Styles and sizes

Three heights, fifteen sizes, and every one of them only 7cm deep. We’ll work out the right size for each room at your free survey, so you never pay for more heater than the room needs.

The radTherm range

Three heights, one for every wall

All three share the same German engineering, fluted steel body and heat-retaining core. The only difference is the shape, so you can pick whichever fits the space.

Colours and finishes

White as standard, or 900+ colours to choose from

Every radiator is powder-coated in white as standard, with anthracite grey as a set option. If you’d rather match a wall, a skirting board or a piece of furniture, each radiator is made to order in Germany, so it can be finished in any of 900+ colours.

Bring a colour you love to the survey and we’ll help you find its closest match.

Controls

Choose how you control it

Every size comes with a choice of four thermostats, from two simple buttons to full app control of every room.

DSM thermostat

App control through a small interface box, with room-by-room schedules, energy use history and a long wireless range. Best for homes heating several rooms.

DSD thermostat

Connects straight to your Wi-Fi with no extra box. Ideal when you’re only fitting a few radiators.

D-Basic thermostat

Two buttons on the radiator itself, for anyone who’d rather not use an app. App control can be added later over Wi-Fi.

RF receiver

A built-in radio receiver, so the radiator can be run from a separate wireless wall thermostat.

Smart control and the app

Options

For bathrooms and special rooms

Towel rails

Electric towel warmers in white, matt black or chrome, to go with a bathroom radiator or on their own.

Splash-proof models

Every height is also made in an IPX4 version, protected against splashing water for bathrooms and utility rooms.

Low surface temperature

Low-temperature models run with a cooler surface, for children’s rooms and anywhere a hot radiator is a worry.

“We were pleasantly surprised that we didn’t need as many radiators as we thought, yet still had enough to heat all the rooms exactly as we wanted.”
Louisa Chanter Tavistock, Devon
