How to mount warm floors from heating. How to make a warm floor from the central heating in the apartment: legal methods. Water warm floor - advantages and disadvantages

Warm water floors are comfortable and convenient, especially if they do not require the installation of a water boiler. In houses with radiator heating, it is possible to connect the warm floors to the heating system - this will allow water warm floors without unnecessary costs.

Project implementation

To perform warm floors, driven from the heating system, a number of conditions are needed. The heating system must be equipped with a circulation pump. With its absence, it is easier to spend and install a pump than to perform a gravitational system with a weathered slope of the floor circuit. The system can be both one-tube and two-pipe. With a single-tube system, the supply pipe of the warm floor is connected after the circulation pump, and the opposite is before the pump.

It is also necessary to calculate the length of the contours. For a two-pipe system, it must be no more than 50 meters, for one-tube - no more than 30 meters. If the heating circuit of the room turns out more, it is necessary to divide it into several contours, laid in different zones or in parallel.

Floor preparation

To avoid heat loss and not heating the slabs of overlapping, it is necessary before installing the heating circuit to prepare the surface of the draft floor.

If the floor already has an outdoor coating - it must be removed, the cracks are lined with cement mortar, and the surface of the floor is aligned with a cement solution or a thin layer of pure large sand. The surface of the floor is necessarily checked using a level on the absence of distillations - if the circuit of the heating floor will be laid unevenly, plots are formed with a slaughter of the coolant, which will worsen the heat transfer.
On the perimeter of the room, as well as at the junction of the heating circuits, you must install. The tape produces various widths, with adhesive layer or without it. The width of the tape must be chosen so that it is higher than the calculated height of the concrete screed. The mounting method is chosen depending on the walls of the walls. To smooth walls, the tape can be glued with an adhesive layer. Dowel-nails are fixed to the rough surfaces of the damper ribbon. The ribbon is necessary in order to cool the floor to be cooled, the screed destruction occurred.
After that, it is necessary to put solid thermal insulation on the floor, which will not allow heat to go down. This can be an extruded polystyrene in the form of plates or rolled foamed polyethylene with a foil coating. Plates are putting an online jack, not allowing gaps and cracks. Rolled materials are also joined, and the joints are sampled with a metallized scotch. Roll materials due to low thickness are rarely used, only if, due to a small height of the room, the use of a thicker insulation is impossible. On top of the insulation laid a layer of polyethylene film with a thickness of 200 μm - it is necessary in order to create the best conditions for drying the concrete screed and eliminate concrete.
Armature put on the floor. This can be a reinforcement grid with a cell from 10 cm, or a rod from a rod 6-8 mm, associated in places of intersection with wire. The grid is placed on plastic guides to create a gap between the reinforcement and the base.
To perform warm water floors from heating, special polystyrene plates with bins are convenient - they are designed to lay a water loop and do not require the installation of the guides. It should be noted that when laying polystyrene with bobbs it is necessary to use metal-plastic pipes, and not polyethylene, and the reinforcement is stacked after laying a water circuit.

Laying of water circuit and pouring screed

After the preparation of the floor, it is necessary to put the water circuit from metal-plastic pipes according to a predetermined scheme. You can also use stitched polyethylene pipes. Two ways of laying are usually used: "snake" and "snail". Laying "snail" is more profitable - the contour contains fewer corners, while the coolest reverse contour pipes pass next to the hot straight, which allows to avoid the so-called "zebra" - sections of warm and cold floors. The pipes of the water circuit are usually pinched with a step of 15 cm, for the southern regions you can use and step 30 cm. If you need to make the floor on any plot warmer, the installation step on it can be increased. The diameter of the water circuit pipes is chosen less than the diameter of the main pipes, otherwise the pressure in them will be insufficient.

Warm floor indoors is a great base for laying any finish coating: tiles, linoleum, laminate. With a warm floor with a water contour, there is one drawback - it has a significant height, about 10 cm. If the height of the room does not allow the warm floor from heating with a concrete screed device, you can perform warm water floors using or electrical with.

