Overview

Dining rooms deserve a radiator with presence, and eighteen white three-column sections provide exactly that: 5,256 BTU (1,540W) at Delta T60 from an 830mm frame with proper Edwardian depth. Guests notice it the way they notice a fireplace - and in winter it does the fireplace's job, holding steady warmth through long meals.

The 100mm column depth plus 30-40mm stand-off still projects under 140mm - shallower than a sideboard. Laser-welded mild steel, gloss white powder coat, 10 bar testing, five year Kartell guarantee, brackets and fixings included. Cross-head valves in aged brass are the finishing touch.

Range photography is for illustration - the number of sections varies with the size ordered. This listing is the 600 x 830mm 3 column model with 18 sections. Dimension drawing included in the gallery.

Sizing Guide

Start with the room, not the radiator: output should match the space's heat loss.

Output at Delta T60 (Kartell published)5,256 BTU / 1,540W
Output at Delta T50 (calculated, EN442 factor)approx. 4,147 BTU / 1,215W
Typical room coverageroughly 9-13 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

Fitting follows standard UK two-pipe practice and holds no surprises for an installer.

  • Connects to a standard UK two-pipe central heating system.
  • Tappings sit at the bottom on opposite ends, approx. 830mm apart; pipe up through the floor or along the wall to suit.
  • Brackets hold the columns 30-40mm off the wall - allow 130-140mm from wall to the front face.
  • Empty weight is 28.3kg: fix into masonry or studwork, not plasterboard alone. Optional Kartell floor feet carry the weight on stud walls or solid floors.
  • Flush the system and dose inhibitor after fitting, as with any new radiator.
Valves & Extras

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.

  • Traditional cross-head or antique-style valves complete the period look this radiator is designed for.
  • A TRV keeps larger rooms at a set temperature and trims running costs.
  • Optional Kartell floor feet (white or black to match) add about 120mm and take the weight on suspended floors.

See our radiator valves range - the Kartell TRV and lockshield twin packs pair perfectly.

Delivery & Returns

  • Questions on access or timed delivery? Call 01282 429061 before ordering.
Frequently Asked Questions
No - like almost all designer radiators the valves are chosen separately so the finish suits your room. You need one wheelhead or thermostatic valve and one lockshield valve. The tappings are at the bottom on opposite ends approximately 830mm apart.
Yes on any standard indoor wet central heating system, including kitchens. For bathrooms keep it outside splash zones; the powder coated finish handles normal humidity without trouble.
Kartell guarantees the Laser Klassic for five years; every radiator is pressure tested to 10 bar before it leaves the factory. Register the product with Kartell UK after purchase to activate the cover.
As a guide 1,215 watts at Delta T50 will comfortably heat roughly 9-13 square metres in a typical UK home. Poor insulation, large glazing or high ceilings increase demand, so always size with a BTU calculator using your room's real dimensions.
