Gas cylinders filled with propane-butane have long become commonplace in the kitchens of country houses. But will it be a rational decision to heat a private house using liquefied gas? Before converting your home heating system to the consumption of liquefied petroleum gas (LPG), you need to clarify several issues for yourself. Among them, the most important ones are: what will be the consumption of liquefied gas for heating the house, and how real will the benefits be?
Heating with gas from cylinders
There are often reviews that heating with liquefied gas supposedly requires huge financial expenses. There is an opinion that the purchase of gas equipment, as well as installation and maintenance of the system, is accompanied by excessive costs. But this is not always true, and year after year, heating a private house with liquefied gas in cylinders is gaining new adherents among owners of dachas and cottages.
Advantages of LPG
- Possibility to arrange autonomous heating using liquefied gas at a distance from gas mains;
- Ease of transportation that does not require the construction of pipelines;
- Higher heat capacity of the propane-butane mixture compared to natural gas;
- Environmentally friendly fuel obtained during oil production and refining;
- Relatively low cost in the face of rising prices for other types of fuel.
Disadvantages of LPG
- The cost of gas delivery for heating private houses with liquefied gas in cylinders may increase when the household is located too far from the city;
- In frosty winter, when heating a private house with liquefied gas, the problem of freezing of the gas reducer arises;
- If you create a fuel reserve in a gas tank installed on your site, then during periods of snow drifts there may be difficulties with the refueling vehicle getting to the house;
- The design and installation of autonomous heating using liquefied gas is permitted only with the involvement of specialists from authorized organizations. And only the least critical elements of a liquefied gas heating system can be made with your own hands.
Features of heating with liquefied gas
The owner of a liquefied gas heating system is forced to monitor whether the fuel in the container connected to the boiler is running out. Some may consider this feature an inconvenience, but such a heating system can be autonomous and not depend on problems with the central gas supply. You just need to regularly replace gas cylinders or immediately pump a sufficient amount of gas into the underground storage.
Use of gas cylinders in heating
The option of heating a house with liquefied gas in 50-liter cylinders is ideally suited for country houses and small cottages. To avoid having to disconnect an empty cylinder every two days and connect a full one in its place, you can combine several cylinders into a battery at once. For this purpose, GOK fittings are used. If a homeowner installs liquefied gas heating with his own hands, he has the right to install a battery of no more than 3 cylinders without a project. A larger number of them will require a project.
Gas cylinders are installed not indoors, but in a metal cabinet on the outside of the house. In winter, there are often cases of reduced gas supply through the reducer due to the fact that the condensate contained in the cylinders partially freezes.
To prevent freezing of gearboxes at low temperatures, you can install a small electric heater in the cabinet with cylinders.
Gas holder for home heating
It is convenient to use cylinders when gas consumption is not too high, and their delivery service operates uninterruptedly. In other cases, it will be more rational to purchase and install a gas holder - a large underground tank for storing LPG, which will have to be filled with gas only 2-3 times a year. The volume of the gas holder can be from 3 to 10 cubic meters; it is selected in accordance with the power of the heating system.
An underground gas tank is allowed to be located no closer than 10 m from a residential building, and from the road side it must be accessible for a refueling vehicle.
Calculation of costs for the installation of autonomous gas heating
When comparing which types of heating systems will be the least expensive, you must first pay attention to the consumption of liquefied gas for heating. It is advisable to compare the upcoming costs with similar costs for other types of fuel and decide which option will be more profitable.
Initial costs for equipment and arrangement
The costs of purchasing equipment and installing an autonomous liquefied gas heating system in your home may vary slightly in different regions of residence. But in general, when compared with connecting to the main gas pipeline, the difference in cost will be insignificant. It will be more expensive only if you use not cylinders, but a gas holder with a volume of several cubic meters. Its cost will be more than 300,000 rubles.
Also, the cost of arranging premises for boilers using LPG is almost equal in cost compared to those using diesel fuel. As evidenced by reviews, heating with liquefied gas only requires higher initial costs when it serves as an alternative to solid fuel or electric heating. But during further operation, the funds invested in heating a private house with liquefied gas will gradually pay off due to the profitability of this type of fuel.
