How it works
6 good reasons to take a closer look at Danfoss Icon2™ floor heating

All underfloor heating products can be changed to Danfoss Icon2™ with all the new functions that modern underfloor heating control can offer. Only electronic components need to be replaced and the installer can do it in just a few hours. There are no floors to break up and no water to be drained from the system.

We have solutions for every need and even for floor heating enthusiasts, see the benefits for each solution and where you get the “little extra”. Learn more about the different variants in Danfoss Icon2™ here.

We recommend that an underfloor heating system be installed and regulated by a professional installer. We have gathered all the information an installer needs to be able to advise you.

According to the Danish Technological Institute, you save approx. 5% energy for each degree you turn down. Danfoss Icon2™ automatically regulates so that only the absolutely necessary energy is used to achieve the desired comfort. Therefore, with Danfoss Icon2™ you can lower the temperature a little without losing comfort and thus save energy.

Do you have rooms that do not get enough heat? Or is the heat distributed unevenly?
Danfoss Icon2™ has automatic balancing. This means that all rooms get exactly the heat they are set for. And pre-setting is not necessary.

The elegant room thermostats in the Danfoss Icon2™ series are inspired by simple design. The display turns off automatically when not in use, and the design is just as discreet as a light switch. Choose infrared sensor for bathrooms, so you are always guaranteed a nice warm floor.

Tools and apps
Danfoss Ally™ App
With the Danfoss Ally™ App, you can control the heat throughout the house from one screen.
Download it for free in the App Store or Google Play and see for yourself how easy and intuitive it can be to have complete control of the floor heating.

Applications
You can get a system that fits exactly to your current installation. Check if the actuators are 230V or 24V. If they are 24V, they can be reused and you can get all the advanced options that the 24V system offers. But if you have 230V today, you can easily switch to 24V. Contact your local installer who will be able to advise you.
