The Clarendon is an ornate radiator valve in the high Victorian manner: a leaf-moulded body beneath a cast crown head, the kind of detail once found on the best domestic and institutional heating installations. This is the thermostatic version, with the temperature control set within the crown head so the valve keeps its period appearance. It suits our Powis, Tredegar and Nouveau ornate radiators, and plainer column radiators in rooms with rich period detail.
Each set is a pair: a thermostatic valve (TRV) for one end of the radiator, and a matching lockshield for balancing at the other. Valves are angled, for pipes rising from the floor, and fit 15mm copper pipe. Turning the head sets the room temperature up to about 30°C; turned fully clockwise, it closes but still opens below about 6°C to give frost protection.
The Clarendon thermostatic valve is not bi-directional. It must be fitted on the flow pipe, or it may be noisy in use. Please make sure your installer knows this.

Anthracite is a dark textured finish that sits naturally with black, graphite and dark heritage colours on cast iron. Brass suits warmer schemes and aged ironmongery; black nickel gives a deep polished sheen.

For a manual version, including ½” and ¾” BSP connections for older pipework, see the Clarendon manual set. You need one set per radiator. Valves carry a 5-year guarantee. Because valves are made to order, we can only accept returns if an item is faulty or damaged in transit.
The system should be flushed and dosed with inhibitor to BS 7593, and installation should be carried out by a competent heating engineer. See our cast iron radiators and the full range of traditional radiator valves, or call 0333 987 4452.

Each radiator is priced by the number of sections, from 3 to 30, so you only pay for the length you need. Prices are shown on each product page, and delivery is a flat £95 plus VAT per radiator order. Please call 0333 987 4452 or use the contact form for a quotation.
Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
Yes. Traditional cast iron column radiators are the authentic choice for period interiors, and plain patterns such as the Victorian 4 column are usually preferred by conservation officers. Replacing radiators or altering pipe runs in a listed building may need listed building consent, so speak to the conservation officer before work starts.
BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.
All of our cast iron radiators are availbale as standard with a 1/2″ BSP (15mm) connection. We are though also able to supply many of our radiators and valves with 3/4″ BSP connections. Due to the size proportions of some radiators and valves 3/4″ connections may be more suitable.
Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.
It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.
Cast iron radiators cost no more to run than modern steel or aluminium radiators. Cast iron is a very efficient material at emitting heat, thus you have items like le creuset cast iron pans. Cast iron holds it’s heat extremly well, which means that the radiators stay warm for longer.
Every product in our cast iron radiator range has a double-sided A4 technical data sheet, written for architects, specifiers and heating engineers. It includes dimensioned drawings, outputs at ΔT50 and ΔT30, weights, water content, fixing details and a model specification clause you can copy into your specification.
