Model manufacturers

The Italian manufacturer Baxi is in great demand on the Russian market. Almost all regions of the country have service centers that repair equipment. The assembly of models and the production of parts is carried out in the homeland of the brand and in a number of European countries. Models with a capacity of 18-24 kW are supplied to the Russian market.

The Slovak manufacturer Protherm is known and distributed in all regions of the Russian Federation. The service network of this manufacturer is also widely represented in all major regions of Russia. The company manufactures boilers on its territory, components are produced in Slovakia and Germany. The line of models imported into Russia is 11-23 kW.

The Korean manufacturer Navien was introduced to the world relatively recently, but thanks to its practical design and affordable cost, boilers from this manufacturer quickly became popular. The production of parts and assembly of boilers is carried out directly in South Korea.

A very wide model line with a capacity of 10-40 kW is supplied to Russia.

The design of the compared models

The Baxi boiler is a boiler based on a bithermic heat exchanger and the ability to automatically switch to the DHW supply mode. The design provides for a circulation pump, an expansion tank with a volume of 6 liters, safety sensors. All leads are cast from copper. The heat carrier is heated by a heat exchanger alternately for two circuits.

The boiler from Proterm has a copper heat exchanger for the primary circuit and a second steel heat exchanger for the DHW circuit. A three-stage control valve is provided for switching the operating modes. It is also equipped with a German circulation pump and an expansion tank of 5 liters, security sensors.

There was already an article on the site about how to ensure uninterrupted power supply to heating boilers. You can find it by searching the site...

Gas boilers are designed not only for heating the house, but also for organizing a hot water supply system. There are several varieties of them, so before buying it is necessary to determine which design will be the most suitable.

All boilers on sale can be divided into two large groups: single-circuit and double-circuit. The first variety is intended solely for creating a comfortable temperature in the room, while the second is also used for supplying hot water. Double-circuit boilers are more compact in size, however, increased requirements are imposed on the conditions of use. In particular, in order to automatically shut off the hot water supply, the incoming flow must have a fairly high pressure. Because of this, it is almost impossible to save hot water.

For large rooms, double-circuit boilers will not be the most suitable option, especially if the water intake equipment is located quite far from the boiler. Single-circuit products are large and difficult to install.

Also, all boilers on the market can be divided according to the installation method - floor or wall. Floor-mounted ones are more powerful, differ in significant dimensions, they can be used to heat a room with an area of ​​\u200b\u200babout 600 square meters. m. In our ranking of the top 10 best gas boilers, all types of such heating equipment are presented. When compiling it, we take into account the price-quality ratio of the model, the opinions and reviews of customers, and many other factors. We hope that our rating will help you decide on the most suitable model.

In conclusion, useful videos

Wall-mounted boilers with two circuits, running on gas fuel, make it possible to provide hot water supply to radiators (one circuit) and taps (second circuit) at home.

Gas boilers are most often used to heat private houses.

Features of wall-mounted gas boilers for heating a private house

The wall mounting method imposes special requirements on the devices:

• compact dimensions;
• light weight;
• simple control;
• modern design.

Often, boilers are mounted on the walls not in separate buildings, like floor-standing ones, but directly in the utility rooms of houses - for example, in the kitchen.

For this, boilers are made relatively small size with control panel on the front. The case has a rectangular shape, which makes it easier to fit the device into the interior of the room.

The meaning of the parameters, which options are reliable

Power- a key parameter that allows the boiler to produce the required amount of heat for heating and hot water supply (DHW).

It is of great importance when choosing a suitable model and is calculated according to the principle 1 kW per 10 sq. m.

But not a single boiler should operate at maximum power, otherwise it will quickly fail. Therefore, when calculating the boiler power parameter, add 20% stock.

That is, for a house whose area is 100 sq. m., suitable boiler with power 12 kW.

Attention! If the boiler is required for year-round use, then you need to select two-stage device or power controlled unit.

Camera type affects immediately a number of characteristics of the boiler. The combustion chamber closed type allows you to install the boiler in a limited space. The main thing is that it should be next to the outer wall of the building, through which the coaxial chimney used with a closed chamber is removed.

