What size radiator do I need?


A traditional school radiator. Neat scrolls on the feet complement the classic lines and add a subtle flair. With its thick casting the Duchess retains heat for longer, giving a particularly well-balanced performance. 

Pneumatically assembled in Manchester for delivery as one piece up to 1.1m or up to 2m with partial home assembly.

All our radiators are individually pressure tested using industry-leading technology. We ensure perfect connections with your central heating system by machining all threads ourselves.  Built to last at our HQ in Manchester. Hand finished in your choice of colour and usually ready for dispatch in just seven days.

Our radiators are hand assembled so we can’t give 100% accurate pipe centre measurements before they've been made. Let us know when placing an order if your plumber is planning to lay pipes before it arrives and we’ll send you the exact measurements usually within 72 hours of an order being placed. Your plumber can then drill holes in the floor and position the pipework with absolute confidence.

Installing cast iron radiators

We supply all our radiators with 1/2” BSP connections to pair with all of our valves and most valves available elsewhere too. We can provide any valve configuration but as standard we’ll always fit them bottom opposite ends (BOE).

Our radiators are sold in over 60 finishes.
