The illustration displays the operation of the domestic heating system.
As observed, the central heating machine comprises of several mechanical aspects and forms a complex system that includes a storage tank, conducting pipes, a boiler and radiators.
To begin with, the cold water that enters the house is stored in a large overhead tank. From here, the water flows down to the boiler through the overflow pipes. The boiler heats up the water that passes through it, which is usually fuelled by gas or oil. The hot water then circulates around the house through a system of pipes and flows into the radiators located in the moms. The small tubes inside the radiators help distribute the heat. This warms the house.
The cold water then after, is pumped back to the boiler to be reheated and circulated around the house again. It is also observed that some of the water from the boiler is stored in the storage tank from where some of it is directed to the taps to provide hot water for other purposes.
Overall, it can be seen that the domestic central heating system functions efficiently through a systematic mechanized process.
