On-demand, tankless, or rapid water heaters heat water immediately when it is called for, and so there is no requirement 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, stiring up the burner. Cold water enters 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 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 effective. One potential issue is pressure drop across the heat exchanger which could produce lower flows when more then one source of hot water is utilized.
