What is a flat panel radiator?

A flat panel radiator is a type of convector radiator with a smooth front surface or smooth vertical columns and slimline profile. The clean, linear design gives a modern appearance while maintaining excellent performance. Whether you’re renovating a living room, bedroom or hallway, a flat panel radiator delivers comfort without compromising on aesthetics.

For vertical versions, visit our flat panel central heating radiators page to explore compact and tall flat styles for tight wall spaces.

Stylish and space-saving

Flat panel radiators are ideal for modern homes looking to maximise usable wall space. Their minimal depth makes them a popular choice in busy areas or smaller rooms where a bulkier column radiator might be less practical. Choose from single, double, and even triple panel models depending on the BTU requirements for your space.
