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.Get Price
The main difference to EN 12952-15 is that as input the higher heating value of fuel is used. Therefore one needs to account as loss the latent heat of water exiting with the flue gas. Numerical values of efficiency derived from ASME PTC-4 are thus significantly lower than from EN 12952-15. In practice the core of the calculations is fairly Get Price
