Danfoss radiator thermostats help people to obtain comfort in their homes. By maintaining constant desired room temperatures, individually or room by room, and by helping to reduce energy consumption.
They can save approximately 20% compared to a manually operated valve due to utilization of free heat gains and constant room temperature.
Robustly built and designed to meet the rigors of domestic life, we offer an extensive range of radiator thermostats that increase comfort and save energy.
Features and benefits
Ensures optimal confort at home, room by room.
The world’s only radiator thermostat with gas-filled sensor: One of the secrets of the radiator thermostat’s service life of over 20 years is the gas charged, precision-manufactured sensors. Unlike other fillings, gas maintains a high regulating capacity and reactivity.
