Laser Klassic Collection
Kartell K-Rad Laser Klassic
The Laser Klassic is Kartell's take on the traditional column radiator: laser-welded mild steel tubes in the proportions of an original Edwardian column, built for modern sealed systems and pressure tested to 10 bar. This is the current 2026 generation - we list Kartell's official output data for every size, which many retailers still have wrong.
The collection spans 25 models: two and three column verticals at 1800mm high, two, three and four column horizontals at 600mm high, in gloss white and matt black RAL 9004. Widths run from a slim 335mm to a room-filling 1190mm, with outputs from 2,884 to 8,710 BTU at Delta T60.
- Free UK mainland delivery on every Laser Klassic
- 5 year Kartell guarantee (register after purchase) and 10 bar pressure testing
- Wall brackets and fixing kit supplied; optional Kartell floor feet available
- Dimension drawings and room-size guidance on every product page
