When designing a private house, one of the crucial points is the choice of the type of heating. Since the expanses of our country are endless, the climate in different regions is significantly different. Therefore, the choice of a boiler for a heating system has to be approached taking into account weather conditions and the availability of a certain energy source. An important factor for many homeowners is the safety of operation, this primarily concerns buildings where children or old people are left alone for a long time. Today the market offers a wide range of boilers, they seriously differ in price and technical characteristics. The recommendations of our experts will help you choose the most suitable boiler for each specific home.

How to choose an economical boiler

Boiler type. Currently, several types of boilers are popular in Russia. The choice depends on the characteristics of each region.

  1. If a gas line passes through a settlement, then most homeowners try to connect to it. Blue fuel remains the cheapest source of thermal energy. Gas boilers are distinguished by a higher price, and consumers spend a lot of energy and nerves when designing, laying a gas line, connecting and subsequent maintenance. But ultimately the cost of heating will be the lowest.
  2. Solid fuel boilers, like devices operating on diesel fuel, have one significant drawback. They require the constant presence of an adult. In addition, a lot of trouble arises with the delivery of solid and liquid fuel, its storage and subsequent disposal of combustion products.
  3. Electricity allows you to create the safest and most environmentally friendly heating system. At the same time, it will organically fit into the concept of “smart home”; you can control and monitor the electric boiler remotely. The only drawback of this type of energy is the high price.

The choice of thermal power. One of the main parameters of any boiler is its heat output. Knowing the area of ​​your house, it is not difficult to find a suitable model for yourself. Experts advise sticking to a simple formula. For comfortable heating of a room with a height of 3 m and an area of ​​10 sq. m it is necessary to spend 1 kW of thermal energy. So for a house with a total area of ​​120 sq. m, a boiler with a maximum heat output of 12 kW is suitable. But it is better to have a device with a small margin of 10-15 kW. When buying a boiler, you should pay attention to the efficiency of the device. The higher this value, the less power reserve is required.

Equipment. Many consumers focus on cost when choosing a boiler. Some manufacturers are tricky, they offer a low price due to the minimum configuration. Components such as the circulating pump and expansion tank have a significant impact on pricing.

Additional options. To make the operation of the heating boiler comfortable and carefree, modern appliances are equipped with a whole range of options.

  1. Self-diagnostics helps to identify problems in a timely manner, which will reduce the cost of repairing the device.
  2. Electronic control minimizes homeowners' attention to the heating system. Having set the device to a certain temperature range, you can stay away from the boiler for weeks.
  3. Overheating and frost protection will prevent damage to the heating main and the boiler in case of force majeure.

Dimensions and weight. Not all houses have spacious boiler rooms. Some homeowners prefer to buy compact and lightweight wall-mounted models. This point should also be taken into account before buying by making the simplest measurements of the selected place for the boiler.

We have selected 11 of the most economical boilers for review. All of them are sold in the Russian retail network. When allocating seats, the editorial board of the journal took into account the opinion of the expert community and the feedback from domestic consumers.