According to experts, the "warm floor" system is able to effectively heat the room of any volume and area even in conditions of harsh winter. At the same time there is a high level of comfort: on the floor is always warm, and at an altitude of about 1.5 meters the temperature is slightly lower. With such a thermal mode, human well-being is significantly improved. Convection processes capture the entire volume of the room, so it is much easier to maintain a comfortable microclimate.

Warm floor flaws

Heating of the floor with warm water is used quite a long time, but this method has not used popularity, since the life of metal pipes is not too much. The main disadvantage of water floors is considered complex, almost impossible repairs. The masters reluctantly poured metal pipes with a screed, as they quickly destroyed, and the dismantling of the concrete screed was complex and expensive.

As a result, the use of the system did not receive distribution. However, the construction market has evolved, and pipes made of metalplastic, which are characterized by high quality and good flexibility. Therefore, water warm floors began to be used first in parallel with radiators, and then instead of them. With the appearance on the market of pipes from stitched polyethylene, water warm floor began to gain popularity, since the material was distinguished by high quality characteristics and a relatively low cost.

Another minus is a big height of the whole cake, in most cases it is about 10 cm. For premises with low ceilings, this fact is of great importance.

Among the disadvantages of such a method of heating also highlights greater inertia. To heat the floor and the room to a comfortable temperature requires a lot of time and heat. Consequently, the water warm floor is best used in the places of permanent stay, and not a temporary visit.

Features of the connection of the warm floor to central heating

In the apartments of multi-storey houses of the water heating floor system connect to a riser of centralized heating. For this, the housing and operational organization should provide a special permit. However, it is not always possible to get such permission. Most often, such documents without problems are given for apartments of newly built houses, they provide a separate riser to connect the "warm floor" system.

In the apartments of old houses, the installation of a warm floor can become problematic. The fact is that in such houses in most cases a single-tube heating system is installed. When the warm floor is connected from the riser, a large amount of heat will be consumed, as a result, the radiators of apartments located on the floors below will be constantly cold. Therefore, permission to connect the warm floor to the central heating system can be issued to the owners of the first floor of the house.

It is possible to solve the question of how to make a warm floor from heating, you can connect warm water to the boiler. Such a system requires large financial costs to install special equipment, however, during operation, expenses become significantly lower. Another options can be called the installation of electric heating floor. This option has a significant advantage: upon failure of a separate section, the entire system continues to function.

When issuing permission to connect the warm floor of the WEO may require the installation of heat meter. This should be accounted for without a doubt, since with good thermal insulation you pay for the meter much less.

Warm floor installation process

The first stage in solving the problem, how to make warm floors from water heating, is the preparation of the project. It is necessary to draw room plan with the size of individual rooms and the location of the risers. Near the riser to which the connection will be performed, the collector node should be placed. On the one hand, central heating is connected to this device, and on the other hand, the pipes of the "warm floor" system. The collector node has a temperature sensor that allows you to control the heating of the coolant. Also in the device can be a valve or valve, with which a certain temperature is installed for each contour.

The water heating system requires the mandatory mixing of the hot water of the feed pipe with a cold from the return pipe. This happens in the collector node, which is additionally called the mixing node. This is explained by the fact that sometimes there can be a fairly high temperature at the feed, at which it is not entirely comfortable on the floor. The device in the mixing unit that controls the temperature of the coolant gives a signal about the need to add cold water.

For impeccable and efficient operation of a water-free system, a circulation pump is required. It is designed to provide a certain water speed along the contour of the warm floor.

The next step will be the choice of type of pipes for the waterfloor water system. For this purpose, pipes are used from metalplastic or cross-linked polyethylene. However, recently the popularity of corrugated stainless pipes is noted. This material is characterized by flexibility, reliability and relatively low cost, lower than the price of metal-plastic products. In addition, pipes have a long operational period and have no fakes yet. The only disadvantage of the corrugated pipe can be called high resistance to the flow of the coolant due to the ribbed surface.

