A premium gloss white vertical designer radiator delivering 3,733 BTU from a slim 490mm body. 1800mm height, single panel construction, 52mm depth, 23.19kg. 5 year Kartell UK manufacturer guarantee. All fixings included.
The most popular full-height designer radiator in the Boston range, the Kartell K-Rad Boston 1800 x 480mm White Vertical Single Designer Radiator is the size most customers pick when they want a striking floor-to-ceiling design feature with serious heat output. The 490mm body delivers 3,733 BTU (1,094W) from a slim 52mm profile — perfect for living rooms, hallways and open-plan spaces. The gloss white finish makes a real visual statement. SKU: BOS1800-480W.
At 1800mm tall and 490mm wide, this is the most-chosen full-height Boston in the white range — the size most customers pick for living rooms, hallways and modern open-plan spaces.
The 8-tube single panel delivers enough heat for typical UK living rooms up to 16m² with average insulation — the natural choice when you want one striking radiator to do the job of two horizontal panels.
Despite the dramatic full-height proportions, the single panel construction sits just 52mm from the wall — preserving floor space and keeping the room looking open.
The premium gloss white powder coat (RAL 9003) is durable, scratch-resistant and brightens interiors — making the most of the full-height vertical design.
The 23.8kg weight reflects the solid mild steel construction — this radiator feels and looks like a genuine designer product, not a budget compromise.
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.

Yes — the 1800 x 480mm is one of our best-selling sizes in the white Boston range, precisely because it suits typical UK living rooms (14–16m²). The 8-tube full-height single panel delivers 3,733 BTU which comfortably heats most average-insulated UK living rooms with double glazing.
Allow approximately 1900mm tall x 600mm wide total wall space — the radiator itself is 1813mm tall and 490mm wide, plus clearance for valves and pipework above and below. Pipe centres are 440mm.
This radiator projects 52mm from the wall — one of the slimmest profiles in the Boston single panel range, helping preserve floor space and giving a clean, unobtrusive appearance.

Yes — this is the original Kartell-branded Boston (BOS1800-480W, EAN 5060168223739) 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.
Yes — the Boston operates well at lower flow temperatures typical of modern air-source heat pump systems. At heat pump flow temperatures (often Delta T30 or T40) the BTU output will be lower than the quoted Delta T60 figure — call 01282 429061 for sizing advice.
