generate energy.

The main disadvantage of micro-hydro is the relative danger to the inhabitants of the aquatic fauna, because. rotating turbine blades, especially in high-speed currents, can pose a threat to fish or fry.

It is designed to absorb the excess active power of micro-hydro power plants. BNN is a cabinet with thermoelectric heaters inside.

The automatic control device is designed to control and protect the drive. It provides excitation of the asynchronous generator and automatic control of the produced voltage and frequency.

UAR provides overload, overvoltage and short circuit protection

The water supply device is made in the form of a network box, inside which there is a water supply hose with a closing body.

The water supply device is designed in such a way that floating residues do not enter the drive.

Full, mounting and connecting dimensions are shown in Figure 1.

installation requirements

For the operation of a micro power plant, the presence of pressure (difference in water levels) is a prerequisite (see Figure 2).

Full screen hydroelectric dam

The head can be obtained due to the difference in watermarks between:

- two rivers

- lake and river;

— on the same river, due to the flattening of the curve.

Pressure is also possible during the construction of a dam.

Figure 2 shows the micro HP setup according to the barrier design diagram. To create pressure on the turbine along the river, which has many slopes and rapids, an outlet pipeline has been installed.

A small rock dam dissipates to increase the pressure.

The piping must provide water for the installation with minimal head loss.

The length of the pipeline is determined by local conditions.

Before the power supply, the inlet and main valves required to start and stop the micro HPW must be installed in the pipeline.

Small cogeneration plants (overview)

Cogeneration plants for individual houses — micro CHP,« Micro-CHP (microCHP)" is an abbreviation for " heat and power combined” (combination of heat and electricity) is an installation designed for heating individual housing) is one of the most interesting areas in the development of heating technology.

Micro CHP(microCHP) has already found thousands of users and will be included in the manufacturers' directories in the coming years.

Various technical solutions are implemented in the manufactured and designed designs - from the traditional internal combustion engine (Otto engine), to steam turbines and piston engines, as well as the Stirling external combustion engine. When promoting this equipment, manufacturers give arguments of both an economic and environmental nature: a high (over 90%) total Efficiency micro-CHP reduces the cost of energy supply and the amount of harmful emissions, in particular carbon dioxide, into the atmosphere.

Company Senertec GmbH, part of Wahi Group, which has implemented about one and a half ten thousand installations to date Dachs(Badger) with an internal combustion engine.

Electric power - from 5 kW, thermal - from 12.5 to 20.5. Senertec offers an energy center for an individual home, and when using several modules and a large commercial facility. In addition to the compact cogeneration module, it includes as standard a buffer tank with a capacity of up to 1000 liters with a heat substation mounted on it, which combines all the piping elements necessary for heating and hot water.

Additionally, there is also an external condensing heat exchanger. Various models of Dachs units operate on natural, liquefied gas, diesel fuel.

There is a Dachs RS model designed to run on biodiesel from rapeseed oil. The estimated cost of the gas model is 25,000 euros.

Micro CHP (Mini-BHKW) ecopower German company Pover Plus Technologies(included in Vaillant Group) is already on sale in the European market.

Its electric power is modulated in the range from 1.3 to 4.7, thermal - in the range from 4.0 to 12.5 kW. The total efficiency of the installation exceeds 90%, it is fueled by natural or liquefied gas.

The estimated cost of the model is 20 thousand euros.

At the end of last year, the company Otag Vertribes a pilot batch of a floor-standing gas micro CHP plant was produced lion ®-Powerblock electric power 0.2-2.2, thermal - 2.5-16.0 kW.

It applied steam two-cylinder engine with a double free-moving piston: steam alternately enters either the left or the right cylinder, setting the working piston in motion.

The steam generator of the device consists of a pressurized burner and a steel coil; steam temperature - 350 ° C, pressure - 25-30 bar. Its condensation is carried out directly in the device.

As expected, lion ® on pellets will be available April 2010.

Company Microgen(Great Britain), one of the leaders in production mini-CHP, first developed Stirling's engine so small that it can be built into the boiler of an autonomous heating system.

company Wahi Heating UK announced its intention to bring to the UK market in 2008 a compact (wall-mounted) micro-CHP with an electric power of 1, thermal - up to 36 kW. The unit was developed jointly with Microgen Energy and is a combination of its compact single-piston Stirling engine with a Bahi condensing boiler.

The model is equipped with two burners: the first one is a pressurized modulating burner that ensures the operation of an electric generator and the production of 15 kW of thermal power, the second one satisfies the object's additional need for heat. The prototype of the installation was presented at the exhibition ISH-2007.

Microgen, in collaboration with the Dutch natural gas supplier Gausine and De Dietrich Remeha Group producing boilers Remeha, develops a complete solution for heating and electricity production.

De Dietrich-Remeha Group plans to produce and sell wall mounted condensing boiler with integrated Stirling engine. It has already been exhibited at the ISH-2007, 2009 exhibitions. The boiler will be produced in one- and two-circuit versions. Some technical characteristics of the boiler: Its heat output will be 23 kW, in the second case - 28 kW; electric power - 1 kW; heat output Stirling – 4.8 kW, efficiency at 40/30°C - more than 107%, low CO2 and NOx emissions, noise level - less than 43 dB(A) per 1 m.

Dimensions: 900x420x450 mm.

