The diagram below shows how central heating system in a house works.
The diagram represents the process of central heating systems in a house.
Overall, cold water flows into the house and this water, and then passes through four stages of processes before being ready for use in the radiators in order to heat the houses.
Looking in details, the cold water comes from the outside firstly and then this flows in by passing the pipes. This cold water is immediately placed on a storage tank before it heated up by a boiler, which is used by gas or oil. This boiler is controlled by a pump and the water then is distributed to four radiators in a house through small tubes. After circulating between radiators heating up the house, the left over water flows back into a storage tank by passing a gas or oil boiler. Then, this water is divided into two ways; either to go to the water tank for any overflow of water in a house or any hot water is placing in taps.
