How to calculate how much gas a gas boiler consumes per month?

In areas with access to gas supply networks, the installation of gas water heaters as equipment for heating and / or hot water systems is an obvious and optimal solution. Natural gas is inexpensive, has a high heat output during combustion and, in addition, is one of the most environmentally friendly fuels due to the minimum amount of harmful emissions into the atmosphere during combustion. The question of how much gas a gas boiler consumes is the main criterion when choosing a gas boiler by a consumer.

Several factors influence the fuel consumption parameter at once:

For equipment designed for many years of operation, such as a gas boiler, gas consumption is a key indicator, because an expensive boiler with low fuel consumption during operation for a decade is a more cost-effective solution than cheap equipment with increased gas consumption.

Calculating the average monthly gas consumption is not very difficult. To do this, first determine the gas flow rate per hour for this gas boiler. The power of gas equipment depends on the area of ​​\u200b\u200bthe room. It has long been empirically determined that for a residential building with a ceiling height of 3 m, 1 kW of thermal energy per 10 square meters is needed. m. area. It is logical to assume that by dividing the total area of ​​​​the premises by 10, they receive the necessary amount of thermal energy for heating the building.

To obtain 1 kW of thermal energy, the gas consumption is 0.112 cubic meters, multiplying this figure with the required amount of heat for the building, we get the hourly gas consumption for heating the house. Accordingly, by successively multiplying the resulting figure by 24 and 30, the daily and monthly gas consumption for heating is obtained. Multiplying the monthly consumption by 7 months (the duration of the heating period), the annual gas consumption for heating is obtained.

It should be borne in mind that the boiler is not always turned on at full capacity. With the duration of the heating season within 250 days in full load mode, the equipment operates for no more than 100 days, so the resulting annual gas consumption can be divided in half without doubting the reliability of the result.

Varieties of gas boilers

Heating boilers according to their design are divided into single-circuit and double-circuit. Single-circuit devices are used exclusively for space heating. Dual-circuit models also provide hot water.

Single-circuit boilers

Single-circuit ones are very simple in design - in them, the burning fuel heats the heat-carrying liquid flowing through the internal pipelines of the heat exchanger, which subsequently flows through the pipes of the system circuit to the heating devices in the premises.

Single-circuit gas boilers are structurally designed for heating, however, when an additional indirect heating boiler is connected, it is possible to obtain hot water supply in the house.

It should be borne in mind that such a connection creates instability in the operation of the heating network, since in the event of a peak withdrawal of hot water for domestic purposes, the temperature of the coolant in the heating system will inevitably fall.

Double-circuit boilers

Double-circuit boilers with their design provide both space heating and hot water supply, due to the presence of an additional heat exchanger designed specifically for these purposes. This execution scheme is more beneficial in terms of comfort, and consumer reviews are always positive for such devices as double-circuit gas heating boilers.

The market offers a wide range of boilers of all types, capacities and technical equipment in the form of timers and thermostats from manufacturers from different countries.

Their final choice depends only on the wishes and financial capabilities of the consumer. In any case, regardless of belonging to the country of manufacture of the equipment, it is possible to achieve significant fuel savings if the tightness of windows and doors is observed, as well as high-quality thermal insulation of the enclosing structures of the heated building.

The use of power regulators and timers, which allow you to adjust the operation of the boiler to your needs with respect to adjusting temperatures in a significant range at specified intervals, will provide additional savings on heating your home.
