The SBP 700 E SOL is a cylinder with 700 l nominal capacity for the hydraulic separation of the volume flow of the heat pump and the heating circuit, plus the optional connection of a solid fuel boiler and the integration of solar heating systems into the conventional heating system. The solar heat will be transferred to the heating water through an internal 2 m² smooth-tube heat exchanger. The installation of two threaded BGC electric immersion heaters is possible. The 80 mm thermal insulation, as directly applied PU foam insulation, ensures especially low heat losses and is protected with a high-grade external plastic jacket.
