Open-plan kitchen-diners, large bedrooms and bay-windowed reception rooms often need generous width coverage without aggressive heat output — and that is exactly where the Kartell K-Rad Aspen 600 x 1440mm Textured Grey Single Horizontal Radiator earns its place. The 1440mm single panel delivers 4,227 BTU (1,239W) across a wide wall span, providing even background warmth without overheating well-insulated modern rooms. At just 55mm deep it sits closer to the wall than a double, reducing visual weight on already generous wall runs. SKU: ASP60-145SA.
At 1440mm wide and 4,227 BTU, this radiator heats a broad wall area evenly — ideal for well-insulated modern homes or rooms supplemented by underfloor heating where a double panel would create uncomfortable spikes in temperature.
The 55mm single panel depth is 24mm shallower than the double panel equivalent, making it the better choice where kitchen units, sofas or fitted furniture run close to the radiator wall.
A 1440mm radiator in textured grey creates a long, deliberate horizontal feature — a far more considered look than multiple smaller white radiators scattered around the same room.
In rooms with wet underfloor heating providing the base load, this single panel radiator provides the quick-response top-up heat that UFH systems cannot deliver rapidly.
Designed to sit beneath standard window sill heights in compliance with UK building regulations, allowing glazing to reach near to floor level without blocking it.
The full 5 year manufacturer guarantee applies equally to single panel models — this is not a compromise product, it is a deliberate sizing choice.

When to use: Pipework comes straight up through the floor directly into the bottom tapping at either end of the radiator.
When to use: Pipework comes horizontally out of the wall at either end and connects to the side tappings of the radiator valves.

The SA (Single) has a 55mm depth and outputs 4,227 BTU. The DA (Double) is 79mm deep and outputs 7,861 BTU. Both share identical 1440mm pipe centres and external dimensions — only the depth and BTU differ.
For a large UK master bedroom of around 18–25m² with good insulation and double glazing, 4,227 BTU is generally sufficient. For rooms with high ceilings or poor insulation, consider the double panel. Use the BTU Calculator to confirm.
The ASP60-145SA weighs 17.28kg — significantly lighter than the 32.64kg double panel, making wall fixing more straightforward. Standard solid wall fixings are appropriate.
Yes — this is a common and effective combination. The UFH provides steady background warmth and the radiator provides faster response when temperatures need a quick boost, particularly on cold mornings.
Pipe centres are 1440mm. Wall to pipe centres is 60mm. Valves fit at either end of the radiator in the standard horizontal configuration.
The textured grey matt finish is one of the most popular choices for open-plan kitchen-diner spaces precisely because it coordinates with dark cabinetry, stainless steel appliances and polished concrete or slate flooring without competing for attention.
