Narrow Duchess Cast Iron Radiator 460mm
Classic Victorian Radiator – Slim Profile & Authentic Design

The 460mm (18 inch) high Narrow Duchess Cast Iron Radiator is the smallest size in this slender, historic range. Slightly slimmer than the Traditional Duchess model, this Victorian classic is ideal for hallways and narrow rooms where space is limited.

Believed to have originally been manufactured by the American Radiator Company circa 1890, the Narrow Duchess model is a faithful reproduction that combines authentic period style with practical modern heating performance.

Available in a range of classic and contemporary finishes, this radiator fits beautifully in period properties as well as contemporary apartments.

Once your order is placed, you’ll receive an email confirmation and a provisional completion date.
Painted and powder-coated radiators typically have a lead time of 10–20 working days, depending on workload.
Metallic and polished finishes may take a little longer due to the detailed hand-finishing process.