The most important advantage of the HRE boiler is that part of its high efficiency up to 107% (thanks to the condensing technology) is used to generate electricity. The cost of electricity, as well as emissions of harmful substances, are reduced by 65% ​​compared to thermal power plants using traditional fuel.

For an average dwelling, the "Remeha-HRE" boiler produces 2500 - 3000 kW per year, which is 75% of the average consumption, thus saving about 400 euros per year. During heating and electricity production, emissions of harmful substances are reduced by 20%. 8 boilers are being tested in Holland. At the moment, another 120 boilers are being launched for larger testing. Commercial production is scheduled to begin in 2010.

Over 30,000 homeowners have installed micro-CHP in Japan Honda with quiet, efficient internal combustion engines housed in a sleek metal housing.

To main

Small hydroelectric power plants are usually divided into two types: "mini" - provide a unit of power up to 5000 kW, and "micro" - in the range from 3 to 100 kW. The use of hydroelectric power plants of such capacities is not new for Russia, but it is a well-forgotten old one: in the 50s and 60s, thousands of small hydroelectric power plants operated.

Currently, their number almost does not reach hundreds of pieces. Meanwhile, the constant increase in prices for fossil fuels leads to a significant increase in the cost of electricity, the share of which in production costs is 20% or more. In this regard, a small hydroelectric power plant received a new life.

Modern hydropower, compared to other traditional types of electricity, is the most efficient and environmentally friendly way to generate electricity.

The small hydroelectric plant continues in this direction. Small power plants make it possible to preserve the natural landscape, the environment, not only during the operation phase, but also during the construction process.

Mini hydro power plant 10-15-30-50 kW

In the future, it does not have a negative impact on water quality: it completely retains its original natural properties.

In canned fish rivers, water can be used for aquatic plant species. Unlike other environmentally friendly renewable energy sources such as solar, wind, small hydroelectric power plants are practically independent of weather conditions and can provide a stable supply of electricity to economical consumers. Another advantage of small energy is savings.

At a time when natural energy sources - oil, coal and gas - are depleted, constant growth is more expensive, the use of cheap, affordable renewable energy sources, especially small ones, makes it possible to produce cheap electricity. In addition, the construction of small HPP facilities is cheap and quickly pays off. Thus, the construction of a small HPP with an installed capacity of about 500 kW, the cost of construction work is about 14.5-15.0 million rubles.

In the combined table, design documentation, equipment construction, construction and installation of small hydroelectric power plants are put into operation for 15-18 months. The high frequency of electricity from HPPs is no more than 0.45-0.5 rubles per 1 kWh, 1. This is five times lower than the cost of electricity actually sold by the power system.

By the way, in the next year or two years, the electric power systems are going to increase by 2-2.2 times, so the construction costs will be repaid in 3.5-5 years. The implementation of such a project in terms of the environment will not harm the environment.

In addition, it should be noted that the reconstruction, previously deducted from the operation of a small hydroelectric power plant, will cost 1.5-2 times cheaper.

Many Russian scientific and industrial organizations and companies are engaged in the design and development of equipment for such HPPs.

One of the largest is the intersectoral scientific and technical association INSET (St. Petersburg). INSET specialists have developed and patented original technical solutions for automated control systems for small and micro hydropower plants. The use of such systems does not require the constant presence of maintenance personnel at the facility - the hydraulic unit operates reliably in automatic mode. The control system can be implemented on the basis of a programmable controller, which allows you to visually control the parameters of the hydraulic unit on the computer screen.

Hydraulic installations for small and micro hydro power plants produce MNTO "built-in", designed to operate in a wide range of flows and pressures with high energy properties and made with propeller, radial and axial turbine blades.

The scope of delivery usually includes a turbine, generator and automatic control of the hydraulic unit. The flow rates of all turbines are based on a mathematical modeling method.

Small energy is the most effective solution to energy problems for areas belonging to areas of decentralized power supply, which is more than 70% of the territory of Russia. Providing energy for remote regions and energy shortages are costly.

And here it is far from useful to use the capabilities of the existing federal energy system. The economic potential in Russia is much higher than the potential of renewable energy sources such as wind, solar energy and biomass combined. In the national energy program, the INSET company is developing "The concept of development and facilities, the layout of small hydroelectric power plants in the Republic of Tyva", according to which this year will put into operation a small hydroelectric power station in the village of Kyzyl-Khaya.

Currently, INSET hydroelectric power plants operate in Russia (Kabardino-Balkaria, Bashkortostan), the Commonwealth of Independent States (Belarus, Georgia), as well as in Latvia and other countries.

Environmentally friendly and economical mini-energy has long attracted the attention of foreigners.

Micro INESET operates in Japan, South Korea, Brazil, Guatemala, Sweden, Poland.

Free electricity - do-it-yourself mini hydroelectric power station

If a river or even a small stream flows near your home, then with the help of a home-made mini hydroelectric power station you can get free electricity. It may not be a very big budget replenishment, but the realization that you have your own electricity costs much more.

Well, if, for example, in a country house, there is no central power supply, then even small power capacities will be simply necessary. And so, to create a home-made hydroelectric power station, at least two conditions are necessary - the presence of a water resource and desire.

If both are present, then the first thing to do is to measure the flow rate of the river.