It is also important to determine the method of laying the water circuit pipes. Two methods are popular: "Snail" and "Snake". It is easier to lay snake pipes, but the snail warms the surface of the floor uniformly, there is no alternation of a warm and cold zone.

The diameter of pipes for water heated floor and their length is not less important. In most cases, a pipe with a cross section of 16 mm is used, as for the length of the contour, then a standard of 4-5 meters is taken as the basis for heating one square of the area.

Pipes should be laid according to a pre-compiled scheme, otherwise it may not work. Even a simple snake is quite difficult to lay on a small area, where no more than three contours is located. In this case, the length of each contour is about 30 m, and both ends must be connected to the collector node.

Installation of the "Warm floor" system from heating

Many homeowners are interested in the question of how to make a warm floor from heating. To solve quite consistently perform all activities.

If the work is carried out in the old apartment, then the first step should be dismantling outdoor coatings. With wooden floors, it does not occur most often, but with tiles in the kitchen and in the bathroom will have to tinker for a while. In any case, the coating must be removed.

At the next stage, the surface is aligned. The normal functioning of the system is possible only on the smooth floor, with significant height differences, the coolant can be observed. If the irregularities are small, then it can be applied to the surface of the cement mortar. On the smooth floor should be seen available pits or cracks. Solve the problem also helps coarse sand, applied by a thin layer, it is necessary to sprinkle well.

The continuation of the work is the sticker of the damper tape throughout the perimeter of the room. In this case, one part should be attached to the wall, and the second one - to the floor. They are glued to the smooth surfaces with ribbon, they are nourished with a dowel. The damper tape will protect the tie of the warm floor from cracking in the case of temperature expansion.

The most important point when installing the warm floor from the central heating with their own hands is the insulation of the surface. The most popular thermal insulation material in this case can be called foil foam polyethylene or extruded polystyrene foam. To facilitate the assembly process, some types of insulation are equipped with special guides, but in this case only metal-plastic tube is used as the heating element.

The thermal insulation material needs to be laid tightly so that cold bridges are not formed, contributing to the loss of heat. Therefore, the places of stoves or rolls of the insulation are sampled with a metallized tape.

On top of the thermal insulation, special grids with cells are placed on top, to them with plastic clamps or knitting wires pipes will be attached. In the process of laying, a certain step is held between two adjacent pipes in the circuit. Moreover, this value depends on the climate in the region and the room temperature requirements:

In the southern regions, the distance between the pipes is recommended to do about 0.3 meters.
In the middle of Russia, it is enough to position the turns with a step of 0.15 meters.
Indoors where high air temperature is required, placed pipes at a distance of 0.15 meters.
In the central part of the room you can withstand a gap 0.2 meters.
Under the pipe furniture is trying not to stack, but if necessary, the installation step can be 0.3 meters.
Sections of the room near the outer poorly insulated walls, near door and window openings require more frequent laying of pipes, in this case the step can be 0.1 meters.

The ends of the laid pipes are displayed to the collector node, are connected to the appropriate nozzles and fixed with special clamps. The system is filled with water and leave for a while. In order for the test of warm floors from steam heating to be more efficient, and all defects have become explicit, it is necessary to submit a heat carrier under high pressure and with a temperature of about 50 degrees. In the absence of problem areas, you can pour a finite concrete tie.

Work at this stage is carried out when the contour is filled. First of all, beacons are exposed, at an altitude of 5-6 cm from the pipes, it is precisely such a layer of concrete must be over the heating element of the water warm floor. Next, proceed to the pouring of the concrete solution. It is best for this purpose to use the composition of the M200 brand with fine-grained filler. Spray tie lines using the rule. The whole design should simultane at least 4 weeks so that concrete scored the required strength. After this time, the finishing floor covering is placed and prepared a room to operate.

