NIBE S2125-8 & S2125-12 Air/Water Heat Pump (3x400V)

Description

Set a new benchmark in home heating efficiency with the NIBE S2125 (400V 3-phase)—an intelligent, top-tier inverter-controlled air/water heat pump. The NIBE S2125 automatically adjusts its output to match your home’s exact heat demand year-round, delivering maximum energy savings and minimal operating costs. It combines class-leading thermal performance with an ultra-quiet outdoor unit design.

PLEASE NOTE: Velltra guarantees that all NIBE products marketed and sold by us are manufactured in Sweden and built with top-tier components specifically engineered for Nordic markets and harsh winter climates.

Outstanding Performance in Cold Climates The NIBE S2125 offers an optimized seasonal efficiency factor, achieving a remarkable SCOP of 5.0 (at average climate 35/55 °C per EN 14825:2018) and a SCOP > 4.1 in cold climate conditions. The system boasts an extended operating range capable of delivering supply water temperatures up to 75 °C. Even during severe sub-zero winters down to –25 °C, it continues to supply flow temperatures up to 65 °C—making it ideal for both new construction and retrofitting existing radiator systems.

Smart Connected Home Integration When connected to a NIBE S-series indoor module, the heat pump provides native Wi-Fi connectivity and support for wireless smart home accessories. The system automatically adjusts indoor comfort based on weather forecasts and usage patterns. Full control over energy usage is accessible anywhere via the myUplink app on your smartphone or tablet.
