One of the UK’s best-selling oval tube designer vertical radiators. Gloss white finish, mild steel construction, 55mm wall projection. 5 year Kartell manufacturer guarantee. All fixings included.
The distinctive oval tube construction gives better heat circulation, a slimmer 55mm profile, and a far more premium aesthetic than standard flat panel radiators at similar price points.
At 1800mm tall and just 420mm wide it fits neatly in narrow hallways, beside doors, between windows, and in bathrooms where a conventional horizontal radiator simply will not fit.
Heat output tested and certified at Delta T60. Suitable for large bathrooms, single bedrooms, and hallways with average insulation.
One of the strongest guarantees available at this price point. Registered directly with Kartell UK and covers all manufacturing defects from date of purchase.
The distinctive oval tube design is both a visual statement and a functional advantage — greater surface area than round tubes means more efficient heat transfer per tube.
Weighing 16.8kg empty with all wall brackets, fixing screws, wall plugs, air vent and blanking plug supplied. Add valves and it is ready to hang.
