Higher efficiency thanks to condensing boiler technology
Condensing technology
Pellet boilers with condensing technology also utilise the residual heat contained in flue gases. This additional heat recovery allows more of the energy contained in the fuel to be used for heating, helping to reduce pellet consumption compared to conventional pellet boilers without condensing technology.
How does condensing technology work?
In the normal combustion of pellets, water accrues in vapour form in the flue gas and escapes unused through the chimney. However, it is precisely this water vapour that is cooled down below the condensation temperature with condensing technology. This process produces liquid condensate that in turn releases heat during the transformation. This additional heat gain is fed into the heating system, where it can be reused.
