Radiator Valve Sizes

Radiator valves come in various sizes, with the most common being 15mm (standard). The size refers to the diameter of the valve, and it's crucial to choose the appropriate size to match the pipework in your heating system. Larger valves, such as 22mm, are typically used in high-capacity older systems, while smaller sizes like 10mm and 8mm microbire are often used in specific, space-constrained retrofit installations.