Connecting a warm floor from the boiler heating

In the event that there is no possibility of connecting warm water floors with their own hands from the central heating battery, you can buy a heating boiler. Such a device is quite expensive, but allows you to create an individual heating system. This option is obtained more profitable during operation, even with the most expensive fuel.

Installation work on the arrangement of warm water floors from the boiler is carried out by the same scheme as in the case of central heating. The sequence of actions is also saved, except that the collector is not connected to the riser, but to the boiler heating.

Connecting the "Warm floor" system to the boiler cannot be called complicated, the work can perform a homely master without attracting professionals. On the feed tube, the security group is installed and the pipe from the boiler to the collector node to which the water circuit is already connected. On the inverse tube, the expansion tank and the pump for forced circulation of the coolant are mounted.

Water warm floor in the apartment can be connected to central heating or a boiler. Each option is characterized by its pros and cons. The effectiveness of the warm floor from the central heating is determined by the work of the boiler room, the costs in this case are quite high. Heating boiler and its installation is expensive, but further payments for heating are significantly reduced.

Use the heating floor to create more comfortable conditions began during the time of ancient Greece. In the modern world with the development of technologies, everything is much easier. The warm tuned floor in the apartment is applied in any climatic conditions. Depending on the decrease in the temperature outside the window, it is a full or additional heating system.

The cheapest and economically beneficial is considered water warm floor in the house. The coolant is water heated by the boiler, and when accommodation in the apartment - central heating.

Warm floor water with their own hands has good and bad sides. Before making a warm floor in a private house, you need to take into account them all.

What are the advantages of water heating:

Such a system provides comfortable thermal conditions. Heat rises from the bottom up. It warms the entire room. This is especially true in private houses with high ceilings.
When the legs are warm, lowering the ambient temperature imperceptibly located in the room.
Since the warm floor from heating is a low-temperature heater, it does not dry the air.
The heater uses water temperature much lower than necessary radiators. The use of such a system for heating in a private house is well combined with condensation boilers or thermal pumps.
It is possible to disable part of the contours from the system.
Heated concrete long retains the temperature and in the room is supported by a stable thermal mode. It works well when using solid fuel boilers.
All laying of water underwear is hidden in the floor and does not disturb the overall picture of the room.

However, there are also a number of shortcomings that should be paid attention to, arranging water warm floors in a private house:

It requires high-quality execution of all stages of installation before pouring the warm floor. Correction of errors or malfunctions at the end of the work - the case is financially costly, and sometimes impossible.
Warm water floor in the apartment can be made only with the permission of the relevant government bodies.
Slow and slight adjustment of warm water floors. Using the heating boiler, you can customize the warm floor on a small range, in the apartment with central heating it is impossible to adjust at all.
Not all sorts of coatings are combined with warm polo. They are not recommended to install bulky furniture or retain carpets.
The thickness of the warm floor is about 10 cm. It must be considered when designing the room as a whole.
The insulation of inter-storey floors increases the load on the beams.
The installation of circulating pumps and thermostators is required.
The device of such floors is quite expensive.

Weighing everything and against, it is impossible to say that make warm floors, it will increase comfort for a small surcharge. Although many masters can make a water warm floor in the house with their own hands. Performing a number of important rules, you can achieve positive results.

Mounting process

All installation of water warm floor in a private house consists of several main processes. Performing each correctly, craftsmen get a warm water floors in a private house, working securely up to 50 years.

All work consists of:

design;
insulation;
laying pipes;
crawling of finished floors.

Each part has its own pitfalls. You need to get acquainted with them.

Project creation

By installing water warm floor with your own hands, you should correctly calculate the boiler power. With a shortage of power, water will not be warm enough, which will affect the quality of heating. Power is usually taken more by 15-20% of the total power consumption.

Each water is performed by a solid pipe. To calculate length, you must first perform the drawing of all circuits on paper. The following pavement scheme is indicated and the place of the collector fastening.

The diameter of the pipe and the step of laying water underground depends on the surrounding conditions and is calculated when designing. It makes sense to order a project in specialized organizations. With incorrect calculations, warm water floors in a private house will work badly.

