For a private house or a country cottage, with the onset of a cold period, the problem of heating becomes an urgent one. Thanks to technological progress, today it is possible to create an autonomous heating system in your home using heating boilers and other related equipment. Coal, firewood, electricity can be used as fuel, but natural gas is still the most affordable and cheapest. It is this aspect that is the main reason that today many citizens are trying to use gas to heat their homes. Properly designed autonomous gas heating of a private house will allow you not only to save your own money, but also to calmly expect the onset of cold weather.

Despite the fact that today not all regions of our country are covered by a network of main gas pipelines for household gas, there are other, no less convenient ways of heating residential buildings with gas.

Autonomous gas heating — the main essence and principle of operation

What is autonomous heating on gas? This question can be answered simply and clearly. The heating system of the building operates offline, using natural gas as fuel. The method of gas supply can be centralized, through a central line, or individual, using gas cylinders or a gas tank.

The popularity of this type of heating is due to the ease of installation of the entire system and affordable price, in comparison with other heat sources. Let’s take a closer look at the advantages of gas heating of a private house and, if any, with the disadvantages.

Advantages and disadvantages of autonomous gas heating

Gas boilers in terms of economy and efficiency are by far the most profitable heating appliances. Comparing the operation of a gas boiler with an electric heater of the same power, the first option looks preferable. After installing an autonomous heating system on gas, the investment pays off already for 2-3 years of operation.

An autonomous gas heat-generating boiler, according to its technical characteristics, is capable of solving a whole range of tasks at the household level. The boiler will not only quickly and efficiently provide the required temperature inside the house, but also provide domestic hot water. In many respects, a natural gas heating boiler is best suited for autonomous heating of private houses.

Let us consider in more detail the advantages that natural gas heating technology has:

  • natural gas has one of the highest heat transfer coefficients;
  • low inertia of gas boilers ensures rapid heating of the coolant;
  • availability and low cost of natural gas;
  • heat-generating equipment equipped with automation is able to work without the presence of a person;
  • various designs and types of gas boilers are able to effectively heat both small residential premises and large objects;
  • gas, unlike fuel oil, oil, firewood or coal, is an environmentally friendly type of fuel;
  • modern models have a high degree of reliability and are designed for long service life.

The list can be continued if we switch to numbers and calculations, however, there are some disadvantages in gas boilers, which can rather be called the intricacies of operation and design features.

Installation of a gas boiler and the entire heating system in the house is carried out only by specialists with the appropriate qualifications. The installation of boiler equipment is preceded by a lengthy procedure for obtaining permission for autonomous gas heating.

On a note: Before starting the installation, it is necessary to have a ready-made project of the heating system on hand, which must contain all the necessary data and calculations. The project must be completed in accordance with existing SNiPs and GOSTs. Only the approved project, which has been approved by the energy company, is being put into operation.

The gas heating system puts forward special requirements for the owners of private houses, the observance and implementation of which is a guarantee of the efficient operation of the heating equipment and the safety of the residential facility.

Choosing an autonomous heating system

Having the funds and the desire to make autonomous gas heating in your home is half the battle. You will have to spend a lot of effort to obtain the appropriate permission from regulatory authorities and authorities. It is at this stage that you will have to choose what type the future autonomous heating system will be, what tasks and requirements for heating equipment will be set.

The answer to many questions will be given by the design of the heating system. The type of autonomous heating system correctly selected for real conditions, the corresponding hydraulic and thermal calculations accurately and correctly made, will ensure the safe installation of equipment in the future.

Today, the two most common types of home heating are:

  • radiator;
  • water heated floor.

Both systems have their pros and cons. In the first option, we can talk about quick and convenient installation. Laying pipes, installing a boiler and connecting radiators is a common task and is not particularly difficult for professionals.

Important! Heating radiators give a greater effect in rooms with a large glass area. During the heating process, a thermal curtain is created in front of the windows, creating the necessary temperature balance.

There are no significant disadvantages in such a system. The installation cost is not high, but it must be taken into account: each radiator costs a lot of money, plus the cost of the boiler and consumables that will be required for laying communications. The larger the heated area, the higher the costs.

In terms of efficiency, a water-heated floor is more profitable. In the course of work due to the heated floor surface there is a uniform heating of all internal space of the room. The disadvantages include the high cost of equipment and the complexity of installation.

On a note: Warm air rises uniformly upwards, while cold air descends downwards and so on in a circle. Heating radiators heat the air located directly next to them. In a heated room, air exchange is carried out slowly.

*

For example: air at a height of 1.5 m above the floor warms up to 200C, then at floor level the air warms up to only 17-180C. Under the very ceiling, the air is even warmer 24-250C. As a result, heat losses through the attic and wall panels increase. The boiler works in enhanced mode, fuel consumption increases.


With a water floor, the situation looks different. The temperature required for the operation of the «warm floor» system is lower than the temperature required for radiators. The gas boiler is able to operate with maximum efficiency, and fuel consumption in this case is minimal.

When choosing a heating system for your home, do not forget that the warm floor has a limited heat transfer — only 50-70 W per m2. In rooms of a large area, with a large number of windows and external walls, significant heat losses will occur.

The diagram shows a traditional two-pipe heating system for most private sector houses.

What is a gas boiler for independent heating

Autonomous gas boilers offered to consumers today meet all possible technological requirements that are set for heating equipment of this type.

The boiler is selected depending on the goals and objectives. For large country houses, cottages with an area of ​​more than 150 m2 the floor double-circuit boiler, with a power of 30-75 kW, will be optimal. Often in large country estates, with many buildings and large interior spaces, hot water boilers are installed. Powerful units capable of providing heat to all buildings and premises available on the farm, at the same time providing all inhabitants of housing with hot water.

*

For small buildings, for country houses, the best option would be a wall-mounted gas boiler, which is quite capable of heating three or four rooms with a total area of ​​​​up to 80-100 square meters. m. Boilers come with forced ventilation and atmospheric.

For most suburban buildings, independent heating is preferred, in which there is no power supply. A single-circuit gas boiler, in which the coolant naturally spreads through the system, does not need a circulation pump and a fan to force air into the combustion chamber. Such autonomous heating systems are completely independent of the power supply, but their efficiency is an order of magnitude less than that of boiler equipment equipped with electrical appliances and mechanisms.

conclusions

Gas is the most accessible and cheapest type of fuel. By installing a gas double-circuit boiler of the corresponding model in your house, you get interior heating and hot water supply.

If you have a problem with centralized gas supply, there is a way out. Install a gas storage on your site — a gas tank.

One refueling capacity of liquefied gas is enough for 6-7 months of the heating season. In this situation, your heating system is almost completely independent, there is a real cost-effectiveness and efficiency of autonomous gas heating.
