Condensing Boilers

An oil condensing boiler also recovers the heat contained in the water vapour of the flue gases, heat that a conventional boiler loses up the chimney. It therefore needs less oil for the same heating, especially when water returns from the radiators at a low temperature.

Here you will find Grant Vortex boilers: Boilerhouse models for a boiler room or indoor space, and Combi models that also provide domestic hot water, in Low NOx versions. Installation requires a condensate drain and a flue suitable for condensing boilers.
