- 1High heat retention storage heatersIndicative cost: £1,200 - £1,800
Modern storage heaters are less expensive to run than the direct acting, on-peak heating system in the property. A dual-rate electricity supply is required to provide the off-peak electricity that these heaters use; this is easily obtained by contacting the energy supplier. Ask for a quotation for high heat retention heaters with automatic charge and output controls. As installations should be in accordance with the national wiring standards, only a qualified electrician should carry out the installation. It is best to obtain advice from a qualified electrical heating engineer. Ask a qualified electrical heating engineer to explain the options, which might also include switching to other forms of electric heating.
