On-demand, tankless, or instantaneous water heaters heat water immediately when it is called for, therefore there is no need for a tank. On-demand water heaters are activated by the flow of water. When there is demand for hot water, a fuel valve opens, firing up 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 opposite of the heat exchanger.

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