We choose the most economical option for heating your home. How to save on heating a private country house Heating a house without extra costs
When starting the construction of their home, everyone asks the question: what energy source will they use to heat it? The choice is quite large, the amount of financial costs is very different. In general, there is something to think about and even get confused about. Therefore, in this article we will talk about the costs of heating a house using different types of fuel.
It’s good if you are lucky and there is gas on the site. And if it is not there, then what to do? You can use liquefied propane gas, bury the gas tank, not forgetting to periodically service it and fill it on time.
You can use an electric boiler, if, of course, there is enough electricity power limit, you can use a solid fuel, wood, or pallet boiler, or you can use a boiler with a diesel burner or, which is now gaining popularity, a heat pump. The main thing is to know the costs of heating your home.
You can estimate how much the equipment and its installation cost quite accurately by calling specialized offices, but not everyone will ask how much they will then pay monthly for energy consumption. Even if he thinks about it, he is unlikely to find the answers.
So now we’ll figure out how much it costs to heat a house, or more precisely, how much does 1 kW of heat cost, depending on the choice of energy source?
House heating costs with liquefied gas
Let's start talking about the cost of heating a house with a boiler room using liquefied gas. Let's leave everything out technical points by choosing a gas tank, a place on the site for its installation, periodic service, timely completion. Let's talk about the fuel itself.
Calorific value 1 liter of propane is 6.76 kW/h. This value is obtained by multiplying the calorific value of 1 kg of LPG 12.992 kW/h x density of LPG (0.52 kg/l).
Let us immediately clarify that all calculations take prices for the Moscow region, so if you live in another region, then they may differ slightly.
Then we perform the simplest calculation of home heating costs: cost of 1 liter of LPG/(calorific value of 1 liter of LPGxEfficiency)
Substituting all the data, we find that the cost of 1 kW/h of heat from a liquefied gas boiler is 2.65 rubles.
Heating costs with a diesel boiler room
- Calorific value 1kg diesel fuel– 11,860 kW/h;
- Density of diesel fuel – 0.86 kg/l;
- The calorific value of 1 liter of diesel fuel is 10.20 kW/h;
- The efficiency of the diesel boiler is 0.9.
- The efficiency of a diesel boiler is slightly lower, it is about 90%.
- The average cost of 1 liter of diesel fuel in Moscow is 36.8 rubles.
We substitute all the initial data into the formula:
Cost of 1 liter of diesel fuel/(calorific value of 1 liter of diesel fuel x efficiency)and we find that the cost of 1 kW/h of heat from diesel fuel is 4.01 rubles.
Boiler on pallets
Let's look at the costs of heating a house with a boiler room with a boiler on pallets. The calorific value of 1 kg pallet is 4.8 kW/h.
The efficiency of a pallet boiler is 0.87, that is, about 87%. The cost of 1 kg of light pallets for Moscow is approximately 7.80 rubles.
We calculate, accordingly, the cost of 1 kW/h of heat from a pallet boiler - 1.87 rubles.
Then let's look at a solid fuel boiler using birch wood. The calorific value of 1 kg of firewood is 4.2 kW/h.
The efficiency of a solid fuel boiler is 0.7. This figure of 70% is the lowest of all possible sources heat, which are discussed in the article.
The cost of 1 kg of firewood is approximately 3.33 rubles. We find that the cost of 1 kW/h of heat from a solid fuel boiler is 1.13 rubles.
Costs with an electric boiler
Now let's look at the capabilities of the electric boiler. In this case, you need to understand whether the allocated power limit is enough for you? Secondly, two-tariff electricity metering is already implemented almost everywhere.
Let's look at two options: single-tariff and two-tariff.
Single tariff option
In the single-tariff version, the cost of heating a house turns out that the cost of 1 kW/h of electricity in the Moscow region in 2017 is 4.04 rubles. In this case, the efficiency of an electric boiler is 1.
