Choosing a gas heating boiler. Ratings of gas boiler manufacturers. Closed and open combustion chamber

The floor-standing boiler is designed to operate on natural or liquefied (retrofit) gas. High power allows you to heat not only residential premises, but also production areas up to 320 m2. To supply hot water, it is possible to connect a boiler.

A cast iron heat exchanger in 5 sections will ensure reliability and increase service life (due to the fact that cast iron is 2 times less susceptible to corrosion than steel). For stable operation from the network, the installation of a voltage stabilizer is required.

Since the Vaillant atmoVIT VK INT 324 1-5 boiler has an open combustion chamber, it requires the installation of a vertical chimney for the natural removal of combustion products. A control system with a display makes it easier to set up and control the operation of the boiler.

Pros:

• Possibility of connecting a boiler.
• Gas control system.
• Automatic diagnostics.
• Reliable operation.

Minuses:

• The expansion tank is not included.
• Heavy weight (99.9 kg).

The heart of an autonomous heating system is a hot water boiler. Both the air temperature in the house and the amount of heating costs depend on its quality, functionality and efficiency. In order not to make a mistake 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 you save time on getting familiar with the equipment - 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 combines several types of equipment that differ fundamentally 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 ones are focused only on heating, and double-circuit ones provide hot water supply functions in parallel.
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 operate without being connected to electricity.
5. Burner type: atmospheric or modulating with automatic regulation power.

The best condensing boilers

Condensing boilers are more expensive, but the overpayment is more than compensated by economical gas consumption and high efficiency of heat generators, amounting to at least 95-98%. It is believed that the best wall-mounted gas heating boilers of this type are produced by the German company Viessmann.

Taking the lead in the condensing appliance segment is the compact and elegant Viessmann Vitodens 100-W with a maximum output of 35 kW and a hot water preparation speed of 14 liters per minute.

The second position in the ranking is occupied by the single-circuit Ariston Clas Premium Evo System 35 FF, adapted for low gas pressure. The device is equipped with a primary copper heat exchanger and a secondary plate-type steel heat exchanger. The maximum power of the device is 35 kW.

On the third line is the German Bosch Condens 5000 FM heat generator, which supports operation in a cascade and with solar collectors. The device is equipped with electronic control of the composition of the gas-air mixture and a unique heat exchanger with patented tube configuration technology.

Two in one: the best models of dual-circuit heat generators

Combination boilers solve two important problems at once: they heat the house and provide it with hot water. These devices are in demand among owners of individual buildings and apartment residents who do not want to depend on centralized hot water supply.

The Vaillant turboTEC PRO VUW with forced exhaust of flue gases and a built-in plate water heater with a capacity of 11.5 liters of hot water per minute earned the most positive reviews in this group. The device is equipped with a closed combustion chamber and a modulating burner. The efficiency of the device is 93%, power is from 8 to 24 kW.

Second place in the ranking is occupied by the Italian Baxi Main Four 240 F, capable of preparing 13.7 liters of hot water per minute. Baxi gas wall heating boilers are equipped with a closed chamber. The devices have traction control sensors, a thermostat to prevent water overheating, and protection against freezing and scale.

In third place is the German Bosch ZWA 24-2A with an efficiency of 95% and a water heating rate of 11.4 liters per minute. The device easily copes with servicing a house with an area of ​​up to 240 square meters. meters. The compact boiler is equipped with a three-stage circulation pump and an eight-liter expansion tank.

The Neva Lux 7218 double-circuit gas boiler was not included in the top ten, but it can be noted as one of the most affordable devices. The device is equipped with a biothermal heat exchanger, modulated burner, electronically controlled and LCD display. The domestic boiler is aimed at heating a house with an area of ​​up to 180 square meters. meters.

Five leading manufacturers of wall-mounted water heating boilers

The manufacturer plays an important role in the selection of boiler equipment. 70% of consumers are willing to overpay for a brand if its name is associated with product quality.

The first position in the customer trust rating is occupied by Viessmann - a reputable German manufacturer energy saving equipment. Wisman condensing wall-mounted gas heating boilers are equipped with a simulated burner that maintains combustion when the gas pressure is insufficient.

