On-demand, tankless, or instantaneous water heaters heat water instantly when it is asked for, therefore there is no need for a storage tank. On-demand water heaters are triggered 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 turns with a heat exchanger that is surrounded by flame, and hot water exits the various other 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 effective. One prospective problem is pressure drop throughout the heat exchanger which might produce lower flows when more then one source of hot water is made use of.
