Cast Iron Radiators

Choosing a cast iron radiator comes with a few extra things to think about, from how the material heats to weight, sizing and installation. These FAQs cover the key points to help you choose the right radiator for your room and heating setup.

 

What are the benefits of cast iron radiators?

Cast iron radiators warm up more slowly than many steel models, but they also hold onto heat for longer once the heating switches off. Their sectional, column-style construction gives them a distinctive traditional look, while the range includes different sizes, finishes and heat outputs. Just bear in mind that cast iron is much heavier than steel, so installation and floor loading need more consideration.

 

Are cast iron radiators efficient?

Cast iron holds onto heat for longer than many steel radiators, but that doesn’t automatically make it more energy efficient or cheaper to run. It takes longer to warm up and cools down more slowly, so it can suit rooms where you want steady warmth over longer periods. How much energy you use depends on how powerful the radiator is, how you heat the room, how quickly the room loses heat and how you control the heating.

 

Do cast iron radiators need extra support?

Cast iron radiators are considerably heavier than standard steel radiators, especially as you add more sections. The models in our range are floorstanding, so check the radiator's stated weight and make sure the floor beneath it is suitable before installation. Larger models can also be difficult to move once assembled, so follow the manufacturer's handling and fixing instructions and get professional advice if you're unsure about the floor or installation.

 

Can cast iron radiators work with modern central heating?

Yes, many cast iron radiators are designed to work with modern central heating systems. The important thing is to check the radiator's connection size, required valves, heat output and any manufacturer guidance for your system. If you're replacing an existing radiator, the pipework may also need adjusting because cast iron models can differ in width, depth and connection position.

 

Can I get electric or dual fuel cast iron radiators?

You can. Electric cast iron radiators and dual fuel versions are handy for rooms without central heating, such as loft conversions or garden offices. Dual fuel gives you flexibility; central heating in winter, electric warmth when you just need a quick boost.

 

How do I care for a cast iron radiator?

Keep dust from building up between the columns and around the sections, where it can be harder to reach than on a flat panel radiator. For central heating models, bleed the radiator if trapped air is causing the top to stay cold. If the finish ever needs touching up, make sure you use a paint that's suitable for radiators. A little care now and again keeps your Victorian radiators looking smart and working efficiently for years.
