Why choose the Aspen 1800mm Double Textured Grey?
1

Double Panel — Up to 8,397 BTU

The double panel delivers nearly double the output of the same-size single panel from the same wall width. The 79mm depth is the only trade-off.

2

1800mm Full Height

The full-height 1800mm model is the statement choice — making a strong visual impact while maximising heating surface area.

3

Premium Textured Grey Finish

Matt powder coat. Scratch-resistant and far more characterful than standard gloss white. Kartell UK's official current colour name.

4

Oval Tube Designer Construction

Greater surface area than round tubes for more efficient heat transfer. Premium aesthetic over standard flat panel radiators.

5

5 Year Kartell UK Guarantee

All wall brackets, fixing screws, wall plugs, air vent and blanking plug included. Registered directly with Kartell UK.

Which radiator valves do I need?

Valves are not included and must be purchased separately. For this textured grey radiator we recommend Textured Grey TRV valves to match the finish. Select your pipework type below.

Angled Textured Grey Valves

When to use: Pipework rises vertically from the floor to the side connections. The most common UK installation type.

Straight Textured Grey Valves

When to use: Pipework rises from the floor and connects directly to the bottom tappings in a straight vertical line.

Corner Textured Grey Valves

When to use: Pipework comes horizontally out of the wall and connects to the side connections of the radiator.
