The flue boiler is Charnwood’s latest home heating innovation. This revolutionary stove addition replaces the first few feet of the standard flue rising from the top of the stove and utilises the excess heat from the appliance that would otherwise be lost. In addition to this because the boiler is external the stove maintains its high clean-burn combustion efficiency. Depending on the size of stove and subsequent flue boiler, outputs of between 1.8 and 3.4 kW can be achieved with minimal effect on the nominal output of the stove. This can provide sufficient heat for domestic hot water and up to 3 radiators. The flue boiler comes in 3 sizes to fit all Tor, Cove, Island, C-Series and Countrydry models.
