NOTES
This diagram shows the processes involved in a house’s central heating system.
Firstly, cold water comes into the house filling the water storage tank. Excess water is stored in the water tank above. The water is transported into different pipes. Some of it is transferred to the taps, while some of it is transferred to the boiler, which heats the water before moving it to the pump. The pump increases the water pressure and pushes the hot water to the radiators. Here the small tubes feed the water into radiator.
The diagram shows how products are being manufactured from raw materials and other components. The diagram also shows how these products are assessed back in the factory and finally how feedback is given.
