Also known as demand or instantaneous water heaters, these systems do not have a storage tank. They heat water only when it is needed, which avoids standby heat loss through tank walls and water pipes. The most basic units consist of either an electric element or a gas burner surrounded by flowing water.

Tankless water heaters are usually installed near the "point-of-use" to serve a specific need, such as under a kitchen sink. Depending on overall water usage, they may not have the capacity to supply an entire home with hot water. For this reason, they are often used as booster heaters to supplement another water heating system.

A relatively new tankless technology - the low mass water heater - is capable of supplying much more hot water to the home. These systems are typically gas-fired with electronic ignition and power exhaust, which means they are also more efficient than conventional tankless heaters. They can be connected to an external storage tank, if necessary.
