Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

How do heat exchangers work? - Explain that Stuff

May 04, 2021 · Hot water is piped through it from a gas central heating boiler, giving up some of its heat to the air in the room in the process and returning to the boiler for more. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing.
