Urban Vertical Radiator - Anthracite - Double Panel (1800mm High) 354mm Wide

Extension radiator

11th June 2026

The product came extremely fast, it was next day, which is very rare as I live on the Isle of Wight so items generally take an extra day at least. The radiator fit exactly where I need to to fit, hangs well and is plumbed in and ready to go. Very happy, thank you.
