How Does a Tankless Water Heater Work?

Tankless heater system heats water directly without using a storage tank. What happens is that when a hot water tap is turned on, cold water flows through a pipe into the heater. An electric element or gas burner will then heat the water. As a result, tankless systems deliver constant supply of hot water.

The heater will adjust the flame output to ensure that the temperature set point is constantly maintained. When you shut off the hot water fixture, cold water stops flowing into the heater and the flame extinguishes. A standard tankless water heater can provide hot water at a rate of 2- 5 gallons per minute.
