Cottages and private houses are increasingly equipped with individual engineering lines, because there are very few people who like the interruptions with heating and hot water supply. In addition, not all settlements have the opportunity to connect to a centralized highway. When choosing a boiler you need to take into account a number of nuances. They affect both the technical characteristics of the building, and the installed heating system, and many other criteria. In this article, we will reveal the answer to the question: What is the best choice for a gas boiler for heating a private house?
to the contents ↑Types of gas boilers
The development of gas heating boilers takes into account the peculiarities of their operation. Engineers are constantly working on the modification of the internal device to ensure that the gas is burned as economically as possible, and the heat efficiency is increased at the same time.
Not every gas boiler installed in a private house will have the same effective work and better heat transfer. When making a decision to buy a boiler for heating, consider the parameters:
- Type of heating system. Classic boilers work with radiator heating, and for effective operation of some models it will be necessary to connect to a warm floor.
- Type of fuel. Usually they choose the boiler equipment, which economically burns the gas and has a high heat output.
Operating parameters of
Let's consider the performance characteristics used for the classification of boiler equipment.
Type of placement
This parameter is the first one to which attention is drawn when selecting. Models are floor and hinged, they are very different.
Wall-mounted
Wall-mounted boilers are most often volatile. To facilitate the construction and reduce the load on the wall, the designers use metal alloys, a bithermal heat exchanger.
If we consider the best dual-circuit gas boiler, then in its design there is a capacity in which water is heated. For wall-mounted single-circuit models, such a modification is not available. Such models are used only for heating, but if necessary, a remote tank is connected in which the hot water is heated.
Solve, the wall gas boiler - which is better, is not so simple, because they all save space and are very easy to install. Some models can even be built into the kitchen cupboard. Therefore, you need to focus on the specific characteristics of the equipment you like the model.
Floor standing
Floor standing gas boilers do not have a performance limitation, unlike hinged analogues. They can be single- and double-circuit. The heat exchanger is made of steel or cast iron. Such a boiler is not always convenient because it is most often installed in the kitchen, which does not have a 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, since it has higher power indicators. Such aggregates are smaller, but they occupy a larger space in exchange.
Type of gas combustion chamber
Heating equipment is available in three combustion chamber design configurations. They all have different economy and installation requirements.
Atmospheric
The atmospheric model is the most reliable boiler, which has a simple design and principle of operation. The design is equipped with an open type combustion chamber. When the gas is burning, the air coming from the room is used. To change the adjustments and settings, thermomechanical regulators are used.
Important! The main drawback of such models is the high gas consumption, complex installation requirements and rather low efficiency.
Turbocharged
Turbine 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 premises, but from the street. Air is supplied to the burner, and combustion products are diverted by a fan, that is, by a forced method.
Modern boilers are usually equipped with two fans, with one supplying air, and the second - discharging flue gases.
Such models are practically the best gas boilers for a private house, because:
- They are economical.
- By replacing the atmospheric turbine model, gas consumption is reduced by almost a third.
- Such heat generators are characterized by high efficiency and low requirements, thanks to which the required boiler room area is reduced.
Important! Disadvantages are represented by energy dependence and noise in the process of work.
Condensing
Condensing boiler is the most economical. The design assumes a closed combustion chamber and modulation burner. Such boilers are volatile.
There is a condenser in the heat exchanger. In this node the condensate is collected and its thermal energy is accumulated.
For economical operation of the unit, natural or liquefied gas is required. Especially the benefit is manifested if the device is connected to a gas generator or a gas-cylinder unit.
Important! The disadvantage is that such boilers are connected to a low-temperature heating system, the heating is performed by a warm floor, and the radiators only maintain the temperature of the air in the rooms.
When choosing the best gas boiler for heating a private house by the design of the combustion chamber, it is necessary to take into account the type of fuel to 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 pluses and minuses:
- A dual-circuit boiler heats the 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 bi-thermal exchanger is used to reduce weight. When the water is heated, the boiler operates in a flowing water heater mode. In the summer, such an apparatus works, like an ordinary gas column, does not heat the liquid in the heating system.
- In a single-circuit boiler, the heating medium in the heating system is heated. Further, it can be converted for DHW, 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 highly advisable and has little demand. Of course, the optimal solution is to install a floor unit, which has much better performance and build quality.
to contents ↑Selection of gas heating boiler
Of course, not only the design and operating parameters affect the selection of the boiler for heating. Attention should be paid also to the parameters of the following factors:
- Capacities;
- Factory of the manufacturer;
- Cost.
Calculation of boiler output
When calculating the boiler's power for heating, several methods are used. Let's find out which of them are the most popular:
- Online calculators. Initially, their development was aimed at helping consultants. But now they are on many sites that help to select heating equipment and boilers. When a choice is required, 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 output of the boiler, a simple formula of 1 kW = 10 m 2 is used. Due to such calculations, it is possible to obtain an inaccurate value, which means that a power adjustment will be required, taking into account the cold in winter and the demand for DHW.
The best domestic models of
There are many foreign manufacturers, but the best Russian-made gas boilers are headed by the Zhukovsky plant. Consider the most productive models
AOGV-23.2-3
This model is distinguished by improved environmental performance. In addition, its equipment is imported automatic Honeywell. The boiler is equipped with a pointer thermometer and piezopodging. It can be used for heating industrial and domestic premises.
The boiler is different:
- Affordable cost;
- Reliability( automatic welding and seamless technology);
- Unpretentiousness;
- Economical;
- Environmentally friendly;
- Simple control;
- Easy maintenance;
- Stability of operation even if the gas pressure is low;
- Independence from the power grid;
- Built-in overheating sensors.
AOGV 11.6-3 Comfort
This is practically the best single-circuit wall-mounted gas boiler. It is small in size and affordable. It is possible to reconfigure from the use of natural gas to liquefied gas. This option is often used for heating cottages.
Such a boiler is distinguished by the following advantages:
- Low cost;
- Compact;
- Light weight;
- independence from the mains;
- unpretentiousness;
- built-in piezo spark;
- possibility of reconfiguration for the use of liquefied gas.
Important! With all this, do not forget about the shortcomings:
- A small area of heating;
- Not quite accurate pointer temperature indicator;
- Imperfect automatic protection system.
AKGV - 23,2 EM
The rating of floor gas boilers would be incomplete without this model produced by Ochag:
- It is not very expensive, and the model is non-volatile.
- The boiler does not need to be plugged into an outlet, it is ignited manually. This means that it will not suffer as a result of voltage fluctuations in the network.
- Its construction is simple and safe.
As you can see, for the arrangement of heating in the house there are a lot of options. The most important thing is to choose the right model and connect it correctly. Then on the coldest day in your home will always be warm and cozy.
