When a compact wall has to heat a stubborn room - a north-facing snug, a box room over the garage, a hallway that eats warmth - the third column earns its place. This 650mm black three-column packs 4,088 BTU (1,198W) at Delta T60 into the same footprint as a two-column, simply by running deeper at 100mm. Fourteen sections keep the traditional rhythm; the matt black finish keeps it current.
Laser-welded mild steel, 10 bar pressure testing and a five year Kartell guarantee are standard across the Laser Klassic range. Brackets and fixing kit are boxed with the radiator; pair with a thermostatic valve to hold small rooms at a steady temperature without cooking them.
Range photography is for illustration - the number of sections varies with the size ordered. This listing is the 600 x 650mm 3 column model with 14 sections. Dimension drawing included in the gallery.
The right radiator is the one sized to the room, not the biggest that fits the wall.
| Output at Delta T60 (Kartell published) | 4,088 BTU / 1,198W |
|---|---|
| Output at Delta T50 (calculated, EN442 factor) | approx. 3,226 BTU / 945W |
| Typical room coverage | roughly 7-10 square metres in an average UK home |
Coverage is a guide only - insulation, glazing area and ceiling height change the sums. Use a BTU calculator with your room dimensions before ordering, and size up slightly for north-facing or draughty rooms.

Installation is a routine job for any plumber or competent DIYer used to hanging radiators.
Valves are not included. You need a pair: one wheelhead or thermostatic (TRV) valve plus one lockshield. Angled valves suit pipework rising from the floor; straight valves suit wall-fed pipe runs.
See our radiator valves range - the Kartell TRV and lockshield twin packs pair perfectly.
Orders are picked from live UK stock. Radiators are palletised or double-boxed and checked before dispatch - please inspect on arrival and note any transit damage with the driver.
