How do I match a DuraTherm radiator's BTU output to the size of my room?

Work out the BTU requirement for your room, then use the BTU filters (0–999, 1,000–1,999, 2,000–2,999 and so on) to find radiators that meet it. Smaller rooms and ensuites will often sit in the 1,000–1,999 band, while living rooms commonly need 3,000–4,999 BTU. If you have limited width but need a lot of heat, you’ll often find taller vertical double panels (1,800 mm high) in the higher BTU bands. Match the BTU filter to your calculation and then pick a size and panel configuration that fits your wall space.

Should I buy a single, double or triple panel radiator for my room?

Choose a single panel if you need a slim projection and modest output for a small room. A double panel gives significantly more heat for medium to large rooms while still keeping a relatively compact depth. Triple panels maximise heat output for large, draughty spaces but project further from the wall. a single-panel radiator works well in a small bedroom, while a vertical double panel at 1,800 mm suits a large hallway or living room.

When is a vertical radiator better than a horizontal one?

Go vertical if you have narrow wall space but need a strong output; there are many vertical options at 1,600–1,800 mm heights and they make efficient use of floor-to-ceiling space. Choose horizontal radiators if you want to sit them under a window or across a longer wall, common horizontal sizes include heights around 600 mm with widths from about 500 mm up to 1,440 mm. A 600 x 1,440 mm horizontal double panel is a typical choice for heating a larger lounge beneath a window.

How do profile and finish affect the look and performance?

Flat-profile panels give a sleek, contemporary look and suit minimalist kitchens and bathrooms, while oval tube profiles create a softer, more decorative appearance. Finish options such as Anthracite, Black and White let you either make a style statement or blend the radiator into the room. Performance differences are mainly determined by panel configuration and size rather than colour, so pick the profile and finish that match your decor once you’ve chosen the correct BTU and panel type.

What price should I expect and where will I see the best value?

DuraTherm radiators range from at a lower price point up to at the current product price depending on size, profile and finish. a vertical double flat panel (1,800 x 530 mm) is included in our range at at the current product price, while a vertical double at 1,800 x 455 mm in anthracite can be at a lower price point. You’ll get best value by matching the smallest radiator that meets your required BTU rather than oversizing, and by choosing a popular finish like white or anthracite if you want a good balance of cost and style.
