Selecting the ideal heating solution is crucial for keeping your house toasty and comfortable throughout the colder months. Liquid gas becomes a practical choice for a lot of homeowners, especially when it comes to heating larger areas like a 200 square meter house. This post will go into great detail about the ins and outs of heating a space of this size with liquefied gas, including its consumption dynamics and factors to take into account.
Liquefied petroleum gas (LPG) is a widely preferred option for heating owing to its effectiveness and ease of use. It is an adaptable fuel that can run space heaters, boilers, and furnaces, among other heating systems. As an alternative to natural gas, which needs to be connected to a municipal supply, LPG is usually kept in tanks on the property, providing homes in places without mains gas access some flexibility.
Knowing how much LPG to use to heat a 200 square meter home is essential for efficiency and budgeting. The amount of gas required varies depending on the climate, insulation, and heating system efficiency. Larger homes typically require more energy to heat, but current heating technologies and adequate insulation can reduce usage.
Evaluating your home’s insulation is crucial before using liquefied gas for heating. Maintaining heat retention and cutting down on energy waste require proper insulation. The amount of heat required and overall comfort can be greatly impacted by insulation measures like double-glazed windows, wall and loft insulation, and draft sealing. Upgrades to insulation can result in increased comfort and long-term energy savings.

How to reduce gas consumption
A well-known rule states that less fuel is used to heat the streets the better insulated a home is. Therefore, high-quality thermal insulation of the house, including the roof/attic, floors, walls, windows, and hermetic sealing circuit on the doors, should be completed before beginning the installation of the heating system.
The heating system itself allows you to save fuel as well. You’ll get a more efficient heating if you use warm floors instead of batteries because convection heat spreads upward from the bottom, so the lower the heating device, the better.
Furthermore, the average temperature of the radiators is ninety, and the floors are regulated to fifty degrees. The floors are obviously more cost-effective.
Lastly, you can reduce gas consumption by varying the heating over time. Warming the house actively when it’s empty makes no sense. Sustaining a low temperature above freezing is sufficient to prevent pipe freezing.
With the help of modern boiler room automation (types of automation for gas heating boilers), you can operate from a distance. Before you leave for your house, you can instruct a mobile provider to alter the regime (what is GSM modules for heating boilers). A comfortable temperature at night is slightly colder than during the day, and t.D.
How to calculate the consumption of main gas
The power of the equipment (which determines how much gas is used in the gas boilers for heating) affects how much gas is used to heat a private home. When selecting a boiler, power is calculated. Start with the heated area’s size. Keep track of the lowest average annual temperature on the street and count for each room separately.

The resultant figure, t.To, is roughly divided in half to calculate the energy consumption. The season’s temperature swings from a severe negative to a positive, and so does the amount of gas used.
The ratio of kilowatts per ten squares of the heated area is the starting point for power calculations. We take half of this value, or 50 watts per meter per hour, based on the information above. 5, 000 watts per 100 meters.
The formula a = q / q * b is used to calculate the fuel, where:
- A – the desired amount of gas, a cubic meter per hour;
- Q – the power required for heating (in our case 5 kilowatts);
- Q – minimum specific heat (depends on the brand of gas) in kilowatts. For G20 – 34.02 MJ per cube = 9.45 kilowatts;
- In – efficiency of our boiler. Suppose 95 %. The required number is 0.95.
When we enter the numbers into the formula, we obtain 0.557 cubic meters per hour for 100 m^2. As a result, 0.836 cubic meters of gas will be used to heat a 150 m 2 (7.5 kW) home, 1.114 cubic meters will be used to heat a 200 m 2 (10 kW) home, etc. The received figure must then be multiplied by 24 to obtain the average daily flow and by 30 to obtain the average monthly flow.
Liquefied gas calculation
The aforementioned formula works with different kinds of fuel. liquefied gas in cylinders for a gas boiler, among other things. Naturally, his heat-intensive ability is different. This number, 46 MJ per kilogram, or 12.8 kilowatts per kilogram, is accepted. Assume a boiler with a 92% efficiency. When we change the values in the formula, the result is 0.42 kg/h.
After being converted to liters, liquefied gas is measured in kilograms. Divide the result of the formula by 0.54 (the weight of one liter of gas) to find the amount of gas needed to heat a 100 m 2 house from a gas tank.