Accordingly, the cost of 1 kW/h of heat from an electric boiler is 4.04 rubles. In this case, savings can be achieved by using automation so as not to overheat the room needlessly.
Two-tariff option
In the two-tariff version, together with an electric boiler, it is installed storage capacity appropriate volume. In this case, the boiler mainly operates at night, at maximum power, at the night tariff.
It heats the room, and excess the heat is coming into the storage tank. Then, during the day, the room is heated using the heat accumulated at night at the night tariff.
Sometimes this heat is not enough and the boiler does not heat the house, sometimes this heat is produced in excess, so we take into account that heating occurs only at the night rate.
The cost of 1 kW/h of electricity in the Moscow region for 2017 (at night tariff) is 1.26 rubles.
The efficiency of an electric boiler is 1. In this case, the cost of 1 kW/h of heat from an electric boiler is 1.26 rubles.
That is, the cost will be a similar figure to the cost of electricity at the night tariff and will be equal to 1.26 rubles.
Costs with a heat pump
Now let's look at the cost of heating a house with. This is a new, complex topic. This is very promising direction, but only if the equipment costs less and there are more specialists. Technical part Let’s omit it and find out the cost of 1 kW.
In this case, we take into account the cost of 1 kW/h of electricity in the Moscow region for 2017 - 4.04 rubles. We take exactly this maximum tariff value.
Efficiency heat pump(conversion coefficient or thermal coefficient COP) – 3.61. This coefficient means that for every 1 kW of electricity consumed we will receive 3.61 kW of heat. Based on this, the cost of 1 kW/h of heat from a heat pump is 1.12 rubles.
Let's calculate the cost of 1 kW of heat from gas boiler. Calorific value of 1 cubic meter m of natural gas – 10.11 kW/h.
- The cost of 1 kW/h of electricity in the Moscow region is 4.04 rubles.
- The efficiency of a gas boiler is 0.92.
- The cost of 1 kW/h of heat from the boiler is natural gas– 0.43 rubles.
House heating cost table
So here's the pivot table. In addition to the cost of 1 kW, the estimated cost of equipment without installation has been added.

Let us explain what concerns the liquefied fuel boiler room: the cost of 1 kW, which we calculated, plus the cost of a gas boiler and plus the average cost of a gas holder without installation, of course.
Diesel boiler room: the cost of 1 kW is 4.01, the cost of a diesel boiler with a burner is 65,000 rubles, and the cost of a fuel tank is 20,000 rubles.
Boiler room on a pallet boiler: the average cost of a boiler on pallets is 180,000 rubles.
The average cost of a solid fuel boiler is 40,000 rubles.
The cost of an electric boiler is 30,000 rubles.
In the example with an electric boiler, we indicate the cost of the boiler equal to 30,000 rubles and plus the cost of the buffer tank equal to 90,000 rubles.
The cost of a heat pump with equipment will cost approximately 450,000 rubles.
As for the cost of heating a house if gas is available, at the lowest cost of kW/h, equal to 0.43, connecting gas is still quite expensive: that is, on average in Moscow it is about 350,000 rubles.
Perhaps in your region it will all be much cheaper.
Bottom line
The above figures clearly show that the last three options are the most interesting in home heating costs - a boiler room with an electric boiler with a buffer tank (night tariff) (2017); Heat pump; boiler room on natural gas.
Of course, you make a decision based on your preferences, priorities, and capabilities.
I hope you understand that not everything is determined only by the cost of equipment, but monthly payments for home heating costs must also be taken into account.
And finally:
We calculated the cost of 1 kW of thermal energy. And how many of these kW are needed for a home during the heating season?
Let's take, for example, a house with an area of 100 square meters. m. To heat it, approximately 10 kW/h of thermal energy is required:
10 kW x 12 hours (boiler operating time per day) x 214 days (duration of the heating period - for Moscow this period is 214 days) = 25,680 kW.
That is, we need to spend 25,680 kW during the heating season to heat a house with an area of 100 square meters. m.
