Condensing theory - How do condensing boilers add

In the graph below you can see the dilution of the CO2 created by the excess air. Air is 20.9% O2, 78% Nitrogen and about 1% other gases. Because the air is only 1 5th oxygen the boiler will have to add 4 times the amount of other unrequired gases (mainly nitrogen) to the combustion, to obtain a relatively small amount of excess O2.

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.
