of the flue gases can be reduced to below 60ºC (the point at which the water vapour in the flue gases starts to condense). This releases the latent heat from the water vapour, significantly boosting the boiler's efficiency. Building regulations now require boiler efficiency to be expressed as a seasonal figure, to reflect the efficiency
