The D Series electric WiFi radiator is the first in the world to include a built-in WiFi module that allows you to connect an entire installation without intermediate gateways. These high power WiFi modules can reach up to 100m without obstacles and our servers have a reliability of over 99%. With the free Rointe Connect app, your smartphone, tablet or PC will give you easy control of your installation. You can adjust temperatures, lock the products remotely and control the expenditure on a daily basis from home, your office or on the go. With the app, you can divide the property into rooms, floors or bespoke zones and can control to suit your needs. You can program activation and shutoff of your radiators at whatever time you desire, maximising your energy savings. Plus the app allows you to view real-time energy consumption reports by day, month or year along with the ability to configure different kWh prices for each hour of the day. It will also send warnings, notifications and recommendations direct to your device so you can save on consumption. They also work with Amazon Alexa.


The D Series is an advanced wall-mounted radiator boasting our patented energy-smart Fuzzy Logic Energy Control technology and functions, alongside high purity aluminium and high heat transfer thermal fluid (oil-filled) for the perfect balance between efficiency, style and comfort, without increasing your costs. With a new curved design, front dissipation wings that favour natural air convection and 24/7 programming, the D Series WiFi radiator is designed with you in mind.

Fuzzy Logic Energy Control

Our most advanced low consumption technology. Thanks to Fuzzy Logic technology, the average power consumed represents only 38% of its nominal power. It improves energy required to maintain a stable temperature, analysing thermal variations with an accuracy of ± 0.25ºC.

E·life technology

Patented by Rointe, it's the first direct communication system with real-time synchronization in electric heating. It allows a high speed connection without gateways between the Rointe Connect app and your heating product for complete control.

WiFi Inside

An integrated WiFi module, built into your Rointe heating product for direct data transmission between each product and your domestic
WiFi network. You won't need intermediate devices or additional configurations.

Compatibility with Amazon Alexa

Amazon Alexa

You can now control your connected products through Rointe Connect and Alexa. It makes managing your smart heating system even easier.​ Using just your voice, you can remotely control your Rointe connected heating system.

⁽¹⁾ In tests performed by independent laboratories (under the same parameters), a radiator with Fuzzy Logic Energy Control technology and another with Optimizer Energy Plus were compared. A difference in energy consumption of 6.3% was obtained. This saving allows the radiators with Fuzzy Logic Energy Control to use an average power of only 38% of the nominal power. We define this as the equivalent consumption coefficient. If we multiply the nominal power by the equivalent consumption coefficient, we obtain the effective power.

⁽²⁾ Once steady working rate achieved.

Watch our installation video to learn how easy it is to install a Rointe radiator. If you’d prefer to use a Rointe Trusted Installer instead, use our handy locator here.

Radiator installation recommendations:

  • Rointe radiators are designed to be wall-mounted, with fixings, brackets and a template supplied as part of the product.
  • Rointe radiators must be positioned vertically, but not under a window. This would affect the thermostat reading, potentially causing excessive consumption.
  • Rointe radiators sized for a particular room should not be installed in another unless the conditions (such as size, ceiling height etc.) are extremely similar.
  • Rointe radiators are best placed on a wall away from drafts like doors and with sufficient space so the radiator won’t be obscured by furniture. This allows the best natural convection cycle for even and efficient heat.
