Where it goes
Made for the wall under a window
A horizontal radiator at 600 mm goes where radiators have always gone — under the window, along the wall behind a sofa, below a worktop run. Cold air falling off the glass meets the heat on its way down, which is the whole reason that spot became the convention.

Build
Oval columns in gloss white
Elliptical columns in 1.5 mm mild steel under a gloss white powder coat — a softer profile than a flat panel, and a surface that stays bright with a wipe. Outputs are measured to British Standard BS EN 442, and the radiator carries a five-year guarantee.
- 1.5 mm mild steel, curved oval columns
- Gloss white powder-coated finish
- Outputs tested to BS EN 442
- 5 year guarantee
Before you order
Valves are the one thing to add
This radiator runs on central heating and is supplied without valves, so a pair goes on the order with it. Which pair depends on where your pipes come into the room, and a thermostatic set lets this room hold its own temperature.
Which valve fits your pipework?
All three hold this room at the temperature you set on the dial, independently of the rest of the house. What changes between them is how your pipes come into the room.
| Valve | Choose it when | Price | Product page |
|---|---|---|---|
Straight TRV, whiteFloor pipes
|
Pipes come up out of the floor under the radiator inlets and carry straight on into the valve. | £36.00 | View the straight trv, white valve |
Angled TRV, whiteWall pipes
|
Pipes leave the wall horizontally. The valve turns them 90° into the radiator for you. | £36.00 | View the angled trv, white valve |
Corner TRV, whiteWall pipes
|
Also wall pipes, but tucked in tighter — the body sits close to the wall and stays out of the way. | £36.00 | View the corner trv, white valve |
