The given diagram illustrates the working mechanism of a central heating system of a house.

Overall, the process of heating water for the house occurs in 3 major steps, which includes, collection and storage of cold water, heating and distribution/transfer of it to taps and radiators.

To begin with, a pipe on the roof of the house helps to supply cold water to the water channels inside the home. Additionally, a water tank is also placed nearby the pipeline, which later fills the water storage tank of the building. Thereafter, the excess water from this tank flows directly from an overflow pipe and passes down in two ways leading to the storage tank at one end and a hot water tap on the other.

After that a boiler is used to heat-up the water by the help of either gas or oil. On the other side of the boiler, a cylindrical pump is present which transfers the hot water to the hot water radiators and taps via pipes.
