  Water heater - Wikipedia, the free encyclopedia
Tank-type water heaters can be made more efficient by installation of additional insulation jackets around the tank, flow valve devices at their inlet and outlet, cycle timers, electronic ignition (in the case of fuel-using models), sealed air intake systems (in the case of fuel-using models), and pipe insulation.
In British English, water heaters are known as boilers,or "Geysers"(pronounced Geezers), feeding a separate hot water tank.
These water heaters heat the water as the water flows through the device, and do not retain any water internally except for what is in the pipe.
