High efficiency, intelligent and powerful inverter controlled ground source heat pump available in three output sizes.
Indoor heat pump unit. Suitable for a large range of residential properties including older properties with higher heat loss.
NIBE S1156 is an intelligent and powerful inverter controlled ground source heat pump in three output sizes. It provides optimum savings as the heat pump performs efficiently and automatically adapts to the property’s output requirements all year round.
It has a high seasonal coefficient of performance and an operating range of 1.5-18kW. With just over 1 ton CO2 equivalent refrigerant volume (in the largest unit). The modulating compressor provides efficient output regulation and high reliability, making the heat pump suitable for most properties even with larger heating requirements.
Thanks to smart technology and an intuitive touch screen, the heat pump gives the user full control over energy consumption and the Intelligent controller automatically adjusts the indoor climate for maximum comfort & efficiency.
The S1156-8 PC variant of this product comes with all passive cooling accessories pre-built into the heat pump unit.
