When searching for a radiator with a simply beautiful aesthetic there is no need to look any further than the Harmoni Duero. Its sleek design favours a white finish and upward facing grille, resulting in the model effortlessly dissolving into any residential or commercial setting.

Under the bonnet, the Duero features the most up-to-date electric radiator technology. It has full control over its environment with its incredibly accurate electronic thermostat measuring room temperature to a quarter of a degree. The readings are easily visible and accessible through the Duero’s blue front-facing LCD screen.

It offers total manual control because of its digital buttons and infrared remote control. The remote gives access to the pre-programmed modes installed in the Duero and also all your own personalised settings.


The Harmoni Duero has an inbuilt 24/7 timer so your heating is always ready whenever you need it. Its energy-saving technology optimises your heating solution’s effectiveness, saving you time and money.

Harmoni’s open window technology monitors the ambient temperature of the room and is able to react to any rapid variation. The Harmoni will pause its cycle until the temperature stabilises and then correct to suit your needs. This ensures a minimisation of energy wastage and a maximisation of efficiency.

The Harmoni Duero is Lot 20 compliant and has an IP24 rating.


The pre-installed modes the Duero features include eco, comfort and anti-frost. It also supports four editable programs. As a clay filled radiator, the radiator can fluctuate between temperature settings quickly and its aluminium shell ensures its surface temperature is reduced.

The Duero is incredibly quiet and its clay core ensures a comforting heating solution. The Duero is designed to be stylish, minimalist and utilises recent technology to lower your carbon footprint and energy consumption. The Duero drastically increases the comfort offered by your property whilst discreetly disappearing into the background, no thought needed.

The Duero offers a pilot mode upon request, so after a user-friendly installation you can kick back and relax and let Harmoni take over. If anything was to happen we offer a ten-year warranty on every Duero purchased.

So far so good, managed to programme them myself too! Kicks our lovely heat, stays hot for some time after they're switched off. Look very smart and tidy too on the wall.

Efficient service, helped with alternative as what I wanted was no longer available

Thank you very much for taking the time to leave such great feedback.
