Sample Answer:
The given diagram shows the working process of a central heating system of a house. As is seen in the given picture, central heating system runs various processes to keep working.

The central heating system requires a combination of tools and process flow including water tank to storage tanks, boiler and pump. The water tank is placed at the roof of the house and this is used to supply water to the storage tank. The water from the tank flows to the storage tank and excess water in the water tank passes through the overflow pipe. The overflow pipe is linked to the hot water tap. Storage tank supplies water to a boiler which is powered by either oil or gas. The boiler increases the temperature of the water and the joint hot water radiators get heat to keep the entire house warm. The radiators are placed around the house to maintain the hot temperature of the house. The radiators have several small tubes and get the temperature to keep the house warm from the flowing hot water. The pump machine keeps the water flowing and it is placed at the bottom left corner of the boiler.

The whole process makes sure that the desired temperature of the house is maintained and hot and cold water supply of water is remains functional.
