Which boiler for home is 120 sq m. Gas boilers. How to correctly calculate the power of the boiler for heating a certain area

In the modern market of heating systems, you can find a huge selection of both budget variants of gas wall boilers and "flagships", which are distinguished by an improved protection system, longer service life and higher efficiency.

Consider the most common models of wall gas boilers to heat the room in 120 m2.

How to correctly calculate the power of the boiler for heating a certain area?

According to the passport data of manufacturers, the heating gas boiler is selected at the rate of 1 kW per 10m2. However, this is a rather caught figure, since the quality of the insulation of the house, the material of its manufacture, climatic zone, etc. plays an important role.

Well, for example, we take to heat the frame house in 120 m2 on the basis of the above calculations would have enough gas boiler at 12 kW. However, in fact it is extremely small. In addition, if you still need hot water (double-circuit system), then 18 kW is not enough.

For heating of such a house, the most rationally install double-circuit gas boilers with a capacity of 24 kW to ensure power reserve. Pretty well proved boilers BAXI, PROTHERM, VIESSMAN, VAILLANT.

What is better to choose a wall gas boiler for 120 sq. M.

Of course there is no definite answer to this question, it all depends on your need. Well, for choosing you have 2 options (without taking into account manufacturers):

• Single-mounted;
• Double-circuit.

Single-mounted heating boilers

These devices are designed exclusively for heating the room. Their price is much lower than double-circuit, however, in the absence of hot water, you must additionally buy a boiler.

They are most often installed in high-rise buildings, which are connected to a centralized supply of hot water.

Double-circuit wall gas boilers for 120 sq. M.

This is the most common type of heating boilers. Since in addition to the heating of the room, they provide you with hot water and the efficiency of these systems reaches 109% (boilers Viessman Vitodens 200-W).

This is the perfect solution for cottages, private houses, offices, etc. They have proven themselves as energy-saving devices with high functionality and ideal efficiency.

The need for thermal energy to heat the building and, accordingly, the power of the heat generator does not least depend on the climatic conditions

On the Internet "walks" the figure of 0.1 kW per 1m2. Indeed, for the heating of an abstract square meter in the average typical house built in accordance with the time of the USSR long-based heat engineering standards, approximately 0.1 kW per 1 m2 heated total area. This is 12 kW at 120 m2. But again, this is an irrelevant "average temperature in the hospital" without taking into account the characteristics of the structure and climatic conditions of the area.

If you want the most accurate and rational to choose the heating equipment, use not "mid-station" data, and calculate specific numbers for your home

By the way, how are you going to warm water for water supply? Probably want to install a storage boiler of indirect heating. Often it is recommended not to increase the boiler power specifically for the preparation of hot water. Like, the scope of the boiler is great (usually over 100 liters), the reserve of hot water is large. It is fast, it will not end and there is no need for an emergency water heating, as in a two-circuit boiler. However, it should be borne in mind that modern boilers have the priority of cooking hot water for the needs of water supply. That is, if on Friday you all family take turns take a bath, you will turn off the heating for a few hours, while the water temperature in the boiler does not reach the specified. In the cold climate, this can be significantly and possibly the power of the boiler should be increased according to the needs of the DHW. Alas, this will not save it from the temperature of the coolant, only reduce them.

You can avoid such a situation by installing intelligent automation or manually changing the heating modes. But rational is well insulated the house, then the temporary drop of the temperature of the coolant will not lead to tangible cooling.

Heating for a house of 120 square meters. meters

Select the method of heating a residential building is primarily based on the presence of a particular type of fuel. What better to fuck?

We offer the 4 most optimal options for the heating of the house with an area of \u200b\u200b120 m2.

Option 1: Gas heating

This option will be the most economical. Therefore, if the main gas pipeline is connected to your home, it is advisable to choose this method of heating.

The system with a gas boiler can work completely independently without monitoring the owners of the house.

Benefits:

• Low costs
• Full automation
• Convenient management

Of the disadvantages, it is possible to note difficulties with connecting to gas.

If you do not have the opportunity to give a house with natural gas, you can consider the option with a diesel boiler.

Option 2: Diesel fuel

The heating system on diesel fuel is fully autonomously. To store fuel, you will need to install a special plastic container. It can be installed as in the house, the same on the street.

Otherwise, this system is the same as when gas heating.

diesel boiler house in a private house

Benefits:

• Full automation
• Comfortable and comfortable management

Disadvantage - High heating costs at home.

For example, for heating a residential building with an area of \u200b\u200b120 square meters. m. It will take about 60,000 rubles a year.

Ready example of diesel heating at home 120 kV. meters

Option 3: Electric water heating

This method is the least economical option for the heating of a residential building. However, the initial investments will not be as large as in diesel heating.

Another advantage is compactness and simplicity of installing the boiler. It can be installed in any room.

This method is well suitable for giving. During the absence of hosts, you can include the minimum mode to save electricity.

Please note: for a house of 120 square meters. m. It is necessary to have an electrical power of 12 kW.

Watch a ready-made solution for electrical heating at home

How much money goes to the electricity in the apartment - it is easy to count. Go to the meter and look - and so every month. What is in the apartment? Washing machine, TV, computer and a dozen light bulbs.

A completely different song is a private house. It is sometimes impossible to understand where such a figure comes from even those who live in the house.