Gas costs for heating a private home
Just a few years ago, a propane-butane mixture was much more expensive than main gas (methane), but over time the price difference between them is decreasing. Therefore, relative indicators of the cost and consumption of liquefied gas for heating demonstrate the feasibility of using this energy carrier.
The simplest way to determine the real consumption of liquefied gas for heating a house is to correlate the mass of gas in one cylinder with the technological characteristics of the heating equipment. In this case, it is more convenient to calculate the consumption by weight, since the volume (in liters) depends on the density and percentage composition of the propane-butane mixture pumped into the cylinder.
A standard 50-liter cylinder can be filled with 35–40 liters of LPG, which in terms of weight gives an average of 22 kg of gas.
Let's look at a specific example to determine the required amount of liquefied gas in cylinders for heating a house with an area of 100 m²:
- To heat the specified area you will need (at maximum standards) 10 kW of heat energy;
- However, the boiler does not operate constantly at maximum mode, and its average load factor can be taken as 0.5. This means we need 5 kW;
- With a calorific value of liquefied gas of 46 mJ/kg, to produce 1 kW of heat energy, about 0.1 kg of LPG will be consumed per hour, and for 5 kW, 0.5 kg of LPG will be required;
- 12 kg, or almost half of the cylinder, will be consumed per day;
- The monthly consumption of liquefied gas for continuous heating of the house will be approximately 13–15 cylinders.
What will the consumption be if you do not use cylinders, but pump fuel into a gas tank? How often will you have to call a gas station to replenish the gas supply in the “five cubic meter” tank that is most common among consumers? Let's figure it out:
- Any of the containers for liquefied gas is not filled “to the neck”, but only 80–85%. Accordingly, a tank with a volume of 5 m³ will contain about 4250 liters or (in terms of weight) 2300 kg of gas;
- We have already determined that in our case, the liquefied gas heating system consumes 0.5 kg of fuel per hour;
- We divide the total mass of gas contained in the gas tank 2300 kg by 0.5 kg/hour, and we get 4600 hours - for such a time we have enough fuel reserve;
- Dividing 4600 hours by 24, we get a total of 190 days. That is, one refill of a gas tank with a volume of 5 m³ is enough to heat a 100 m² house for almost the entire heating season (in a temperate climate).
These are theoretical calculations, but in reality, fuel consumption can be significantly reduced. With the correct setting of combustion modes, a gas heating boiler for liquefied gas can consume 1.5–2 times less fuel, and the temperature in the house will be maintained at an acceptable level.
To reduce the amount of gas burned, use automation, which switches the boiler to moderate mode at night, reducing the temperature in the system by 7–9 degrees, thereby achieving a cost reduction of 30%.
Heating equipment for heating with liquefied gas
To heat a private house using liquefied gas, both heating boilers with a water circuit and gas convectors are used. But among all types of similar equipment, liquefied gas heating boilers still lead as the most productive. Reviews of liquefied gas heating using convectors are rarely positive.
Gas heating boilers for liquefied gas are almost no different in design from those that consume mains gas. The only difference is in the design of the burners, since the pressure of propane-butane coming from the cylinder is almost 2 times higher than natural methane. Accordingly, the jets in the burners also differ in internal diameter. There are also some differences in the devices for regulating the air supply.
The design differences are so insignificant that, if necessary, it is enough to just replace the burners in a boiler designed for methane, and you will not have to buy a new liquefied gas heating boiler.
Let's look at the differences between the main models of boilers for liquefied gas heating systems:
- Boiler type. Among the units for heating a private house with liquefied gas in cylinders, single-circuit and double-circuit boilers are distinguished. The former serve only for the heating system, and the latter, in addition, provide hot water. The combustion chamber in boilers is designed differently; it can be open or closed. Both large floor-standing models and compact wall-mounted ones are available;
- Efficiency. Judging by the reviews, heating with liquefied gas can become truly rational and economical if the gas boiler has an efficiency of at least 90-94%;
- Boiler power. It is considered one of the main parameters when heating a private house with liquefied gas. It is necessary to make sure that the specifications of the unit will allow it to develop sufficient power to provide the entire area of the home with heat, but at the same time avoiding excessive consumption of liquefied gas for heating;
- Manufacturer. While pipe routing in a liquefied gas heating system can be done with your own hands, a gas boiler should in no case be homemade. Moreover, it is advisable to give preference to well-established domestic or foreign manufacturers.
