Bartholomew Cast Iron Radiator

Ever wondered where the simplest, most functional radiator designs actually came from? The Bartholomew traces its roots back to hospital wards, not grand drawing rooms. It’s a design built for reliability first, and that’s exactly why it still works so well today.

We cast every Bartholomew at our dedicated foundry and hand assemble it at our factory in Lincolnshire. The process hasn’t changed much since the original, and that’s rather the point.

A Victorian Hospital Design

The Bartholomew takes its name from a well known London hospital, where this style of radiator was used to heat wards during the Victorian era. It wasn’t designed to impress. It was designed to work, day in and day out, in some of the busiest buildings in the country.

That no nonsense approach is what gives Bartholomew its character now. There’s no fussy detailing to clean or maintain, just clean lines and a shape that suits almost any room. So whether you’re restoring a period property or fitting a radiator into a newer home with a more traditional look, it tends to sit well either way.

Available Heights

Two heights are available, so you can match the radiator to your room and your windowsills.

570mm: Fits comfortably under most standard windowsills. A good option for bedrooms, bathrooms and smaller reception rooms.

740mm: A taller radiator with more surface area, which means more heat output for larger rooms or spaces with higher ceilings.

Available Column Configurations

Built up section by section, the Bartholomew can be sized to fit almost any space you have in mind, from a compact 3 section model to an extended 40 section run. Even longer sizes are available on request.

Compact, 3 to 10 sections: Lengths from 249mm to 749mm. Good for bathrooms, hallways and smaller rooms where floor space is tight, without giving up on heat output.

Mid range, 11 to 25 sections: Lengths from 821mm to 1,822mm. The range most people choose for living rooms and bedrooms, striking a decent balance between presence and practical output.

Extended, 26 to 40 sections: Lengths from 1,893mm up to 2,894mm. Suited to larger rooms, open plan spaces or anywhere you’d rather run one long radiator instead of two smaller ones. At 740mm and 40 sections, output reaches as high as 19,241 BTUs (5,639W). Even longer sizes are available on request.

Add a section and you add both length and heat output in a predictable step, so it’s straightforward to work out what you need using our heat calculator figures (Dt50 and Dt60 outputs in BTUs and Watts).

Electric Bartholomew Radiators

Not connected to central heating? Ask us about the electric version. It carries the same hospital inspired styling but runs independently, without any need for pipework.

An electric cast iron radiator suits:

• Period properties without gas central heating
• Extensions and conversions where running pipework isn’t practical
• Listed buildings where system changes are restricted
• Conservatories and garden rooms