Warming of water heating

So that the warmth of the warmth is home, not the land or ceilings in the next apartment, use a different insulation for a warm floor, which is stacked on a prepared level basis. Drops in height cannot be higher than 5 mm. The system will warm up incorrectly and not long.

Between the base and insulation, the hydrobarier is necessarily located. He protects the floor from the penetration of moisture from the ground. The overlap of the polyethylene film is performed. If the pieces are sprinkled, then they are superimposed, and all the seams are squeezed with scotch.

The insulation for water heated floor is from various materials. Application must be reasonable to the place, ambient temperature and the type of base.

The following insulation are most popular:

Polystyrene foam. It is used when insulating the first floors on the ground or cold basement. This insulation under the warm floor has a high density. Released in different thickness. The greater the thermal insulation, the thickness of the plates are used.

In the absence of plates of the desired thickness, you can put more subtle in two rows, saming them between themselves.

Mineral wool. She enjoyed when creating water heating in wooden houses. It keeps very well warm and fills all the space. The disadvantage is in hygroscopicity, it is necessary to reliably protect it from moisture.

Profile thermal insulation is the most modern insulation for warm water floors. It is with laminated coating and grooves or bobbers that help subsequent laying of pipes. The only minus of the thermal insulator is its price.

Thermal insulation for water heat is available in the form of plates. Their styling usually does not occupy a lot of strength or time. All seams or joints must be glued with a foil scotch for avoiding moisture and reducing heat loss.

On the perimeter of the walls, the entire cake of the warm floor is separated by a damper ribbon. It is laid along all walls, the remains are cut after the screed. The tape serves as a compensator of temperature stresses.

From above, the insulation is a waterproofing layer to protect it from the effects of moisture or aggressive medium (concrete, cement). It is also recommended to cover the insulation with a foil layer for better reflection and distribution of heat. In practice, it works only for wooden set floors. When pouring concrete is just an excessive waste of money. When using profile plates, all these actions are lowered.

Laying pipes

To mount water heating, copper, metal-plastic and polypropylene pipes with a diameter of 15-20 mm are used. The diameter of the pipe depends on the size of the room and weather in this region.

Pipes with a diameter of more than 20 mm are not used. To adjust in them the right water pressure requires very powerful boilers and pumps. It is inappropriate from the point of view of energy expenses.

For installation, two schemes of laying water heating pipes are used:

Snake scheme. This is when the pipe is uniform snake unfolded over the entire surface of the room. With such a layout, it turns out hot water, then it gradually cools, and the cooled returns to the reverse. It is recommended to use in sanitary facilities (bath, toilet), corridors and small rooms, where the length of the contour is small.
Schema snail. For large rooms, it is recommended to lay pipes with a spiral, starting with the middle. It turns out the alternation of pipes of different temperatures. Heat is distributed evenly. The hottest pipe is placed along the outer wall to compensate for the outer cold.

The gasket of each contour is performed by a solid pipe. All bends are made smooth. The distance between the heap pipes is 7-20 cm. The wall interval is 5-7 cm.

For a better warming of water warm floor in a private house between the closed pipeline and the next twist, the pitch laying step should be 5-7 cm, then, how to adjust the laying of water warm floor pipes is calculated in the plan.

Pipes are attached with special guides. Still use the reinforced grid. It is located above the insulation, and already to it with the help of wire or plastic clamps fasten the pipes.

When fastening for rotation, at least 3 brackets are used

When heating and filling with water, the pipe is slightly expanding. Attaching them, it is necessary to take it into account, leaving a small gap.

When using profile plates, the pipes are simply placed in the grooves or between the buses. The length of the pipe is not recommended to exceed more than 100 m. Optimal is considered 60-80 m. If the room is large, you need to lay a lot of heating circuits.

Collector

One of the main elements is a collector. It connects the contour of the pipe to heating. All contour must have the same resistance. The collector is two nozzles to which the contour of the heating connecting to the reverse and supply of the boiler are connected.

