How do I pick the right size and heat output for my room?

Measure the room and compare your heat-loss estimate to the BTU output filters shown here — options range from about 1,000 up to 25,000 BTU (Delta 50) so you can match the radiator to the room's needs. Double panel radiators give more heat than single panels, so for a medium or larger living room you'd typically choose a Type 22 double panel (commonly available in sizes such as 600 x 1200mm or 600 x 1600mm). If your calculation shows a mid-range output requirement, a K‑Rad or Stelrad Type 22 in a 600mm height and 1200–1600mm width will often be suitable. If you're unsure, use the BTU output filter to narrow options that meet your calculated requirement.

What's the practical difference between single, double and triple panel radiators?

Single panels have one convector fin and the shallowest projection, so they suit small rooms or tight spaces. Double panels (Type 22) have two panels and usually one or two convector fins, delivering significantly more heat and working well in medium to large rooms. Triple panels have three panels with multiple fins and the largest projection, so you'd use them where you need maximum output, for example in a large open-plan area with high heat loss.

Will a double panel radiator protrude too far from the wall or make my room feel cramped?

Double panel radiators do project more than single panels because of the extra panel and convector fins, so they can sit further into the room. If you have a shallow window recess or limited clearance, consider a horizontal unit with a narrower depth or a vertical orientation — there are vertical double panel options listed as well. For a slim window bay you might select a 300–400mm wide model, whereas a broad wall can take a 600–750mm width without feeling overwhelming.

Which finishes and panel profiles give the best look for modern or traditional rooms?

Flat panel profiles dominate the range (many models are flat), delivering a clean, modern look, while other profiles provide more texture for a classic feel. Colours include white, anthracite and black, so you can match neutral white radiators to a minimalist scheme or choose anthracite/black for contrast against pale walls. Side and top panels conceal the convectors for a neat, traditional appearance if you prefer a tidier, less industrial look.

Are there meaningful differences between materials and brands I should know about?

The collection mainly features steel and mild steel radiators, both widely used and durable; steel tends to be very robust and mild steel options are common where cost and practicality matter. Stelrad, K‑Rad and Solaro are prominent brands here, each offering a wide range of sizes and Type 22 double panel models — for example Stelrad's Planar and K‑Rad's Kompact ranges appear in multiple heights and widths. Pick a reputable brand if you want a broader choice of standard sizes (600 x 1200mm, 600 x 1600mm, 500 x 1400mm and similar) and consistent performance.
