The diagram illustrate how a central heating system functions and keep the house warm.
Overall, it can be seen that the central heating system works through a sophisticated procedure where it requires 3 steps for the hot water to reach the taps and more stages are needed for the radiators to be heated. Moreover, several instruments such as a storage tank, boiler, pump and hot water radiator are required for this complex process.
The process begins when cold water is supplied from the outside source and it is flowed down to the storage tank. After reaching the storage tank, excess cold water is moved via an overflow pipe to the water tank for reservation. In the next stage, water is transferred to the boiler, which runs by gas or oil and it is responsible for heating the water. When this stage is completed, the hot water can either go to the taps for use in the households or to the hot water radiators for warming the house.
Hot water radiators are made up of small tubes which radiates the heat of the hot water in order to keep the house warm. When the temperature of the water is completely dissipated and it becomes cold, then this water can be pumped back to the boiler by a pump attached with it for reuse