Liquefied gas boilers are prohibited from being installed in basements, since the propane-butane mixture is heavier than air. When leaked, such gas does not disappear, but accumulates at floor level, which can lead to an explosion.
Gas heating system maintenance
The heating system of a private house using liquefied gas requires periodic monitoring and maintenance. The trouble is if in the middle of winter the boiler suddenly stops functioning normally! Causes of malfunctions of gas heating boilers for liquefied gas
are mainly associated with a clogged burner or fuel filter. It is advisable to detect all faults in advance, and an experienced specialist should search for them.
The technician must check the condition of the liquefied gas heating boiler 1-2 times a year and carry out maintenance with the same regularity. The list of works boils down to inspecting the burners and combustion chamber, cleaning from soot and soot, checking the automation, and adjusting the equipment.
The video will demonstrate what a worthy alternative to natural gas can be liquefied petroleum gas (LPG).
In conclusion, we can add that many users are campaigning for heating with liquefied gas; their reviews indicate the effectiveness of the autonomous system. Even despite the hassle associated with periodically replacing gas cylinders.
Gas heating is rightly called one of the most economical options for creating a comfortable temperature in the house. To plan expenses for the heating season, it would be nice to know approximate fuel costs.
Let's try to calculate the gas consumption for heating a house of 150 m2.
Fuel consumption assessment
To determine fuel consumption, we need to know the following:
- Duration of the heating season;
- Boiler power;
- Fuel consumption by equipment per unit time.
Let's assume that our heating season lasts 6 months.
What boiler power is needed to heat a 150 square meter house? On average, 1 square of area will require 0.1 kW of energy. In our case, we will need a 15 kW boiler (150 × 0.1).
Next, we need to find out how much gas such equipment consumes per unit of time, for example, per hour. This indicator is indicated in the instructions, and for our calculations we are currently using the average option for a 15 kW device - 1.68 cubic meters per hour.
Since we will not heat it around the clock, we will assume that the boiler operates 10 hours a day. Thus, per day we will process 16.8 cubic meters of gas into heat. Our heating season has 180 days, during which 3,024 cubic meters of gas will be consumed.
This figure should be multiplied by the cost per cubic meter for your region, and you will get estimated heating costs. Knowing them, you will be able to plan your budget and consider the feasibility of taking measures to save gas consumption.
What if I use liquefied gas?
The calculation is exactly the same, only kilograms are used instead of cubic meters. The average gas consumption of a boiler using reduced fuel (provided that our power is the same 15 kW) is 1.29 kilograms per hour. Per day - 12.9 kg. For the season - 2,322 kg.
What is the weakness of these calculations?
Please note that this is an estimate. Some circumstances are not taken into account here:
- The intensity of the fire will vary throughout the season. At the end of autumn and beginning of spring, the boiler may not turn on at all. When calculating, we assume that the boiler operates evenly throughout the entire period. The intensity of use of the boiler is also influenced by non-climatic factors: the quality of radiators (heat transfer efficiency), the presence of additional heating (warm floors), etc.
- Boiler efficiency (that is, gas consumption to produce a given volume of thermal energy) is not a stable indicator. If the house is well insulated, the equipment is kept in order and the chimney is regularly cleaned, then the room will warm up with less gas consumption than in the opposite situation.
On the other hand, in the absence of thoughtful insulation, the heater will work hard to heat the rooms to the desired temperature. This results in increased fuel and financial consumption.
Calculating gas consumption for heating a house of 100 m2 in cubic meters is an elementary school task based on proportions. It is enough to know how much fuel is needed to heat a unit area of an individual house.
