D-Basic

Two buttons, no app needed

DSM

Full programming and smart control

D-Basic or DSM: which suits you?

Both controls come with an industry-leading 5-year manufacturer warranty and work with the same free radTherm® app.
No app needed

D-Basic thermostat

The D-Basic is built for straightforward, no-fuss operation. Press PLUS to raise the temperature by 1 °C and MINUS to lower it. That’s it.

If you ever want scheduling, connect the heater to your Wi-Fi and add it to the free radTherm® app. Bluetooth Connect makes set-up easy, and no extra devices are needed.

  • Two buttons directly on the radiator
  • No menus, no learning curve
  • Add app control later if you want it
Full smart control

DSM thermostat

The DSM is the smart option. Four buttons on the radiator give you full 24/7 weekly programming with adaptive start, so each room reaches temperature exactly when you need it, plus Comfort, Economy and Anti-Freeze presets.

We know not everyone wants to use an app, so every setting can be made on the radiator itself. If you do want remote control, the radTherm® app does that too, with Amazon Alexa and Google Home voice control.

  • Full weekly programming on the radiator or in the app
  • Adaptive start and open-window detection
  • Hands-free control with Alexa or Google Home

Why radTherm®?

Class-leading electric heating

A combination of natural convection and radiant heat from the fluted design gives gentle, even warmth, much like central heating.

Total reliability

Modern, robust technology with no maintenance or servicing. Every radiator is precision-engineered and made to order in Germany, with a genuine 30-year guarantee.

Economical

100% energy-efficient. The patented heat retention smart core stores heat so well that the radiator needs only a small trickle of electricity to maintain the temperature.

Total control

Every radiator has its own thermostat, so you choose the temperature and times for each room: simple buttons on the radiator, or smart control from your phone.

Modern and stylish

Slim designs only 7 cm deep, made to order in a range of sizes and finishes to suit your home.

Built for efficiency

Our ingenious fluted design multiplies each radiator's effective surface area by six, while the patented smart heat retention core distributes heat across the whole surface.
