Cast Iron Radiators

Shop cast iron column radiators - authentic period style with the substantial heat retention cast iron is known for.

Cast iron column radiators bring genuine heritage character to a room, and their dense material holds warmth long after the heating goes off. They suit period homes, renovations and any space where you want a traditional radiator that's as much a feature as it is a heat source.

Cast iron vs cast iron style

There are two routes to this look. True cast iron radiators are made from the metal itself - heavy, slow to warm and slow to cool, giving a gentle, lasting heat. Cast iron style radiators recreate the traditional column appearance in steel, so they're lighter, easier to fit and quicker to respond, while keeping the classic look. If you're after the authentic weight and heat character, choose from the true cast iron range; if you want the style with easier installation, the steel column versions deliver it.

How to choose a cast iron column radiator

Three things get you to the right radiator - size, column depth and finish.

• By size - use our BTU calculator to match the output to your room, as cast iron's slow, steady heat suits rooms in near-constant use.
• By column depth - more columns and rows mean more surface area and more heat from the same width, useful where wall space is tight.
• By finish - from classic full-polish ornate styles and highlight finishes to painted period colours, pick what suits the room's era and scheme.

Sizing and output

Cast iron takes longer to heat up and longer to cool down than steel, so it suits steady background warmth rather than quick bursts. Size it generously to its room with the BTU calculator, and pair it with the right valves for the control you need.

Frequently asked cast iron radiator questions

Do cast iron radiators take longer to heat up?

Yes - cast iron's density means it warms more slowly than steel, but it also holds heat for longer after the heating switches off, giving steady, even warmth. That makes it well suited to rooms in regular use.

What's the difference between cast iron and cast iron style?

True cast iron radiators are made from the metal, so they're heavy and hold heat well. Cast iron style radiators recreate the traditional column look in steel - lighter, easier to install and quicker to warm up. Both give the classic appearance.