For combustion chamber open type it will be necessary to equip the chimney and ensure the flow of air into the room. Due to the closed system, the closed type has higher productivity and savings than the open type. But the device with a closed chamber is more expensive.

When choosing the type of fuel it is important to note that modern boilers are adapted to work as on natural, so on liquefied gas. But it will be an advantage if there is a gas pipeline at the installation site of the boiler, since it is cheaper, more convenient and safer. The characteristics of each device indicate what is the fuel consumption when operating on natural and liquefied gas. By default, the gas boiler is set to run on natural gas, so when switching to a liquefied unit, you will have to reconfigure it.

Gas boiler efficiency- an important parameter in terms of the ratio of the costs of the operation of the device and the results of its work. The optimal efficiency range for wall-mounted boilers can be considered 90—95%. With a low efficiency, more fuel is spent, and for a high one, more expensive elements for the device are needed - for example, copper heat exchangers.

In wall-mounted double-circuit boilers are used heat exchangers copper and stainless steel. First transfer heat well second- more reliable in operation.

In the boiler can stand as a pair of m single-steel, and steel-steel heat exchangers. One is responsible for the heating circuit, the other for the hot water supply.

And there are also models of boilers with bithermic copper heat exchangers, the operation of which is organized according to the principle "pipe in a pipe".

Hot water supply- an important function of a double-circuit boiler. Therefore, when buying it, it is worth studying in the data sheet such an option as DHW performance. Usually the parameters are at what temperature and how many liters the boiler can heat. For houses where hot water from taps is used quite often, this moment plays an important role.

All these parameters must be taken into account in order to effectively use the gas boiler. At the same time, it is worth using its resource economically - for example, do not turn it on at maximum power for a long time. In case of regular care ( inspection once a year) and proper operation, the device can properly serve for a long time - on average up to 15 years. You can choose the appropriate option for a particular building by examining the rating of models. In it, the boilers are located as the coefficient of performance (COP) decreases.

Which heating gas boiler is better to choose

For buildings up to 200 sq. m. a wall-mounted boiler with a power of up to 20 kW will be enough. This figure is calculated according to the following formula - 1 kW x for every 10 m of a heated room with a ceiling height of 3 m. With a large quadrature, you will need a model of 30 kW and preferably a floor model. If you don’t need to heat the water if there is a boiler or column at home, then you don’t have to overpay for the second circuit.

1. For buildings whose quadrature does not exceed 150 sq. m., you can choose Lemax Premium-12.5N.
2. To heat rooms with a total area of ​​110 to 240 sq. m. will help Bosch Gaz 6000 W WBN 6000-24 C.
3. For large houses ranging from 150 to 350 sq. m. models Buderus Logamax U072-24K and Protherm Bear 40 KLZ are suitable.

The rating contains only the best gas heating boilers for houses and apartments, which have collected the most positive feedback. And that is why the choice in their favor certainly should not disappoint you.

The advantages of equipping a country house with a gas boiler are obvious: “blue fuel” is cheaper than electricity, and its stable supply inspires confidence in the uninterrupted supply of heat. Therefore, today in our article we will see the rating of wall-mounted double-circuit gas boilers in terms of reliability. this type of boilers is the most popular and in demand.

Double-circuit gas boilers solve two main tasks:

• home heating;
• supply of consumers with hot water.

Stopping the choice on a particular unit, it is necessary to rely on the structural elements:

1. Furnace chamber. An open combustion chamber assumes the presence of a separate chimney and a ventilation system that provides a guaranteed air exchange rate of 3-4 times per hour. In the absence of these devices, attention should be paid to a gas boiler with a closed-type combustion chamber.
2. Burner type. In units manufactured by modern industry, three types of burners are used:

• atmospheric, the principle of operation of which is based on the pressure in the system;
• modulated, capable of converting the heating coefficient;
• two-stage, switchable to 40% energy load at the maximum heating temperature of the coolant.
