On-demand, tankless, or instantaneous water heaters heat water instantaneously when it is asked for, therefore there is no need for a tank. On-demand water heaters are triggered by the flow of water. When there is need for hot water, a fuel valve opens, igniting the burner. Cold water enters one side of a coil of copper pipe, which then turns with a heat exchanger that is surrounded by flame, and hot water exits the other side of the heat exchanger.

The efficiency of an on-demand water heater is based on the heat transfer efficiency of the heat exchanger and is 75 to 90 percent effective. One prospective issue is pressure drop across the heat exchanger which could produce lower flows when more then one source of hot water is utilized.
