The Victorian 4 column is the classic British cast iron radiator: square-edged columns, a plain face and a profile true to radiators fitted in houses, schools and institutions from the 1880s onwards. At 935mm high it suits pier walls, landings and stair walls with no window sill to clear, giving the most output per section in the range. It is supplied in primer, ready to be painted on site, so the decorator can match the room’s joinery or a historic colour scheme in the same paint system. Primer is the usual choice on conservation projects, and lead time is typically 14 days.

Each section is 55mm wide and 140mm deep, and gives 116.4W at ΔT50 (tested to BS EN 442). On a heat pump at ΔT30 that falls to about 59.9W per section, so size the radiator at the temperature your system will actually run at. Radiators are rated to 6 bar working pressure, have ½” BSP connections and carry a 10-year guarantee.

Sizes at a glance

Sections	Length	Output ΔT50	Output ΔT30	Price ex VAT
6	354mm	698W	360W	£490.20
10	574mm	1,164W	599W	£817.00
14	794mm	1,630W	839W	£1,143.80
20	1,124mm	2,328W	1,199W	£1,634.00

Length is the number of sections × 55mm + 24mm. Sections are sand cast, so allow ±2mm per section and set valve tails once the radiator has arrived. Valves are sold separately: our Kentwell, Belgrave and Clarendon valve sets suit this radiator.

Choosing and sizing

The 935mm height is usually chosen for landings, stair walls and high-ceilinged rooms where wall height is available. To size it, divide the room’s heat loss by the output per section and round up. Our guide to sizing cast iron radiators for a period room and our guide to cast iron radiators with heat pumps work through examples, and the 2026 specification guide (PDF) lists every height and output. The same radiator is also available factory painted. See the whole Victorian radiator range or the radiators in period rooms in our radiator gallery.

The Victorian 4 column is the plain pattern conservation officers usually prefer in listed buildings. Send us your room heat losses and we will prepare a radiator schedule with section counts and lengths at boiler and heat pump temperatures. Call 0333 987 4452 or contact us.

FAQ Categories

What is the output of the 935mm Victorian 4 column cast iron radiator?

Each section gives 116.4W at ΔT50, tested to BS EN 442. At heat pump temperatures of ΔT30 that falls to about 59.9W per section, so a 10-section radiator gives 1164W at ΔT50 or about 599W at ΔT30.

How long is a 935mm Victorian 4 column radiator?

Length is the number of sections multiplied by 55mm, plus 24mm for the end bushes. A 10-section radiator is 574mm long and a 20-section radiator 1124mm. Allow ±2mm per section for casting tolerance.

Is a Victorian 4 column cast iron radiator suitable for a listed building?

Yes. The plain four-column pattern is true to radiators fitted from the late nineteenth century and is the pattern conservation officers usually prefer. Replacing radiators or altering pipe runs in a listed building may need listed building consent, so check with the conservation officer early.

Can I use the 935mm Victorian 4 column radiator with a heat pump?

Yes, if it is sized for the lower water temperature. At ΔT30 each section gives about half its ΔT50 output, so you will usually need more sections than on a boiler. We can prepare a radiator schedule at your heat pump's design temperature.

How much does a 935mm Victorian 4 column radiator cost?

The primed radiator is priced per section at £81.70 ex VAT, so a 3-section radiator is £245.10 and a 20-section radiator £1,634.00. Delivery is a flat £95 plus VAT per radiator order. Please call 0333 987 4452 or use the contact form for a quotation.
