Experiencing Costly Heating Bills? It is estimated that on average, a boiler can be as low as 60% efficient, which means only 60 pence of every pound spent on heating is being put to good use.

Mostly all new boilers are Condensed, which results in a large improvement in efficiency by using waste heat in flue gases to pre-heat cold water entering the boiler.
