Look at how much heat you need and how much wall depth you can spare. Single panel single convector models (Type 11 / K1) are the slimmest and suit small bedrooms or halls, while double panel double convector (Type 22 / K2) gives noticeably more output for living rooms. Triple panel triple convector (Type 33) delivers the highest output if you have a short wall but need lots of heat. a compact 450 x 600mm Type 11 is ideal for a small bedroom, whereas a 600 x 1600mm Type 22 will warm a larger living area more effectively.

How do I match a Stelrad Compact radiator to the BTU requirement of my room?

Use the BTU Output (Delta 50) products in our range to match the radiator's stated output to the heat loss calculation for your room. The catalogue groups outputs from 1,000 up to 25,000 BTU, so you can filter for the exact range you need and then pick a size that fits your wall, radiators in the 4,000-6,000 BTU range are commonly available in 600 x 900 or 600 x 1200mm sizes. If you need a quick steer, smaller bedrooms often fall in the 1,000-2,000 BTU band, while medium living rooms typically need 3,000-6,000 BTU. Match the BTU figure first, then confirm the physical width and height will fit the space.

What practical difference does Stelrad's steel construction and powder-coated finish make?

High-quality steel gives reliable heat transfer and structural strength, while the robust powder-coated finish resists wear and corrosion so the radiator stays looking good over time. That low-maintenance surface makes cleaning easy and is reassuring for humid rooms such as kitchens or bathrooms. The catalogue emphasises longevity and energy efficiency, so you get durable performance as well as a neat painted appearance.

When would I pick a vertical radiator over a horizontal one?

Vertical radiators are useful when wall width is limited but you have height to spare, such as between a door and a window or in narrow hallways. The range includes vertical options and heights up to 2,000mm, and widths can be as narrow as 300mm, so you can get significant output without a wide footprint. a 300 x 1500mm double panel radiator gives good heat in a tall, narrow space where a traditional horizontal model would not fit.

How do I balance a sleek look with maximum heating performance?

Sleeker models like single panel types or the "Compact with Style" variants keep a slim profile and suit modern interiors, but if you need higher output you'll move to double or triple panels which are deeper. The Compact range is designed to be slim yet efficient, so you can often meet your heat needs with a compact-looking double panel Type 22 rather than a bulky alternative. If you want minimal projection into the room, opt for a higher-performance double panel in a taller or wider size rather than a triple panel that sticks out more.
