The best double-circuit condensing boilers

Condensing boilers use the energy released during condensation to heat the return. A short time after start-up, more than warm water, which allows you to spend less gas on its heating and makes the temperature in the heating circuit even. This helps to save blue fuel, but the price of double-circuit condensing boilers is quite high.

The first position in the rating belongs to a two-circuit condensing model with a maximum power of 30 kW. This is a wall-mounted boiler with a 12 l expansion tank and an electronic control circuit powered by a single-phase network. The equipment of the device includes: overheating protection, gas control, display, auto-ignition, thermometer, on-state indicator, pressure gauge. Buyers in the reviews share that the power range from 4 to 30 kW is practical for future plans to expand the house. While the area is small, you can save and reduce consumption to a minimum, while maintaining heat. When will additional rooms or a garage, the boiler can easily cope with an extended heating circuit.

Our experts liked the double-circuit boiler with its efficiency of 109%, which is superior to other products in the rating. This efficiency is achieved due to the aluminum main heat exchanger, enclosed in a round body with a burner inside.

Attention! This rating is subjective, is not an advertisement and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Many owners of private houses and industrial buildings are switching to heating system using gas as an energy carrier: this is the cheapest and most profitable.
A huge variety of foreign-made boilers of different price ranges is presented on the market, there are gas boilers heating are Russian, the prices of which are more affordable. Let's take a closer look at them and try to understand the proposals of the domestic manufacturer.

The boiler is primarily a functional device, moreover, the acquisition is not cheap. But the most important thing is that with the right choice, it is the boiler that can significantly reduce the costs of its owner, and the number of heating system repairs, the frequency of visits to service centers and the participation of residents in the maintenance of heating equipment depend solely on the right choice.

Will the boiler start at the beginning of the season, will it have to be lit manually and how often, will it provide the greatest possible savings on heating, will the boiler lead to air pollution and the room in which it was installed, will it lose its appearance over time and how long will it last - it all depends on right choice boiler suitable for a particular room. Moreover, you can avoid all the above inconveniences without overpaying, but only competently choosing heating equipment.

When choosing a gas boiler, you usually pay attention to the following characteristics:

Boilers are classified according to installation method, functionality and exhaust gas outlet. According to the installation method, boilers are wall-mounted and floor-standing, according to the type of functionality, single- and double-circuit boilers, according to the method of gas removal - with a closed and open combustion chamber.

Floor-standing boilers are in the greatest demand: they allow you to heat a large area, are reliable and have a wide power range - 11–68 kW.

Russian manufacturers have learned to produce floor-standing boilers adapted to our operating conditions and able to compete with imported models, therefore, having bought a floor-standing gas boiler Russian production, you can reduce start-up costs and get a completely reliable and in no way inferior to foreign, heating device.

The storage unit can hold up to two hundred liters of water. Thus, if you buy a Russian-made double-circuit floor-standing gas boiler, two tasks are solved at once - heating and hot water supply. Sometimes it is advisable to purchase a boiler for a single-circuit boiler, then it will work on the principle of a double-circuit one. However, double-circuit boilers are much more compact, so they are better suited for rooms with a limited area. But they have a requirement: the flow of incoming water must be under high pressure. In addition, they are not suitable in cases where the bathroom is located at a great distance from the boiler itself.

Closed and open combustion chamber

As for the type of combustion chamber - an open chamber uses the air of the room, and exhausts the exhaust gas through the chimney, a closed one (turbo) contains fans that take in air from the outside and send combustion products there. Boilers with open type combustions work on the principle of gas burners, heat up themselves, warm the air around them (hence the lower efficiency), require some distance from flammable objects. Turbo models are considered more economical and safer.

Among domestic models, you can find all the listed types of floor boilers, choosing according to the necessary parameters. Experts believe that modern Russian-made gas floor-standing boilers, even if they do not have highly competitive technical and operational characteristics, perform their main functions properly.

Popular Russian manufacturers of heating equipment

Choosing heating equipment affordable price, it is reasonable to proceed from considerations of individual needs, focusing not only on the brand. In general, floor heating reviews are increasingly positive, perhaps this is due to a decrease in purchasing power, or maybe our compatriots have begun to trust local manufacturers more and have given themselves the opportunity to evaluate Russian equipment.

Domestic gas boilers have a number of advantages for the Russian buyer:

• reasonable price;
• good service base;
• optimum efficiency.

Among the shortcomings of Russian boilers are:

1. large weight and dimensions;
2. inability to regulate temperature;
3. often outdated design.

Zhukovsky Machine-Building Plant

The plant has been producing heating equipment for over 40 years. The company presents boilers of three series (types) on the market: Economy, Universal and Comfort. Depending on the type, Zhukovsky gas boilers are equipped with imported automation or the development of their own engineers. Automation performs disconnection / connection of the burner, monitoring the temperature in the heating system, monitors the readings of safety sensors and turns off the gas supply to the boiler in the event of a potentially dangerous situation. All ZhMZ models do not require an electrical connection. Among them there are both double-circuit (AKGV) and single-circuit models (AOGV).

