Overview

A tower of heat on the footprint of a bookcase spine: 335mm wide, three columns deep, 5,404 BTU (1,584W) at Delta T60. Where the slim two-column version warms a hallway, this one heats it properly - the extra 100mm-deep column bank adds nearly forty percent more output without claiming another millimetre of width. Entrance halls with a single narrow pier of wall are its natural habitat.

Construction is laser-welded mild steel in gloss white powder coat, pressure tested to 10 bar and guaranteed for five years by Kartell. Brackets and fixings are in the box. Its seven sections mirror the proportions of original Edwardian columns almost exactly.

Range photography is for illustration - the number of sections varies with the size ordered. This listing is the 1800 x 335mm 3 column model with 7 sections. Dimension drawing included in the gallery.

Sizing Guide

A radiator only looks right when it heats right, so check the numbers first.

Output at Delta T60 (Kartell published)	5,404 BTU / 1,584W
Output at Delta T50 (calculated, EN442 factor)	approx. 4,264 BTU / 1,250W
Typical room coverage	roughly 10-13 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

Any heating engineer will treat this as a straightforward swap or first fix.

Connects to a standard UK two-pipe central heating system.
Tappings sit at the bottom on opposite ends, approx. 335mm 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 31.25kg: 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.

Frequently Asked Questions

The columns are 100mm deep and the brackets hold the body 30-40mm off the wall, so allow roughly 130-140mm from wall to the front face.

Gloss white powder coat over mild steel. It is a factory powder coat, considerably tougher than wet paint, and covered by the five year Kartell guarantee. Special finishes including anthracite and raw metal are available in the wider Laser Klassic range.

Kartell rates it at 5,404 BTU per hour (1,584 watts) at Delta T60, the standard European test condition. At the more conservative Delta T50 condition used by many UK sizing guides that equates to approximately 4,264 BTU (1,250W) - a calculated figure using the EN442 correction factor.

The radiator itself in Gloss White with wall-mounting brackets, a fixing kit and instructions. Radiator valves are sold separately. Optional Kartell floor feet are available if you prefer floor-standing support.
