Gas boiler heating a private home - which is better to choose?

Cottages and private houses are increasingly equipped with individual engineering lines, because few people like the interruptions in the supply of heating, hot water. In addition, far from all settlements there is the possibility of connecting to a centralized highway. When choosing a heating boiler, a number of nuances must be taken into account. They affect the technical characteristics of the building, the installed heating system, and many other criteria. In our article we will reveal the answer to the question: gas boiler for heating a private house - which is better to choose?

Types of gas boilers

When developing gas heating boilers, the features of their operation are taken into account. Engineers are constantly working on the modification of the internal device so that the gas is burned as economically as possible, while the heat efficiency increases.

Not every gas boiler installed in a private house will have the same efficient work and better heat transfer. When they decide to purchase a boiler for heating, consider the parameters:

• Type of heating system. Classic boilers work with radiator heating, and for the effective operation of some models, connection to a warm floor is required.
• Type of fuel. Typically, boiler equipment is selected that economically burns gas and is characterized by high heat transfer.

Operating parameters

Consider the performance characteristics used to classify boiler equipment.

Type of allocation

This parameter is the first one that is paid attention to when choosing. Models are floor and mounted, they vary greatly.

Wall mounted

Wall mounted boilers are most often volatile. To facilitate the design and reduce the load on the wall, designers use metal alloys, a bithermic heat exchanger.

If we consider the best double-circuit gas boiler, then in its design there is a tank in which water is heated. In wall single-circuit models, such a modification is absent. Such models are used only for heating, but if there is a need, an external tank is connected, in which the DHW is heated.

Deciding which wall-mounted gas boiler is better is not so simple, because they all save space and are very easy to install. Some models can even be integrated into a kitchen cabinet. Therefore, it is necessary to focus on the specific characteristics of the equipment of the model you like.

Floor

Floor gas boilers do not have a performance limit, unlike mounted counterparts. They can be single and double circuit. For the manufacture of a heat exchanger, steel or cast iron is used. Such a boiler is not always convenient in that it is most often installed in a kitchen, which already does not differ in large area.

Important! The choice of a gas boiler for heating a private house with natural gas, more precisely, the type of its placement, is based on the heated area. If the area of ​​the house exceeds 250 square meters, it is better to stay on the floor model of the heat generator, as it is characterized by higher power rates. Such units cost less, but instead take up more space.

Type of gas combustion chamber

Heating equipment is available in three configurations of the combustion chamber.All of them have different efficiency and installation requirements.

Atmospheric

The atmospheric model is the most reliable boiler, which is characterized by a simple design and operating principle. The design is equipped with an open combustion chamber. When gas is burning, air from the room is used. To change the adjustments and settings, thermomechanical regulators are used.

Important! The main disadvantage of such models is the high gas consumption, complex installation requirements and a fairly low efficiency.

Turbocharged

The turbocharged heat generator is characterized by the presence of a sealed combustion chamber. In order for the gas to burn, the air intake is not from the room, but from the street. Air is supplied to the burner, and the products of combustion are discharged by a fan, that is, by forced means.

Modern boilers are usually equipped with two fans, with the help of one air is supplied, and the second - flue gases are removed.

Such models are practically the best gas boilers for a private house, since:

• They are economical.
• When replacing a turbocharged atmospheric model, gas consumption is reduced by almost a third.
• Such heat generators are characterized by high efficiency and low requirements, due to which there is a reduction in the required area of ​​the boiler room.

Important! The disadvantages are represented by volatility and noise during operation.

Condensation

Condensing boiler - the most economical. The design assumes the presence of a closed combustion chamber and modulation burner. Such boilers are volatile.

There is a condenser in the heat exchanger. Condensate is collected in this unit and its thermal energy is accumulated.

For economical operation of the unit, natural or liquefied gas is required. Particular benefit is manifested if the device is connected to a gas tank or gas installation.

Important! The disadvantage is that such boilers are connected to a low-temperature heating system, de-heating performs a warm floor, and with the help of radiators, the air temperature in the rooms is only maintained.

Choosing the best gas boiler for heating a private house according to the design of the combustion chamber, one should take into account the type of fuel that will be used and the type of heating system.

Number of circuits

Now a lot of various modifications are produced, boilers can be single and double circuit, but they have additional functions. Each solution has its pros and cons:

• A double-circuit boiler heats water and is used for heating. It has two separate heat exchangers. The rating of wall-mounted gas boilers for reliability and quality is headed by models in which a bithermic heat exchanger is used to reduce weight. When heating water, the boiler operates in the instantaneous water heater mode. In the summer, such an apparatus works like an ordinary gas column; there is no heating of the liquid in the heating system.
• In a single-circuit boiler, the coolant in the heating system is heated. Further, it can be converted for domestic hot water, while an indirect heating boiler is connected.

Important! Not all manufacturers offer models of a wall-mounted single-circuit gas boiler, since it is not very practical and has little demand. Of course, the optimal solution is to install a floor unit, which has much better performance and build quality.

Choosing a gas boiler

Of course, not only the design and operating parameters affect the choice of a boiler for heating. You should pay attention to the parameters of the following factors:

• Power;
• Manufacturer's factory;
• Cost.

Calculation of boiler power

When calculating the power of the boiler for heating, several methods are used. Find out which of them are the most popular:

• Online calculators. Initially, their development was aimed at assisting consultants.But now they are on many sites that help to select heating equipment and boilers. When a choice is needed, the consumer enters data on the area, the number of windows and doors, the degree of thermal insulation, and much more. In the end, you get the optimal result.
• Self calculation. To calculate the approximate power of the boiler, a simple formula of 1 kW = 10 sq.m. is used. Thanks to such calculations, it is possible to obtain an inaccurate value, which means that a power adjustment will be required, taking into account cold weather in winter and the needs of hot water.

This is practically the best single-circuit wall-mounted gas boiler. It is notable for its small size and affordable cost. It is possible to change from using natural gas to liquefied gas. This option is often used for heating cottages.

Such a boiler is distinguished by the following advantages:

• Low cost;
• Compactness;
• Light weight;
• independence from the power grid;