Increase even more by multiplying by 24 and 30 days. We multiply the average monthly amount by the number of months to get the fuel for the entire season.
The monthly average consumption, roughly:
- liquefied gas consumption for heating house 100 m 2 – about 561 liters;
- liquefied gas consumption for heating a house 150 m 2 – approximately 841.5;
- 200 squares – 1122 liters;
- 250 – 1402.5 and T.D.
About 42 liters are contained in a standard cylinder. We determine the number of cylinders by dividing the gas needed for the season by 42. The quantity required for heating for the full season is then obtained by multiplying by the cylinder’s cost.

Calculation of gas consumption for heating a house
It’s critical to properly design the heating system to maintain a comfortable microclimate inside the house regardless of the outside weather. At this point, the boiler equipment is selected, and depending on the size of the house, the gas consumption for heating is 100 m 2 or another area.
The consumption is normative and real
The thermal calculation of the premises is done for extreme conditions, meaning the coldest five days of the winter, in accordance with the standards. When a specific climate’s long frosts occur, the boiler unit should be powerful enough to compensate for the house’s heat losses.
Thus, we find ourselves in the following circumstance:
- The power of the boiler is designed for the maximum load;
- boiler equipment is selected with a small margin of power;
- When selecting the power of the unit, gas consumption for cooking is taken into account, the use of other equipment operating on this fuel.
As a result, figuring out gas fuel consumption using the boiler unit’s rated power is absurd. In actuality, the country’s main heating season lasts roughly seven months, during which time the temperature varies significantly.
Take note! As per the above, the estimated value of the boiler’s passport power should be divided into two instead of using it to determine the average gas consumption for heating.
For instance. Utilizing condensed computations of the coolant flow rate, the standard thermal power value of 1 kW per 10 m 2 for a private residence is applied. This indicates that the boiler house’s estimated power for the 100 m 2 house will be 10 kW. As a result, 10/2 = 5 (kW) is the heat power indicator (q) that we need to compute the average fuel consumption.
Heating with main gas
The formula below is used to determine the amount of gas fuel consumed:
V is equal to q / (hi × ηi). Where:
- V (m 3 /h) – the volume of gas, which is required to be used to obtain a certain amount of thermal energy;
- Q (kW) – estimated thermal power that allows maintaining a comfortable temperature in the house;
- Hi (kWh/m 3) – an indicator of the lower specific heat of gas combustion, a standard tabular value (details below);
- ηi (%) – efficiency of the boiler Unit, an indicator, how effectively the gas boiler uses the generated thermal energy to heat the coolant.
The specific heat of gas combustion will be discussed. While G25 gas can also be utilized; details can be obtained from a local gas supply company, GAL G20 gas is primarily utilized in the primary networks. The increased nitrogen content in the G25 gas lowers its energy potential.
Natural gas type
Hello (lower combustion specific heat)
HS stands for the maximum specific heat of combustion.
9.02 kWh/m 3= 32.49 MJ/m 3
The table also includes the indicator HS, which is used to calculate fuel consumption for condensation boilers, in addition to the indicator Hi, which is necessary for calculations. Because the steam additionally selects around 10% of the thermal energy during the condensation process, this new generation of equipment is more efficient.
Take note! The formula must be changed to use kWh/m 3 instead of Hi.
The boiler’s efficiency (ηi) as stated on the product passport. Use a smaller coefficient for calculations if the document displays two indicators (for the highest and lower heat of combustion of gas fuel), as this more accurately represents the boiler’s actual capabilities.
For instance. We figure out how much the 100 m 2 house uses on average for the G20 main gas. In parallel, we will work with the assumptions that the house is insulated, that its estimated thermal capacity is 9.6 kW, and that its boiler unit’s efficiency is 0.92%.
Since the computed thermal power must be divided by two, as we already know, Q = 9.6/2 = 4.8 kW.
Calculating v, we get: 4.8 / (9.45 × 0.92) ≈ 0.56 m 3 / hour.
Determine the G20’s fuel consumption:
- per day 0.56 × 24 = 13.44 m 3;
- per month (on average) 13.44 × 30.5 = 409.92 m 3;
- During the heating season (7 months) 409.92 × 7 = 2869.44 m 3 .