If you multiply it with the cost of 1 kW, you get a completely different order of numbers. All this gives good motivation for thoughts on the right choice type of thermal energy source in order to intelligently approach home heating costs.
Energy prices are steadily rising, so everything large quantity Country residents are wondering how to heat their homes inexpensively and efficiently. Most often, homeowners are concerned about heating options for a private home and country house which boiler has the best high efficiency, which boiler to choose for the heating system, how to properly install the heating system, what types of heating without gas exist and which of them are the most economical.
FORUMHOUSE advises a different approach. First, we decide on the type of fuel, and then we select a heating system “for it.”
From our material you will learn:
- What are the costs of a heating system?
- What type of fuel can be called the most affordable;
- What means convenient system heating;
- Can heating with electricity be cheap?
- What can become the basis of an economical heating system.
What are the costs of a heating system?
Many factors influence how much a particular heating method will cost. Only after calculating all the costs (it is also necessary to take into account the increase in fuel prices in the long term) can you decide on the most cost-effective heating method. To do this, you need to consider:
- Fuel cost;
- The cost of its delivery;
- Price heating equipment;
- The cost of its installation;
- Costs of its operation;
- Average monthly air temperature in winter period time;
- Method of living in the house: “dacha” mode or permanent residence;
- Availability of utilities connected to the site (gas, necessary electric power);
- The degree of insulation and energy efficiency of the home.
Thinking about choosing a heating system and considering different variants heating in the house, first of all you need to answer the question: not “how”, but “with what” you will heat your home. It is the type of fuel, its cost and availability that determines the costs of the heating season.
Let's consider the following situation: main gas, as a more economically advantageous type of fuel, this moment no, or connecting it will be too expensive. What to do in this situation, what type of fuel to choose: firewood, liquefied gas, coal, pellets, fuel briquettes, electricity, even - there are a lot of options. Let's see which type of energy carrier is most preferable.
Conclusions:
- It would be correct to choose a heating system after proper calculation. This is the only way to achieve a balance between efficiency, economy and convenience;
- Vacation home it is necessary to insulate well, reduce all heat losses to a minimum, otherwise the lion's share of the energy will go to heating the “street”;
- Approximately, required power heating equipment is calculated using the formula: 1 kW of energy is required to heat 10 sq.m of house area;
- The efficiency of a heating system largely depends on the availability of a particular type of fuel;
- For getting maximum effect, must be combined different types heating systems and energy carriers. It cannot be said that if these conditions are met, we will get heating cheaper than gas, but we will be able to save significantly. combined heating system. And here -
During the winter period, it is most expensive for family budget is heating. Every year the cost of utilities, electricity, gas and water increases. That's why we decided
offer a number of tips on how you can save on heating your home.
Advice one. Install your own. Such a system, installed on your site, will allow you to fully or partially switch to an autonomous supply and independently meet your electricity and heat needs.
Tip two."Wrap up" in thermal insulation materials. By using high-quality materials for comprehensive insulation of walls, roofs, floors, ceilings, attics, basements and foundations, eliminating cold bridges in structures and insulating windows and doors, heat loss can be reduced by more than 50%, and overall energy consumption by 25%. The use of effective thermal protection will reduce annual energy from 250-350 to 100-150 kW/h per square meter living space.
Tip three. Install a heat pump. Such a unit uses low-temperature heat from an underground source and transfers it to the heating system of the house. Both soil and The groundwater, however, the temperature of this source should never fall below 1 C °. Anything warmer than this mark is suitable for the heat pump to receive its thermal energy, amplify it and make it work to heat the house. Thanks to this device, up to 75% of the energy needed to heat the house and water can be provided by nature.
Tip four. Install system air heating. It heats the air inside the duct and allows you to set your own temperature for each room in the house. 
Tip five. Install temperature programmers. These devices simultaneously monitor comfortable temperature in the house and reduce energy consumption by almost half. The principle of their operation is the rational consumption of energy at different periods of time: when you are at home, the heating maintains the desired temperature; when you leave, the programmable controller reduces the room temperature to the minimum comfortable.
