Stelrad Double Panel Single Convector (P+) 600mm High Radiator

Made by Stelrad, from their Compact steel panel radiator range.

For a standard 600mm high radiator that does not stick too far out from the wall, look at this Double Panel Single Convector. It is a Type 21 or P+, with two panels and one convector between them.

Why go for a 600mm double panel single convector

600mm is the most common radiator height in UK houses, so it often lines up with existing pipework when you replace an old one. A Type 21 gives more heat than a single panel but is slimmer than a Type 22. So it suits hallways and narrow rooms where people brush past the radiator.

• Height: 600mm
• Lengths: 400mm to 1200mm in 100mm steps, plus 1400, 1600, 1800, 2000 and 2200mm
• Two panels, single convector (Type 21)
• Box contents: brackets, grille, side panels, plugs and vent

When swapping an old radiator, measure the old pipe centres and compare them with the new one before you start. If they differ, extend or shorten the tails, or use offset valves. Hang it level, fit the valves and fill slowly. Bleed from the top, then recheck after the heating has run for a while. Valves plus other sizes are listed in our radiators and accessories category.

Common Questions

Is a 600mm Type 21 good for a hallway?

Yes. It gives decent heat and stays slimmer than a Type 22, so people brush past it less.

What should I check when replacing an old 600mm radiator?

Measure the old pipe centres and compare them with the new one before draining down.

Do I need inhibitor after fitting a new radiator?

Yes, top up the inhibitor after draining and refilling, because fresh water dilutes what was in the system.
