How do hybrid heat pumps work? They provide the perfect blend of two energies. Combining the strengths of an Air/Water heat pump with those of a boiler, hybrid heat pumps adapt in real time to changes in climate and thermal demand. What does this achieve? Unrivalled thermal comfort and yearround, best-in-class energy performance. *Available for Alfea Hybrid Duo Fuel oil and Alfea Hybrid Duo Gas Hybrid heat pump The hybrid heat pump automatically sets the most efficient operating mode: • Focus on heat pumps to generate energy savings. • The boiler is activated during peak demand for heating and Domestic Hot Water (DHW), as well as extreme temperatures and whenever it is more cost-effective. Air/Water heat pump This heating system collects heat from the outside before resupplying it inside the home using heat-conducting fluid. Provided it is cost-effective, the system will continue to run. Boiler In response to falling temperatures, the gas or fuel oil boiler is activated, thereby maximising heating comfort. The heat pump alone reaches flow temperature. The heat pump alone does not reach flow temperature: both generators operate simultaneously. Outdoor temperature outside the heat pump operating zone: the boiler operates independently. “Heat pump focus” control How exactly do these technologies combine? Focus on DHW in operation Alfea Hybrid Fuel oil A.I. and Gas Two operating modes: To maximise savings, consider changing the DHW control system. The boiler operates as soon as DHW is required to ensure comfort within the home. INSTANT MODE (STANDARD): for DHW, before heating the primary network at its maximum capacity. The boiler then kick-starts operations, providing a muchneeded boost to energy. REPLACEMENT MODE: 1 2 The heat pump operates first, in response to demand 87
