How Heating is done

In a tankless water heater, the heating is done only when there is a need. As soon as the hot water faucet is opened, it means that the elements of the heater in-charge to heat the water is turned on also. As water passes to this part, it is heated.

It stops heating water when the fixture is also turned off. It saves energy since water in this tankless heater is stored cold compared to tanks where water is warm.