Tip six. Paste heat reflective film on the windows. It's optical transparent material with a special multi-layer coating, which is installed on inner surface window. The film transmits 80% of visible light, and reflects about 90% of thermal radiation into the room, keeping the room warm in winter and cool in summer.
Advice seventh. Install. This will allow you to save heating costs in those rooms that you do not use and use heating systems more efficiently.
Eighth tip. Very simple. The means of heat conservation can be... ordinary ones. If you plant them around your house, they will help protect your home from cold winds and keep it warm. Trees should be planted at a distance from the walls that is at least twice the height of adult plants. It is clear that when winter is already coming full swing, it is impossible to use this advice. But with the onset of spring, planting trees around the house can be not only useful in terms of heat conservation during the winter, but also beneficial for health.
Significant savings at a low cost...The variety of heating systems presented on the Russian market would seem to provide the developer with significant freedom of choice. However, often the customer is tied hand and foot: gas is too far away, and going through the authorities takes a lot of time, nerves and money, and besides, we are going to Europe, which means European prices are not far off. Liquefied gas gives some freedom of maneuver, but is quite expensive. Diesel is associated with high operating costs plus additional inconveniences (odor, fuel delivery, boiler maintenance). Electricity is the most convenient and safe source of energy, but also the most expensive.
A heat pump can be a serious alternative to traditional heating systems. The source of energy for a heat pump is electricity, but since a heat pump does not produce heat, but only collects it, to obtain 1 kW of thermal energy it needs to spend only 200-250 W of electricity, therefore it is not enough to heat and hot water supply a house - an area of 100 m2 will require a heat pump with a power of only 2.5 kW.
Impressive, isn't it?
Complete heating system: heat pump and water heated floor
Warm floors and a heat pump are the most effective combination. Energy is not only “produced” economically, but also used economically! Water heated floor - low temperature system heating system, then thermal energy savings can reach up to 40-50%.
The ratio of consumed electricity to generated thermal energy by a heat pump (“heat pump efficiency”) largely depends on the heating system for which the heat pump supplies heat: the lower the design temperature of the coolant, the greater the efficiency of the pump. Due to technical limitations, the temperature supplied to the heating system from the heat pump does not exceed 55C, and the temperature return water should not exceed 50 degrees. With a radiator heating system, it is necessary to specifically calculate heating devices to use a heat pump system. When using a water heated floor heating system, no special calculations are required, these systems are created for each other!
Even with correct calculation radiator heating system, using a “warm floor” heating system will always give more efficient use energy accumulated in the environment!
By the way, the heat pump produces heat not only during the heating season; heat for the hot water supply system is generated all year round. And for the average country house cooking costs hot water are about 15-20 percent.
Heat pump operating on the “ground-water” principle extracts heat from the earth using probes or collectors. The brine transports heat to the heat pump. For small plots geothermal probes are optimal. The pipeline system is installed in the soil in vertical wells (1).
If the area is large, geothermal collectors are installed. Horizontal system pipes are laid below the freezing level of the soil (2).
Heat pump operating on the air-to-water principle extracts heat from the air. Fans move air through the evaporator, which extracts heat. The cooled air is discharged back (3).
Heat pump operating according to the “water-to-water” scheme uses groundwater as a coolant. They are pumped from the well and sent to the heat pump, where the heat is recovered. The cooled water is then directed to the absorption well (4).
Principle of operation
A heat pump heating system consists of a heat source, a heat pump, and heat distribution and storage units. In this case, heat transfer is carried out by low-temperature heating. The lower the water temperature in the supply pipeline, the work more efficiently the entire installation. The operation of a heat pump is based on technical principle refrigerator. But if the refrigerator removes heat from its internal space and transfers it to the environment through the grille located on the rear wall, the heat pump, on the contrary, takes energy from environment and transfers it through a heat exchanger to heating system. Air, earth or groundwater can be used as a heat source. The main advantage of air is its availability, while the earth's interior and groundwater are optimal heat accumulators with a relatively constant temperature throughout the year.
