More comfort and lower energy consumption thanks to Danfoss's smart electronic thermostats

Energy consumption is reduced by


- and on top of that the whole family is spared from temperature fluctuations!

"The opportunity to set the temperature in every room from a central point gives homeowners a high level of control over their room temperatures – at any time of day or night. We no longer need to worry about turning the thermostats up or down: we can get a pleasant level of warmth in every room at the touch of a button."

Vivi, X-ray assistant, Solbjerg

Optimal room temperature 

After having built their new house in Solbjerg, Vivi and Klaus had problems with temperature regulation for 10 years. When considering their options, they chose Danfoss Link™ – and have no regrets. The room temperature is now improved considerably and when they come home, the rooms have already been preheated to a pleasant temperature.

Even room temperatures

By installing Danfoss Link™ Connect Thermostats we were able to resolve difficulties in maintaining a constant temperature. From a practical perspective, radiators and the underfloor heating can be regulated by a single system – and large temperature fluctuations are a thing of the past.

The initial situation of the family from Solbjerg

The 163 m2 brick house was built in 2000 and equipped with central heating. The house is equipped with radiators and underfloor heating. In February 2012 the family decides to install a comprehensive Danfoss Link™ solution.


The Danfoss Link™ solution

  • bullit.png Eight electronic Danfoss Link™ Connect Thermostats were installed on all radiators in the house. The Connect Thermostat automatically switches off each radiator for around 30 minutes as soon as a temperature decrease from open windows is registered.
  • bullit.png A Central Controller with a control panel automatically controls all radiator thermostats so the temperature in each room can be set individually. Danfoss Link™ offers a range of functions: for example, using the absence function the thermostat can be set to reduce the temperature at night or when nobody is in the house.
  • bullit.png Four RS Room Sensors measure the temperature of each room and ensure that a selected temperature is maintained as desired.
  • bullit.png Three small TWA actuators form part of the underfloor heating system. 

  • bullit.png A Danfoss Link™ HC Hydronic Controller regulates the underfloor heating.

Energy savings is a special bonus 

Since the installation of Danfoss Link™, the family in Solbjerg has enjoyed the reassuring certainty that no energy is wasted in their absence. The new thermostats also make a positive impact on the heating bills. Since installing Danfoss Link™, the family's heating costs have been even 28% lower than previously estimated.
