Storage heaters are usually used in conjunction with a [[Electricity meter#Multiple tariff|two-tariff electricity meter]] which records separately the electricity used during the off-peak period so that it can be billed at a lower rate. In order to enjoy the lower rates, the house must be on a special electricity tariff. In most countries, storage heaters are only economical (compared to other forms of heating) when used with such a special tariff. In the [[United Kingdom]] the [[Economy 7]] tariff is appropriate.

Storage heaters usually have two controls: a charge control (often called "input"), which controls the amount of heat stored, and the draught control (often called "output"), which controls the rate at which heat is released. These controls may be controlled by the user, or may operate automatically once the user selects the target room temperature on a [[thermostat]].

Storage heaters may also incorporate an electric heater (utilizing either resistance heaters or [[heat pump]]s), which can be used to increase heat output. Such added heating, if it is resistance heating, is expensive, as it occurs during the high-tariff time of day.
