The 600mm high radiator is widely considered the industry standard height for domestic central heating in the UK. This versatile size offers an optimal surface area for effective heat convection and radiation, making it the perfect choice for heating living rooms, bedrooms, dining areas, and hallways. Because it is the most common height, you will find the largest selection of widths and profiles within this range, ensuring you can find the exact match for both your wall space and your room's BTU (British Thermal Unit) requirements.

Our extensive 600mm range includes everything from compact 400mm wide models up to expansive 2000mm options for heating very large, open-plan spaces. We stock all major panel profiles, including the slimline Type 11 (single panel), the popular Type 21 (double panel plus), the high-output Type 22 (double panel), and even ultra-high-output Type 33 (triple panel) radiators for when maximum heat is needed from a limited wall width. Choose from top trade brands like Kudox Premium, Stelrad, and Purmo, all finished in classic white and supplied with wall brackets and bleed valves ready for installation.

Frequently Asked Questions | FAQs

Is a 600mm radiator the standard size?

Yes, 600mm is generally considered the standard, most common height for panel radiators in the UK. It is a highly efficient height for convection heating and fits comfortably on most unobstructed walls in living rooms, bedrooms, and hallways. Because it is the standard, it offers the widest variety of lengths and heat outputs.

What width 600mm radiator do I need?

The required width of your 600mm radiator is dictated by the heat output (BTU) needed to keep your room warm. You should first use a BTU calculator to determine your room's requirement. Once you know the required BTU, you can look at the 600mm high models and select a combination of width and "Type" (e.g., Type 11, 21, or 22) that provides that output. A longer Type 11 will provide similar heat to a shorter Type 22, allowing you to choose based on available wall space.

What do Type 11, Type 21, Type 22, and Type 33 mean?

These "Types" indicate the internal structure and depth of the radiator, which directly affects its heat output:

Type 11 (Single Panel): One front panel and one row of convection fins. The slimmest option, ideal for hallways or small rooms.
Type 21 (Double Panel Plus): Two panels (front and back) but only one row of fins in the middle. A good middle-ground for heat output and depth.
Type 22 (Double Panel): Two panels and two rows of fins. The most popular choice for standard living rooms and bedrooms, offering high heat output.

Type 33 (Triple Panel): Three panels and three rows of fins. The deepest option, providing massive heat output—ideal for very large rooms or where wall width is severely restricted.