Two thermal power coefficients will also be useful: one for main gas, the second for a liquefied mixture of butane and propane.
Why choose gas
In the last century, firewood was chosen as an economically viable fuel. With the development of mechanics and technology, the palm passed to coal. The discovery of natural combustible gas deposits has replaced coal, and there are fewer harmful emissions into the atmosphere.
The era of the development of green energy and the exploitation of renewable energy sources in the form of solar radiation and wind has arrived. But not everywhere the number of windy days is sufficient to generate and accumulate electricity necessary to heat a water boiler. Solar panels are still expensive. A person adheres to a conservative and inexpensive method of heating his home - with natural gas.
Let's compare emissions from the combustion of coal and natural gas.
Pollutant | Emissions from combustion, maximum |
|
Hard coal, g/t | Natural gas, g/m3 |
|
% of working mass of fuel | ||
Carbon dioxide CO2 | ||
Nitrogen oxides in terms of NO 2 | ||
Sulfur oxides in terms of SO 2 | - | |
Benzopyrene | 0,014 | |
As can be seen from the table, the content of substances hazardous to human health in gas is lower than in coal. Therefore, natural blue fuel is used to heat homes.
General parameters influencing the volume of fuel burned
The amount of fuel for heating a home is calculated either in liters or in cubic meters. ---If gas is supplied to a residential building via a centralized gas supply system, then accounting is carried out in cubic meters.
When connecting a house to an autonomous heating system, natural liquefied gas is used in cylinders and records are kept in liters.
For the same area of the home, fuel consumption for heating depends on several parameters:
- year of construction;
- number of floors;
- construction materials;
- design features of window and door openings;
Walls, roof, doors and windows are sources of heat loss. No powerful heating boiler will save you if the doors and windows do not close tightly, if there are cracks in the wall seams and ceiling. When installing a gas boiler in a house, it is necessary to take measures to restore the thermal insulation.
Calculation of gas volume for home heating
Let's carry out calculations for the climatic conditions of the Southern Urals. According to the rules, the heating interval for housing is set from September 15 to May 15. The reasonableness of the norm is confirmed by the fact that in the Urals it still snows in the first half of May, and in the second half of September. The duration is 242 days. The consumer will regulate the start and end of heating independently.
Heat is supplied to living rooms 24 hours. In total, the gas will have to be burned for 5808 hours. This is the maximum required operating time for gas equipment.
Axiom of heating calculations: heating 10 square meters of housing requires 1 kilowatt of energy. Then the house considered in the example needs 10 kilowatts. In reality, this standard is half as much due to a sudden early and warm spring, or a long and hot autumn, or the winter frosts will not be the Ural cold, but the weak Crimean cold snap. Let’s agree that the energy consumption for heating one hundred square meters of living space will be 5 kilowatts.
Let's calculate the gas volume consumption per hour. Let be:
0.92 - maximum efficiency of the heating unit;
H - volume of gas consumption for heating a house of 100 m2 per m3;
T - power for heating 100 m2, kilowatt;
C - the lowest calorific value of main fuel is 10.175 kW/m3.
Then H = T / (C * 0.92) = 0.5341 m 3 / h.
Consequently, the gas consumption for heating a house of 100 m2 in cubic meters will be 3102 m3.
Autonomous heating with liquefied gas mixture
If natural gas is not supplied to the building via a pipeline, then the boiler is connected to a cylinder or gas holder with a propane-butane mixture. Liquefied gas is recorded in kilograms. Therefore, the value “C” from the calculation formula is equal to 12.8 kW/kg.
The weight of one liter of the mixture is 0.54 kg. Let's calculate the weight of the hourly volume of the mixture.
H = 5 / (12.8 * 0.92) = 0.4246 kg/h, liquefied mixture.
Now it remains to calculate 100 m2 in liters for heating a house.
Volume L = 0.4246 * 5808 = 2466 liters.
How many refilled cylinders will be needed for one heating season? One cylinder holds 42 liters of fuel. All you need is
2466 / 42 = 59 cylinders.
