Using this technique, condensing boilers can reach up to 10-12% more efficiency than a regular gas boiler. Which means that they have an overall efficiency of 90% AFUE. This is almost the same as a modern high-efficiency furnace or electric boiler. Our line of condensing boiler systems are much better than regular boilers.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
