The Duchess 780mm is a tall school radiator with a simple, linear design. Neat scrolls on the feet complement the classic lines and add a subtly stylish flair. With its thick casting, the Duchess 780mm retains its heat for longer, giving a particularly well-balanced performance. A Castrads Duchess 780mm radiator heats the Dean's office in Westminster Abbey. Other school radiator styles include the Baron and the Princess.

Delivery
Delivery of cast iron radiators to Mainland UK costs £60.

Cast iron radiators are delivered lying flat on a pallet.
Our cast iron radiators are dispatched as a fully sealed single unit, ready to be plumbed into any modern central heating system. If you require an extra long radiator, it'll be delivered in two or more pieces for partial home asembly.

If you decide you don't like your radiators, you can always return them for a refund or replacement.
For exchanges, you'll jut need to pay the redelivery charge of the new radiator.

Returned Radiators2Go don't incur a restocking charge.
