Editing Storage heater (section)

==Principle of operation==
Storage heaters are typically composed of [[clay]] [[brick]]s or other [[ceramic]] material ([[grog (clay)|grog]]), of concrete walls, or of water containers. There are also special materials such as [[feolite]]. This material serves as a heat storage medium. There are electrical [[heating element]]s embedded in the material which can be switched on to heat the storage medium and thus to store energy.

The stored heat is given off continuously (through [[thermal radiation]] and [[convection]]). To speed up the [[heat transfer]], storage heaters may come equipped with [[mechanical fan]]s that can move air through the heater; see the [[#Fan-assisted storage heaters|section on fan-assisted storage heaters]].