The annual financial costs of heating can be computed by multiplying the price of one m3 of the primary gas available in your area.
150 m 2 of gas should be used to heat a house. The boiler efficiency is 0.92 if the G25 trunk gas serves as the fuel. The calculation was performed using a standard indicator of 1 kW per 10 m 2. Q = 15/5 = 7.5 kW, t.e.
V is equal to 7.5 / (8.13 × 0.92), or 1.002 m³/h.
Calculate the yearly consumption by rounding to the nearest m 3 /h: 1 × 24 × 30.5 × 7 = 5124 m 3.
This calculation method aids in obtaining an average value; on warm days, fuel consumption decreases in comparison to the average, and on frosty days, it increases.
Liquefied gas
The amount of liquefied gas used to heat the home is determined so that:
- understand the level of financial costs for the acquisition of fuel;
- Determine the optimal size of the gas tank or calculate the number of gas cylinders, develop a suitable schedule for their delivery.
The liquefied gas volume is expressed in liters, but the computations follow the same methodology as when the primary gas is used.
Propane-butane mixture known as liquefied hydrocarbon fuel G30 is primarily utilized in self-sufficient gasification systems. It possesses the following properties:
- fuel density 0.524 kg/l;
- Specific combustion heat of 45.2 MJ/kg = 23.68 mJ/l = 6.58 kW/l.
Important! Fuel with varying percentages of butan and propane (summer and winter) is used to fill the gas tank, so be careful when selecting liquefied gas and be aware of its properties when performing calculations.
The formula V = Q / (Hi × ηI), which we are already familiar with, is used to determine the volume of liquefied fuel required to heat a 200 m 2 house.
We will proceed by assuming that the estimated consumption, Q = 20/2 = 10 kW, is in line with the normative (1 kW per 10 m 2). The efficiency of the boiler is 0.92%.
V is equal to 10 / (6.58 × 0.92) = 1.65 l/h.
Consequently, the approximate yearly consumption volume will be 1.65 × 24 × 30.5 × 7 = 8454.6 liters.
By adding the fuel consumption to a gas stove and t.D. to the resultant value, you can choose the size of the gas tank and whether to refuel it once or twice a year.
In the event that the gas is delivered in cylinders, we can figure out how much is needed for heating. The cylinder has a total capacity of 50 liters, but since the fuel is not fully seasoned, there are only about 42 liters of liquefied fuel inside.
Boundaries for a 200 m 2 house during the heating season (7 months) are 8454.6 / 42 = 201,3.
You can therefore easily determine the average gas consumption for heating by changing the values in the formula to reflect the parameters of your home, the fuel’s properties, and the boiler unit.
How to save?
The following can lower the cost of keeping the home’s microclimate comfortable:
- additional insulation of all structures, installation of windows with double -glazed windows and door structures without cold bridges;
- installation of high-quality supply and exhaust ventilation (incorrectly executed system can cause increased heat loss);
- using alternative energy sources – solar panels and t.D.
The benefits of automation and a collector heating system, which help to maintain the ideal temperature in every room, should be discussed separately. This enables you to lower the heating of the coolant that is supplied to the radiators or a warm floor system in unused rooms, as well as the load on the boiler and the fuel consumption when warming on the street.
A sheet of thin foam insulator with an exterior foil surface can be glued to the wall behind each heating device if the house has a standard radiator system. Heat is effectively reflected by such a screen, keeping it from escaping through the street wall.
Lowering energy expenses can be achieved by implementing a series of actions targeted at improving the home’s heat efficiency.
How to avoid heat loss
The total area of heated rooms and the heat loss coefficient determine how much fuel is needed to heat the entire house. Any building loses heat through its walls, ceiling, lower floor floor, windows, and doorways.
Accordingly, the following variables affect the amount of heat loss:
- climate features;
- wind roses and the location of the house relative to the cardinal points;
- characteristics of the materials from which building structures and roof were erected;
- the presence of a basement/basement;
- the quality of floor insulation, wall structures, attic overlap and roof;
- the amount and tightness of the door and window structures.
By calculating the house’s thermal parameters, you can select boiler equipment with the best power specifications. To calculate the precise amount of heat required, the computation is carried out independently for every heated room. The heat loss coefficient, for instance, is higher in rooms with two windows, corners, etc. D.
