The Essential Guide to Storage Heaters

Storage heaters are the perfect solution for households on a time of day tariff such as the Economy 7 electricity system. When used in conjunction with these types of electricity tariffs, storage heaters can provide money saving benefits. This is because they take advantage of cheaper overnight electricity rates.

Storage heaters are electric heaters that store thermal energy through the heating of internal ceramic bricks during the night. The stored heat can then warm the property during the day. These systems are particularly ideal for homes that don't have access to a gas central heating system such as rural properties.

What storage heaters are available?

Manual storage heater

Manual storage heaters are the most basic and affordable style available. Storing heat over night and releasing warmth automatically during the day. These are not the most cost effective range because they continue to heat until manually switched off.

Automatic storage heater

This style of storage heater features an inbuilt thermostat that controls the amount of thermal energy stored according to the room temperature. Other automatic storage heaters feature a combination system which also incorporates a traditional electric convection heater. The convector fan offers on demand heating, ideal when an extra heat boost is needed.

Quantum Storage

This modernised range is fan-assisted to use less electricity meaning they tend to be cheaper to power than other models. Quantum storage heaters also often feature a high quality LCD control panel for accurate room temperature selection. This also allows you to tailor the heating programmes to suit your property. These are however the most expensive upfront but they offer greater efficiency.


  • Utilises cheaper off-peak electricity to heat the home during the day on Economy 7 or Economy 10 electricity tariffs
  • Modern models are now more efficient as they allow more control over your heating; this includes the automatic and quantum ranges
  • Many modern types include a built-in thermostat, releasing heat only when needed
  • Simple installation
  • Quiet when in use, even with a fan convector
  • Compatible with renewable energy sources such as solar, wind and hydroelectric


  • Weather dependent, meaning you can accidentally over heat or under heat your home during periods of unpredictable temperatures
  • Only cost effective when not connected to the gas grid as electricity is overall more expensive
  • Basic manual models can result in inefficient heating
  • Unavoidable heating will occur overnight when charging
  • By the evening much of the stored heat has usually been released
