How to use storage heaters

Storage heater

Storage heaters are designed to build up energy during off-peak periods, usually overnight.

It's important to get the settings right to make sure you're saving as much energy and money as possible.

Most storage heaters have a separate 'on'/'off' switch on the wall next to them. The switch should be left in the 'on' position throughout the times of year that you regularly need heating.

Most storage heaters have two controls. They are usually on the top right-hand side of the heater, sometimes under a flap:

  • 'Input' (or 'charge control') - This controls how much heat you store. The higher the input, the more heat you'll store and the more electricity you'll use. You should only need to adjust the input control setting when the outside temperature changes.
  • 'Output' (or 'boost') - This controls how much of the stored heat is released. The higher the value, the more heat is released. You'll only be increasing how much heat you let out though, you won't be using any more electricity.

To run a heater economically during the day set the output at the lowest setting when you leave the house, and put it back up when you return. This will reduce unnecessary heat loss. It is recommended that overnight the output is set to minimum to prevent heat loss through the night. This will prevent the storage heaters using more electricity overnight as they try to refill the bricks with heat. It will also save enough stored heat to call on during the day.

You can control storage heaters individually. This means you can choose different heat settings for different rooms.

  • Input

    • This controls how much energy you store.

      The higher the input, the more heat you’ll store and the more electricity you’ll use.

      You should only need to adjust the input control setting when the temperature changes outdoors.

      •    In the warmer months you should experiment with the input so it meets your needs during the day and you avoid over-charging the bricks. If you don’t need any heating turn it off at the switch.
      •    In winter, or any other time when it’s too cold for comfort, the input should be set to its maximum in your main living space so that the heater has enough stored heat to last all day.  
      •    You could also experiment in each room as above, depending on how much that room is used.
  • Output

    • This controls how much of the stored heat is released.

      You’ll only be increasing how much heat you let out though, you won’t be using any more electricity.

      During the day set the output at the lowest setting when you leave the house, and put it back up when you return.

      This will reduce unnecessary loss of heat.

      Overnight the output should be set to minimum to prevent heat loss through the night.

      This will prevent the storage heaters using more electricity overnight as they try to refill the bricks with heat.

      It will also save enough stored heat to call on during the day.

      •    Never cover the surfaces or obstruct the air vents;
      •    fitting a guard if you have young children or pets;
      •    Make sure there’s a gap of at least 6” (150mm) between your curtains and the top of the heater.
