NIBE S2125 is an intelligent, inverter-controlled air/water pump. With NIBE indoor modules, it forms a very efficient climate system and provides optimised savings as it automatically adapts to a homes output requirements all year around.

The NIBE S2125 has an optimised seasonal performance factor, which results in low operating costs and high-performance hot water. The working area gives a supply temperature of up to 75°C. At an outdoor temperature down towards –25°C, it still delivers up to 65°C, while the noise level stays low.

Features and benefits:

Optimised seasonal performance factor and low operating costs.
Low GWP R290 refrigerant.
Working range up to 75°C supply temperature and 65°C at an outdoor temperature of –25°C.
New design for low noise level.
High comfort and low energy levels.
Available in two power sizes, S2125-8 and S2125-12.
Intended to be combined with the NIBE S-series indoor module.
A wide range of system solutions and accessories.
EN 14825 SCOP of 5.00 for an average climate at 35°C flow temperature.

The NIBE S2125 requires pairing with a NIBE controller or hydraulic module, from the following:

SMO S40 - NIBE S-series controller and wiring centre, supporting:

Control of up to 8 x S2125 products in a single system.
Control of up to 8 flow temperature controlled heating/cooling zones with the NIBE Extra Climate System accessory.
Control of up to 8 x NIBE ERS Mechanical Ventilation Heat Recovery (MVHR) units.
Control of active cooling through either a 2-pipe or 4-pipe distribution system.
Control of bi-valiant heating systems utilising a secondary heat source as a back-up.
Wi-Fi enabled to allow for connectivity to the myUplink and myUplink PRO remote monitoring, control and diagnostics platforms for homeowners and installers.
Wireless connectivity to the range of myUplink smart home accessories for demand controlled ventilation, cooling and heating. Sensors include smart radiator valves in addition to wireless humidity, CO2 and temperature sensors.
