On-demand, tankless, or rapid water heaters heat water instantaneously when it is called for, therefore there is no requirement for a storage 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 gets in one side of a coil of copper pipe, which then twists through 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 efficiency of the heat exchanger and is 75 to 90 percent reliable. One potential problem is pressure drop across the heat exchanger which might produce lower flows when more then one source of hot water is utilized.
