How do I match a radiator's size and BTU output to the room I need to heat?

Look for the BTU output band that matches the room's size and heat loss, our range lists bands from 0–999 up to 8,000–8,999 BTU (Delta 50), so you can choose a radiator with the stated output rather than guessing. Pay attention to the physical sizes available too: common heights are 600mm and 1800mm, and widths range from about 200mm up to 2,000mm, so you can find a shape that fits your wall. a medium room often needs a radiator in the 2,000–3,999 BTU range, which you'll often find as double-panel models around 1000–1400mm wide. If you're unsure, pick a model with a higher BTU within the list of available sizes to ensure comfort.

What are the practical differences between aluminium, mild steel and steel radiators?

Aluminium radiators heat up quickly and are lightweight, which suits contemporary designer verticals such as the Solaro Guardia aluminium ranges; they're good if you want fast response. Mild steel is the most common option here and gives a balance of cost, durability and a traditional look, ideal for column or classic profiles. Steel (often used for flat panels) is robust and holds heat well, making it a solid choice for large, daily-heated rooms. In short, pick aluminium for quick heat and modern styling, mild steel for value and traditional looks, and steel for durable flat-panel heating.

Should I choose a vertical or horizontal radiator for my room?

Vertical radiators are perfect when wall width is limited but you have floor-to-ceiling space; the range shows many vertical options such as 1800 x 600mm models in designer and column styles. Horizontal radiators work best under windows or where you want a low-profile look; there are many horizontal sizes like 600 x 1200mm for that purpose. If you have a narrow hallway or a small bathroom, a tall vertical, such as an 1800mm high double panel, will save wall space and still give strong output.

What does single, double or triple panel mean for heat output and depth?

The panel configuration indicates how many flat panels and convector fins the radiator has: single panels have the shallowest projection and suit smaller rooms, doubles give more output for medium rooms, and triples (or 6-panel) provide the highest heat for large spaces. Expect single panels to sit neater in shallow alcoves, while double or triple panels project further from the wall but deliver substantially more BTUs. a double flat panel 1600 x 455mm will produce noticeably more heat than a single of the same footprint, making it a good choice for a living room where space allows.

Can I get electric or multifunction radiators, like mirror or towel versions, in this range?

Yes, the range includes electric radiators such as the K-Rad Capri in 1000W and 2000W options, which are useful if you don't have central heating or want a standalone heater. You'll also find mirror radiators that combine reflective surfaces with heating, and specific towel radiator styles for bathrooms. Choose an electric 2000W unit for larger rooms, a 1000W for smaller spaces, or a mirror/towel model when you want a practical two-in-one solution that saves space.