It is very simple to do this - throw a twig into the river and measure the time during which it swims 10 meters. By dividing meters by seconds, you get the speed of the current in m/s. If the speed is less than 1 m / s, then a productive mini hydroelectric power station will not work.

In this case, you can try to increase the flow rate by artificially narrowing the channel or by making a small dam if you are dealing with a small stream.

As a guide, you can use the ratio between the flow velocity in m/s and the power of the electricity removed from the propeller shaft in kW (propeller diameter 1 meter).

These are experimental data, in reality the received power depends on many factors, but it is suitable for evaluation. So:

• 0.5 m/s - 0.03 kW,
• 0.7 m/s - 0.07 kW,
• 1 m/s - 0.14 kW,
• 1.5 m/s - 0.31 kW,
• 2 m/s - 0.55 kW,
• 2.5 m/s - 0.86 kW,
• 3 m/s -1.24 kW,
• 4 m/s - 2.2 kW, etc.

The power of a homemade mini hydroelectric power station is proportional to the cube of the flow rate.

As already mentioned, if the flow rate is insufficient, try to artificially increase it, if this is of course possible.

Types of mini hydroelectric power plants

There are several basic options for homemade mini hydroelectric power plants.


This is a wheel with blades mounted perpendicular to the surface of the water.

The wheel is less than half immersed in the stream. Water presses on the blades and rotates the wheel. There are also turbine wheels with special blades optimized for the liquid jet. But these are rather complex designs, rather factory-made than home-made.

It is a vertical axis rotor used to generate electrical energy.

A vertical rotor that rotates due to the pressure difference on its blades. The pressure difference is created due to the fluid flow around complex surfaces. The effect is similar to the lift of a hydrofoil or the lift of an airplane wing. This design was patented by Georges Jean-Marie Darier, a French aeronautical engineer, in 1931. It is also often used in the construction of wind turbines.

garland a hydroelectric power station consists of light turbines - hydro vingrotors, strung and rigidly fixed in the form of a garland on a cable thrown across the river.

One end of the cable is fixed in the support bearing, the other end rotates the generator rotor.

Mini hydroelectric power station - Leneva hydropower unit

The cable in this case plays the role of a kind of shaft, the rotational movement of which is transmitted to the generator. The flow of water rotates the rotors, the rotors rotate the cable.

Also borrowed from the designs of wind farms, such a "underwater windmill" with a vertical rotor. Unlike an air propeller, an underwater propeller has blades of a minimum width. For water, a blade width of only 2 cm is sufficient. With this width, there will be a minimum resistance and a maximum rotation speed.

This width of the blades was chosen for a flow velocity of 0.8-2 meters per second. At high speeds, other sizes may be optimal. The propeller does not move due to water pressure, but due to the occurrence of lift. Just like an airplane wing. The propeller blades move across the flow rather than being carried along by the flow in the direction of the flow.

Advantages and disadvantages of various homemade mini hydroelectric systems

The disadvantages of a stringed hydroelectric power station are obvious: high material consumption, danger to others (a long underwater cable, rotors hidden in the water, river blocking), low efficiency.

Garland HPP is a kind of small dam. It is advisable to use in deserted, remote places with appropriate warning signs.

You may need permission from the authorities and environmentalists. The second option is a small stream in your garden.

Rotor Daria - difficult to calculate and manufacture.

At the beginning of work, it needs to be untwisted. But it is attractive in that the rotor axis is located vertically and the power take-off can be made above the water, without additional gears. Such a rotor will rotate with any change in the direction of flow - this is a plus.

The most widespread in the construction of home-made hydroelectric power plants were propeller and water wheel schemes.

Since these options are relatively easy to manufacture, require minimal calculations and are implemented at minimal cost, have high efficiency, are easy to set up and operate.

An example of the simplest mini-hydroelectric power station

The simplest hydroelectric power station can be quickly built from an ordinary bicycle with a dynamometer for a bicycle headlight.

Several blades (2-3) must be prepared from galvanized iron or not thick sheet aluminum. The blades should be 2-4 cm long from the wheel rim to the hub, and 2-4 cm wide.

These blades are installed between the spokes in any improvised way or pre-prepared fixtures.

If you are using two blades, then set them opposite each other.

If you want to add more blades, then divide the circumference of the wheel by the number of blades and install them at regular intervals. You can experiment with the depth of immersion of a wheel with blades in water. Usually it is immersed from one third to half.

The option of a camping wind farm was considered earlier.

Such a micro hydroelectric power station does not take up much space and will serve cyclists well - the main thing is the presence of a stream or river - which is usually the case at the campsite.

A mini hydropower plant from a bicycle will be able to light a tent and charge cell phones or other gadgets.

- not only fresh forest air, but also a lot of problems. Communications laid decades ago often cannot cope with the influx of people who want to settle in the bosom of nature. Either preventive maintenance, or an accident, or a new neighbor leaves the entire block without electricity for several hours. And somewhere there are no such benefits: the power line has not yet been laid, the gas pipeline is far away, and the local water utility is in no hurry to embrace new horizons. It is time to think about housing that will not depend on central communications, where there is its own gas, electricity, and water supply. That is to build. Is it possible? And in general, how to make country life as independent as possible from external factors?

You give energy!

The main issue is electricity. All communications depend on it to one degree or another.

Some cottage owners solve the issue of energy supply by purchasing a generator. Since this will be the only source of energy supply for the house, you need to take the choice seriously. It must be reliable, safe, consume the optimal amount of fuel and, of course, produce a minimum of noise.

