How do I work out the right wattage or BTU for my room so the radiator will actually heat it properly?

Look at the wattage or BTU bands on the product, the range in our range runs from about 1,000W (roughly 3,400 BTU) up to the 6,000–7,000 BTU band and higher, and match that to the size and use of the room. As a practical guide, small bathrooms or cloakrooms often need 750–1,000W (the Towelrads Metz 429 x 610mm 750W), bedrooms and small living rooms typically suit 1,000–1,500W, and larger living rooms or conservatories usually need 2,000W or more (the K‑Rad Capri and TCP 2,000W panel examples). If a room is poorly insulated or has large glazing, pick the higher wattage within the band. Aim to heat the space you use rather than oversizing and wasting energy.

Which radiator type is best for my space, oil filled, ceramic, aluminium panel, infrared, or a glass-style heater?

Each type has clear strengths: oil‑filled radiators such as the Myson Rio Compact Plus hold heat and give gentle, long‑lasting warmth, so they're good if you want steady background heat. Ceramic or glass smart radiators warm up quickly and are slimmer, so they suit modern living rooms or bedrooms where fast response matters. Aluminium panel and 2‑in‑1 infrared/convection heaters (like the TCP 820 x 450mm 2‑in‑1) deliver quick, powerful output and can be ideal for conservatories or offices where you want immediate warmth. Choose based on how quickly you need heat, how long you'll run the unit and the look you want.

Are the smart features worth having and how will they reduce my heating bills?

Yes, smart features are worth it if you want precise control and to avoid heating empty rooms, you can use your smartphone to set 24/7 schedules and heat only the spaces you use. programme a radiator to lower overnight and raise the temperature half an hour before you wake, or have a hallway radiator off during the day and on just before you get home. Smart control reduces wasted energy by preventing unnecessary running, but you'll see the biggest savings if you use zoning and schedules consistently.

I've only got a narrow strip of wall, which radiator shapes and sizes work best for that?

Vertical radiators are exactly for narrow walls; there are many tall slim options such as the K‑Rad Capri 1600 x 362mm 1,000W or the 1600 x 544mm 2,000W models, with heights commonly at 1,600mm and 1,800mm. These give decent output while keeping the width under 400–550mm, so they suit hallways or between window and door. If you need heat under a window, a low horizontal panel (the TCP 820 x 450mm panel heaters) gives good distribution without using vertical space.

Can a smart towel radiator both heat my bathroom and dry towels effectively?

Yes, smart towel radiators are designed to do both and are offered in a range of outputs to match room size, Towelrads Metz models from 429 x 610mm at 750W up to 429 x 1,035mm at 2,000W. A 750–1,000W towel rail suits a small bathroom and will keep towels warm, while 1,500–2,000W versions are better for larger bathrooms where you want quicker drying and stronger room heating. The smart control lets you schedule towel warming only when you need it, which keeps running costs down.