Operating principle of a heat pump
1. The cooled coolant, passing through the external pipeline, heats up by several degrees.
2. Inside the heat pump, the coolant, passing through a heat exchanger called the evaporator, transfers the heat collected from the environment to the internal circuit of the heat pump. The internal circuit of the heat pump is filled with refrigerant. The refrigerant, having a very low boiling point, passes through the evaporator and turns from liquid to gaseous. This occurs at low pressure and a temperature of -5 C.
3. From the evaporator, the refrigerant gas enters the compressor, where it is compressed to high pressure and high temperature.
4. Next, the hot gas enters the second heat exchanger, the condenser. In the condenser, heat exchanges between hot gas and coolant from the return pipeline of the home heating system. The refrigerant gives off its heat to the heating system, cools down and again turns into a liquid state, and the heated coolant of the heating system is supplied to the heating devices.
5. As the refrigerant passes through the pressure reducing valve.
It's simple!
The heat pump is ideal for new construction, since the heating system is immediately calculated taking into account further installation heat pump, in this case the heat pump will reveal all its capabilities. However, it can also be easily integrated into an existing heating system. This raises a legitimate question: how profitable is it?
To be fair, we note that equipping a boiler room with a heat pump is somewhat more expensive than installing equipment running on diesel or gas fuel, but low operating costs allow us to talk about payback within 1.5-2 years. In addition, the undeniable advantages of heat pumps are low installed capacity, low energy consumption, minimum maintenance, high comfort, presentable appearance, allowing installation in a residential area, as well as safety, which does not require any approvals or permits, make them one of the most promising heating installations.
How to choose - the right choice
When choosing a heat pump, it is necessary to take into account the energy status of the house. Regardless of the heating system used, it is important to ensure good thermal insulation building. The higher its indicators, the lower heating costs will be. This means that a heat pump of lower power will be required, which will reduce investment costs. And although in order to save energy it is advisable to use devices with low electricity consumption, when installing a heat pump, accurate calculation of the parameters is important, since choosing a unit with excessive or, on the contrary, insufficient power can lead to its inefficient operation. In addition, the operation of individual system components must be clearly coordinated.
Cooling work
Few people know that a heat pump can also work for cooling. For this purpose, two technologies have been developed: passive and active. Passive (natural) cooling takes advantage of the fact that groundwater and the earth's interior are cooler in summer than living spaces, allowing buildings to be directly cooled. Active cooling is achieved through air conditioning. A reversible heat pump allows you to control the direction of refrigerant flow. Heat from the room is transferred to the refrigerant and then released into the environment through a heat exchanger.
Manufacturers provide technical support during the selection, design and commissioning of a heat pump, including obtaining the necessary permits.
Heat pump in terms
· Regenerative energy - this is the heat of the Earth, the energy of the Sun, biomass, river winds and tides, capable of constantly being renewed or increasing in volume and therefore, by human standards, considered inexhaustible.
· Heat pump installation consists of a heat pump and equipment for access to the heat source, which is supplied separately for ground-to-water and water-to-water pumps. In contrast, for air-to-water pumps, the external communications for the heat source are already built into the unit.
· Annual output value (heat pump efficiency indicator) - this is the amount of heat obtained per year using a heat pump in relation to the cost of electricity.
· If, for example, it is equal to three, this means that the resulting thermal energy three times higher than the consumed electric power.
· Refrigerant- the working substance circulating in the heat pump. At the same time, its state of aggregation constantly changes from liquid to gaseous. Evaporation causes the absorption of energy, and the return to the liquid state causes its release.
· Monovalent mode of operation provides for the use of only one source of thermal energy, with the help of which the heating system can independently provide all heat needs. As a rule, they are used as monovalent
· pumps such as "ground-water" and "water-water". Since the temperature of the earth's interior and groundwater is practically independent of the ambient temperature, even at low sub-zero temperatures the heat source supplies enough energy to heat the house.
