If you have an ageing standard radiator sitting under your living room window, the Kartell K-Rad Aspen 600 x 1140mm Textured Grey Double Horizontal Radiator is its.
If you have an ageing standard radiator sitting under your living room window, the Kartell K-Rad Aspen 600 x 1140mm Textured Grey Double Horizontal Radiator is its natural upgrade. It matches the footprint of most older 1100–1200mm radiators exactly, so it drops straight into existing pipework with minimal disruption. The double panel construction delivers a confident 6,223 BTU (1,824W) — enough to heat a substantial living room or open hallway as a standalone heat source — while the deep matt textured grey finish transforms what was once a purely functional fitting into a design statement. SKU: ASP60-115DA.
Pipe centres sit at 1140mm — a common dimension on older UK installations — making this a straight swap with no floor pipe alterations required.
Two panels of oval tube steel heat the room faster than a single panel equivalent, reducing boiler run times and improving energy efficiency.
The deep matt powder coat resists fingerprints and everyday knocks while coordinating beautifully with anthracite window frames and contemporary grey kitchen units.
At 600mm high it clears standard sill heights and complies with building regulations for sub-window installation, keeping natural light unobstructed.
All manufacturing defects covered for 5 full years from purchase. Kartell UK is one of the UK’s most established heating brands with a strong warranty record.
Wall brackets, screws, rawl plugs, air vent and blanking plug all supplied in the box — no additional fixing kit required.