The main two types of generators are gasoline and diesel. The duration of continuous operation of the gas generator is no more than 12 hours, the power is a maximum of 15 kVA (13.5 kW). Usually they are kept in cottages "just in case" and run only if the electricity is turned off.

A diesel generator is suitable for constant power supply of the house. It is more powerful than gasoline and has a longer service life. The diesel unit is fireproof. Of course, it is impossible to call it absolutely silent, but it buzzes noticeably quieter than its gasoline counterpart. The main plus of a diesel mini-power plant (as generators are also called) is the ability to save on electricity. Diesel fuel is relatively inexpensive, at least cheaper than gasoline. The diesel generator requires minimal maintenance and has a service life of more than 20 years. So for owners of suburban housing, a diesel power plant is a solution to the problem.

You can go even further in the issue of power supply to the cottage - install a mini-CHP. Thermal power plants are turbine, gas piston and mini-turbine. The former are used to provide energy to large industrial enterprises and entire microdistricts.

For home energy production, the last two options are suitable. Such mini-CHPs take up little space. The structure is about two meters long and about 1.5 meters wide and high. Install it in the utility room or next to the cottage, under a canopy. The system is monitored by a computer, so there is no need to hire a special operator. Mini-CHP can be equipped with gas leakage sensors, fire and security systems. This makes them extremely safe. The service life of a mini-CHP is 25-30 years.

What are the advantages of own CHP compared to public networks?

Firstly, independence from the operation of the central power plant.

Secondly, in addition to its direct "duty" - to generate electricity, a mini-CHP will also provide the cottage with hot water. The fact is that during the production of electricity, heat is generated, which is simply thrown away at powerful central power plants. The thermal energy of the mini-CHP is directed to the hot water supply of the house. Thus, DHW will also be free for the user of a mini-CHP. Pretty tangible bonus, right?

Thirdly, its heat is cheaper. own mini-CHP is commensurate with the payment for connection to the central power grid. For example, in Moscow, connecting to the grid costs 45,000 rubles per 1 kW of installed electrical capacity. In a few years (from 2 to 6), the cost of installing a mini-CHP will pay off, since the annual cost of its maintenance is noticeably lower than the payment for electricity in local networks. According to experts, you can save up to 50 kopecks from each 1 kWh. Given that electricity prices are constantly rising, owning electricity will not hurt anyone.

Thermal insulation - a step towards independence

Logical conclusion: the less you consume energy, the less you depend on its source. This is not about saving energy by limiting its consumption, this principle does not at all correspond to the concept of "comfortable life". The question is different: how to keep warm in the house?

The warmer the walls, roof, floors of the dwelling, the less heat goes outside. This means that less resources are required for space heating. In Europe and the USA, energy efficiency (minimum consumption of thermal and electrical energy) of buildings has been thought about for a long time. Gradually, this trend reached our country.

The main factor in the energy efficiency of a building is high-quality thermal insulation. It is worth taking care of it in advance, even before the start of construction. Facade, roofing, pipes, ceilings, windows, doors - you need to minimize heat loss in all areas by insulating them well.

The first thing you should pay attention to when choosing a thermal insulation material is the thermal conductivity coefficient. The lower it is, the better. Hydrophobicity is also important - the ability not to absorb moisture, as well as reliability, durability, fire resistance, environmental friendliness, and ease of installation. And in some cases, you have to choose a material with a minimum weight.

Fibrous mineral wool thermal insulation (glass wool,) is the most common category of this housing construction product. Glass wool has a low thermal conductivity, it is light and fireproof. But fiberglass is subject to shrinkage. Therefore, after a few years, the quality of thermal insulation may noticeably decrease.

Stone wool is not subject to shrinkage, environmentally friendly and, importantly, durable. This is a non-combustible material. Stone wool fibers do not melt under the influence of fire, withstanding temperatures up to 1000 ° C. Moreover, in case of fire, such thermal insulation can significantly delay the spread of flames and restrain the collapse of structures. So in terms of security, this is probably the best option.

For example, ROCKWOOL ROCKFACADE (the world's leading manufacturer of stone wool insulation) can be used to insulate a façade. It not only performs its direct function - it keeps the heat in the house, but also protects the outer wall of the building from the effects of heat, humidity, wind and cold. The fact is that stone wool has a high vapor permeability. The air with high humidity, which inevitably appears in the living room, freely goes outside through the thermal insulation layer. Thus, the wall will always remain dry and last much longer.

If it is necessary to insulate floors, pitched roofs, attics, the inner surface of walls, floors along logs, lightweight ROCKWOOL LIGHT BUTTS boards with Flexi technology are suitable. This new product has a springy edge - one side of the material is pressed in and easily inserted into the frame and then straightened out in it. Any housewife can cope with warming.

High-quality thermal insulation will protect the house from both winter cold and summer heat. In any weather, the house will have a comfortable climate. Mini-CHP or kilowatts purchased from traffic - no matter how the heat is received, it must remain with you. For a cottage in which autonomous life support systems play the main role, this is especially important.

And we have gas in the cottage ...