Price issue
In the Chelyabinsk region, the cost of 1 cubic meter of natural main gas is 6.15 rubles/m 3.
The liquefied mixture in cylinders, without delivery, depending on the area is 16.82 - 19.26 rubles per kilogram.
Monopolists only raise prices. It's time to reduce the burden on the consumer wallet. The insulation of windows and doors is discussed above. But other methods have been developed. The measures will add comfort to your home and reduce heating costs.
The amount of fuel for heating an individual home is reduced by any of three measures, or by the whole complex:
Modern gas heating boilers are operated for both types of fuel after the burner has been adjusted by a gas technician.
If the budget allows, then when using liquefied gas it is better to install not a pair of individual cylinders, but gas fittings for group installations with automatic control.
The formula given in the article is used to calculate gas fuel costs for a house of any size. Carefully apply the coefficients for main gas and for a liquefied mixture of propane and butane.
The owner of a private house, even at the construction stage of the building, is faced with the question of how and how the home will be heated. There are plenty of options. The boiler is the main element of the heating system. Various modifications of devices operate on coal, wood, natural or liquefied gas. Let's say it is more convenient for the owner of a private house to use liquefied gas. What is the consumption of liquefied gas for heating a house of 150-200 m2?
Liquefied gas means a symbiosis of ethylene, propane, butane and other chemical compounds. It releases more energy than other fuels. This is a scientifically established fact.
You can calculate the energy consumption for heating a house of 150-200 m2 using the simplest formula, based on which 1 kilowatt per hour is needed to heat 10 square meters of a building. It turns out that 10 square meters will require 24 kilowatts per day, and 200 square meters will require 480 kilowatts. This formula takes into account all the building’s “needs” for heat.
It is necessary to take into account not only the area of the building, but its cubic volume, which involves entering data such as the height of the walls.
If we talk about a standard building, where the height of the walls does not exceed 250 centimeters, then the same simple formula can be used.
It is applicable both if the house is used permanently and when it is used as a temporary home. This is what experienced builders advise.
If a house has a standard wall height of 2.5 meters, then gas consumption for heating is calculated using a simple formula - 10 square meters “consume” 1 kilowatt of energy
If the house is your fortress, and the “weather” inside is an important factor for you, then it is advisable to also include the thermal stability of the entire house and the temperature values outside the window when calculating the cost of heating a house of 150-200 m2. To do this you will have to turn to professionals. Is this option not suitable for you? Then we use a simple formula.
Important: the gas boiler does not operate 24 hours a day. Typically, the operating mode is as follows: the equipment works for 1 hour, rests for 1 hour. This means that, according to a simple formula, the energy consumption per day to heat a 200 m2 house will be 240 kW.
You can learn more about the operation of a gas boiler from the following video:
Let's assume that winter in the region where you live lasts approximately 200 days (October - end of March, beginning of April). Then during the season the building will consume 48 thousand kW. So far we are talking only about energy, and not about liquefied gas itself. It is very important to find out exactly the amount of “power” that the house needs for heating during the entire cold period. This data is necessary to calculate the consumption of liquefied gas for heating a house of 150-200 m2.
Costs of a gas boiler using liquefied gas: calculating the indicators
Over the entire heating season, a house with an area of 200 square meters will consume about 48 thousand kilowatts of thermal energy. Liquefied gas has its own ability to “create heat”. It shows the ratio of a unit of fuel to the energy released by it during combustion (combustion).
Scientists have calculated that the calorific value of one cubic meter of liquefied gas is equal to 6.55 kW of heat energy.
One liter of liquefied gas emits 6.55 kilowatts of energy when burned
To find out how much reduced gas is needed to heat a house of 200 square meters, we take the amount of energy that the building will consume during the entire cold period (48 thousand kilowatts) and divide it by the calorific value of this type of fuel (6.55 kW). This turns out to be approximately 7330 liters.
If we add another 10 percent to 7330 liters, we get 8063 liters. This will be the consumption of a gas boiler running on liquefied gas.
