The picture below demonstrates the process of the central heating system in a residence.

Overall, we can see various steps involved in heating the water to keep the temperature warm in the house. Steps like storing the water in storage containers, introducing boilers to heat up the water and at last using radiators to heat up the room.

Firstly, there is a water container in the top that is used to fill up the storage containers. A stream of cold water flows through pipes and reaches the storage containers. Boilers are activated by gas or oil to heat the water to a certain temperature and then pumped back through pipes for daily use like hot water taps.

Later on, the hot water is sent along with pipes to multiple hot water radiators having small tubes in the residence, along with an active flow of cold water below.

Consequently the radiators help the room to be warm. This is a continuous process.
