Danfoss radiator thermostats are helping people to obtain comfort in their homes and maintain constant desired room temperatures, individually room by room, and 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.

FAQ

How to save energy with using all radiators?

You save nothing by having one on full throttle and the others closed. In fact, a fully heated radiator will use more heat than 2 or 3 that are turned only a quarter of the up. This is especially true when you use district heating.

How to ventilate a room?

When ventilating a room, turn down your thermostat and leave the windows open for 5-6 minutes. If you don’t turn down your thermostat, it will react to the draft by heating up automatically.

What should be minimum temperature in a room?

Always maintain a minimum of 16 degrees in all rooms. Never go below 14 degrees; this might damage the building and cause dampness, condensation and mold.

How to use sleep mode?

Save energy and money by turning your radiators down 2-3 degrees at night. But remember: If you turn them down more than 3 degrees, the money you could save will be used on reheating the room again.
