What Are Storage Heaters?
Storage heaters are a form of electric heating system traditionally used in off-gas areas, they first became popular in the 1950s and there are still hundreds of thousands of homes using them today unaware that they are a problem. They are big and clunky in design, filled with clay bricks which are designed to absorb heating when turned on and distribute it to the home over a longer period of time.
How Do They Work?
Storage heaters work using a special electricity tariff called economy7 which is a two-rate tariff, the electricity is charged at a more expensive rate during the day than it is the night. People with storage heaters turn them on during the night to charge the clay bricks and then turn them off in the morning when the electricity becomes more expensive again. The plan behind this is the storage heaters then heat the house during the day.
Is Economy 7 Being Phased Out?
Unless you already have a two-rate meter you may find it difficult to find a supplier that would install one for you, or offer you an economy7 tariff. Many suppliers now use economy10 tariffs using a special meter which provides 3 low-cost time zones throughout the day. This is great and offers slightly more flexibility however outwith these times electricity can be very expensive so you need to be very mindful about how you use them.
