How do I pick the right radiator size for my room?

Start by looking at wall space and the room's layout, wide radiators (600 x 1010mm or 600 x 1460mm) suit long walls and beneath windows, while tall vertical radiators (such as 1800 x 560mm or 1600 x 380mm) work when floor space is tight. If you have a small bathroom, a compact option like 300 x 605mm gives warmth without dominating the room. Think about where pipes run and whether you need extra drying bars, then match a size that fits that wall with some clearance either side.

What's the difference between double-bar and triple-bar column radiators for performance and towel use?

Double-bar column radiators have two rows of columns and are slimmer, giving good heat for most rooms while staying less obtrusive. Triple-bar versions add a third row, increasing surface area and heat output and giving more bars to hang towels on. If you want faster drying and stronger heat in a bathroom or utility room, a triple-bar Colosseum model is practical; for a living room where looks matter as much as warmth, a double-bar can be neater.

Should I choose a vertical Colosseum radiator or a horizontal one?

Choose a vertical Colosseum radiator when you have narrow wall space or want a statement feature, a vertical 1800 x 560mm fits a hallway or narrow bathroom wall. Go horizontal when you have under‑window space or a wide wall to fill, such as 600 x 1190mm or 600 x 1460mm. Vertical models save floor length, horizontal models give a broader, more traditional heat spread.

Which colours and finishes are available and how will they change the look of my room?

The range includes classic white, bold black, and anthracite finishes, plus chrome options for valves and trims. White suits a fresh, traditional bathroom; black or anthracite creates a contemporary contrast against pale tiles or painted walls; chrome valves add a period or polished detail. a white Colosseum radiator will blend with white sanitaryware, whereas an anthracite vertical will become a modern focal point.

Are valves included and which valve type should you buy?

Valves are often sold separately and page products in our range show dedicated options like 15mm angled cross head radiator valves in chrome or black. Choose an angled valve if your pipework comes up from the floor or meets the radiator at an angle; a straight valve suits inline pipe runs. Match the valve finish to your radiator and taps for a cohesive look, chrome valves with a white radiator for a traditional bathroom.
