Condensing technology is used in modern combi boilers to efficiently heat the system water by recovering latent heat from flue gases. A gas burner in the combi boiler is activated when you need heating or hot water. The heat from the flame is transported to the primary circuit via the main heat exchanger, where it is moved either directly to the radiators or via a plate heat exchanger to your hot water taps.

How long does a combi boiler usually last?

Depending on the model and how often they are serviced, combi boilers can last anywhere from 10 to 15 years. Regular boiler maintenance can significantly extend the life of a combi boiler.

How much does it cost to install a combi boiler?
