The diagram below shows how a central heating system in a house works.
Given is the diagram illustrating the process of a domestic heating system.
It is clear that there are three main stages of the system. Firstly, cold water is put into the house.
At the initial stage of the process, the cold water enters the house and is stored in the water tank in the roof of the house. It continues with water being gone down the boiler which includes gas or oil.
The process is followed by a step called "circulation of hot water to radiators and taps" where hot water is pumped and flowed into the radiators, located in the different rooms. After that, water circulates through the radiators, which have small tubes inside them to help distribute the heat, and this warms each of the rooms. At the final stage, water is directed to the taps to provide hot water for the house.
