On-demand, tankless, or instant water heaters heat water instantly when it is required, therefore there is no demand 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, firing up the burner. Cold water gets in one side of a coil of copper pipe, which then twists with a heat exchanger that is surrounded by flame, and hot water exits the other individual side 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 throughout the heat exchanger which can produce lower flows when more then one source of hot water is utilized.