The temperature of the water heating floor is within 35 ° C. To configure and smoothly change the temperature, the mixer and thermostar are connected to the collector.

The collector must be installed above the heating level for the possibility of air output from the system through the special air. Turning tap. It makes sense to equip it with two locking valves for the possibility of repairing or replacing parts without draining water.

Pipes join the collector with crimping. Before pouring the warm water floor, tested tightness. The system is filled with water or air, a pressure of 1.5 workers, and left for two days.

Pressure may slightly decrease due to a small stretching of pipes.

Execution of tie

After checking the tightness, the warm floor is started.

Screed for a warm floor can be different:

Concreting (wet method)

When performing, a solution of concrete or cement is used with the addition of a granite dropout.

Sand as part of a concrete screed over a water warm floor is not used because of its low thermal conductivity.

To increase the life of the fill of the warm floor, reinforced. For this, a metal or plastic reinforced grid is suitable. On the Internet there are many step-by-step instructions, how to fill the warm floor correctly. Plasticizer and polypropylene canvas add the screed. This significantly increases the service life.

When the screed under the warm water floor is performed, the pipes are under pressure.

The thickness of the screed for water underground depends on the subsequent coating and varies between 3 cm and 7cm. If several contours were performed, the fill of the water warm floor around each part is performed separately. Between them there are compensation seams from the damper tape. The flooded screed of the warm floor will dry during the month. For uniform drying and high-quality setting, it is necessary to water water sometimes.

Polystyrene system

With this system, the laying is obtained water warm floor without a screed. It is used when creating heating in wooden modular houses and for the insulation of intergenerational floors.

The pipeline is mounted on polystyrene or wooden plates with grooves without a concrete screed.

When the tree is used, the insulation under water warm floor is used in the form of a mineral wool laid between the lags.

Putting the pipe into the groove, it is covered with aluminum plates from above, which are attached to the plates with special locks. When collecting a warm floor under the tile, it is necessary to supplement the cake of the chipboard of the chipboard, moisture-resistant plywood or GVLP. When using laminate, it is placed on an aluminum profile.

More often used concreting screed for a warm floor. The flooded solution is better maintaining heat, with this installation, the warm floors in the house will serve over 50 years. When, due to circumstances, it is impossible, then a dry screed is used, although the heat transfer will be worse.

To cover the warm floors, a stone or ceramic tile is suitable. It easily warm and keeps warm well. Still used for laminate floor or linoleum. Such outdoor material must necessarily have a mark of the possibility of their use with warm floors.

Having attached to the effort and investing some means, you can warm your home for a long time. There are many sources of information, how to make a warm floor correctly. An optimistic attitude and skill is important. The warm floor will bring comfort to many generations living in the household house.

Many experts argue that the warm floor is a self-sufficient heating system, which effectively hesitates the premises of any size and cube, even in the north of Russia. At the same time, the level of comfort increases: the legs are always warm, and at the level of 1.5-1.8 meters there is some decrease in temperature. Such thermal regime according to the statements of doctors is the most optimal for good well-being. In addition, when heating the floor, convection processes affect the entire amount of air indoors, which reduces the cost of maintaining a comfortable microclimate.

Disadvantages of water floors

The idea of \u200b\u200bheating the floors of warm water is far from Nova, but due to the lack of durable pipes, it has not been implemented long for a long time. There is a large minus at the water floor - the complexity, almost inability, repair. Therefore, until recently, such systems were not very common: Metal pipes are unreasonable in the screed. They quickly destroy, and break the screed for repair - difficult and expensive. With the emergence on the market, warm water floors began to be used more often. Somewhere together with radiators, and somewhere instead of them. And all because the MP tube of a good quality can serve as decades, well bent, sold in bays with a length of up to 200 meters.

But the impossibility of repair is not all flaws. There is another significant minus - the entire cake of the warm floor from hot water takes about 10 cm. If the ceilings indoors and so low, it is a lot. In this case, it is better to do. It is only 1-2 cm.

