The Briz Storm Right 100 water heater is a classic indirect heating boiler. In addition to the standard electric heating element, a tube is installed in the boiler - a heat exchanger, to which any alternative heating source can be connected. This could be your hot water heating system, solar collector, heat pump, or other hot water heating technology. Due to this, during the operation of the alternative heating source, the Briz Strong boiler will not waste electricity, and the electric wet heating element will be connected only when necessary.
