The different 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. Sensible heat 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.

Electric thermal storage, or ETS, is an electric home heating device containing ceramic bricks that can help lower your heating costs by storing heat when electricity costs less and then releasing the heat throughout the day. Our time-of-day (TOD) rates are what makes an ETS cost-efficient. TOD rates change depending on the overall power demand