Floor-standing gas boilers ZhMZ of the Economy series are equipped with an atmospheric burner, equipped with emergency sensors thrust, easy to adjust, have a high efficiency. However, these models do not provide protection against overheating, which requires a more accurate calculation of the power when purchasing the boiler, as well as periodic manual ignition of the igniter in cases where the protection is triggered. In addition, economy-type appliances require a mandatory annual maintenance procedure before the start of the season.

But for Zhukovsky gas floor heating boilers, the price is so attractive that these minor inconveniences can be ignored. In addition, the listed maintenance features apply only to the Economy series boilers. The automation of the Universal and Comfort models is more perfect (Italian and German production, respectively). These models do not demand service, are reliable and not capricious.

The price is one of the main advantages of Zhukovsky heating devices, but not the only one. In addition to low cost, they have a high efficiency (80 - 92%), a high degree of reliability and have long term operation. The standards of the plant, which, by the way, also produces aviation special equipment, are conducive to confidence in the strength and long service life of the heating equipment produced here. If you need a Russian-made outdoor gas boiler, the price of which will be minimal, and the work will be stable, perhaps you should take a closer look at the Zhukovsky models.

Borinsky

Like Zhukovsky, this plant has been producing heating equipment for a long time - more than 20 years. The enterprise produces single-circuit and double-circuit boilers with the usual AOGV and AKGV markings, as well as boilers of its own design of the ISHMA series. All of them are equipped with imported automation, almost all models are non-volatile, have a relatively modern design and low price.

The reviews on Borinsk gas boilers are not bad, they speak especially warmly about the models of the IShMA series - they are additionally equipped with gas pressure sensors, providing devices with an increased level of automation of equipment operation and help to reduce specific gas consumption by about 15-20%. TO important advantage Borin heating appliances can be attributed to the durability of the budget series AOGV and AKGV due to a reliable cast-iron heat exchanger. True, this affects the cost.

For comparison, the heat exchangers of ZhMZ boilers are made of steel, so they are cheaper. Due to cast iron elements, some models of Borin boilers are also heavy.

For those who are looking for floor-standing Russian gas heating boilers, which are particularly durable, it is worth considering models from Borinskoye OJSC.

In general, if we compare boilers according to the material of the heat exchanger, then we should take into account some comparative characteristics cast iron and steel models.

Steel heat exchangers:

• cheaper than cast iron
• easier to transport and install;
• slightly less durable than cast iron.

Modern steel grades correct operation provide a service life of up to 30 years.

Cast iron heat exchangers:

It should be borne in mind that prices for Russian-made floor-standing gas boilers also partly depend on the material of the heat exchanger.

If you need to buy a single-circuit floor-standing gas boiler that would look attractive, you should also consider Borinsky's proposals. The boilers are covered with polymer enamel, which gives them an attractive appearance: they will fit well into a modern interior and will look quite impressive. But there are also disadvantages: increased sensitivity to fuel quality and susceptibility to corrosion.

In general, the heating equipment of Borinsky is perhaps even the most reliable domestic gas floor heating boilers, the prices of which are significantly lower than similar offers from the foreign market. All models of Borinsky boilers are ideally suited for operation in Russia and are characterized by high, up to 90%, efficiency.

"Signal"

Engels Plant of Heating Equipment "Signal" in Lately gain popularity. His gas boiler Signal KOV-10ST and other models collect good reviews, given the optimal price / quality ratio, however, the installation of Signal boilers can be difficult due to the discrepancy in connector standards. Reviews for this gas boiler Signal are generally positive, as well as for other models of the manufacturer. They attract mainly low price.

There are single- and double-circuit models on the market, imported automation, in operation - moderately capricious.

For many who decide to buy a floor-standing gas boiler, the price often becomes the main selection criterion, but on Russian market such a variety of heating equipment manufactured in Russia and the CIS is presented at a relatively equal and affordable price that it is possible to choose a model in the same price range that meets the requirements for all key parameters.

Many became interested in small-sized and attractive design boilers "Pechkin" (Taganrog), choosing as the main argument that, for example, the gas boiler Pechkin KSG-10 is small-sized and equipped autonomous system water heating continuous action. And someone chooses a gas floor boiler Hephaestus, which has an original water-tube heat exchanger design based on the “Russian stove” principle, which ensures quick and efficient heating of the entire heating system.

You can buy a gas boiler ThermoBar (Ukraine) with a multi-section atmospheric burner that ensures the purity of the combustion products of the fuel, quiet operation and avoids the accumulation of soot in the combustion chamber even during long-term operation of the device. You can read about other popular gas boilers of Ukrainian production. In addition to the manufacturers mentioned above, the Lemax and Rostovgazapparat enterprises stably occupied their niches.