An autonomous gas supply system in some cases is not just a desire to make your home independent of city gas services, but a necessity. Oddly enough, in our country, where, according to experts, the reserves of "blue fuel" will last for the next 100 years, there are still areas where one can only dream of main gas. However, in some places pressure drops in the central pipeline happen so often that it is time to think about your own gas storage.
It's quite real. A gas tank - a cylindrical container with a volume of several thousand liters - is buried underground at a distance of about 10 meters from the house. Once - three times a year, the tank must be replenished - with propane or butane. Such a system is designed for 20-30 years of service.

The cost of installing a gas tank is several times, or even tens of times, more expensive than connecting to a mains. True, in some regions of Russia, the prices for connecting to the central gas supply system are so high that your own gas tank is not much more expensive. It pays off its gas in a few years, since it is cheaper to operate than electricity from the central energy system.

…and your plumbing!

With central water supply in suburban villages, things are also not always the best. There are sections to which the water utility networks have not yet reached, and it is not known when they will reach. But this does not interfere with providing the house with clean water. No wonder the Earth is called the blue planet: we have water almost everywhere. You just need to drill a well of sufficient depth.

Neither a well nor a sandy well with a depth of 30 - 35 meters can provide the cottage with the necessary amount of water, and the quality of such water will be far from the best. These options are only suitable for cottages. For a modern country house, a well of several tens of meters is needed. In the south of the Moscow region, groundwater is at a depth of 40 to 70 meters, in the northeast of the Moscow region, it will be necessary to drill to a depth of 200 meters. What rock separates the site from groundwater - clay, granite, limestone - also needs to be considered. Everything related to water and soil on the site can be found in local well drilling companies.

Since drilling is an expensive process, it is better to think about the water supply of the house even before it is built, and even before the land is bought.

So, there is an opportunity to get your own water. This means that you can not depend on the presence of a central water supply system, buying a house or plot even in the corner farthest from the bustle of the city.

Clean air, a river, a forest ... Recently, more and more people dream of settling away from noisy and polluted cities. In our country, with its endless expanses, there are more than enough opportunities to settle in the bosom of nature. The only problem is that the more remote a cozy green corner is from the metropolis, the less conditions for a comfortable life in it. But man is a stubborn creature: if there are no ready-made benefits of civilization, he strives to create them. Therefore, own electricity, gas, water are becoming the norm. Modern technologies that help make housing autonomous, give the freedom to live where you want.

Extracting heat from the ground and water sources is not such an innovation. The Western world has long used geothermal energy for home heating. This topic is becoming more and more relevant as the prices of public utilities rise. A heat pump for home heating makes it possible to heat batteries in an environmentally friendly, safe and free way.

The heat pump heats the house with natural heat

Heat pump for home heating: principle of operation, advantages and disadvantages

A sample of a device similar to a heat pump is in every home - this is a refrigerator. It produces not only cold, but also heat - this is noticeable by the temperature of the rear wall of the unit. A similar principle is laid down in the heat pump - it collects thermal energy from water, earth and air.

Principle of operation and device

The operating system of the device is as follows:

• water from a well or reservoir passes through the evaporator, where its temperature drops by five degrees;
• after cooling, the liquid enters the compressor;
• the compressor compresses the water, increasing its temperature;
• the heated liquid moves to the heat exchange chamber, where it gives off its heat to the heating system;
• the cooled water is returned to the beginning of the cycle.

Heating systems based on heat pump installations have three components:

• A probe is a coil located in water or land. It collects heat and transfers it to the device.
• A heat pump is a device that extracts thermal energy.
• The heating system itself, including the heat exchange chamber.

Pros and cons of the device

First, about the positive aspects of such heating:

• Relatively low power consumption. Heating consumes only electricity, and it will require much less than, for example, heating with electrical appliances. Heat pumps have a conversion factor that indicates the output of thermal energy in relation to the electrical energy consumed. For example, if the value of "ϕ" is 5, then 1 kilowatt per hour of electricity consumption will account for 5 kilowatts of thermal energy.

• Versatility. This heating system can be installed in any area. This is especially true for remote areas where there are no gas pipelines. If it is not possible to connect electricity, the pump can run on a diesel or gasoline engine.
• Full automation. There is no need to add water to the system or monitor its operation.
• Environmental friendliness and safety. The heat pump installation does not produce any waste or gases. The device cannot accidentally overheat.
• Such a unit can not only heat a house in winter at an air temperature of up to minus fifteen degrees, but also cool it in summer. Such functions are available in reverse models.

• Long period of operation - up to half a century. The compressor may need to be replaced about once every twenty years.

This system also has its drawbacks, which cannot be ignored:

• Prices. A heat pump for heating a house is not a cheap pleasure. This system will pay off not earlier than in five years.
• In areas where the winter temperature drops below fifteen degrees below zero, the operation of the device will require additional heat sources (electric or gas).
• A system that takes thermal energy from the ground disrupts the ecosystem of the site. The damage is not significant, but this should be taken into account.

Ask a Question

“If you wish, you can make a heat pump for heating a house from a refrigerator with your own hands. But this will require some technical knowledge.

Which pump to choose

Installations differ in the source of thermal energy and the method of its transmission. There are five main types:

• Water-air.
• Ground water.
• Air-to-air.
• Water-water.
• Air-water.

Site survey

Before installing the heating system, it is important to examine the features of the site. This study will help determine which source of thermal energy will be the best option. The easiest way is if there is a reservoir near the house. This fact will relieve from the need to carry out earthworks. Another practical solution is to use a site where the wind is constantly blowing. If there is neither one nor the other, you will have to stop at earthworks.

