What are applications of Electrical geysers?

Answer 1

An electrical geyser is a sizable container which heats water using an electrical element,

much like the element in a kettle.

Unlike a kettle a geyser has a thermal switch that switches the element on and off.

This is to control the temperature and control power consumption.

A geyser is fitted with valves than control pressure caused by the expansion and possible over heating of the geyser. Over heating or faulty valves can cause a geyser to rupture causing damage or possibly injury (although the later is very unlikely).

This is the extent of my knowledge on the subject so if you feel the need to correct or add anything please feel free.

Answer 2

Geysers, underground sources of heated water, are used to drive turbines to generate electricity in places where geysers are common, for example in Iceland.

Answer 3

However, if some places, ""geyser" is a Plumbing term for a water heater, There an electrical geyser would mean an electric water heater, used to provide hot water for bathing, laundry, etc.
