Gas heating at home – how much does it cost?

Different heating systems are used in apartments and houses. One of the common types is gas heating. This is a convenient solution that does not require regular combustion in the furnace and fuel loading. This solution is appreciated by people who spend a lot of time outside the house and at the same time want an appropriate constant temperature there..

Gas heating in the house

Currently, this method of heating houses is one of the most popular in Russia. When choosing such a technique, we have two types of connection to choose from – you can use an external network or store gas in a liquid state in a special container located outside the house. The installation requires the supply of gas to the house through a properly designed connection, as well as the creation of an internal gas installation that will supply gas to heat sources. The heat produced in the boiler is transferred to the central system, due to which the whole house becomes warm.

Types of gas heating at home

When classifying boilers, an important characteristic is the fuel used for their operation. Heating boilers are gas, electric, diesel or solid fuel. In gasified areas, gas models of boilers are often used. This equipment operates on natural gas. The advantage of this energy carrier is availability, environmental friendliness, compactness, and ease of use. The only disadvantage of gas boilers is explosion hazard, which is why they must necessarily meet fire safety standards. Installation of a gas boiler for heating a house requires obtaining certain permits, the presence of a room intended for the installation of equipment, with a chimney and a reliable ventilation system.

Any types of gas heating boilers for a private house cannot be installed close to the wall, and the equipment must also have special automation that blocks gas access in the event of leaks. Installation of equipment is a serious process on which your safety and the safety of all residents of the house depend. The main characteristic of such equipment is power. The choice of equipment is influenced by two factors:

  1. Climatic conditions.
  2. Estimated heat loss of a specific building.

Based on power indicators, the equipment is divided into three groups:

  1. High power – up to 15,000 kW.
  2. With an average power – power does not exceed 1700 kW.
  3. With low power – power in the range from 4 to 65 kW.

Gas heating in the house, which is better – main or liquefied?

For heating with a gas boiler, liquefied or mains gas is used. To answer the question, you need to conduct a comparative analysis in two ways:

  • Trunk. This gas is environmentally friendly, as it consists of methane purified from impurities. Only a small amount of odorant remains in the gas, which makes it possible to detect gas leaks. Despite the advantages, the installation is not straightforward. This will require the approval of the documentation in the official bodies, checking the pressure in the pipes, the quality of the wiring.
  • Eaten. Surely you have seen the very bright red cylinders in which propane-butane is stored. Provided that an underground tank is installed for the safe storage of cylinders, they will not be inconvenient. Replenishment of the reservoir is required once or twice a year. This method is suitable for any boilers..

It is advantageous to use liquefied gas in comparison with main gas, but it is important to remember that one cylinder contains approximately 50 liters of gas. One cylinder must be changed every 2-3 days. With main gas, it enters apartments or houses through pipes.

Connecting gas heating in a private house

Gas heating with a boiler is a simple system. As a result of heating the heat carrier by obtaining the temperature from the combustion of the gas, it is circulated through pipes and radiators. After that, the coolant returns to the boiler equipment in a cooled state..The principle of gas heating of a private houseis quite simple, and the circulation of the heat carrier in the system can be natural or forced.

Natural circulation is ensured through the use of expansion tanks. The highest point of the building is used for its installation. Circulation occurs due to the density difference between cold and hot water. Heated water has a lower density than cold water, so it is forced upward. When the upper point is reached, the heated water enters the pipes, and when it returns to the boiler, it already has a lower density. Then the cycle repeats. To create such a system, the boiler must be located below the radiators, while providing a sufficient difference in level. To ensure the prompt drainage of hot water to the batteries and cold water to the boiler, a slope is created when laying pipes in horizontal sections. Experts recommend using polypropylene pipes with an overestimated diameter. At the same time, it is recommended to minimize pipe bends and bends..

For forced circulation, a pump is used, and in some device models it is already built-in. Installation of the pump allows you to mount boilers anywhere, forgetting about the need to tilt the pipes. It is important to remember that the pump is powered by electricity and in case of power outages, you will have to use the natural way.

Gas heating – costs

The answer to the question,how much does gas heating at home cost, it is impossible to give unequivocally. It depends on the cost of a cubic meter of gas in a given place during a certain period. Depending on the supplier plant, the price for 1 m3 of gas may be different. The unit for calculating the energy requirement of a building is the kilowatt-hour per square meter (kWh / m2), with which you can estimate the cost of heating. A well-insulated building with sealed windows requires about 110 kWh / m2, and an energy efficient building requires up to half that. Passive buildings, that is, with additional energy sources, have an energy requirement of only 15 kWh per 1 m2.

The type of oven that was installed in the system also affects the cost of heating. This is important because each type of equipment has a specific combustion efficiency. Gas heating with a traditional boiler with an open or closed combustion chamber will cost almost twice as much as using a pulse boiler. The downside of this solution is the cooling of the boiler room, which increases the cost of heating the house. Another solution is to use impulse equipment, which is more technologically advanced, and combustion takes place without burners. The disadvantage of this solution is the high installation cost. The last solution is a condensing boiler, which recovers heat from combustion. These are quite economical boilers, moreover, they do not take up as much space as impulse boilers..

Calculation of gas heating of a private house 150 m2?

It is impossible to answer this question unequivocally. The actual cost of heating a house with gas each time is determined by the type of house, as well as how it is insulated, whether it is energy efficient. For example, if we assume that a building with the aforementioned floor space is not sufficiently insulated or energy efficient, the annual heat demand of such a building will be at least 24,000 kWh. If the house is energy efficient and better insulated, heating costs can be reduced by up to 30-40%.

What are the costs of installing gas heating?

In the case of this method of heating a house, the installation price depends on its design. The final installation cost includes:

  • the cost of the furnace, which depends on the selected type of furnace (traditional, impulse or condensing boiler).
  • cost of transition pipes, fittings and fittings.
  • possible additional costs (e.g. additional pipes).

Such heating is very convenient, although quite expensive. When deciding on such a decision, it is worth analyzing the assembly costs, and then carrying out a careful calculation of heating the house with a gas boiler..
