Storage heaters are a cleverly designed heater that work by storing thermal energy at night to be released slowly the following day. Because electricity is cheaper at night than during the day, a storage heater can allow big savings to be made. These types of heater are generally made from high density bricks that work as excellent insulators. Additional insulator panels are used between the bricks and outside them too in order for the heat to be slowly released into the home or building without much waste. Night storage heaters are an economical way to heat a home or office.
Normally storage heaters have two controls – an input control and an output control. The input control is called a charge control and it controls the amount of heat that is being stored by the heater. The output control is more correctly known as the draught control, and this controls the rate at which heat is released from the heater into the property.
