1.7 MECHANISMS OF HEAT TRANSFER

Heat storage unit

The kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall. An electric thermal storage heater is a stand-alone, off-peak heating system that eliminates the need for a backup fossil fuel heating system that is wall-mounted and looks a bit like a radiator that contains a ‘bank’ of specially designed, high-density ceramic bricks.
