MoreThe biggest difference between condensing boilers and "conventional", non-condensing boilers is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.

More2020-7-27 · All modern boilers are rated for efficiency under the new European energy label introduced in September 2015. Nearly all modern gas condensing boilers available in the UK get an A rating on this label, so it can be more useful to use the Sedbuk 2009 efficiency rating if you are interested in the minutiae of how one boiler compares to another.
MoreThe other facet contributing to the high efficiency of condensing gas boilers is the combustion air fan can fully modulate its speed as compared to a single stage, full on or off, device found on typical mid-efficiency boilers. This modulation means the blower can adjust its speed to the varying input rates needed during the fall and spring months.
