A premium matt textured grey vertical designer radiator (also known as anthracite) delivering 2,897 BTU from a slim 420mm body. 1600mm height, single panel construction, 52mm depth, 18.47kg. 5 year Kartell UK manufacturer guarantee. All fixings included.
If you have a hallway, kitchen or compact living room that needs a slim vertical radiator with a darker, more contemporary look, the Kartell K-Rad Boston 1600 x 420mm Anthracite Vertical Single Designer Radiator is the natural choice. The slim 420mm body delivers 2,897 BTU (849W) from a footprint that occupies almost no floor space — ideal for narrow walls between doorframes and kitchen units. The matt textured grey finish brings industrial-style designer character to compact rooms. SKU: BOS1600-410A.
The matt textured grey powder coat is the on-trend finish for 2026 UK interiors — pairs beautifully with grey kitchen units, anthracite door furniture and concrete-effect tiles.
The 420mm body is one of the slimmest vertical designer radiators on the UK market — ideal for narrow walls behind doors, beside chimney breasts, or between fitted units.
Despite the slim profile, the 7 flat-tube design delivers genuine heat — suitable as the sole heat source for hallways, small bedrooms and compact rooms in average UK insulation.
Identical dimensions to the white BOS1600-410W means you can mix anthracite in main rooms with white in bedrooms or bathrooms, keeping the same designer language throughout.
Unlike high-gloss whites that show every smear, the matt textured grey finish wipes clean easily and is forgiving in busy hallways and family kitchens.
Full coverage on the genuine 5 year guarantee — registered direct with Kartell UK in your name. This is the original Kartell-branded Boston, not a re-branded copy.

Valves are not included and must be purchased separately. We recommend matching Kartell K-Design Textured Grey TRV twin packs to complement this radiator perfectly. Select your pipework type below.
When to use: Pipework rises vertically from the floor and connects to the side tappings of the radiator. This is the most common UK installation type for vertical radiators.
When to use: Pipework rises directly from the floor into the bottom tappings in a straight vertical line.
When to use: Pipework rises behind the radiator and connects to the bottom tappings at an angle, giving a clean concealed finish.

Kartell describe this finish officially as Textured Grey, which is what most UK plumbers and merchants call “anthracite”. The actual finish is a deep matt charcoal grey with a fine textured powder coat — closest to RAL 7016. Pairs beautifully with warm whites, oak, brass and concrete-effect tiles.
Yes — at 420mm physical width, the Boston 1600 x 410mm sits comfortably in narrow gaps between most UK doorframes, chimney breast pillars and fitted kitchen units. Allow approximately 60–100mm extra clearance either side for valve bodies and pipework.
For a typical UK hallway, small bedroom or compact home office of 8–12m² with average insulation, 2,897 BTU is generally sufficient as the sole heat source. Use the BTU Calculator above to confirm against your specific room dimensions.
No — valves are sold separately. We recommend matching Kartell K-Design Textured Grey TRV twin packs for tonal consistency, or polished chrome valves for a contrast accent. See the Valves tab above for angled, straight or corner options.
Yes — this is the original Kartell-branded Boston (BOS1600-410A, EAN 5060168223821) supplied through Kartell UK’s authorised distribution. Some retailers re-brand the same Kartell radiator under their own house name; we don’t. You get the genuine Kartell guarantee, registered in your name.
