The power of each boiler, indicated in kilowatts, is declared by the manufacturer and confirmed during tests. This is the maximum value at which the furnace achieves results classifying it as Class 5 when using the fuel recommended by its manufacturer and listed in the operation and maintenance manual. In practice, boilers achieve different power values at home, because heat reception has different characteristics than in the laboratory, so it is better to consult a specialist in this field to choose the right boiler. It is important to choose the right boiler model, depending on the type of chimney, the size of the boiler room and the availability of fuel.When buying a new boiler, you can get financing from the state or municipal program. The problem of smog is becoming so unpleasant every year that in many cities, especially where the concentration of air pollution exceeds acceptable standards, there are programs to co-finance the replacement of old-generation furnaces. This is worth taking advantage of, because when you buy a new boiler, you can get up to 90% money back.
How do I calculate the boiler capacity needed to heat a house?
When replacing a furnace, especially from a charging furnace to a make-up furnace, we face the dilemma of how to choose the right boiler for our home. The boiler's capacity should be such that it provides heated rooms with energy in an amount that allows them to cover heat loss in any weather, even in severe frost, and most often has sufficient reserve for heating hot water into the boiler. The power required to heat a house is determined based on the so-called estimated heat load of the building, which is calculated using an online calculator. Knowing how much heat our house needs is invaluable when upgrading the heating system, replacing the boiler, or repairing the house. The building's heat load calculator we provided also shows what benefits can be achieved by insulating walls, roofs, or replacing windows in a particular building, so we know which jobs are unnecessary and which ones are definitely worth doing.Adjusting the boiler capacity to the load, what causes an incorrectly selected boiler capacity?
When the boiler capacity is too low, it will, of course, not be able to maintain the required temperature in the rooms. In a situation where the boiler capacity is too high in relation to the heat load, boilers operating most of the season with minimal load do not reach their maximum efficiency, i.e. they consume more fuel, as well as wear out and destroy brick chimneys faster [low-temperature corrosion, condensate]. Therefore, buying a device with a rated power greater than the estimated one is also not the best idea.Choosing the type of boiler
Knowing the power requirement, it remains to choose a specific boiler. The choice is wide, you can choose from the point of view of design: boilers with a horizontal or vertical heat exchanger, burner types: reciprocating, retort, gutter, tube, and by type of fuel: wood-fired boilers, coal dust, eco-powder boilers, pellet boilers, etc. Given the ease of operation and fuel prices, eco-pea coal and pellet boilers are the best. They work well in the most difficult climatic conditions. Modern boilers powered by solid fuels (eco-peas, coal dust) and biomass (plant-based fuels, such as grains of cereals, pellets, cherry pits) require minimal maintenance and are cheap to operate.
