Gas consumption for heating the house 100 m2 in cubic meters

Calculation of gas consumption for heating the house 100 m2 in cubic meters - the task of primary school in proportion. It is enough to know how much fuel you need to heat a unit of individual house area.

Two additional thermal power factors are also useful: one for the main gas, the second for the liquefied mixture of butane and propane.

Why choose gas

In the last century, fuel was chosen economically as a fuel. With the development of mechanics and technology, the palm tree has gone to the fossil fuels. The discovery of deposits of natural fuel gas pushed coal, harmful emissions into the atmosphere became less.

The era of green energy development and exploitation of renewable energy sources in the form of solar radiation and wind has come. But not everywhere the number of windy days is enough to generate and store electricity needed to warm up the water boiler. Solar panels are expensive. A person adheres to a conservative and inexpensive way of heating a home - natural gas.

Let's compare the emissions from the combustion of coal and natural gas.

As can be seen from the table, the content of hazardous substances for human health is lower in gas than in coal. Therefore, natural blue fuel is used to heat the housing.

General parameters of influence on the volume of combustible fuel

The amount of fuel for heating the housing is either in liters, or in cubic meters. If the gas is supplied to a residential building through a centralized gas supply system, the account is maintained in cubic meters.

When connecting the house to an autonomous heating system, natural liquefied gas in cylinders is used and the account is taken in liters.

With the same housing area, fuel consumption for heating depends on several parameters:

  • Year of erection;
  • Number of floors;
  • Construction materials;
  • Structural features of window and door openings;
  • Type of heating unit.


The 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 the ceiling. When installing a gas boiler in the house, it is necessary to carry out measures to restore thermal insulation.

Calculation of the volume of gas for heating the housing

We will calculate for the climatic conditions of the Southern Urals. According to the rules, the heating interval is fixed from September 15 to May 15. The reasonableness of the norm is confirmed by the fact - in the Urals in the first half of May still, and in the second half of September the snow falls already. The duration of the heating period is 242 days. The consumer will start adjusting and finishing the heating on their own.

The supply of heat to the living rooms takes 24 hours. In total, the gas is to be burned for 5808 hours. This is the maximum time required for the operation of gas equipment.

Axiom of heating calculations: for heating 10 square meters of housing requires 1 kilowatt of energy. Then the requirements considered in the example of the house will be 10 kilowatts. Actually, this standard is half lower due to a sudden early and warm spring, or a long and hot autumn, or winter frosts will not be the Urals, but the weak Crimean cold snaps. We agree that the energy consumption for heating a hundred square meters of living space will be 5 kilowatts.

Calculate the flow rate of gas per hour. Let:

0,92 - maximum efficiency of the heating unit;

H - the volume of gas consumption for heating the house 100 m2 in m3;

T - power for heating 100 m2, kilowatt;

C - the lowest heat of combustion of the main fuel is 10.175 kW / m 3.

Then T = T / (C * 0.92) = 0.5341 m3 / h.

Therefore, the gas consumption for heating the house 100 m2 in cubic meters will be 3102 m 3 .

Autonomous heating of the liquefied gas mixture

If natural gas is not supplied to the structure along the main line, then the boiler is connected to a cylinder or gasholder with a mixture of propane-butane. Accounting for liquefied gas is in kilograms. Therefore, the value of "C" from the calculation formula is 12.8 kW / kg.

The weight of one liter of the mixture is 0.54 kg. Calculate the weight of the hour volume of the mixture.

H = 5 / (12.8 * 0.92) = 0.4246 kg / h, liquefied mixture.

Now it remains to calculate the gas consumption for heating the house 100 m2 in liters.

The volume of A = 0.4246 * 5808 = 2466 liters.

How many refueling bottles will be needed for one heating season? In one cylinder 42 liters of fuel are placed. It takes only

2466/42 = 59 cylinders.

Price of issue

In the Chelyabinsk region, the cost of 1 cubic meter of natural gas is 6.15 rubles per cubic meter.

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 load on the consumer purse. On the insulation of windows and doors is said above. But there are also some other methods developed. Activities will add comfort to housing and reduce the cost of heating.

The amount of fuel for heating an individual house is reduced by any of the three measures, or by the whole complex:

  1. 1. Simple operation - installation in the input block of the heat curtain. Such models perform double work. In winter, the device cuts off cold air from the street, in summer the unit is turned on for cooling, while preventing the appearance of insects in the rooms. The heat curtains are equipped with overheating protection and remote control.
  2. Costly, but not difficult in execution - warm floors, which require heating the water in half the temperature of radiator heating. Water floors are inexpensive, and they have a plus: they warm, but do not overdry the air. However, remember that water floors, according to the rules, are installed only in a private house. In apartment buildings, consider the option of cable or film floor.
  3. Even in a house of 100 square meters. M will justify the installation of automatic regulation of heat supply depending on the outside temperature and the presence of people in the house.

Tips under the curtain

Modern gas heating boilers are used for both types of fuel after the burner is adjusted by a gas-fired master.

If the budget allows, then 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 the costs of gas fuel for a house of any area. Carefully apply the coefficients for the main gas and for the liquefied mixture of propane and butane.