The heating system can have two installation options:

• using probes;
• with the installation of an underground collector.

Ground-water pump and installation options

Geothermal probes are usually installed in a small area, the area of ​​\u200b\u200bwhich does not allow laying a large pipeline. To install this system, drilling equipment will be required, since the depth of the wells must be at least one hundred meters, the diameter is twenty centimeters. Probes are lowered into such wells. The number of wells affects the performance of the heating system.

If the site area is large enough, you can do without drilling and install a horizontal system. For this purpose, the coil is buried to a depth of one and a half meters. This version of the system is considered the most stable and trouble-free.

Water-to-water pump: easy installation

A water-to-water heat pump for home heating is suitable for areas with water bodies. For the pipeline, ordinary polyethylene pipes can be used. The collected collector is moved to the pond and lowered to the bottom there. This is one of the cheapest installation options that you can do yourself.

Air-to-air heat pump: installation price

In a site where winds are constantly present, a system that uses the thermal energy of air is suitable. Installation in this case also does not require special costs, it can be done by hand. You only need to install the pump no further than twenty meters from the house in the most ventilated place.

Heat pump for home heating: prices and manufacturers

Heat pump installations on the Russian market are represented by the products of Vaillant (Germany), Nibe (Sweden), Danfoss (Denmark), Mitsubishi Electric (Japan), Mammoth (USA) Viessmann (Germany). Russian manufacturers SunDue and Henk are not inferior to them in quality.

To heat a house with an area of ​​one hundred square meters, a ten-kilowatt installation is required.

Table 1. Average cost of different types of pumps with a capacity of 10 kilowatts

Image	Pump type	Equipment cost, rub	The cost of installation work, rub
	ground water Import manufacturers	From 500 000	From 80 000
	Soil-water domestic producers	From 360 000	From 70 000
	Air to water Import manufacturers	From 270 000	From 50 000
	Air to water domestic producers	From 210 000	From 40 000
	Water-water imported manufacturers	From 230 000	From 50 000
	Water-water domestic producers	From 220 000	From 40 000

The turnkey price of a heat pump is on average about 300 - 350 thousand rubles. The air-to-water system is considered the most budgetary option, since it does not require expensive earthworks.

Ask a Question

The possibilities of devices for remote control of heating every year (what's there every year - almost every month!) are becoming more and more perfect. Smartphone app developers try to make them easy to use and easy to understand even for untrained people. Briefly, we list only the main features of such systems that support:

• normal operation, when the set temperature is maintained throughout the house;
• zonal mode, when different rooms can have individual temperatures;
• prevention of defrosting of the heating system (freezing of pipes) in the cold season, when you are away from your country house or cottage;
• the possibility of early switching on the boiler, for example, you need to warm up a country house when you are going to visit it on weekends or holidays;
• always be aware of the operation of your autonomous heating and, if necessary, carry out its diagnostics;
• a temporary mode in which at different times during the day the house can maintain its own thermal regime with a significant reduction in material costs for fuel, for example, you can set the boiler to low power (respectively, to low fuel consumption), going to work or on business, and turn on normal mode before returning.

Remote heating control means that any of these modes, as well as specific room temperatures, are changed using mobile communications, or heating is controlled via the Internet.
This approach is part of the ideology of creating a “smart home”, which entails the further development of all engineering systems at home in order to ensure ease of use and create the most comfortable living conditions.

Which heating system can be controlled remotely?

In country houses and cottages, two-pipe systems with forced circulation of the coolant are currently most often used: the circulation pump pumps the coolant through the entire heating system, which, thanks to the distributor comb, can be supplied to each heater.
In such systems, as a rule, a safety block of the heating system is used to protect it from destruction in unforeseen situations, for example, in the event of an increase in pressure beyond the allowable one.
It is also necessary to have additional equipment to control the operation of the heating system: sensors, special valves and devices for adjusting the coolant flow, and it is also necessary to combine various devices into an information network

Weather-compensated heating control

To date, it is considered the most promising. In such systems, in addition to the room temperature sensor, an external air temperature meter is also used. In principle, a weather-dependent heating controller will work with one external sensor, but using two allows you to achieve more accurate mode maintenance and even implement self-adaptation of the system to specific temperature changes: if it gets colder outside, then the temperature of the coolant in the system rises in advance, if it is warmer - then decreases in advance. In addition to saving fuel, this reduces the inertia of the system, which increases its efficiency and also provides additional cost savings. One of the basic points of weather-dependent heating control can use a temperature of plus twenty degrees - with it, the temperature of the coolant is taken equal to the ambient temperature, while the heating is actually turned off. It is also necessary to take into account the zonal temperature control, i.e. if, for example, a large number of people gathered in one of the rooms, due to which it became hotter, the system detects a local increase in temperature relative to the one set by the weather heating controller, and makes a correction in this zone.
In general, serious battles flared up on the Internet about - is it worth using weather-dependent automation at all or is it money thrown to the wind? In short, the opinion of our specialists, confirmed, by the way, by the reviews of numerous customers, is unambiguous - yes, it is worth it, but not in all cases. And in what? Answer

Types of remote control heating systems

Currently, two systems are used for remote control of heating:

• using a set of equipment with an Internet gateway. The presence of a Wi-Fi router and the Internet in this case is mandatory.
• using a GSM heating control module. Requires a special GSM module with a SIM card from a mobile operator.

