Good condensing boilers can attain energy efficiency of 90% or more. Boiler Efficiency Ratings. A boiler's efficiency is measured by annual fuel utilization efficiency (AFUE). This is the ratio of the boiler's annual heat output compared to the total annual fossil fuel energy it consumes.Get Price
If the condensing boiler can run constantly at varying firing rates, then it'll hit that steady-state nirvana almost of the time. The other boiler will cycle on-off which means increased losses until the HX hits its steady state. Plus, the condensing boiler can operate constantly even when the water temps to supply the load are very, very low.Get Price

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
Due to its condensing design, it's capable of recovering a portion of heat from the vapors which could otherwise get wasted. Lastly, electric boilers produce the least amount of noise, not to mention they're quite compact and easy to install.
