Powerful gas boiler. Gas boiler manufacturers ratings

The heart of an autonomous heating system is a hot water boiler. The air temperature in the house and the amount of heating costs depend on its quality, functionality and efficiency. In order not to be mistaken in choosing this important device, it is necessary to study every detail and function of the device. The rating of wall-mounted gas heating boilers will help to save time on familiarization with the technique - the top positions in it are always occupied by equipment that has earned the trust and recognition of other users.

Classification of gas boilers

Lightweight and compact wall-mounted gas heating boilers are suitable for autonomous systems in individual cottages and city apartments. This group unites several types of equipment that are fundamentally different from each other in terms of design and operation. Here is a list of the most important design features that you should pay attention to before choosing a boiler:

1. Number of circuits: single-circuit are focused only on heating, and double-circuit in parallel provide the functions of hot water supply.
2. Combustion chamber type: open or sealed (closed).
3. Exhaust gas removal method: natural or forced.
4. Energy dependence: non-volatile wall-mounted gas heating boilers work without being connected to electricity.
5. Burner type: atmospheric or modulating with automatic power control.

Important points

When choosing a double-circuit boiler, people are guided by standard requirements - power, functionality, cost, manufacturer, etc. There are several points that are rarely mentioned, but they are very important.

1. Type of instalation. The boiler can be hung on the wall or placed on the floor. If the device has a built-in boiler, then it often has a floor-standing design. The same applies to models with a power of more than 30 kW. Typically wall mounted appliances are more compact and lighter in weight. This is justified by the fact that they have to be hung, which means that they will experience an increased load on the floors. Therefore, floor models should be bought by those who cannot use the wall as a support, or if you plan to buy a very powerful device.
2. Built-in boiler. This is a very handy addition. Usually a volume of 60-300 liters is enough for 2-4 people. Household habits are also very important. If the boiler is to be built in, then you need to select it in accordance with the capacity of the existing boiler. Usually, such devices are initially designed for certain volumes of the boiler. Therefore, this nuance must be taken into account in advance.

1. Ordinary or condensing? The latest models make the most of all the energy that is produced during operation - even that which is in the water vapor. Therefore, their level of efficiency is strikingly higher (on average by 10%) than that of ordinary double-circuit boilers. Accordingly, such devices consume less fuel, due to which the payback comes faster.
2. Control. It can be manual or automatic. Usually, when installing a boiler, certain parameters are initially set for it. Temperature controller, which in its simplest design is a mechanical thermostat. It turns on the burner when the coolant begins to lose its set temperature. He will also turn it off if the value becomes higher than the set value. In modern models, management is carried out by special programs that minimize human intervention. In addition, they are more sensitive to temperature changes in the environment. Although initially such boilers are expensive, they pay off quickly during operation. If desired, you can gradually improve the device by connecting various modules to it.

Important! Before each new start-up, the device must be inspected by specialists. They clean and inspect for any faults.

Knowing these factors will help you choose the right device.

Currently, popular and demanded wall-mounted gas boilers are used for high-quality heating of premises. This is explained by the fact that gas is the most accessible and at the same time inexpensive fuel. Markets and supermarkets offer a large number of different models of gas boilers, which differ in technical characteristics and prices. Therefore, it is rather difficult to choose the appropriate option. To solve this problem, you should first study the technical characteristics of the best equipment produced by various manufacturers and compare prices.

In the manufacture of such boilers, modern automation and new metal alloys are used. They have a low exhaust temperature, so they are practically fireproof.

All wall-mounted gas equipment according to the type of chambers is divided into two types:

Open heating devices in which air draft occurs naturally. In them, combustion products are emitted through the chimney. Combustion air is taken from the room.

Closed structures are equipped with a forced air ventilation system. For their work, they take air from outside the premises, and exhaust gases are thrown outside. Such models do not need an additional smoke exhaust system. In addition, they are small in size and weight.

Those who want to purchase a gas heating boiler will need to calculate the required capacity of the equipment. For every 10 sq. m. premises with a ceiling height of no higher than three meters, one kilowatt of device power will be needed. If the power of the boiler is not needed very much, then you can stop your choice on wall-mounted equipment. In addition, double-circuit wall structures can also provide hot water supply, as well as create additional heating circuits in the form of a "warm floor".