Remote control of the boiler room using mobile GSM

But what if there is no wired Internet in a country house? How can the heating be controlled in this case?

Yes, it's very simple - with the help of a special GSM module and, of course, a mobile phone. In fact, the GSM module performs the role of your personal assistant - you called him, gave him a command, for example, to pre-heat hotter by a certain time - and the whole family will come to a warm and comfortable house. Or vice versa, you forgot in the morning, leaving for work, to reduce the power of the boiler - it’s not a question, you can do it right from work, via the Internet or directly from your smartphone, while you still get to work.
The GSM module is a compact device with its own SIM card of any operator (it is important that it provides reliable signal reception in the given area), which allows you to control the indoor climate from any phone (satellite, mobile or fixed line), tablet or PC.

The undisputed leader in the market of GSM thermostats is currently the Russian company MicroLine. The company produces a wide range of GSM modules for remote control of heating boilers, including multifunctional controllers that provide control of the most complex heating systems.
You can buy in the appropriate section on our website GSM heating control

Depending on the settings you have made, your phone will either receive short SMS notifications with various information and instructions for changing the settings of the heating boiler, or you will receive phone calls with various information about the operation of the heating system. A special mobile application is installed on the phone (there are versions for Android, iOs, and Windows Phone), which allows you to directly remotely control almost all parameters of the heating boiler.
The GSM heating control module is essentially a computer docked with external sensors and having the ability to change the operating modes of the heating system. Naturally, the module must be in the zone of reliable reception of mobile operators.

GSM heating control module can operate in several modes:

• automatic, when, based on signals from installed sensors, the controller maintains the specified modes according to the specified program;
• SMS heating control when the heating system is controlled by sending SMS. In this case, when new data arrives, for example, about the temperature in the room, the controller accepts them for execution and begins to automatically support them;
• warning, by sending alarm messages about the current state of the house (gas leak, break in the water supply system, etc.);
• remote control of other devices connected to the GSM module (watering, lighting, alarm, etc.).

GSM - heating control allows you to remotely:

• receive indoor temperature reports;
• receive notifications about the current state of heating equipment;
• change the operating mode of the system by raising or lowering the temperature, including separately in each room.

Heating control is not limited to these functions. In principle, any heating system can be turned into a remote one. To do this, it must have an automatic mode of operation, and a special GSM controller must be connected to it to control heating and communicate with the subscriber.

Is this not enough for you? Then look at the possibilities of multifunctional GSM controllers, for example: ZONT H-1000 or ZONT H-2000 The devices are complex, require professional knowledge during installation and configuration, so only highly qualified specialists are required for installation - contact our company, we have them!

Remote control of the boiler using a set of equipment with an Internet gateway

Now consider the option of remote control of heating, if the country house or cottage has the Internet and, of course, a Wi-Fi router (aka a router).
Everything is much simpler here - you can see the capabilities of the devices proposed below and forever forget about worries about the state of the heating system in your home.

Salus IT500 provides control and adjustment of operation parameters in a maximum of two heating zones, for example, in the 1st room on the first floor of the cottage and the shower room on the second floor.
The kit includes an actuator (boiler receiver), a 2-channel room thermostat (weekly boiler programmer, boiler control panel) and an Internet gateway connected to an Internet router (router).

Possibilities of controlling the heating system using a set of equipment with the Salus iT500 Internet gateway:

• control of heating only modes (boiler and, if necessary, pump);
• management of several heating zones;
• management of heating and hot water supply of a country house.
• maintenance of different temperatures in different rooms, schedule of temperature regimes by days, hours and minutes
• 6 preset heating modes on delivery
• hot water heating control, automatic control modes, including energy-saving and "holiday" mode.
• a unique system for connecting devices via the Internet, providing reliable connection and control of the heating system: smartphone (or personal computer) -> Internet server -> router (router) -> thermostat -> receiver -> boiler

All equipment is wireless and communicates with each other via a radio channel, i.e. no need for electrical wiring. The room thermostat for the heating boiler is programmed for daily, weekly or 5+2 operating modes. The thermostat screen and applications for remote heating control display the current state of the boiler, the current temperature and the set temperature. Schedule setting can be done from the thermostat panel, web browser or mobile app.
The thermostat has a modern design, is highly reliable and safe to use.
With the use of additional equipment Salus Controls, it is possible to control, including remote control, underfloor heating, gas and electric boilers, oil heating systems, as well as almost any other heating systems and devices.
Remote control does not require a dedicated external IP address, the whole system works perfectly on any mobile Internet (Yota, Megafon, Beeline, etc.), it is also possible to control from computers and mobile devices on Android and iOS operating systems.

What to do if there is no wired Internet in the house, and a Wi-Fi Internet thermostat has already been purchased?

Most likely in the country there is coverage of mobile operators, isn't it? So you have internet! Just buy a Wi-Fi router with a USB port and in addition to it a 3G or 4G modem. Install a SIM card of any mobile operator in the modem that provides a reliable signal in the area where your home is located. You insert the modem itself into the USB connector of the router and that's it - now you have the opportunity to control the heating of the dacha remotely!

