Flat Panel Radiators – Designer Horizontal & Vertical Radiator
Couldn't load pickup availability
Flat panel radiators with a smooth, contemporary front face in single and double configurations. Available in anthracite grey, white and black across a wide range of horizontal and vertical sizes. Behind the flat face are convector fins that maximise heat output without adding visual bulk.
Used in living rooms, bedrooms, kitchens, bathrooms, offices and hallways. The flat front hides dust and is easy to clean — a practical choice for busy households, rental properties and commercial spaces.
Single Panel vs Double Panel
Single-panel radiators have one panel and one set of convector fins — slimmer projection from the wall, lighter weight and suited to smaller rooms or secondary heating. Double-panel radiators have two panels and two sets of fins, delivering significantly higher BTU output in the same face dimensions — suited to larger rooms and areas with higher heat demand.

Frequently Asked Questions
What is a flat panel radiator?
A flat panel radiator has a smooth, flat front face with no visible columns or fins, giving a clean contemporary look. Behind the flat panel are convector fins that maximise heat output. Available in single-panel and double-panel configurations, with double panels giving roughly twice the BTU output for the same face dimensions.
What is the difference between single and double flat panel radiators?
A single flat panel radiator has one panel and one set of convector fins — slimmer, lighter and suited to smaller rooms. A double panel has two panels and two sets of fins, delivering significantly higher heat output in the same footprint — suited to larger rooms and areas with higher heat demand.
Can flat panel radiators be mounted horizontally and vertically?
Yes. Our flat panel radiators are available in both horizontal and vertical formats. Horizontal models sit under windows or along standard walls. Vertical models are tall and narrow, saving wall space in hallways, kitchens and compact rooms.
What colours are flat panel radiators available in?
Our flat panel radiators are stocked in anthracite grey, white and black finishes across all sizes and formats.
Are flat panel radiators compatible with UK central heating?
