On-demand, tankless, or instantaneous water heaters heat water instantly when it is called for, and so there is no demand for a storage 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 turns with a heat exchanger that is surrounded by flame, and hot water exits the opposite of the heat exchanger.

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