ETS storage heaters are designed to bring you top performance on an extremely small footprint. The high-grade thermosolid insulating technology provides a considerable heat retention capability. It ensures that the heater gives off its heat when it is needed. A highly efficient storage core keeps the capacity required for heating on standby. The connected room temperature controller comes into play when the actual room temperature falls below the required level. The fan then blows a pleasant level of warmth into the entire room - almost silently. The device can be charged manually or centrally via the charge controller. The ETS casing is made from painted sheet steel. Its compact dimensions save space and make this storage heater extremely easy to install and service.
