Add a touch of contemporary elegance to your home with a 600 mm anthracite horizontal column panel radiator. The classic horizontal layout is perfect for installation under windows, while the textured matt anthracite finish provides a premium, designer look that complements modern interiors. Choose a Single Panel for a slimmer profile or a Double Panel when you need higher heat output for larger rooms.
Why this model?
- Efficient Heat Distribution: The wide column design ensures consistent and comfortable warmth across the room.
- Versatile Installation: The classic low-profile design fits perfectly under windows and integrates seamlessly into traditional room layouts.
- Built for Modern Living: The durable, scuff-resistant matt anthracite coating provides a long-lasting, premium finish.
Single vs Double Panel
- Single Panel: A slimmer profile; ideal for smaller rooms or where projection from the wall is a concern.
- Double Panel: Greater surface area provides a higher BTU output, making it ideal for larger rooms or areas with higher heat loss.
Sizing & BTU Guidance
Always size your radiator by BTU requirement rather than physical dimensions. Use our BTU Calculator to estimate the ΔT50 BTU output needed based on room dimensions, insulation, and glazing. You can meet the total BTU requirement with one larger radiator or by combining multiple radiators in the same room.
What’s Included
- Wall brackets & fixings
- Blanking plug & bleed valve
- Installation guide
Valves not included. Pair with angled or straight valves to suit your pipework; a thermostatic (TRV) set is recommended for finer temperature control.

Where it goes
Made for the wall under a window
A horizontal panel 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
Steel, coated to take knocks
Low-carbon steel under a textured matt anthracite coating — the texture is what stops scuffs showing on a radiator people walk past. Outputs are measured to British Standard BS EN 442, and the radiator carries a five-year guarantee.

Before you order
Valves are the one thing to add
Brackets, fixings, blanking plug and bleed valve are in the box; valves are not. Which pair depends on where your pipes come into the room, and a thermostatic set lets this room hold its own temperature rather than follow the rest of the house.
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, anthraciteFloor pipes
|
Pipes come up out of the floor under the radiator inlets and carry straight on into the valve. | £25.00 | View the straight trv, anthracite valve |
Angled TRV, anthraciteWall pipes
|
Pipes leave the wall horizontally. The valve turns them 90° into the radiator for you. | £25.00 | View the angled trv, anthracite valve |
Corner TRV, anthraciteWall 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, anthracite valve |
