12 best wall mounted gas boilers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

So far, blue fuel in Russia remains the most affordable raw material for generating heat. Therefore, gas boilers are very popular in the domestic market. Distinctive features of these heating devices are reliability, durability, ease of control, ease of maintenance. Since many modern models are equipped with electronic control, the consumer needs to bring a 220 V outlet to the installation site and purchase a voltage stabilizer. The recommendations of our experts will help potential buyers find their model in the variety of gas boilers.

Recommendations for choosing a wall-mounted gas boiler

Design features. The search for a suitable heater follows from its design.

1. Single-circuit models have a narrow focus, heating the coolant in the heating system. They are simple and affordable.
2. Double-circuit devices look more complicated. They are able to solve two important tasks at once: to warm the house and provide residents with hot water. Such a boiler is more expensive, but in the end the consumer will be able to save money.

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

1. Modern convection models burn gas efficiently enough, their efficiency reaches 92-93%.
2. Condensing boilers work about 12-17% more efficiently, therefore the efficiency reaches 106-109%.

Equipment. Many users, having bought cheap gas boilers, faced additional financial costs. Therefore, when choosing a model, it is necessary to pay attention to the presence of a circulation pump and an expansion tank in the kit. Also, it will not be superfluous to consult with installers about air ducts and a chimney.

Safety. Blue fuel, despite its environmental friendliness, is fraught with danger for the residents of the house. The gas has a toxic effect on humans, and in case of an accidental spark, the gas mixture can explode. The most important safety elements of the boiler are:

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

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

Heat exchanger material. The heat exchanger works in the most aggressive environment. The outer wall is exposed to high temperatures, and the heat carrier (water or antifreeze) acts destructively inside. Heat exchangers made of copper, aluminum and stainless steel are considered the most resistant.

We have selected 12 of the best wall-mounted gas boilers for review. All of them are sold in the Russian trade network. When allocating seats, the editors of exprtology relied on expert opinions, taking into account user reviews. This review is based on the analysis of the technical characteristics of the boilers on the RankQuality.com website.
