How do I decide between a horizontal and a vertical flat panel radiator for my room?

Think about wall space and the look you want. Horizontal radiators suit traditional runs beneath windows and come in many widths, while vertical versions rise up the wall and are ideal where you have little horizontal space but need more heat. Vertical radiators often give a higher output for their footprint because they use taller heights. If you want a bold design statement, choose anthracite or black; for a subtle finish choose white.

What’s the difference between single, double and triple panel radiators in performance and projection?

Single panels have one convector fin and the shortest projection, making them good for smaller rooms. Double panels contain two parallel panels and more fins, giving higher heat output for medium to large rooms. Triple panels maximise heat output and have the largest projection, best for very cold or large spaces. our range filters show many single and double options (around 257 singles and 191 doubles), so you'll find sizes to match your room.

How do I use the BTU output listings to pick the right radiator size?

Each radiator lists a BTU output at a standard Delta 50, and our range filters group radiators into ranges from under 1,000 up to 25,000 BTUs. Work out your room's heat requirement in BTUs and then select a radiator in the matching filter band, small bathrooms often fall in the 1,000–1,999 range, while living rooms typically need 3,000–6,000 or more. Many models include heights (300–2200 mm) and widths (from about 280 mm up to 2,000 mm) so you can balance physical size with the required output.

Which finishes and colours are available and how do they affect the look of my kitchen or bathroom?

Flat panel radiators come in a wide palette: white is the most common, with popular statement colours like anthracite and black also widely available, plus brass, copper, grey and even mirror finishes. A white horizontal radiator blends discreetly into a classic kitchen, while an anthracite vertical unit becomes a contemporary focal point in a modern bathroom. Different finishes won’t materially change performance; they mainly influence style and how the radiator complements tiles, cabinets or paint.

Are flat panel radiators a practical choice for smaller rooms or tight spaces?

Yes. Flat panel radiators are made from sleek low-carbon steel and have less projection than traditional panel or column radiators, so they sit closer to the wall and save space. If you’re tight on horizontal wall area, a tall vertical model (many around 1600–1800 mm high) gives strong heat output without taking up width. For a small ensuite, a single flat panel 600 x 455 mm can provide adequate warmth while staying unobtrusive.
