D Series – 5 elements electric radiator (white)

Quite possibly the best electric radiator in the world.

  • Finish:                             White RAL 9016
  • Reference:                      DIW0550RAD
  • EAN Code:                     8436045913715

The D SERIES radiator is the first in the world to incorporate an internal Wi-Fi module. It allows the user to control all the features of the product together or individually from a smartphone, tablet or PC with the free Rointe Connect mobile app. With a new curved design, front dissipation wings that favour natural air convection and made from high quality 100% aluminium, these radiators are designed with you in mind.

Customer satisfaction always comes first for us. That's why the D Series electric radiator includes 20 years guarantee on the aluminium body and 3 years on the electrical components.

* Average surface temperature obtained with the radiator temperature set at 21ºC.

**The effective power of the D Series radiator is 38%. This value has been obtained in tests performed by independent technology centres in a climatic chamber, by comparing two Rointe radiators under the same parameters (one with Fuzzy Logic Energy Control and the other with Optimzer Energy Plus. Optimizer Energy Plus is the first technology patented by Rointe that obtained a power of 40% of the nominal power of the product in which it was installed.  In this comparison, we observed a consumption difference of 6.3%, which reduces the effective power obtained with the previous technology, Optimzer Energy Plus. This, in turn, deduced that Fuzzy Logic Energy Control technology reduces the effective power of the radiator up to 38%.
