*Review of the best according to the editors of expertology.ru. About the selection criteria. This material is subjective in nature, does not constitute advertising and does not serve as a purchase guide. Before purchasing, consultation with a specialist is required.

In many regions of Russia in winter the air temperature drops significantly below zero. Therefore, in houses, workshops and workshops it is impossible to do without heating. Currently, the most popular are closed circulation systems in which water or antifreeze plays the role of coolant. Boilers are used to heat the liquid. Since heating devices cost a lot of money, consumers start choosing from cheap models. Our experts will help you find effective devices among budget boilers.

Recommendations for choosing a heating boiler

Fuel type.

The most important criterion for choosing a boiler is the type of fuel that will be used as an energy source.

1. Natural gas remains the most affordable and convenient option for heating residential buildings and industrial facilities. The gas boiler must be equipped with safety systems to eliminate the possibility of poisoning or explosion if there is a malfunction.
2. In those regions where there is no gas main, solid fuel boilers have to be installed. They can operate on wood, pellets, coke, peat and coal. The only drawback is the impossibility of automating the process. Solid fuel quickly burns out, after which cleaning and subsequent laying of a new batch of firewood is required.
3. Electric boilers are considered the simplest and most environmentally friendly. Modern models can be controlled remotely, but not every electrical network can withstand the load of a powerful heating element. And the cost of electricity is still high in Russia.
4. Liquid fuel boilers are inferior in popularity to gas and solid fuel models. Such devices are quite expensive; in addition, you will have to purchase and bury a large container for storing diesel fuel in the ground.

Thermal power.

All boilers have a certain maximum thermal output. This indicator allows you to select a device taking into account the area of ​​your home or workshop. Experts advise sticking to a simple formula. To heat a room of 10 square meters. m with a ceiling height of 2.5 m requires 1 kW of thermal energy. But since losses are inevitable during heat transfer, it is better to purchase a boiler with a power reserve (15-20%).

Heat exchanger material

. The heat exchanger is most exposed to the aggressive effects of fire and water. Manufacturers use several materials to produce this critical part.

1. The cheapest boilers are equipped with a steel structure. Their service life is limited to several years due to rapid corrosion.
2. Stainless steel heat exchangers are considered more durable. They are not afraid of corrosion, but are expensive.
3. Copper components have good heat transfer and low weight. They are compact, but expensive and susceptible to impact.
4. Cast iron compares favorably with other materials in its corrosion resistance, reliability and durability. Only with uneven heating can the heat exchanger crack.

We have selected 14 of the cheapest boilers for review. You can purchase them in specialized stores in our country. When allocating places, the editors of the expertology magazine relied on the opinions of experts, taking into account the opinions of Russian consumers.

Low power boiler houses

- these are installations for providing facilities with heating and hot water supply with a power of up to approximately 380 kW. Don’t be confused by their supposedly “low” power: they are suitable for industrial and commercial enterprises, factories and farms, effectively heating up to 3400 m2 of space with ceilings up to 2.7 m high.

Usually, either cast iron boilers or steel boilers are installed in low-power modular boiler houses. Also included

includes make-up / circulation pumps and draft systems, and for steam boilers, heat exchangers, pumps for pumping condensate and condensation tanks are additionally installed, as well as a list of auxiliary and additional equipment, which depends on the production requirements and operating conditions of a low-power boiler room.

In Russia, low-power boiler houses are widely used for heating and providing hot water supply to detached buildings. Such boiler houses are very effectively used as an addition to centralized heating, but can also be the only source of heat if it is not necessary to heat a very large area. Their autonomy, ease of assembly and operation, as well as high efficiency have made them a very popular solution both for temporary facilities (for example, concert and fairgrounds, construction sites, etc.) and for permanent ones (new neighborhoods, cottages, private houses, production facilities, offices, public premises “cut off” from central heating mains).

Low-power boiler systems can operate on any type of fuel

: natural and liquefied gas, diesel fuel, electricity, pellets, wood or coal - the choice in this case depends on the possibility or impossibility of supplying electricity or gas to the boiler room, as well as on specific requirements. In this case, the boiler room can be built into a heated room, can be attached, or can be placed separately.

offers its services for the design and construction of low-power boiler houses. The range of our work includes:

• drafting and approval of the project;
• obtaining all necessary permits from government authorities;
• assembly of the boiler room and delivery to the place of work;
• connection and commissioning;
• service maintenance.

Our company has all the necessary certificates and permits, which allows us to guarantee high quality and absolute legality of our activities. We use only tested, proven equipment and work strictly within the framework of the contract with impeccable adherence to terms and conditions.

One-story houses with a boiler room and their features A boiler room in a one-story house - or in a private house - is a complex of thermal equipment designed to provide the premises with heating and hot water. Such boiler houses can be either centralized, that is, provided by city services, or autonomous, which is especially important in situations where there is no centralized service or it is simply unprofitable.

Construction of a fuel facility The fuel facility (liquid fuel warehouse, fuel storage) is intended for receiving, storing and automatically supplying fuel to the boiler room. The construction of a fuel facility is carried out on the basis of a project completed in accordance with current norms and regulations and having a positive Industrial Safety Expertise Conclusion.

What are boiler units Contrary to popular belief, a boiler unit and a boiler installation were not always synonymous. Previously, a boiler unit was a device that combined a firebox, a superheater, an air heater, a water economizer, all kinds of pipelines and fittings into a single system, while “just a boiler” was really just a boiler.

What do you need to know about installing a solid fuel boiler room? Russian climatic conditions require the installation of a boiler in every home and every enterprise without a central heating supply.

Thermal power engineering and investments. Why are there so few investors in the industry? According to domestic energy experts, the industry is going through hard times and needs modernization. But how can it be done without investment? Analysts believe that the thermal power industry is underfunded, and the financial deficit amounts to trillions of rubles.
