Colenzo is a steel multi-column radiator with the classic look of a traditional column radiator and the speed and lightness of steel. A black finish turns the radiator into a design feature, striking against white, grey or boldly painted walls.

Choose from 3 sizes with outputs from 2,884 to 4,532 BTU/hr at ΔT60, so you can match the radiator to the room. It is made from steel, pressure tested to 10 bar, and its large surface area makes it a good choice for bigger rooms. Radiator valves are sold separately.

Sizes and heat outputs

Size (H x W) Output BTU/hr (ΔT60) Output watts (ΔT60) Weight
600x650mm 2,884 845 15.68kg
600x830mm 3,708 1,087 19.8kg
600x1010mm 4,532 1,328 24.2kg

Outputs are quoted at ΔT60, the manufacturer's test standard. Many UK comparisons use ΔT50, which gives a lower figure (roughly a fifth less), so allow a little extra output when sizing for a modern low-temperature or heat pump system.

Frequently asked questions

How do I choose the right size?
Work out the heat your room needs with a BTU calculator (it depends on room size, windows and insulation), then pick a size whose output meets or slightly exceeds it. If you are running a lower flow temperature, allow extra.

Which valves do I need?
You will need a pair of 15mm radiator valves. For a matching look choose manual modern radiator valves in matt black or thermostatic control with the designer TRV twin pack in matt black. See all radiator valves.

Can it stand on the floor?
Yes, add the Colenzo column radiator feet to free-stand it.

Other finishes?
Also available in white.

Other versions?
The same design also comes as a vertical 2 column radiator, horizontal 3 column radiator and horizontal 4 column radiator.

Help choosing

Size a radiator by heat output (BTU), not by how it looks on the wall.

How much heat does your room need?

Enter your room size to see the heat output you need.

  1. Match the output to the room. Use the BTU figure from the calculator. In a bathroom, a towel rail alone often heats a small room; bigger rooms may need a radiator too.
  2. Check your connections. Measure the gap between your pipes and choose valves to suit: angled, straight or corner (see the valve helper on our valve pages).
  3. Heat pump? At the lower water temperatures heat pumps run at, expect roughly half the listed output.
  4. Summer use. Central heating rails only warm up when the heating is on. A dual fuel kit adds an electric element where the rail supports it.

Still not sure? Send us your measurements and we'll check for you.

Questions people ask

What does BTU mean?
BTU (British Thermal Units) is the heat output. The higher the figure, the more heat it gives. Use the calculator under Help choosing to see what your room needs. Outputs are quoted at ΔT50.
How much heat do I need?
As a rough guide allow around 100W per square metre of floor in an average room, and more for older properties, high ceilings, large windows or north-facing rooms. Outputs are quoted at ΔT50.
Are valves included?
Radiators are supplied without valves unless the description says otherwise. Add a pair to suit your pipework.
Will it work with a heat pump?
Yes, but heat pumps run at lower water temperatures, so a radiator gives out roughly half its ΔT50 figure. Size up accordingly.
What are pipe centres?
The distance between the two connections. Measure between your pipes and compare it with the pipe centres, allowing for the valves.
