　　The boiler, which is fuelled by gas or oil, heats up the water as it passes through it. The hot water is then pumped round the house through a system of pipes and flows into the radiators, located in different rooms. The water circulates through the radiators, which have small tubes inside them to help distribute the heat, and this warms each of the rooms. Some of the water is directed to the taps to provide hot water for the house.
