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 activated by the flow of water. When there is need for hot water, a fuel valve opens, sparking the burner. Cold water enters 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 other individual side 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 can produce lower flows when more then one source of hot water is made use of.
