The diagram below shows how a central heating
system in a house works.
Summarise the information by selecting
and reporting the main features, and make
comparisons where relevant.
This diagram shows a house's central heating system. It shows that cold water
goes into a tank, and then goes into a boiler and then goes through pipes to
radiators and taps.
Cold water goes into the house and goes into a water storage tank at the top
of the house. Then it goes to the boiler, at the bottom of the house. This boiler,
which can use gas or oil, heats the water. Some of the hot water goes to a storage
tank and from here it can go to taps to provide the hot water for the house. Also
some cold water goes from the tank to the taps.
Other hot water goes around the house by being pumped through pipes and
goes into radiators in different rooms. The water goes through hot water radiators
in small tubes, so the radiators get hot and this heats the house.
After going through the pipes and radiators the water is cold, so it goes to the
boiler again to be heated again and then go around the house again.
