The heated water is then pumped through to heat your home and domestic hot water. In condensing (high-efficiency) boilers a second, or larger primary, heat exchanger removes even more of the heat from the flue gases. This pre-warms the water coming back into the boiler, so you burn less gas to heat the water up, making it more efficient.