Another minus is a big inertness of this method of heating. Of course, an array of screed, in which pipes are stubborn with a coolant, gently dispels heat, giving comfort. But there is a lot of heat for heating. And if you consider that for comfortable sensations, the temperature of the water in warm floors should not exceed 40 o C, then it is clear that while the screed is warm, it will take a long time. That is, such heating is optimally for permanent residence and is not suitable for places where you appear periodically: quickly heat the room water can not.

Warm floor from central heating: Legal nuances

If you have an apartment in a multi-storey building, in some cases, a warm floor can be powered by a standing of centralized heating. The installation of this type of heating requires a special permit from the housing and operational organization. If the apartment is located in the house of the new building, most likely the permission will be given to you. In new buildings, a separate riser is usually provided for connecting this type of heating.

There may be problems in solid age houses. Especially if you have a single-pipe layout (this is when there is a separate riser in each room and the battery is connected from it). The fact is that with such a connection system, if you take too much heat from the riser, the neighbors will come to the radiators at all cold water. With a single-tube system, only apartments can get permissions on the first floor. The rest - hardly.

If the desire to warm the floor is, and the permission is unrealistic, you can power the warm floor from the heating boiler. The device of such a system will be more expensive at the installation stage, but the monthly costs will unambiguously be lower. Or another option - to lay the electric warm floor. It can be even a more attractive option, since when using the failure of one segment does not affect the work of the entire floor. Since the segments are very much, you will not even notice that something broke there.

What does "Pie" water heating look like

If the heat-mall device in your house is probably most likely as one of the conditions for obtaining permission, the requirement will be put forward to install heat meter. Agree without thinking - if you do everything as it should (mean insulation), it will be more profitable for you, since you will pay less.

How to do

The first step towards making a warm floor in the apartment (from central heating or from a boiler - no difference) is the project drawing. Transfer the room plan to paper, indicate the size of the rooms and the location of the risers. Near the risers from which it will be powered, you need to find a place to accommodate the collector node. This device to which is connected on one side of the input / output of the centralized heating system, and on the other pipe located in the floor. It also contains a coolant temperature control device, and sometimes valves / valves for temperature adjustment in each circuit.

The peculiarity of the warm floor from heating is that hot water from the feed must be mixed with the cold, which is closed from the return pipeline. Therefore, such a node is sometimes called mixing. Let not always, but in the feeding there is a temperature of 95 o C and even higher. Imagine your feelings if water with such temperature will warm your gender. Africa rests. Here for this, you need a node for controlling the temperature of the coolant, which, if necessary, adds cool water.

The speed of water in the heap system should be within 0.2-1.0 m / s. In order to ensure such speed, the scheme requires (without it is ineffective).

Then you need to decide on the type of pipe that you will use. Until recently, there were only two options: or stitched polyethylene. Today there is a third, which at first glance does not have the shortcomings: corrugated stainless steel. Flexible, reliable, inexpensive (much cheaper than MP), long service life, excellent characteristics, and there are no crafts. Not material, but a fairy tale. Of the disadvantages - only greater resistance to water flow due to the ribbed surface. And that is not proven fact, but an assumption. In general, note that there is also such a material. More

After it was decided on the type of pipes, decide how they would be laid: "snake" or "snail". "Snake" is easier in laying, "snail" does not give the effect of zebra - alternating warm and cold zones. Then you need to select the diameter and find out the length of the pipes. For water floors, there is no sense in the apartment of a special meaning - there is no heat engineering - everyone uses a pipe 16mm. It is unlikely that the calculation you will get something else. You can estimate the length normally: 4-5 meters of pipe on M 2 area. Now you can proceed to manufacture.

Scheme laying a warm floor "Snake"

The scheme of connecting water warm floor to the boiler is not different. A security group is installed on the supply pipeline (if it is not in the boiler), then the pipe from the boiler is started at the collector node. The headlight contours are connected to the collector node. On the return pipeline there is an expansion tank and circulation pump (again, if it is not in the boiler). That's the whole strapping of the boiler for connecting warm water floors. The simplest diagram is shown in the figure there is a table of specifications.

