A popular mid-height choice, our 500mm high radiators provide an ideal balance of heat output and wall footprint. At half a metre tall, these radiators offer a slightly lower profile than the standard 600mm models, making them incredibly versatile. They fit comfortably under many standard and slightly lower windowsills, and they look great on unobstructed walls in living rooms, bedrooms, hallways, and dining areas.

We offer 500mm radiators in an extensive range of lengths, from compact 400mm widths up to 1800mm, ensuring you can find the correct size for your wall space and heating requirements. To ensure your room gets the exact heat (BTU) it needs, select from three different profiles: the slimline Type 11 (single panel), the balanced Type 21 (double panel plus), and the highly efficient Type 22 (double panel, double convector). Finished in a crisp, durable white gloss, our 500mm radiators from leading brands like Kudox Premium and Purmo are supplied complete with wall brackets, plugs, and vents for a straightforward installation.

Frequently Asked Questions | FAQs

Is a 500mm high radiator a standard size?

While 600mm is often considered the most common "standard" radiator height in the UK, 500mm is also an extremely popular and standard size. It offers a very useful middle ground. It's low enough to fit under many windowsills (where you want to position a radiator to counteract cold air), but tall enough to provide a very efficient surface area for heating average-sized rooms without taking up excessive horizontal wall space.

How do I know what size 500mm radiator I need?

To find the right radiator, you must calculate the required BTU (British Thermal Unit) output for your specific room. Once you have your BTU figure, look at the 500mm high models and find a length and "Type" (e.g., Type 11, Type 21, or Type 22) that matches or slightly exceeds that output. For example, if you have a high BTU requirement but limited wall width, you would choose a shorter but thicker Type 22 radiator. If you have plenty of wall width but prefer a radiator that sits close to the wall, a longer Type 11 radiator would be better.

What is a Type 21 radiator?

A Type 21 radiator, often called a "Double Panel Plus" or "P+" radiator, features two water-filled panels (one at the front, one at the back) but only one set of corrugated convection fins sandwiched between them. It offers a "middle ground" in terms of heat output and depth—it is thicker and outputs more heat than a single panel Type 11, but is slimmer and produces slightly less heat than a Type 22 (which has two panels and two sets of fins).