Take note: The boiler’s capacity is chosen with a margin of error around the estimated values that were obtained relatively. If the boiler unit operates at its maximum frequently, it will wear out and fail sooner. At the same time, an overabundance of power results in higher fuel consumption and higher boiler purchase costs.
Calculation of gas consumption for heating a house 150 m2
It is crucial to ascertain the projected gas consumption for heating a 150 m2 house or any other area before setting up a heating system and selecting an energy provider. In fact, there has been a discernible trend in recent years for natural gas prices to rise; the most recent increase, which came into effect on July 1, 2016, was by roughly 8.5%. As a result, the cost of heating in cottages and apartments with separate heating sources that used blue fuel directly increased. For this reason, homeowners and developers who choose a gas boiler exclusively should estimate their heating expenses ahead of time.
Initial data for calculations
You must ascertain the following parameters in order to carry out the initial calculation:
- heat of combustion (calorie content) of natural gas supplied in your area;
- thermal load on the heating system;
- The efficiency of the boiler, which is planned to be installed in the house or apartment.
The value of the lower heat of the primary gas’s combustion determines the fuel’s calorie content.
It is theoretically possible to release 9.2 kW of thermal energy by burning 1 m³ of blue fuel. In actuality, this value varies—usually in a minor way. Its heat-grown ability can drop to 7.5-8 kW/m³ because some dishonest suppliers dilute the gas with air due to the same price increase.
If the management company’s calorie content is unknown, use the following figure with a margin of error in the calculation to estimate the amount of gas needed to heat the house: 8 kW/m³. A coefficient of 1.163 can be used to convert a specific heat of combustion measurement expressed in kcal/h, which is another unit of measurement, into watts.
The thermal load on the heating system, which is derived from heat loss through the building’s structures and losses for warming the ventilation air, is another crucial indicator that has a direct impact on fuel consumption. If there isn’t another exit, you can still calculate the load using enlarged methods, but the best course of action is to perform or order an accurate calculation of all heat loss:
- If the height of the ceilings does not exceed 3 m, then heat consumption 0.1 kW per 1 m² of heated area of the building is accepted. Thus, for a house of 100 m2 you need about 10 kW of heat, 150 m2 – 15 kW and 200 m2 – 20 kW of thermal energy.
- Put 1 m³ of the volume of the heated room 40-45 watts of heat. The load is determined by the multiplication of this value by the volume of all heated rooms.
Its technical passport indicates the heat generator’s efficiency, which influences the fuel combustion efficiency. If you haven’t purchased the unit yet, you can choose from the following list to determine the efficiency of different types of gas boilers:
- gas convectors – 86%;
- boilers with an open combustion chamber – 88%;
- heat generators with a closed camera – 92%;
- Condensation boilers – 96%.
Fulfillment of calculations
The following formula is used to estimate gas consumption for heating in an initial calculation:
Q / (q x efficiency / 100) equals V.
- Q – the calorie content of fuel, by default, 8 kW/m³ are taken;
- V is the desired maintenance consumption, m³/h;
- Efficiency – the effectiveness of fuel combustion with a heat source, is expressed in %;
- Q – the load on the heating of a private house, kW.
The computation of gas consumption in a 150 m² small cottage with a 15 kW heating load is one example. It is anticipated that a heating unit with a closed combustion chamber (efficiency of 92%) will be used for the heating task. In the coldest hour, the following is the theoretical fuel consumption in one hour:
2.04 m³/h = 15 / (8 x 92 /100).
The heat generator will use the maximum amount of natural gas on the coldest days during the day, which is 2.04 x 24 = 48.96 m³ (rounded to 49 cubic meters). However, depending on the area of residence, the temperature can vary by 30 to 40 °C during the heating season. As a result, the average daily gas consumption will be released at a lower rate, approximately 25 cubic meters.
Then, a 150 m² house in central Russia heated by a turbocharged boiler uses, on average, 25 x 30 = 750 m³ of fuel. The calculation of consumption for other sizes of cottages is done in the same manner. You can still take steps to reduce consumption during the construction phase by concentrating on preliminary calculations. These steps include insulation, selecting more energy-efficient equipment, and using automated regulation systems.
