Built from premium steel with a crisp white powder-coated finish, this wall-mounted vertical radiator delivers powerful, efficient heat while making a bold architectural statement.

Why the Kartell Aspen Vertical Radiator?

Vertical radiators are the smart choice when floor space is tight and wall height is your best asset. The Aspen's slim, tall profile fits neatly into hallways, bathrooms, living rooms, and bedrooms, freeing up valuable wall width without compromising on warmth.

• Single Panel — ideal for smaller rooms or supplementary heating
• Double Panel — higher BTU output for larger spaces or primary heating
• Pipe centres at 420mm for straightforward installation on standard UK central heating systems
• Depth of just 55mm — sits close to the wall for a clean, unobtrusive look
• Compatible with all standard central heating systems (no specialist plumbing required)

Key Features

• Premium steel construction — durable, corrosion-resistant, and built to last
• White powder-coated finish — easy to clean, resistant to chips and stains
