A full-height double panel designer vertical radiator in gloss white. Available in three widths delivering between 4,664 and 8,397 BTU. Select your width from the dropdown above. 5 year Kartell UK guarantee. All fixings included. Free delivery on orders over £500.
The double panel delivers nearly double the heat of the single panel version from the same wall width. Three widths available to suit any room. Use the BTU Calculator tab to confirm.
Standing at 1800mm tall, the Aspen makes a bold design statement while maximising heat output. The oval tube design provides a premium look over standard flat panel alternatives.
The gloss white finish suits all interior styles from traditional to contemporary. Matches standard UK plumbing fittings and radiator valves for a seamless installation.
Slightly deeper than the single panel at 55mm, but the additional heat output is substantial. Ideal where wall space is available and maximum warmth is the priority.
Registered directly with Kartell UK. All wall brackets, fixing screws, wall plugs, air vent and blanking plug included as standard. Pressure tested to 7.8 bar.
Need a slimmer profile? The Aspen 1800mm Single White delivers from 2,392 to 4,309 BTU at just 55mm deep.
