The new air/water heat pump is powerful, compact and quiet
NIBE S2125-8/12 is the most powerful air/water heat pump from NIBE to date. With high supply temperature,
low noise level and all the smart functions that the new connected platform means give it comfort and energy efficiency all year round.
In combination with an indoor module from the S series, it provides all the advantages that the new digital technology platform provides.
The best air/water heat pump we have ever made
NIBE S2125 is the result of our persistence that always makes our products the best they can be. So that we constantly have to think in new ways, use our knowledge of the harsh climate and test our ideas. Until we have developed the best solutions that keep what we promise.
- Product information
- Advantages
NIBE S2125 is an intelligent inverter controlled air / water heat pump. With NIBE indoor modules, it forms a highly efficient climate system for your home. The heat pump operates with a natural refrigerant for a sustainable impact on the climate and the environment. It provides optimized savings because it automatically adapts to the home's power needs.
NIBE S2125 has an optimised annual heating factor, which provides a low operating cost and hot water with high performance. The working area provides a single-flow temperature of up to 75 °C. At an outdoor temperature of down to -25 °C, up to 65 °C is still delivered, while the sound level is low.
Together with the NIBE S-series indoor module with built-in wifi connection and the possibility of wireless accessories, it becomes a natural part of your connected home. The smart technology automatically adjusts the indoor climate and gives you complete control of the system from your smartphone or tablet. High comfort and low energy consumption - at the same time as you do nature a favour.
LOW OPERATING COSTS
Optimized seasonal performance factor, low operating costs and high-performance hot water, using a natural refrigerant for a low environmental impact.
CLASS-LEADING WORK AREA
Operating range up to 75°C supply temperature and 65°C at –25 °C outdoor temperature.
LOW NOISE LEVEL
New design for low noise level.

NIBE KVR 11-60
The NIBE KVR range provides installers with a simple, reliable and freeze protected way to manage condensate drainage from NIBE air source heat pumps. KVR 11 is for the S2125 range and is available in multiple lengths, indicated by the suffix; for example, KVR 11-10 = 1 m, KVR 11-30 = 3 m, and KVR 11-60 = 6 m. All variants combine insulated pipework with a thermostat-controlled heating cable that automatically prevents ice formation, ensuring safe drainage even in sub-zero conditions and protecting the heat pump from backflow, frost damage or condensate pooling.

NIBE ELK 213 EXP
The NIBE ELK 213 acts as source of supplementary heat for NIBE heat pump systems, for up to 13kW output. It integrates seamlessly with NIBE systems, allowing the heat pump to activate electric backup automatically during peak loads, cold weather or rapid reheat periods. Multi-stage output control ensures smooth modulation and avoids unnecessary electrical demand. It also incorporates built-in safety features, including thermostats, temperature limiters and circuit protection, making the range suitable for compliant, predictable and installer-friendly system design.
NIBE CPD 11-25/75
The CPD 11-25/75 is a high-efficiency circulation pump, rated to 7.5 bar, designed to ensure stable and reliable flow within NIBE heating and cooling systems. Supplied as a compact, pre-assembled pump unit, it provides consistent circulation for underfloor heating, radiator circuits, buffer charging and other secondary loops where dependable flow is essential for correct heat-pump operation.