· Bivalent mode of operation provides for the presence of two heat sources in the heating system. The heat pump, driven by an electric motor, is combined with another heat generator powered by solid, liquid or gaseous fuel, which supports the heating system when too low temperatures environment.
· Monoenergetic mode of operation - a special form of bivalent regime. In this case, the additional heat generator is not a gas or liquid fuel boiler, but exclusively an electric heating device. Additional electric heating provides support for the heat pump during the coldest days of the year.
· Geothermal probes are placed in vertical columnar wells with a depth of 50 to 100 m.
· Supply and absorption wells designed to produce heat through a water-to-water heat pump. From the supply well, water is directed to the heat pump using a water pump. After thermal energy extraction groundwater through the absorption well it returns to the natural circulation.
DIY installation of heat pumps:
Vertical "ground-water"
1. Using a drilling rig, a well is made with a diameter of 20 cm and a depth of 50 to 100 m
2. A geothermal probe is placed inside a vertical column-shaped well
3. The depth and number of wells depend on energy needs and the geology of the area
Horizontal ground-water pumps
1. By using construction equipment near the house they dig a trench about 1.5 m deep
2. The horizontal pipe system is laid below the ground freezing level
3. The coolant is supplied through a special pipeline to the basement of the house
"Water-water"
1. The water collector is assembled from ordinary HDPE pipes filled with coolant
2. After which the resulting structure is carefully transferred to the shore of the reservoir.
3. Then immersed in water and carefully transported to the middle of the pond
"Air-water»
1. Installation of an air-to-air heat pump does not require excavation or drilling work
2. Typically, a geothermal pump of this type is installed 2-20 meters from a residential building
3. To install the heat pump on the site, choose a well-ventilated place
If the heating bills for your home exceed the average monthly Moscow salary and you are satisfied with all this, then you don’t have to read further - continue to heat your stove with thick wads of paper money.
If you are wondering how much you will pay and how to reduce the heating costs of your future home, then you are here just in time - this article is for you!
First, about the banal - a few myths about what you know or don’t know about:
Myth 1. Gas is cheap here, so I have nothing to think about
Well, almost the perfect phrase for the happy owners of yellow gas pipe- their life is really good! True, these people forget to count how much they paid the gas workers for the project and its approval, for supplying the pipe and its insertion, and God knows what else - count and divide. But it was worth it, because after that came Happiness!
Everything is fine, but there is a nuance - our government annually plans to raise gas tariffs for the population and in the very near future we will pay at the average European tariffs, and this is “more likely not a ruble, but more than a euro.” Think about it, the meager Russian pension is just around the corner.
Myth 2. I will make thick walls and install plastic windows
Well, this is generally a classic: a meter-long brick wall or 240 mm laminated veneer lumber - Africa is resting! We take the maximum thickness, install the walls “forever” and forget about heat loss forever - a perfectly working formula. In the window openings we make sure to install the most modern windows, three- or, what’s more, five-chamber! Sealed double-glazed window with selective glass, filled with argon, elite-wooden or seven-chamber plastic profile with a slot for ventilation - that's it, the heat won't go away, it will stay here. Great, your warm fur coat is ready!
Just great, though, again one nuance - let’s leave the cost of thick walls and windows, that’s not about that now - you traditionally forgot about the thickness of the roof insulation, the cold floor and the completely idiotic metal door. All these components of the frame of your home are no less important for heat conservation than walls and windows - the roof must have insulation of at least 400 mm, the floor simply must be “warm”, and Entrance door must be insulated, and even with several sealing contours.
Myth 3. I will install the biggest and hottest batteries.
Another typical opinion about heating a house with super radiators. Even if you take into account the current SNIPs and correctly position the radiators under the windows, you will not receive any guarantee that you will be warm. True, it’s quite possible that you will be hot, but your feet will be cold. The reason is simple - you are not warming yourself, but the place near the radiator, i.e. a local patch of space near the battery and that’s it!
