Condensing Oil Boiler - Commercial Oil Boiler - 15k

High efficiency Condensing Oil Boiler. Modern condensing oil boilers are designed to use virtually all of the energy content of the oil – often referred to as the higher heating value. Compared to standard boiler technology, oil condensing boilers also recover the heat of condensation of the water vapour contained in the exhaust flue gas.

condensing water boiler - Steam Boilers For Sushi-koi.

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
