How to choose a boiler for heating a private house?

Today, the market is full of various heating boilers, each with its own advantages and disadvantages. You need to study all the options to make the right choice.

Choosing a boiler for heating a house – basic steps

How to make the right choice and where to start? A boiler is the beating heart of your future home, which will help you not freeze even in the most severe winter.

Its main task is to heat the coolant, which will move through the pipes, and transfer heat through radiators. The entire heating system depends on the correct operation of the boiler, this also applies to hot water.

The main selection criteria that will help break down heating boilers into groups:
  • Type of fuel;
  • Power;
  • Method and place of installation;
  • Type of work;
  • Price.

Variety of fuel in heating boilers

There are four main types of fuel that are used to heat a home.

  • Gas boiler. It can be natural or liquefied and is the cheapest option. All that is needed is to conduct the main gas and you are ready, you can buy a gas boiler. Each model can operate without the main gas source using cylinders;
  • Wood and coal boiler. For heating, wood is used, variations of coal, coke, briquettes or wood chips. The disadvantage of such a boiler is that it is constantly necessary to monitor and replenish fuel, that is, to throw firewood. As a result, we get a non-automated heating option that is independent of electricity;
  • Electric boiler. Such a boiler will be the cheapest, although the fuel source itself is expensive. To install such a system nearby must be electrical power. This variation of the boiler is the most neutral, without pronounced minuses or pluses;
  • Diesel boiler. The liquid fuel boiler is fully automated, this is a huge plus for any host. Diesel is an expensive option but costs less electricity. Boilers of this group are universal, can become gas at any time and do not depend on the main. Another advantage is the absence of smell or noise during the operation of a modern diesel boiler.

Choosing the power of a heating boiler for a home

The power of the future heating boiler must be selected according to one criterion – the future area of ​​the room in which it will be installed. The larger it is, the more powerful the boiler is needed. It is also worth remembering about heat leakage, the so-called heat loss effect. The heat always disappears through open windows or doors, this factor depends on the insulation of the building itself. For this reason, the boiler must have a power reserve.

The power parameter is measured in kilowatts, 1 kW can heat approximately 10 squares. Let’s make an approximate calculation, imagine that your house has 200 squares. We get:

200 m2 = 20 kW boiler power + 15%, from which we get an approximate power reserve of 23 kilowatts.

The purchased heating boiler must have a capacity of at least 23 kW. Keep in mind that this does not affect fuel consumption per se, the boiler always uses only the right amount of energy. But in winter you will get maximum heat and will not freeze. The boiler will not work at maximum power since it has a reserve, which means that its operation period will increase by several years.

Choose a boiler according to the installation method and location

  1. Outdoor version. Such a boiler is always placed in a separate room due to several requirements when installing it. This also applies to several nuances and the location of the necessary things, for example, an expansion tank, pump, pipes, various taps, and fittings. For this option, you need a boiler room;
  2. Wall-mounted version. Most often it is a ready-made mini-boiler room. The casing is equipped in advance with all the necessary elements so that the boiler can work. This applies to the expansion tank, pumps, thermometer and pressure gauge, as well as additional components. The wall-mounted boiler is very popular in recent years, it will help you save space in the house and does not require a separate room. It is also worth highlighting its favorable price, the service life does not exceed ten years.

Choose a boiler by type of work

The main criterion is the differences in the working type. You should not add fuel or location to this characteristic, it does not matter in this case. You can purchase a boiler with the following type of work:

  1. Single-circuit boiler. Such a boiler is intended only for heating a private house. It can heat water for a shower, washing dishes or a car, that is, it fully provides all rooms with hot water. This requires several additional nodes and the connection of various devices, for example, an indirect heating boiler and a pair of pumps. Such a boiler needs a separate room since it has an impressive size;
  2. Double-circuit boiler. Recently, this version of the boiler is one of the most popular, it can both heat the house and give the owner a hot water supply. A knot is placed in advance inside the housing; it, in turn, can heat water for domestic purposes. This fact will save a lot of space since it does not require additional equipment. Such a boiler is suitable for a small country house or private apartment, where no more than three people live;
  3. Chimney boiler. Such a boiler always has an open combustion chamber through which a house is sold when burning fuel, that is, the main combustion product. It should be discharged through a chimney, which must be placed separately, always above the roof of the house itself. Such a boiler needs a natural draft and the presence of a chimney, or it simply will not be able to work. It is also worth remembering about the installation of ventilation because such a boiler will take atmospheric air to work directly from the room. Almost always installed in a separate boiler room;
  4. Chimneyless boiler. Such a boiler has a closed combustion chamber, to which a special fan or a pressurized burner is always connected. This eliminates the construction of the chimney, although by the rules of use it is still needed. The differences are in its installation, it can be installed in a horizontal position and can be led out through the wall. The main advantage of such boilers is the lack of forced ventilation as such. If you did not foresee a chimney in advance, then choosing just such a variant will save on the construction of a separate stationary chimney.

Total

In conclusion, I want to say that the price is a too individual indicator to list possible options. Boilers can be arranged by type of fuel, where the first option is the cheapest:

  1. Electric boiler;
  2. Solid fuel boiler;
  3. A gas boiler;
  4. Oil boiler;
  5. Combined, that is, a universal boiler.

The given sequence is not always true, because the cost may depend on the performance of the model, material, automation, and life.