Nuances and subtleties
It is important to understand what the liquefied gas consumption will be for heating a house of 150-200 m2 in order to take care of how the fuel is stored. You can hold it:
- in cylinders. Their volume is small - from 10 to 50 liters. Regular replacement or refilling is required, which is not very convenient. In fact, approximately 35 liters will be needed per day for heating with liquefied gas;
- gas holders. This is a special storage (reservoir) for blue fuel. Can hold from 200 to 1000 liters depending on the dimensions. Such a structure must be built in accordance with safety requirements and standards. To refill the gas tank, you will need to call specialists. Attempts on your own may result in fires and explosions.
Gas holder - a container for storing liquefied gas for heating - can hold up to 1000 liters of “blue fuel”
As for the prices for such heating, they depend on the region where you live.
The cost of a liter of liquefied gas varies from 12 to 20 rubles. Based on the average value of 15 rubles, during the heating season you will spend approximately 121 thousand rubles on a building with an area of 200 square meters.
Any other type of fuel will be cheaper. For natural blue fuel - approximately 40 thousand rubles, for firewood and coal - about 60 thousand rubles per heating season.
How to reduce consumption?
It is possible to significantly, by a couple of tens of thousands of rubles, reduce the consumption of liquefied gas for heating a house of 150-200 m2. To do this, you will have to properly insulate the room (this is needed if a gas boiler is used in the building).
- insulate the foundation and roof, attic and basement. There you can lay a thin layer of mineral wool (this is the cheapest insulation);
- replace ordinary windows with plastic ones, which are considered more airtight;
- insulate the metal entrance door from the inside;
- believe and reduce;
- install a modern boiler. Experts recommend trusting companies such as: Bosch, Buderus, Protherm, Vaillant. The price of a new boiler is from 20 to 100 thousand rubles;
- replace old heating system pipes with new ones, check their tightness and connections;
- Instead of “ancient” batteries, install bimetallic, aluminum or steel radiators.
To minimize heat loss when heating with liquefied gas, replace old batteries with new radiators
Finally
Today, liquefied gas is one of the most expensive types of fuel. If there is no other option, then minimize heat losses at home to avoid unnecessary costs. Heating consumption can be calculated using the simplest formula. This will be enough to understand what amount to target.
10 square meters of building consume 1 kilowatt of energy per day. When burned, 1 liter of liquefied gas releases 6.55 kilowatts of energy. Be guided by these numbers when making calculations.
If a more complete and accurate calculation is required, it is advisable to turn to professionals. Although with a complete and simple calculation the numbers differ slightly, by a couple of thousand rubles.
It is likely that you can save on the services of specialists by not hiring them at all.
You will learn how to make the calculation in the following video:
Despite the general trend of rising prices for energy consumption, heating a home with natural gas is still considered the most efficient and cost-effective option. And all those who doubt and cannot decide on the optimality of such a heat source for their home can be advised to familiarize themselves with the approximate calculation of gas consumption for heating a house of 100 m².
- Q=100*50=5000 W or 5 kW;
- A=5/9.45*0.95=0.56 m3/h.
- Ac=0.56*24*30*6=2419.2 m³ - will be needed for the entire heating season.
- 1. A=5/12.5*0.95=0.42 m3/h;
- 2. Ac=0.42*24*30*6=1814.4 m3/h.

Basic calculation parameters
Gas heating is rightfully considered not only an economical, but also an environmentally friendly option. However, before purchasing equipment and installing it, it is necessary to calculate in advance the potential costs of blue fuel. Carrying out such a calculation is necessary in order not to make a mistake in choosing the power of the boiler and the consumables supplied with it, because the highest indicators in this matter do not always serve well during further operation.
And if a boiler that is too weak cannot boast of high performance, then a powerful installation with minimal loads tends to wear out very quickly and, as a result, fail ahead of schedule. In addition, boilers of increased power require greater consumption of resources, ultimately being more expensive to maintain, so there is no point in purchasing equipment for a room of 500 square meters if the issue of heating a house of 100 m² is on the agenda.
