Stelrad Vertical Radiators

Match the radiator's BTU output to the heat loss of your room and then pick a height/width that fits the available wall. Stelrad verticals come in heights from 1600-2200 mm and widths of 400-700 mm, so a tall 2200 x 400 mm unit suits a narrow hallway with high ceilings, while a 1800 x 600 mm model gives more surface area for a medium living room. Use the product BTU bands in our range, 5000-5999 BTU is typical for small ensuites, 7000-8999 BTU for average living spaces, and 10000+ BTU for large or open-plan rooms. If you're unsure, aim to match the radiator's included in our range BTU to a conservative estimate of your room's required output.

A Double Panel Double Convector (often shown as Type 22) has two panels and two convector fins between them, so it delivers significantly more heat for the same face area than a single convector version. The Double Convector units included in our range here are ideal when you have a slim width but need high output, a 1800 x 400 mm Type 22 in a cold bathroom. A Single Convector will be slightly slimmer in performance and can be fine where heat demand is lower or you have space for a wider radiator. In short: convectors boost output; more convector surface equals more heat.

Yes, provided the vertical radiator's BTU rating matches the horizontal radiator you're removing. Stelrad verticals are available in high outputs, some models reach 7000-9000 BTU and above, so you can get equal or better warmth while freeing up low-level wall space. Bear in mind the look and heat distribution differ: a tall slim unit draws heat higher in the room and creates a modern focal point. If you want even heat across a wide wall, choose a taller unit with a larger width (1800 x 600 mm or 2000 x 600 mm).

For narrow areas you'll appreciate the slimmer widths (400-500 mm) paired with taller heights (1800-2200 mm), which provide strong output without taking horizontal wall space. a 2200 x 400 mm Planar K2 gives good heat output in a long corridor, while a 1600 x 600 mm Compact K2 is a good compromise for a narrower bathroom that still needs warmth. Look for the double panel double convector options if the space is small but the room is cold, because they maximise heat from a small footprint.

Yes. These panel-style radiators are designed for efficiency and low upkeep; double panel convector constructions give high output so you can run at lower water temperatures when paired with modern boilers or heat pumps. The Planar and Compact K2 ranges combine durable construction with simple surfaces that wipe clean and require little maintenance. That means you get strong, reliable heat and a neat appearance with minimal fuss.
