Understanding Wood Boiler Efficiency and EPA Ratings

Oct 26, 2018· Oil and gas boiler efficiency is somewhat comparable to EPA accepted wood fueled boiler efficiency ratings, but the comparison is far from perfect. Due to the more consistent nature of the wood pellet fuel and the near complete elimination of human operation, tested wood pellet boiler efficiency will more closely match actual field use than will test results for firewood or wood chip fueled boilers.

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018· The 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.

Condensing boiler - Wikipedia

Condensing boiler. 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.
