Looking at the instructions to the boiler, you can find out that the efficiency at it equals, for example, 95%. However, this does not mean that the boiler will achieve such efficiency often during operation.
On the contrary, this will be extremely rare, because the maximum stated in the instruction is achieved only when a number of conditions are met.
How to increase the efficiency of the boiler?
Reduce heat loss with outgoing gases toIncrease the efficiency of the boiler. To do this, make sure that the ash and soot do not build up on the heating surfaces, the heat fryers. Make sure that the surface of the pipes, through which the coolant flows, is not covered with scum, for which the coolant should not be changed frequently. If it is drained every month, fuel consumption will increase. Eliminate the appearance in the boiler of excess air, which takes out of the boiler all the heat through the chimney. To achieve this, it is necessary to install a traction limiter on the chimney. It costs not more than 3000 rubles, and you can save a lot of money on it.
Limiter of traction is installed on the chimneyBoiler. The main purpose of this device is to ensure a constant pressure at the outlet of the gases from the boiler. There are also turbulators, which are installed on the fire tubes of the boiler. They are several times more expensive than the traction restrictor, but they help increase the heat exchange between the hot chimneys that go inside the boiler and the coolant behind the wall.
Maximum exclude chemical underburning of fuelAnd ensure the necessary coefficient of excess air inside the boiler. This factor is 1.2-1.3 for solid fuel and 1.05-1.15 for liquid. To achieve this: install the traction limiter, which was already mentioned above, on the chimney of the boiler. The boiler must be purchased exclusively in a specialized organization, which necessarily and with the help of expensive equipment adjusts the necessary volume of air that passes through the boiler. Let it requires an additional fee, but in the future you will save a lot of money on fuel. It is advisable that a lambda probe is installed on your boiler, which helps maintain the necessary balance of air and fuel in the boiler burner.
Maximally eliminate mechanical underfireFuel. To achieve this, buy low ash fuel. In case you are drowning pellets, the ash content of fuel should not be more than 0,7%. If you are drowned in coal, choose coal with the least ash content, despite the fact that it costs more. Let the cost be 2 times more than for fuel with high ash content. Having saved on fuel, you will spend more money on repairs and low efficiency of your boiler.
