Gas consumption for heating a house 100 m²: 200 and how much it consumes per month, what is the average in new boilers, it leaves

Independent or central heating is often based on the use of a gas boiler, which is mounted in a boiler room. The profitability of such heating should be determined at the design stage, determining the fuel requirements. Calculations are quite simple, the main thing is to know how many meters are heated and what is the power of the equipment.

Definition: how much gas a gas boiler consumes per month and year

The installation of gas boilers is considered the best solution for areas with a gas supply network. Natural gas has many advantages. This environmentally friendly product, affordable, has high heat dissipation. But when choosing a boiler, it is important to immediately determine how much gas the unit uses to heat different areas: from 80 m

² up to 400 m².

Factors affecting fuel consumption:

• Power of gas boiler;
• The area of ​​the house or apartment;
• Possible heat loss (the number of windows and doors, their tightness, wall thickness and other important parameters).

When buying a gas boiler for a long service, it is important to consider all the nuances of choosing a unit. It should be understood in advance how much gas is spent on heating a certain area and volume of the building. Only with a responsible approach can one have the economic benefit of such a purchase.

The main gas flow rate in gas heating boilers: formulas

The gas flow in boilers depends on the power of the heater. The necessary power calculation is carried out when purchasing heating equipment. In this case, they rely on the dimensions of the heated area. They calculate individually for each room, taking into account the lowest average annual temperature.

The resulting calculations will need to be divided in half. This is due to the fact that during the season the temperature changes from plus to minus. In this case, the gas flow will also be different.

Calculating power, use the ratio of kilowatts per 10 m2 of space, which is heated. Given the temperature differences, you need only half of the value, and this is only 50 watts per hour. For an area of ​​100 m2, 5 kW is enough. Formula for calculating natural gas: A = Q / q * B.

Description of the formula:

• A - the required amount of gas for heating;
• Q - boiler power for heating a house (for 100 m² 5 kW is enough);
• q is the minimum amount of specific heat, measured in kilowatts and depends on the brand of gas;
• B - boiler efficiency, percent should be transferred.

To determine the flow rate, simply substitute the source data in the formula. For a house with an area of ​​100 m² 0.557 cubic meters per hour is enough. For 150 m² 0.836 will be required, and for an area of ​​200 m² – 1,114. To find out how much the gas unit consumes per day, just multiply the resulting number by 24. Multiplying the indicator by 30 will determine how many cubes are needed for heating per month.

Simple calculation of gas boiler consumption for liquefied gas per month

The above calculation formula is used for other types of fuel. So you can calculate the amount of liquefied gas in cylinders. The calorific value of this type of fuel has its own differences. Liquefied gas is calculated in kilograms and then converted to liters.

Gas consumption from a gas holder per month:

• For an area of ​​100 m² need 560 liters;
• For 150 m² - 842 l;
• For 200 m² you need 1122 liters;
• Area 250 m² heated with 1403 liters

An ordinary cylinder holds 42 liters. To determine the number of cylinders per year, it is enough to divide the amount of gas by the standard size of the gas holder (42). Then you should multiply the number of cylinders by the cost of one to get the cost of such heating.

Average calculator for calculating gas consumption for heating a house

Finding out gas consumption over the past season is quite simple. It is enough to take into account the monthly indicators of the counter. When the heating season comes to an end, you just have to sum up all the data.

Next, consider the arithmetic average. But to calculate the required amount of gas at the stage of buying a boiler, you will need to use a special formula. Gasification of the autonomous system of a private house, cottage or apartment involves the use of an average calculator, while determining heat loss. This is only an approximate calculation.

Methods for calculating specific heat consumption:

1. Depending on the total area of ​​the heated rooms. They rely on the climatic conditions of the region. On 1m² need about 30-40 watts.
2. Given the total area of ​​the building. So every square meter of a room with a room height of 3 m requires 100 watts of heat. You will also need to consider the climate of the region.

The main thing in the calculations is to take into account the necessary boiler capacity, which is able to provide the premises with the required heat. When calculating, they are guided by the average indicator, by which 10 m² 1 kW of energy is used. Although this calculation is the simplest, it cannot take into account all the features of the region and the building itself.

The average calculator assumes that 1 kW of heat energy is needed per 10 squares of area.

Calculation of the use of gas will help not only to choose the right boiler, but also to reduce the cost of gas consumption. This will save on heating. So you can warm the house and find ways to reduce heat loss.

An example of calculating gas consumption for heating a private house from the network

A better example will help to understand the specifics and features of the calculations. This calculation can be used for both an apartment and a country house. First you need to collect the source data.

Initial calculation parameters:

• Area of ​​premises - 100 m²;
• Boiler power - 10 kW;
• The efficiency of the thermal unit is 95%.

For starters, the joules should be converted to kilowatts. 1 kW has 3.6 MJ. It should also be understood that the norm of 10 kW is used to heat the house in the coldest times. But there are not so many cold days for the season.

If you correctly calculate and arrange the operation of the boiler, then there is no point in operating the unit constantly.

On more favorable winter days, so many kilowatts are not required for heating. That is why it is customary to divide this parameter in half during calculations. Further, the obtained data is substituted into a special formula. And when you multiply the indicator by tariffs, you can calculate the economic part of gas consumption.

Having learned the required amount of fuel per hour, you can make calculations for the entire season. So the resulting number should be multiplied by 24 and get the indicator of consumption per day. Further, the data obtained are multiplied by 30 and receive the required amount of gas per month. The calculation for the season takes into account heating for 7 months.

Gas consumption for heating a house 100 m²

To find out how much heat is spent on space heating is quite simple. You can summarize the costs after the heating season or calculate the cost of heating even when buying a boiler. With the help of simple formulas and an online calculator, this event does not cause difficulties.