The heated air rises, somewhere at the level of the torso and face you begin to feel warm, but your legs remain almost icy - after all, you simply forgot about them! The cure for this is quite simple - throw away the batteries. NO to batteries, YES warm floor. Water or electric - it's up to you. As a result, you get a uniformly heated floor surface, the heat from which you will feel with your whole body, without exception, and energy costs will be significantly reduced.
Further, at some point in time you become hot and then the quintessence of the process comes, and it’s simply banal stupidity - you open the window! For what? Well, to ventilate, to let off steam, to breathe fresh air to change the burnt-inhaled stale air to clean and fresh!
The moment you opened the window, you immediately crossed out all the costs for gas supply, for the thickness of the walls, for expensive windows, for heated floors - that precious heat that cost you a lot of money you simply...threw out the window!
Doesn't it smell like idiocy? Fully! This disease is treated very simply - you simply did not think about ventilation. Or rather, you certainly thought about it, but traditionally, in Russian - you were told that in your house there will be natural ventilation in the form of a hole in kitchen wall. Cheap and cheerful. Well, of course, ventilation, how could it be otherwise. But natural ventilation is not at all the kind of ventilation that should be in your home!
The essence of the process and the most important thing
When you sleep, you release 400 ml of moisture per night, when you wash, you get 10 liters of moisture in the form of evaporation, when you cook, you have 5 liters of moisture in the form of steam. Multiply this by the number of people in your home. This moisture will never be removed naturally, never! It will turn into condensation on the windows, fungus will feed on it, and mold will multiply in it. You will begin to get sick, and your house will begin to collapse.
For healthy and comfortable indoor air, it is necessary to replace used air with fresh air; all air in the house must be renewed every hour. This indicator is achieved only when using forced ventilation which will provide an influx of fresh air and an outflow of exhaust air.
In order to reduce the cost of heating a house, fresh air needs to enter the room already warm and comfortable, i.e. heated to a comfortable state. In a properly insulated, sealed house, this will be enough to keep the temperature inside the room constant, the one we need. If we do not open windows and doors, then the heat does not go anywhere, but remains in the house. Heating costs are reduced by up to 80%, so you save 4/5 of today's costs!
This result can be obtained by installing the system supply and exhaust ventilation with recovery. Great thing! The ventilation unit takes air from the street, purifies it, heats it with exhaust air leaving the house, and delivers fresh warm air to all rooms of the house. At the same time, she determines required quantity exhaust air, collects it and removes it outside, simultaneously heating the incoming air with this flow cold air from the street. Brilliant!
As a result of this process, you receive clean, fresh air, and dirty air is completely removed from the house. wet air. At the same time, the temperature in the house remains unchanged, and your body does not experience drafts, heat and cold. There is no need to heat anything additionally, because the windows do not open and the temperature does not drop. There comes a harmony that does not exist. Real health, sound sleep and longevity come.
Professional installation of a supply and exhaust ventilation system with recovery will provide your home with fresh air, which will extend your life by 20 years, save your home from destruction and save money on its heating. If your house is at the approval stage, we will design such ventilation and install it. If your house has already been built, then it doesn’t matter, we’ll figure it out and help you.
Make your life and the life of your home healthy!
Attention! We offer the best ready-made solution for your home - installation of a system that combines heating, ventilation and air cooling. As a result, in modern house, sufficiently sealed and insulated, you can successfully live year-round, without water heating or gas.
At the same time, the entire system will consume energy of only 1.5 kW/h - a fantastic result! For example, for a properly insulated stone house with an area of 180 sq.m., energy costs for heating it will not exceed 10,500 kW/year, which in monetary terms will amount to only 2,500-4,000 rubles/month for its heating in the winter.
Interesting Facts: - For the first time, the theory of natural air movement in channels and pipes was created by M.V. Lomonosov; from the beginning of these studies, the era of ventilation began throughout the world. - The first ventilation systems were used on ships to dry out rooms.- The first prototypes of modern