In second place is Protherm, a manufacturer of high-quality and functional equipment at an affordable price. The range of heat generators of this Slovak brand includes several lines of devices with open and closed combustion chambers and a wide power range.

In third place in the ranking of wall-mounted gas boilers is the leading European manufacturer of equipment for boiler rooms, Wolf. The German company's assortment includes models with different combustion chamber designs, with built-in heat exchangers for hot water and the ability to connect a boiler.

The fourth place went to the German leader Buderus. The Logamax series of wall-mounted boilers is aimed at Russian consumers and is suitable for operation under conditions of gas and water pressure differences.

The top five most popular manufacturers among Russian users is closed by the Italian company BAXI, whose product range includes single-circuit and double-circuit wall-mounted gas heating boilers, including economical condensing boilers.

The most attractive in price

Wall-mounted gas heating boilers domestic production recognized as the most affordable in the line functional models. Among Russian manufacturers EPO “Signal” is in the lead, its assortment includes 4 modifications of double-circuit devices of the Angels series. Angels boilers are equipped with a burner with electronic ignition and an automatic ionization-type flame control system.

In the middle price range are Korean wall-mounted gas heating boilers of the Navien brand, represented by groups of high-quality double-circuit devices with a separate and coaxial smoke removal system, operating uninterruptedly under conditions of low and varying gas and water pressure.

Wall-mounted model NAVIEN DELUXE

Daewoo is another Korean giant that supplies the market with inexpensive atmospheric models and economical boilers with a closed combustion chamber. For ease of control, the devices are supplemented remote controls and liquid crystal indicators.

The assessment of a group of consumers may not always coincide with personal opinion, so we recommend considering not only the models that received the most votes, but also other devices from well-known manufacturers, as well as new products that have not managed to win the trust of customers. In order not to make a mistake with the choice of durable equipment, it makes sense to seek help from a specialist who will take into account the needs of the family and real possibilities existing system heating.

Choosing the best boilers - rating of double-circuit wall-mounted gas boilers

With the start of the heating season, the owners country houses The question often arises about which heating boiler is worth purchasing. This article is devoted to an overview of the most popular double-circuit gas boilers. The rating of double-circuit wall-mounted gas boilers was compiled for wall-mounted models from Baxi, Protherm and Navien.
We considered models that were similar in price category and technical characteristics with a power of about 20 kW and these were the following models: Main Four 24 F (Baksi), Gepard MTV 23 (Proterm) and Ace 24k (Navien).

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. Models are assembled and parts are produced in the brand’s homeland 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 produces boilers on its own territory; components are produced in Slovakia and Germany. The range of models imported to Russia is 11-23 kW.

The Korean manufacturer Navien was introduced to the world relatively recently, but thanks to 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 range of models with a power of 10-40 kW is supplied to Russia.

Design of compared models

The boiler from Baksi is a boiler based on a bithermic heat exchanger and the ability to automatically switch to DHW supply mode. The design includes a circulation pump, expansion tank volume 6 liters, safety sensors. All connections are cast from copper. The coolant is heated by a heat exchanger alternately in 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 to switch operating modes. It is also equipped with a German circulation pump and a 5-liter expansion tank, and safety sensors.

The connections, like those of Baksi, are cast from copper. An important difference between this model and the previous one is the presence of a second heat exchanger, which ensures independent heating of water for heating and the hot water system.

The boiler from Navien is also equipped with two independent heat exchangers, but both of them are cast from steel. Let us remember that the previous model had one of the heat exchangers made of copper. A steel heat exchanger is much more reliable than copper.

All built-in equipment - circulation pump, expansion tank, sensors and valves are manufactured directly in South Korea.

Technical parameters of models

The chimney of all the models under consideration is made according to the coaxial scheme. This means that the same pipe has two compartments, through one of which air is introduced into the boiler, and through the other, exhaust gases are removed.

Dimensions of the tested models (HxWxD, cm):

• Baksi 73x40x29.9
• Proterm 74.2x44x26.5
• Navien 72.2x44x26.5

Heating capacity of models (kW):

• Baxi from 9.3 to 24
• Proterm from 9.0 to 24
• Navien from 9.3 to 24

Volume of produced hot water (l/min)

All models are capable of heating an area of ​​up to 220 m2.

