Replacement tankless water heaters start to operate to give you hot water as soon as you’ve turned on the hot water tap. Water will enter the heater & it will be detected by a water flow detector. Then the computer component of the unit will automatically ignite the burner which will permeate the water through the heat exchange.

The heat exchanger will then heat the water to your desired temperature. Lastly, the unit will shut down as soon as you’ve turned off the tap. Here are some replacement tankless water heaters to contemplate.
