What Are The Benefits?

A Low consumption radiator with the best Qualification Coefficient (C.A.) in Europe.

No Energy Wastage

With Harmony electric heating, there is 100% efficiency from your heating product, with no wastage. You have complete control over when and how the heat is distributed in your home. 

Most thermostats are accurate to within 2c, but the Harmony thermostat is accurate to within 0.05°c. For every 1°c increase in temperature, your heating cost can increase by as much as 10%, therefore having a more accurate thermostat will reduce your energy consumption as the room never overheats.

A Standalone Heating System

As each radiator in the Harmony range works individually, there’s no need for pipework or disrupting installation. There’s no need for annual maintenance and your radiator should last a lifetime. You can say goodbye to unsightly rust and to cold spots in your rooms from ageing radiators.

HARMONY radiators offer the most accurate temperature control in the industry, providing the best thermal stability and avoiding heat fluctuations. For every 1 degree increase in temperature, your energy bill increases by up to 10%.


The only heaters that work on a trickle charge technology and Heating Cruise Control. Once the room reaches temperature the HARMONY heaters drop their power and heat the room using the energy stored in the Silicon Battery.


Control your Harmony heaters from your smartphone. Monitor your energy usage in real time. Using Geolocation, it can switch your heaters on and off when you leave the house or return home. Also compatible with Amazon Alexa and Google Home.

Heaters and Sunamp Hot Water

The 6 heaters are great – easy to control – and are miles better than the previous storage heaters…however the Sunamp hot water is the absolute star of the show.

Had my radiators fitted last week

In respect of the the installation, this was 5*. My 1st experience of tidy and methodical working. The installers were awesome, and went well in excess of the extra mile.



Best heating decision I’ve made

They heat up very quickly in comparison to the old night storage heaters. The controls are very easy to use, holds the room temperature at whatever I set it to, and accurately.