Model functionality

To compile a rating of double-circuit wall-mounted gas boilers, all compared boilers have the ability to adjust the burner and the function of maintaining the temperature in a separate heating circuit. In addition, all models have frost protection.

Models from Baksi and Proterm provide the ability to connect a room temperature sensor and an outside temperature sensor, thanks to which you can implement the climate control function.

Baksi, unlike other models, has a “warm floors” mode, and the Navien model has a remote control unit. In addition, the Navien boiler is protected from power surges.

Cost of models

Protherm 600 euros

Navien 500 euros.

Having analyzed the parameters of the boilers according to the indicated parameters, it is easy to conclude that the rating of gas boilers was distributed as follows:

3rd place. Baxi Main Four 24 F

2nd place. Proterm Gepard MTV 23

1 place. Navien Ace 24k

The best gas boilers for heating a private house, cottage, bathhouse and apartment

From this article you will learn which gas boilers are the best in their classes. The material will present the leaders, both among double-circuit and single-circuit devices, and also provide the optimal options for boilers for different rooms– houses, apartments, cottages and baths.

Which brand of gas boiler is best to buy?

The modern heating boiler market offers consumers devices in the most extreme price categories - from cheap Chinese equipment of dubious quality to expensive branded boilers with turbocharged combustion chambers and other bells and whistles.

Among the manufacturers, it makes sense to note the following companies: Baxi, Protherm, Buderus, Vaillant, Bosch, Viessmann and Ferroli. These are serious companies that have been present on the market for a long time, the quality of their products has been tested by hundreds of thousands of customers.

The best manufacturer of gas boilers from Russia is the Irbis company, whose products can be considered as a budget option. Although domestically produced boilers lose competition to foreign devices in terms of performance characteristics and ease of use, they perform their direct functions quite adequately.

Rating of the best gas boilers

There are several types of gas boilers, and therefore, when choosing a model for your home, you need to know exactly what you need. Let's briefly go through the classification of each type of heating equipment:

Single-circuit and double-circuit

Single-circuit gas boilers in the basic configuration are used exclusively for heating the room, while double-circuit gas boilers, in addition to heating the home, are also responsible for supplying hot water.

It is worth noting that, if desired, you can additionally purchase a boiler for a single-circuit boiler, and then it will be able to perform all the functions of a double-circuit boiler.

In terms of design features, these types have significant differences: double-circuit boilers are much more compact, which makes them an ideal option for rooms with limited free space, but they are also more demanding in terms of operating conditions. A double-circuit boiler heats running water, and in order for the hot water system to automatically turn on, the flow of incoming liquid must have high pressure, as a result of which saving hot water is practically impossible.

Also, double-circuit boilers are not the best solution for large rooms, where water intake devices - taps, showers, etc., are very distant from the boiler itself. This is due to the fact that a heating system based on a double circuit cannot be equipped with an additional circulation pump.

Single-circuit boilers also have their own characteristics, including large sizes and labor-intensive installation. When using a boiler, systems based on single-circuit boilers can be supplemented with circulation pumps to supply hot water to several water intake points, however, the efficiency of such a system is limited by the volume of the boiler.
It is also worth noting that the total cost of a system consisting of a single-circuit boiler and a boiler is higher than the price of a double-circuit boiler.

Floor and wall

Everything is simple here - floor-standing boilers are installed exclusively on the floor - they have much larger dimensions and power than wall-mounted counterparts, which make sense to use only in cases of limited free space.

As a rule, the power of most wall-mounted boilers is limited to 35 kW, as they have a copper heat exchanger that cannot withstand high temperatures.

Floor-standing boilers are the best option for heating rooms with an area of ​​150 to 600 sq.m. Depending on the configuration, floor-standing boilers can have either an atmospheric or a turbocharged burner. A distinctive feature of atmospheric burners is endurance, noiselessness and high price, while boilers with turbocharged burners have an order of magnitude greater efficiency, but are also significantly more expensive.

The best gas floor heating boilers

Having dealt with the classification of modern gas boilers, we move on to compiling a rating. To do this, we analyzed numerous reviews from owners of a wide variety of boilers and identified the best models in each class of heating equipment.

Single-circuit gas heating boilers

Let's start with single-circuit units, since they are the most popular types of gas boilers.