And if you are still a town dweller? If you still have to build plans, and you are afraid that you can not serve it?

Here we will help our calculations "by top" - where electricity in a private house goes.

Cost of heating with electricity in the house

The most expensive article cost in a private house is the cost if you have an electric boiler. At the cost of 1 kilowatta per hour in the area of \u200b\u200b3 rubles, let's consider what it will do.

For simplicity, we will take the area of \u200b\u200bthe house at 100 square meters. And then everyone can count, what he will do heating his house with a concrete area.

For every 10 square meters of a well warmed house you will need 1 kilowatt power of an electric boiler. At 100 square meters you need a power boiler at least 10 kilowatt.

Electricity consumption 10 kilowatt per hour - the boiler will work continuously. Total 240 kilowatt-hours per day. If the frosts under -30c will have a month, then your electric boiler consume 7200 kilowatt-hours of electricity. Not weak? More than 7 megawatt for the month! What will cost you more than 20 thousand rubles only for the heating of your home.

However, in practice, such frosts are in the middle lane of Russia and even in the Urals no more than 1-2 weeks for the winter. Sometimes, in some winters, however, tightening frosty periods occur, such as in the winter of 2013.

The rest of the time when the winter temperature fluctuates at -15С -20С, the boiler works half the time. That is, your approximate cost of home heating at 100 square meters will be equal to 10 thousand rubles per month.

This is the winter months - December, January and February. In November and March, the boiler will work only 8 hours a day at full capacity, or stepwise consume only a third of electricity. This means that in November and March, your electricity costs for heating at home will be approximately 6-7 thousand rubles.

In October and April, the costs of heating with electricity will be completely insignificant - 2-3 thousand rubles.

We summarize - the total costs of heating a well-insulated house with an area of \u200b\u200b100 square meters in the middle lane of Russia and in the Urals will be 50-60 thousand rubles for the entire heating season. And the practice of heating with electricity confirms this.

Of course, if you have or heating the house with a solid fuel boiler, then these calculations you can omit.

Cost of lighting in a private house

If you put in all lamps in your home energy-saving lamps with an average power of 13-15 watts, which is equivalent to an ordinary lamp in 75 watts, then your home lighting costs will be laid in quite reasonable limits.

In winter, the lighting works 10 hours a day, and in the summer period - 3-5 hours, excluding outdoor lighting. Of course, if you correctly mount outdoor lighting and provide it with lighting and movement sensors, then the external lighting will work no more than the internal.

So, you have a house of 100 sq.m., in which you have approximately 20 15 watt lamps. This is only 300 watts per hour. With the average lighting time at 7 o'clock (and in winter, and summer) - this is only 2 kilowatt per day or 60 kilowatt per month.

That is, the costs of lighting in 100 square meters will make not more than 200 rubles per month.

Cost of electricity in the kitchen

If you do not have a gas, then you will have to prepare food on electricity. Modern electric plates are highly effective, but they also consume from 5 to 7 kilowatt electricity per hour at full capacity.

Approximate costs of cooking with electricity will be from 300 to 500 rubles per month, regardless of the area of \u200b\u200byour home.

Other electricity costs in a private house

Circulation pump heating system, boiler automation, los compressors, televisions, satellite receiver, computers, washing machine, Chargers for phones - All these are electricity users in a private house. And they all demand kilowatt, although a little. About 200 to 300 rubles per month you will have to maintain these devices.

When buying or building a country cottage, the question of the heating of the building in the cold season arises. It is not always possible to connect to the gas distribution network or enjoy the blessing of the central heat supply. In this case, a solid fuel boiler for the heating of a private house is one of the most practical options. Due to the significant increase in electricity prices, the purchase of solid fuel for the heating system is more profitable.

Types of solid fuel boilers

Today, various heating equipment is presented on the market, which is based on the combustion of solid raw materials. Depending on the source used, the following types are distinguished:

• Coal. Coal briquettes, stone and brown coal, anthracite can be used as fuel. The equipment is available at a price and simply in operation. The undoubted advantage of the coal aggregate is the high efficiency.
• Pyrolysis. Boilers function on solid biological fuel. The raw material is subjected to a pyrolysis process, resulting in a high combustion temperature and, as a result, high efficiency (80-90%).
• Pellet. Such boilers belong to high-power equipment. They are suitable not only for the heating of a country house, but also for the implementation of a mini-boiler room. The energy carrier for such aggregates is special pellets from wood peat. With the right use of the CPD boiler reaches 90%.

Materials for equipment

Modern manufacturers for the manufacture of boilers use high-quality, heavy-duty materials - cast iron and steel. Each of them has their own advantages. Definitely determine which is better - it is impossible.

Cast iron, due to high resistance to external environmental impacts, has a long service life, about 30-40 years. But chemically aggressive substances resulting from the combustion of fuel, from the inside destroy the furnace. In order to maximize the service life of pig-iron equipment, it is necessary to competent design and installation of the boiler.

Steel boilers are also resistant to temperature drops and exposure to external factors. Equipment made of steel is durable and durable. But such aggregates are suitable for the arrangement of open heating systems in which there is no high pressure occurrence.

Solid fuel boilers for heating a private house in our online store are presented in a wide range. Among the presented models it is easy to choose and buy equipment corresponding to a specific case. We offer only affordable prices for all aggregates implemented by us.
