The diagram below shows how the central heating system in the house works
The diagram illustrates an overview of domestic house heating system.
As can be seen from the chart, there are 3 main stages to ensure water to the radiators and taps through pipes ,a boiler and a tank.
The process begins with the cold water from both the outside and the water tank in the top roof being stored by the storage tank .From there, the water flows down to the boiler ,located on the ground floor. Besides, the boiler, which is fuelled by gas and oil,heats the water as it passes through. Through the pipes , the water is then pumped around the house and circulated through the radiators ,which have small tubes inside them to help contribute the heat and warm up each room . Meanwhile, some water is directed to the taps to provide hot water for the house.
As the water has been through the pipes and radiators, it is returned to the boiler to be reheated and circulated around the house again.
