Welcome to radTherm
21st Century heating
“Dedicated to the electrification of heat.”
A Shift in the breeze for heating: radTherm Leads the Charge.
The landscape of home heating is undergoing a seismic shift. The phase-out of fossil fuel systems is no longer a distant threat, but a driving force for innovation. At radTherm, we see this not as a challenge, but as an opportunity – an opportunity to continually redefine comfort and redefine efficiency.
For generations, homes have relied on traditional gas and oil boilers or bulky, inefficient night storage heaters. While these systems served their purpose, their time is undeniably coming to an end. The environmental impact is undeniable, and the push for cleaner energy sources is paramount.







‘Magmatic’ Heat Retention Core
Our unique combination radiators are designed to store the heat directly into the Magmatic heat–retention tablets, without any loss of energy.
The metal ribs on the radiator form a six times greater surface area than a normal radiator. As a result of this, approximately 50% radiant heat as well as 50% convected heat is created, to give a much more consistent temperature throughout the room, from floor to ceiling.
The radiators are unique due to the metal ribs being individually spot welded which prevents any noise during the heating up and cooling down cycle. When the radiators have achieved their required temperature the thermostat will cut the power to the radiator.
The radiator will continue to provide heat (that has been stored in the Magmatic tablets) for up to 45 minutes with no further use of electricity.
The Radiators will use approximately 12-15 minutes of electricity per hour, depending on the building fabric and outside temperature.
The heating conductors are produced from high quality chrome-nickel steel (resistant to scaling up to 1100 °C) which are moulded into the Magmatic tablet, reducing the risk of corrosion.
The contacts inside the radiators are protected with heat-shrinkable insulated sleeves to ensure optimum safety. Multiple thermocouples within each radiator provide overheat protection for additional safety.

Total Reliability
Boasting a modern, robust technology which requires no maintenance or servicing. All of our radiators are precision engineered and made to order in Germany and come with a genuine 30-year guarantee.
Economical
100% energy-efficient, with advanced, patented ‘Magmatic’ heating core is highly effective at storing heat, so the unit only requires a small trickle of electricity to maintain the heat
Total Control
With an individual thermostat so you can choose the precise temperature of each room/area and what time you need them. You can control the complete system room by room/zone by zone as you wish.
Modern and Stylish
A stunning, slimline design with sleek, curved flutes which are aesthetically pleasing. We manufacture your radiators to order, therefore they are available in a range of sizes and in over 900 colours!
Built For Efficiency
Our ingenious, fluted design multiplies each radiators effective surface area by X6 - spreading warmth evenly throughout the room using natural convection and radiant heating, while the high-grade Magmatic core distributes heat across the whole surface.
