Condensing boiler

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.

Comparing Indirect vs Direct hot water

Explaining direct and indirect fired units. Direct fired units such as Dorchester water heaters for hot water generation have an integral gas or oil burner that directly heats the water in its storage cylinder by supplying hot gases through one or more of its heat exchanger fire tubes within the cylinder which then transfers heat to the surrounding water.