In order to correctly determine the potential costs of heating a residential premises, it is recommended to take into account certain factors and nuances. Usually it's about about such important parameters:
In order to determine the consumption of natural methane or propane-butane mixture for heating a house, it is necessary to take into account the level of heat losses that inevitably occur through walls, windows, roofing and floors. The calculation of this indicator is influenced the following factors:
To obtain the most accurate values, it is recommended to take into account not only the efficiency of the gas boiler, but also the performance of the entire heating system. In addition, the type of fuel used, which has different densities, should be taken into account.
Propane heating Gas consumption 2017 Buderus boiler
Not all owners have the opportunity to connect to the gas mains, but this is not at all a reason to refuse such an accessible, efficient to use and relatively safe energy resource. Today, for domestic purposes, it is common to use these types of gas:
There is no clear answer to the question of which type of blue fuel is the best, since both options have undoubted advantages and significant disadvantages.
For example, when heating a house with gas from the main networks, residents do not have to monitor the condition of the main equipment. At the same time, they completely depend on its serviceability, which is not so noticeable when installing gas tanks, which boast the highest level of autonomy.
The main disadvantage of a gas holder installation is its high cost, but in the absence of main gas pipes in the immediate vicinity, autonomous equipment becomes the only gas supply option. Nevertheless, such expenses are absolutely justified, because the gas mixture from the gas tank has a much higher calorie content, which is three times higher than the fuel from the main line.
Heating using liquefied gas (propane). Consumption, user experience.
When burning one cubic meter of propane-butane mixture, an average of about 28 kilowatts is generated, while when using network blue fuel that has undergone multi-stage filtration, this figure corresponds to only 9 kilowatts. This means that the average fuel consumption from gas tanks will be three times lower than the consumption of lower-calorie main gas.
Resource costs
You can find out how much gas will be used to heat a house with a certain area by performing basic calculations. In this case, it is recommended to carry out calculations taking into account the labeling of blue fuel and its main characteristics, among which density and specific heat should be highlighted. For example, one cubic meter of natural gas (labeled G20, G25) emits on average 9.2−9.5 kW of specific heat. Liquefied fuel (grade G30) produces about 12.5 kW of specific heat, having greater density and calorie content.
It is best to calculate the consumption of liquefied gas for heating a house of 100 m² using the formula A=Q/q*n, where the indicator Q is the product of the area of the house and the average energy consumption for one square meter, q is the specific heat corresponding to the selected labeling of blue fuel, and n - Efficiency of the equipment used in hundredths.
A conditional calculation of the required amount of energy resources is carried out taking into account normal indicators of external temperature, facade insulation and high performance of a gas boiler (efficiency = 0.95). Taking these factors into account, it is possible to calculate how many cubic meters of gas per heating season (As) will be required if its duration is a total of 6 months:
In the same way, you can calculate the potential gas consumption for any other square footage of a living space. For the above fuel markings and the efficiency of the heating installation will be relevant the following values:
| 80m2 | 1987.2m3 |
| 150m2 | 3628.8m3 |
| 200m2 | 4838.4m3 |
| 250m2 | 6004.8m3 |
| 300m2 | 7214.4m3 |
| 350m2 | 8424m3 |
| 400m2 | 10275m3 |
Heating a house is four times cheaper than a gas boiler.
In addition, when choosing a boiler for heating, you should take into account that the passport attached to it provides maximum performance values, so the efficiency of this installation may be lower than originally expected.
When calculating the consumption rate of liquefied gas, its density and specific heat should be taken into account. For example, to heat a house of 100 square meters you will need the following amount of propane-butane mixture:
When conducting a comparative analysis, it becomes obvious that with the main heating of an apartment or private house, more gas will be needed than with autonomous gas holder equipment.
At the same time, the cost of a mixture of propane and butane is much higher than methane, and even if we take into account that the ratio of consumption of raw material volumes will correspond to 1 to 3, then the total costs when using both types of heating will be approximately equal.
If the owners of the house live in a climate zone with harsh, long winters, and the cladding of their house is in poor condition or there are some other features that have a direct impact on heat loss, then gas consumption can be calculated using a special calculator. Such programs allow you to take into account the maximum amount of data and give more accurate results.
