13 best wall mounted gas boilers

*Editor’s review of the best upright vacuum cleaners. About the selection criteria. This material is subjective, it is not an advertisement and does not serve as a guide to purchase. Consultation with a specialist is necessary before purchase.

While blue fuel in Russia is still the most available raw material for thermal energy. Therefore, gas boilers are very popular in the domestic market. The distinctive features of these heating devices are reliability, durability, ease of operation, easy maintenance. Since many of today’s models are equipped with electronic control, the consumer is required to bring the place of installation of 220 V outlet and buy a voltage regulator. Recommendations of our experts will help potential buyers to find their model in a variety of gas boilers.

Wall mounted gas boiler selection recommendations

Construction features. Search for the right heater should start with its design.

  1. Single-circuit models have a narrow focus, heating the coolant in the heating system. They are characterized by simplicity and affordable price.
  2. The two-circuit devices look more complicated. They can perform two important tasks at once: to warm the house and provide hot water to the occupants. Such a boiler costs more, but in the end the consumer will be able to save.

EFFICIENCY.The efficiency of the gas boiler is determined by the efficiency factor. This indicator is expressed as a percentage, the higher it is, the less loss will be when burning blue fuel.

  1. Modern convection models quite effectively burn gas, their efficiency reaches 92-93%.
  2. Condensing boilers are about 12-17% more efficient, so the efficiency reaches 106-109%.

Accessories. Many users, buying cheap gas boilers, faced with additional financial costs. That is why when choosing a model it is necessary to pay attention to the presence of a circulating pump and an expansion tank. It is also not unreasonable to consult with installers about the ducts and chimney.

Safety.The blue fuel, despite its environmental friendliness, poses a danger to the occupants of the house. The gas has a poisonous effect on humans, and in case of an accidental spark, the gas mixture can explode. The most important elements of the boiler safety are:

  1. gas control;
  2. air vent;
  3. safety valve.

If the boiler is installed in the country, it is worth giving preference to models with protection against freezing, overheating and pump blocking.

The material of the heat exchanger.The most aggressive environment for the heat exchanger. The outer wall is exposed to high temperature, and the inside is destructive to the coolant (water or antifreeze). The most durable heat exchangers made of copper, aluminum and stainless steel.

We selected the 12 best wall hung gas boilers in the review. All of them are sold in the Russian trade network. When assigning the places, the editorial staff of exprtology magazine based on experts’ opinions, taking into account the reviews of users. This review is based on an analysis of technical characteristics of boilers on the RankQua website

However, the electricity here is used essentially only for the operation of the control panel and display.

    The boiler is able to please and some other “chips”, rarely found in competitors. For example, it includes an 8-liter expansion tank. And also the device has at its disposal a circulating pump that allows the coolant to move through the connected pipes and batteries. This means that in addition to this boiler you do not need anything else.

    What are the disadvantages of this model?? Perhaps the complaints can be made only about the cost. The device is very expensive, and therefore not every Expertology reader can afford to buy it.

    Rating: 4.8

    Bosch Condens GC7000iW 24

    One of the most expensive gas boilers among the appropriate consumer status. But it is well worth the effort, especially if you intend to install such a device in a very large private home. The fact that this model can please both with exquisite design and excellent performance. At the same time, the size of the boiler can not be called very large. The same can’t be said about the weight – 43 kg might even scare some people. We recommend that you first check that the wall is capable of carrying the load.

    Almost the entire body of the device is painted white. This enables it to avoid being conspicuous. Against the background of the conditional refrigerator, the boiler is generally lost. The only thing that attracts attention is the miniature control panel, complete with a display. If you want to touch this boiler, you will immediately feel the coolness of the glass, which covers the entire front panel.

    Nominal heat output of this model varies from 3.4 to 25 kW. With it, the water becomes hot almost instantly. It also contributes to higher productivity. Heating is carried out in a closed combustion chamber. It is interesting that you can control the process, including with your smartphone – for this purpose, the gas boiler has received a wireless module. The choice is also provided in terms of fuel – gas can be both natural and liquefied. The first one consumes 2.59 cc. m / h, and the consumption of the second is about 2.2 kg / h.

    At such a cost, it is not surprising that the device has received a quality exhaust fan, which is almost inaudible. For its work, the boiler must be connected to the series 220V. It provides functionality and built-in circulation pump. Of other features of this model can be noted the presence of an expansion tank, the volume of which is brought up to 10 liters. And you can connect the boiler to the underfloor heating – at least it is declared by the manufacturer.

    So expensive gas boiler must be protected in every way. In this respect, the Bosch Condens GC7000iW 24 can only please. It implements protection against freezing – an incredibly important function for Russia. Also, the device is ready to automatically shut off in case of overheating. However, it is unlikely that something like this will happen at least once. There is also an auto-diagnostics. And this model will please you with the presence of a pressure gauge, gas control and modulation of flame.

    Perhaps, it is almost ideal single-circuit gas boiler. If its price was at least one and a half times lower – the device could become a real hit in our latitudes.


    • It is possible to control from a smartphone;
    • Many safety features;
    • Elegant design;
    • High heat output;
    • Large expansion tank;
    • There is a circulation pump;
    • Excellent performance.


    • Astronomical price tag;
    • Great weight.
