NIBE S1157 PC is an intelligent, inverter-controlled ground source heat pump for both new builds and replacement of existing heating systems. Its compact design makes it possible to install the unit in spaces with low ceiling height, while a separate water heater allows the hot water capacity to be adapted to your needs. With a seasonal coefficient of performance (SCOP) of up to 5.9, the S1157 PC helps keep running costs low while adapting to the building’s heating demand. It also features built-in passive cooling, which lowers the temperature without the compressor having to run. This keeps your home cool on warm summer days in a quiet, energy-efficient and natural way.
The S1157 PC uses the natural refrigerant R290, which has a low GWP, is PFAS-free and does not require annual inspections. This makes it a sustainable solution for the future.
Thanks to NIBE Sense, the S1157 PC connects to your smart home and optimises energy use according to heating demand, electricity prices and outdoor conditions, without compromising on comfort. Automatic software updates allow it to keep developing, meet future requirements and remain a sustainable long-term heating solution.

This wireless sensor allows you to read the CO2, temperature and humidity level in a room or climate zone using the myUplink app. For NIBE S-series heating installations with ventilation the indoor comfort level can automatically be adjusted to give you a comfortable indoor climate. For example, you can increase ventilation and lower the CO2 level when there are a lot of people present or lower the ventilation to further reduce your energy costs. Because it is battery powered, it is easy to install, but it can also operate with an external power source using a micro USB.
Mount the sensor in your room and connect it to your NIBE S-Series heat and ventilation installation.
ECS 40 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
The NIBE ECS 41 kit allows installers to add one or more additional heating circuits to a NIBE heat pump installation where different supply temperatures are required, such as radiator and underfloor heating combinations. Each kit includes a dedicated AXC accessory module, shunt valve, shunt motor, circulation pump and temperature sensor, enabling the new zone to run as a fully controlled climate system with independent flow temperature, heating curve and pump operation. The ECS 41 is sized for larger UFH areas above 80 m².
