Overview
- The SOKTNEU radiator fan is listed on Amazon for €40.99 with a €5 coupon, with a two‑pack at €74.99, a 4.5/5 rating from 97 reviews, and over 400 units sold last month.
- The SOKTNEU model draws about 1.2 watts and uses a temperature sensor to switch on near 30°C and off around 25°C, with coverage emphasizing quiet operation.
- Newer radiator fan designs add user‑set start thresholds and optional manual activation, addressing earlier noise complaints and improving compatibility with different heating systems.
- Outlets say fans can speed room warming and enable about 5–10% savings when users lower flow temperatures or thermostat setpoints, with simple, tool‑free mounting under or behind radiators.
- Tenants are advised to verify billing methods because fans can distort readings from heat‑cost allocators, and reviewers stress these devices complement rather than replace smart thermostats.
