The Dimplex DuoHeat Radiator provides an automatic mix of off-peak storage heating and direct-acting convection heating in one package, allowing flexibility and controllability to match users lifestyles while keeping running costs low. It offers energy-efficiency savings of up to 10% compared with traditional off-peak electric heating systems, recognised by SAP2005, the tool for showing compliance with Part L of the Building Regulations. The radiator will automatically determine how much heat needs to be stored each night depending on changing weather conditions. The stored heat is then gradually released over the course of the following day.
