instant heater

Immediate heat source

An instant heater is a device that heats water on demand rather than storing it in a tank.

Also called a tankless or on-demand heater, it activates when you turn on the tap and stops when you turn it off: The instant heater means we never run out of hot water.

The term sometimes applies to portable space heaters that produce warmth immediately.
