Hybrid heating: wood log boiler Smart-HV and heat pump

At this installation, an existing heat pump was supplemented with a Hargassner Smart-HV 17 wood log boiler featuring return temperature protection. The combination creates a flexible heating system. The intelligent integration of the heat pump and wood gasification boiler provides comfort in heat generation.

The Smart-HV is equipped with a return temperature protection unit (RLA). In this process, warm supply water is fed into the return line, reducing the temperature difference. This protects the boiler and enables low-maintenance operation. The RAG unit automatically manages the boiler’s return temperature protection while simultaneously charging the accumulator tank.
