NIBE S1156 is an intelligent inverter-controlled ground source heat pump with a new, more climate-friendly refrigerant. The product does not have an integrated hot water tank, which makes it easy to place at lower ceiling heights. The separate hot water tank is selected based on hot water needs. S1156 helps you not to use more energy than you need because the heat pump automatically adapts to your heating needs. With extensive experience in ground source heat pumps and innovative technology, it is our most energy-efficient ground source heat pump.