RESULTS

The source of the heat carrier for water underground floor in the apartment can be a riser of centralized heating or boiler. Both options have advantages and disadvantages. First, the warm floor from the central heating can not always be powered by always, and secondly, you still depend on the work of the boiler room, thirdly, pay for this decent money. When using the boiler you get a self-operating warm floor, but spend more money on its device (the boiler is expensive), but save on monthly pay for utilities.

In recent years, warm floors are simply unprecedented demand. It is associated with such an increase in demand for technology not only because of the peculiarities of the domestic climate (we have been cold in the country for almost six months), but also due to the unsatisfactory work of utilities (often, heat from batteries is simply not enough for a comfortable stay).

Durable and reliable, productive and inexpensive heating system in the form of a warm floor will help to warm up any room, eliminating the need for additional installation of individual elements and some repair work.

Warm floor and its heating connection

Today, there are extremely many variants of warm sex systems, but those who work on a liquid coolant (most often) are most popular. At the same time, "feed on" such warm floors from heating or a specially created autonomous contour.

Of course, due to some features (availability and simplicity, in particular), the option is most often used when the warm floor is connected to the centralized heating system.

The warm floor in the apartment from central heating allows you to achieve the highest productivity and heat transfer efficiency, reducing the accompanying costs almost an order of magnitude. In addition, if you come to the organization of the process with the mind, then all preparatory and installation work can be performed in the shortest possible time.

What you need to know before starting work

Before organizing a warm water field from central heating, it is necessary to take into account some nuances:

Before starting any installation work, it is necessary to take into account the fact that the water heated floor from the central heating creates an additional load on the entire system. Naturally, heat loss is rising, and therefore without coordination with specialized bodies just can not do.

Yes, and utilities can easily force the newly minted owner to establish a special consumption counter of warmth.

Installation of warm water floor: options and main stages

Instructions for warm floors connected to the central heating system implies laying all pipes in several main ways:

Spiral (Bifilar);
Spiral with a displaced center;
Meander (snake);
Laying double zigzag.

It should be noted that each existing option has its own positive and negative sides - the choice should be based only on their own preferences, as well as on the basis of some other factors. In particular, in those places where doorways, window openings and walls are located in the room, the coolant must have a higher temperature.

Council. If it is difficult to decide on the laying of a heap pipeline, it is best to choose a snake.
This is a universal version, thanks to which you can provide the most optimal heat transfer, eliminate breakdowns and other troubles.

The process of organizing the work of the modern heating system itself consists of several stages that have features of execution, which should be given considerable attention:

Preparation. Do with your own hands it is necessary to clear the basis for which the pipes will be laid,
Also, it is necessary to divide the entire area of \u200b\u200bthe room on the functional areas - small areas, which will further help increase the efficiency of the process, reduce the cost of time.

At the preparation stage, there is also laying of thermal insulation materials. Due to this layer of isolation, it is possible to reduce the loss of heat, eliminate extra financial costs;

Council. When laying thermal insulation, it is necessary to smoke the edge of the materials using a special elevation ribbon. Thus, it is excluded to shift the materials when they are installed, and work is simplified.

Council. Sandobeton M-300 can be used as a solution.
Such a concrete has the most optimal combination of price and quality, and its thermal conductivity and operational characteristics allow you to obtain a more efficient and productive system of heating.

Laying outdoor coating. Before installation, it is important to wait at least a pair of day - during this time, the concrete will fully acquire its qualities, "matures".
At the same time, the choice of material for flooring can be the most diverse (and it can be seen in many photos and video of apartments with warm floors), for example, parquet, linoleum, laminate;
First launch and testing of the installed warm floor. Best of all, if representatives of utility services are present on the launch - in case of any faults, it will be possible to quickly overlap the flow of the coolant in the apartment.
