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 is needed to heat a unit of individual house area.

Two more 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 an economically advantageous speciesfuel was selected firewood. 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 epoch of development of green energy has come andoperation of renewable energy sources in the form of solar radiation and wind. 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.

Contaminant	Emissions from combustion, maximum
	Coal, g / t	Natural gas, g / m3
Ash	% of the working mass of fuel	no
Carbon dioxide CO2	3000	2000
Nitrogen oxides in terms of NO2	14	11
Sulfur oxides in terms of SO2	0,19	-
Benzapyrene	0,014	0,001

As can be seen from the table, the content of hazardous substances for human health is lower for gas than for 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 consideredeither 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 a house to an autonomous heating system, natural liquefied gas in cylinders is used and the account is maintained 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.

Walls, roof, doors and windows - sources of lossesheat. No powerful heating boiler will save, if the doors and windows are not closed tightly, if there are cracks in the wall seams and the ceiling. 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 SouthernUrals. According to the rules, the heating interval is set 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 squares 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;

С - the lowest heat of combustion of the main fuel 10,175 kW / m^3.

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

Consequently, the gas consumption for heating the house 100 m2 in cubic meters will be 3102 m³.

Autonomous heating of the liquefied gas mixture

If natural gas is not supplied to the structure bythe 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.

R = 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 L = 0.4246 * 5808 = 2466 liters.

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

2466/42 = 59 cylinders.

Question price

In the Chelyabinsk region the cost of 1 cubic meter³ natural gas is equal to 6.15 rubles / m³.

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. Thermal curtains are equipped with protection against overheating and remote control.
2. Costly, but not difficult in performance - warmfloors, which require heating the water in half the temperature of the 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 multi-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 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 the costs of gas fuel for a home of any area. Carefully apply the coefficients for the main gas and for the liquefied mixture of propane and butane.