If for someone the iT500 seems expensive, the company offers a more budget solution - an internet thermostat Salus RT310i
The thermostat has somewhat reduced capabilities compared to its "big brother", but it can be a worthy replacement due to the lower price of the kit. Externally, the RT310i looks more modest compared to the first-class high-tech design of the iT500, it lacks touch controls, but the models are almost identical in functionality. Except that while the iT 500 is capable of controlling 2 heating or cooling zones, the RT310i can only control one zone.

Missing the features of the iT500? No problem - Salus iT600 can do it all and more!

If you do not have enough iT500 functionality to control only two heating zones, then on our website a more functional one is presented multizone(there are wired and wireless versions) system Salus iT 600 Smart Home. Well, something, and its capabilities for remote control of heating (and not only!) Will be enough even for the most demanding consumer!

Remote control of complex heating systems

The Polish company Tech Controllers, which produces a wide range of controllers with the possibility of remote control, is gaining an increasing share in this market segment.
By themselves, Tech controllers are multifunctional devices that are the main, basic part of the system, which can remotely control heating systems of almost any complexity using additional modules. There are a lot of possibilities, therefore, using an example, we will consider only the possibilities for remote control.

Tech Controllers Hardware Installation Example

In the photo for installation used:
1. Controller Tech ST-409n- a multifunctional device designed to control the central heating system, providing:
interaction with three wired room regulators
interaction with a wireless room thermostat
smooth control of three mixing valves
DHW pump control

weather control and weekly programming
the ability to connect the ST-65 GSM module for remote control of heating from a GSM smartphone
the ability to connect the ST-505 module, which allows remote control of the boiler via the Internet.
Possibility to control two auxiliary valves with additional modules ST-61v4 or ST-431 N
Ability to control additional equipment, such as garage doors, lighting or sprinkler, etc.

Various Tech modules can be used for remote control, it all depends on the specific needs of the owner. For example:

What if the heating system is so individual that none of the above solutions can fully meet the needs of its owner to manage it?
There are no hopeless situations! Most often, the customer himself simply does not understand (and should not!) All the possibilities of modern remote control systems for heating. It is really difficult for an unprepared person to understand all this abundance of devices offered on the market, which are completely different from each other in terms of functionality, price, and, of course, quality. Yes, and installers, often, simply have no idea about the possibilities for controlling heating systems - their task is to mount the system, but how often you will run around the house (or to the boiler room) and turn various valves to ensure constant thermal comfort, they do not care . Our specialists more than once had to almost completely remake the "creations" of such craftsmen, and this, believe me, costs a lot of money. A miser pays twice... Contact us, we will consult for free, and if necessary, we will install a remote control system for heating, we will help with the selection of high-quality equipment at an affordable price.

A modern wood-fired power plant is a very efficient and at the same time relatively inexpensive equipment, the main fuel in which is wood. Now this equipment is widely used in the private residential sector, as well as in small production areas and in field conditions.

The principle of the classical scheme

The very concept of "wood-fired" according to which a wood-fired thermal power plant operates must be understood that as a fuel, it is possible to use a variety of materials capable of burning. At the same time, firewood is the most common and frequently used resource. You can buy wood-fired power plants from a large assortment on the market at a relatively low cost. The main device of these types of power plants is:

• Bake.
• Special boiler.
• Turbine.

With the help of the furnace, the boiler is heated in which there is water or there may be a special gas for this. The water is then sent through a pipeline to a turbine. It rotates and with the help of this, electricity is converted in a specially mounted generator. Do-it-yourself wood-fired power plants are quite simple to make and it does not take very much time and significant financial investments.

Main features of work

During the operation of the power plant, the water will not immediately evaporate, but will constantly walk around the circuit. The exhaust steam cools and then becomes water again, and so on in a circle. Some disadvantage of such a scheme of operation of a mini solid fuel power plant is a rather high explosion hazard. If suddenly the water that is in the circuit overheats greatly, then the boiler may not withstand it and will burst it with pressure. To prevent this, modern systems and automatic valves are used. You can always buy a camping wood-fired power plant, which has high efficiency and safety rates at a very low cost.

Also, in the standard steam generator circuit, there are some requirements for the water used. It is not recommended to pour ordinary tap water into this equipment. Because it contains a large amount of salts, which over time will become the main cause of plaque on the walls of the boiler used and in the pipes of the power plant, which uses firewood as the main fuel.

Such a plaque has a reduced thermal conductivity, which will negatively affect the operation of a solid fuel power plant, which you can buy with any necessary operating parameters at the most affordable cost. But, now, the problems and difficulties with the formation of plaque can be quickly and easily solved by using specialized tools that are designed to combat the appearance of plaque. They provide an excellent opportunity to quickly and effectively cope with the formation of plaque in such equipment, which greatly simplifies the operation of power plants that use wood as fuel.

Various options for wood-fired power plants

Now very popular and inexpensive is a solid fuel tourist mini power plant, which can be purchased from a large assortment presented. Such power plants are very popular and in demand among a large number of tourists and travelers. This equipment uses a special solid fuel, which provides high efficiency, reliability and safety in operation.

A mini power plant using firewood as fuel is a fairly successful and long-used equipment that can be used in various fields of human activity. These types of power plants are very popular among summer residents, where there may be frequent problems with power outages, as well as in hard-to-reach regions where there are no power lines. In addition, camping options for power plants that use firewood or any other solid fuel elements are now becoming increasingly popular.
