On-demand, tankless, or instant water heaters heat water instantly when it is asked for, and so there is no need 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, igniting 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 other 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 efficient. One possible problem is pressure drop throughout the heat exchanger which can produce lower flows when more then one source of hot water is utilized.
