What are the most popular cast iron radiator styles?
It depends on the property and the look you're after.
For ornate period detailing, the Oxford and Piccadilly are our most decorative models: deep floral and geometric patterns that suit Victorian and Edwardian interiors. The Kensington sits in similar territory with a slightly softer profile.
For a cleaner, more versatile look, the Bartholomew and Sloane are popular across both period renovations and modern builds. Their simpler column profiles let the finish do the talking, particularly in polished or metallic options.
The Neo Georgian works well in Edwardian and Arts and Crafts properties, and is available in both 4-column and 6-column configurations. The compact Churchill fits under low bay windows, in conservatories and in loft conversions where vertical space is limited.

What types of cast iron radiators are available?
Most of our range connects to a standard central heating system: your boiler heats the water, your radiator heats the room. These work with combi boilers, system boilers and conventional setups with no special requirements beyond correct sizing and appropriate valves.
For spaces without central heating, electric cast iron radiators are a standalone alternative. They run independently from a fused spur, with a thermostatically controlled heating element and frost protection built in. Extensions, garden rooms, outbuildings and properties without pipework are the typical use case. Read our full guide to how electric cast iron radiators work.
Cast iron radiators are also well suited to heat pump systems. Air source and ground source heat pumps produce slow, low-temperature heating cycles: exactly the conditions cast iron was originally designed for. The high thermal mass and large internal water volume store heat effectively at lower flow temperatures. If you're planning a heat pump installation, get in touch and our team can advise on sizing.

How do cast iron radiators compare to steel panels?
Cast iron and steel radiators both connect to the same central heating systems, but they heat a room differently. Steel panels warm up quickly and cool down quickly. Cast iron takes longer to reach temperature but holds that heat for far longer once the boiler cycles off. This means fewer heating cycles, more consistent room temperatures and lower energy waste over the course of a day.
The material itself is denser and more resistant to internal corrosion than steel. A well-maintained cast iron radiator will outlast multiple generations of steel panels. Because they're sectional in design, individual sections can be replaced without swapping out the entire radiator: something you can't do with a welded steel panel.
Cast iron also offers a wider range of decorative options. Ornate castings, polished finishes and bespoke colour-matching aren't possible with pressed steel. If you're choosing between the two, it comes down to whether you want a utilitarian heat source or one that heats the room and adds character. Our guide to understanding different cast iron radiator styles covers the design options in detail.
Are cast iron radiators a good investment?
Cast iron radiators cost more upfront than budget steel panels, but the long-term value is significantly better. A quality cast iron radiator can last for generations: many original Victorian radiators are still in daily use over a century later. Our radiators come with a 10-year guarantee, and the reality is they'll comfortably outlast that.
Because they retain heat after the boiler switches off, cast iron radiators reduce the number of heating cycles your system runs. Over years of use, that adds up. They're also one of the few heating products that can add genuine character and value to a property, particularly in period homes and renovation projects.
Every Paladin radiator is built to order at our Lincolnshire factory, so you're buying direct from the manufacturer with full technical support, not through a chain of intermediaries. For help planning your project, see our buying guide or use our project builder to spec out multiple rooms.
How do I size a cast iron radiator for my room?
Start with your room's heat loss. Use our heat calculator to get a target BTU figure based on room dimensions, window type and insulation. Then divide that figure by the per-section output of the model you prefer.
Each of our models has a dedicated heat calculator page with full output figures at different Delta T values. Column count matters too: a 4-column radiator outputs more heat per section than a 2-column, but takes up more depth. Our buying guide covers this in detail, and our how to measure a radiator guide will help you get your wall space right. Contact us for a bespoke calculation if you'd prefer expert help.
How do I complete a cast iron radiator installation?
The right accessories make the difference between a good installation and a great one.
Start with valves. Thermostatic radiator valves give you room-by-room temperature control and help reduce energy waste.
Manual valves are a simpler option if you prefer direct control. Both are available in finishes to match your radiator. Read our radiator valves explained guide if you're unsure which to choose.
Add wall stays to secure the radiator in position, pipe sleeves to match your pipework to the valve finish, and ornate bush ends if you want to enhance the detailing at each end of the radiator. Browse the full valves and accessories range.
