What are solid fuel boilers? What to consider when choosing a boiler - Tips + Videos and Photos For a comfortable stay in a private house, you need to maintain the optimum air temperature. Now there are many options for making heating, but many experts recommend stopping at the choice of solid fuel boiler. They are non-volatile and come out more economical than others.

Advantages and disadvantages of using a solid fuel boiler. Let's take a closer look at what the positive aspects of such a boiler are.

Advantages of the boiler

  • - it is not connected to electricity, which saves energy costs;
  • - low cost of the set;
  • What are solid fuel boilers? What to consider when choosing a boiler - Tips + Videos and Photos - installing a solid fuel boiler is quite simple;
  • - installation work can be done on your own;
  • - well suited for those who do not have a gas pipeline and electricity is provided irregularly;
  • - fuel can be purchased at a low cost;

We have listed all the advantages, and now let's see in what are all the disadvantages of a solid fuel boiler for heating a private house:

  • - the fuel is loaded into the boiler by a person, that is, presence is necessary;
  • - difficulties arise in maintaining a constant optimum temperature;
  • - a high degree of fire;
  • - soot accumulates in the chimney, which can be subject to combustion.

Points to consider when choosing a solid fuel boiler

Before choosing a TT, you need to answer a number of the following questions:

  • - what kind of fuel will be better for you to use: coal, wood, peat, peat briquettes;
  • - what do you want to achieve with the installation of TT: heating the house or even heating water.

IMPORTANT! If you want to receive hot water using a boiler, then you need to install a double-circuit boiler, or connect the boiler to a single-circuit boiler.

  • - how often will you use TT boiler? Perhaps you will only have it as a backup source of heating. If you intend to use such a boiler often, then you should take a reliable and durable boiler.

  • - calculate how much boiler power you will need, based on the area of ​​the room, and also take into account how the house is insulated.

Main characteristics of solid fuel boilers

It is necessary to pay attention to the power of the boiler so that the power reserve is 5-10 kW.

IMPORTANT! When calculating the boiler power per heated area, you need to consider with a margin. For example, the area is 100 m 2 boiler power must be at least 12 kW.

Other characteristics that are also worth paying attention to:

  • - the type of fuel used - the cost will depend on what kind of fuel you use heating for the house.

  • - performance - depends on the features of the equipment and the method of boiler combustion;
  • - cost during operation - not only the cost of the boiler itself is taken into account, but also the fuel costs.

Types of boilers, their differences

There are several types of solid fuel boilers:

  • Classic - type of TT, which uses coal and wood as fuel. Fuel loading is done manually. It has the following advantages: many models do not depend on electricity, safety is high, fuel is cheap, easy to use, efficiency is good. Cons: such a boiler is installed in a separate room, you need a place to store fuel (coal, firewood), you need to constantly clean and load.

  • Pyrolysis boilers is a modernized classic boiler. There are two chambers, which are connected by ceramic nozzles. The first chamber is used for firewood, which heats up at high temperatures and turns into coal and gas. The second chamber is needed to receive pyrolysis gas. The advantages of such a boiler: high productivity, the time between loads increases, it can be used together with a boiler, there is an option to automatically control such a boiler.

    Disadvantages: you need a place for firewood and for the location of the boiler, it depends on the electricity, the high price, if the bookmark is incomplete, then the combustion will be unstable.

IMPORTANT! For a pyrolysis boiler, it is important to take into account the moisture content of the wood, it should be no higher than 20%.

  • Pellet - type of solid fuel in which pellets (wood fuel pellets) are used. The difference from the classic one is that in addition to the combustion chamber, this boiler has a bunker, and there is also an automatic fuel supply. Pros: productivity up to 85%, operating time depends on the size of the bunker for automation, there is a sensor that monitors the level of heating inside and a temperature controller.

    Minus: the high cost of such a boiler.

  • Long burning - fuel burns from top to bottom. There are no temperature jumps in such a boiler. Pros: basically all models do not depend on electricity, Optimum performance, fuel burns for a long time, economical use, easy operation, loading in the boiler does not affect efficiency. Cons: space for fuel storage and boiler maintenance is required, high cost.

The solid fuel boiler heat exchanger is made of two materials:

  1. - cast iron is a structure that consists of sections. If a section fails, it can be easily replaced. This option is more convenient for transportation, installation and maintenance. Cast iron can be cleaned less often because it is less susceptible to wet corrosion. Cast iron boilers take longer to heat up than steel ones, but they cool down much more slowly.

    The downside is that the cast iron heat exchanger does not withstand sudden temperature changes.

  2. - steel - construction, which is a one-piece monoblock. Such boilers have an automatic fuel supply, since the steel is resistant to temperature extremes. There is a rapid heating, but also a rapid cooling.

On many forums, you can see disputes over the choice of solid fuel boilers and few people come to a consensus.

How to choose a solid fuel boiler for a private house?

The following are also taken into account when choosing a boiler:

  • - if in your region the cost of coal, firewood is not very high, then purchase universal equipment;
  • - if you have time to constantly load fuel, then you can choose a classic boiler, because it has a low cost and the simplest design;
  • - if you have a very large area for heating, then it is better to take boilers more powerful and more expensive, such as pyrolysis or long-burning boiler;

If your boiler is not the main source for heating, then you can choose a boiler with a steel heat exchanger, if the boiler will work all season without interruption, then it is better with a steel one.
