Aluminium Vertical Radiators

Frequently Asked Questions About Aluminium Vertical Radiators

Why choose an aluminium vertical radiator over a steel one?

Aluminium vertical radiators heat up considerably faster than steel equivalents, warming a room to a comfortable temperature in a matter of minutes rather than the longer warm-up times associated with mild or stainless steel panels. They also require significantly less water content to operate, are 100% recyclable, and are naturally resistant to corrosion, making them a more energy-efficient and longer-lasting choice for any room in your home.

Are aluminium vertical radiators suitable for small rooms and narrow walls?

Yes, aluminium vertical radiators are specifically well suited to small rooms and narrow walls because their tall, slim profile makes use of wall height rather than width, delivering a strong heat output from a minimal footprint. Our slim aluminium vertical models are highlighted directly on the category page as ideal for small spaces including narrow hallways, cloakrooms, and en-suites where a standard-sized radiator would not fit.

What is the difference between a single and double aluminium vertical radiator?

A double aluminium vertical radiator such as the Tallis Double delivers a significantly higher BTU output than a single panel model at the same dimensions, making it the better choice for larger rooms, open hallways, or any space that needs more heat from a narrow wall position. Both single and double models carry the same 5-year guarantee and are available across the same colour range, so the choice is purely based on your room's heat requirement.

How do I know what size aluminium vertical radiator I need?

The correct size is determined by the BTU (British Thermal Unit) requirement of your room, calculated using its dimensions, ceiling height, glazing, insulation, and orientation. Use our BTU calculator to find the exact output your room needs and always check the radiator's rated figure at Delta T50 (ΔT50) under BS EN 442 before purchasing.

Are aluminium vertical radiators suitable for heat pump systems?

Yes, aluminium vertical radiators are one of the strongest choices for heat pump installations because they perform efficiently at the lower flow temperatures of 35°C to 55°C that heat pumps operate at, reaching operating temperature quickly without requiring the higher water temperatures of a standard gas boiler. This makes them particularly relevant for UK homeowners installing or upgrading to an air-source heat pump in 2026 and beyond.

What colours are aluminium vertical radiators available in?

Our aluminium vertical radiators are available in textured white, black, and anthracite, with all models featuring Trio paint technology and an anodised coating for a durable, easy-to-clean surface that holds up well in bathrooms, hallways, and kitchens. Colour availability varies by model, so it is worth checking the individual product page for the specific options on each radiator before purchasing.

What guarantee do aluminium vertical radiators come with?

All aluminium vertical radiators in our range carry a 5-year manufacturer guarantee and are built to a maximum working pressure of 10 bar, which is well above the typical household pressure of below 5 bar, giving you confidence in their long-term reliability. All fixtures and fittings are supplied with each model so you have everything needed for a complete installation without sourcing additional components separately.

What valves do I need for an aluminium vertical radiator?

Aluminium vertical radiators are compatible with standard thermostatic radiator valves (TRVs), which are sold separately and not included with the radiator. Browse our full range of radiator valves covering angled, straight, and corner options across a wide selection of finishes to find the right coordinating pairing for your aluminium vertical radiator.
