On-demand, tankless, or rapid water heaters heat water immediately when it is required, and so there is no demand 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, sparking the burner. Cold water gets in one side of a coil of copper pipe, which then turns through 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 on the heat transfer effectiveness of the heat exchanger and is 75 to 90 percent efficient. One prospective problem is pressure drop across the heat exchanger which could produce lower flows when more then one source of hot water is utilized.
