This allows airflow to be regulated without removing or replacing the grille. The vent can be fully open, partially open, or fully closed depending on ventilation requirements.

BS 460:2002 is the British Standard governing cast iron rainwater goods — gutters, pipes, and fittings. It sets the dimensional tolerances, materials, and performance requirements a component must meet, so that joints seal, sections align, and the system performs as a whole rather than as isolated parts. All Tuscan Foundry Products components are manufactured to comply with BS 460:2002, which is worth citing directly in specification documents and listed building consent applications. The same manufacturing standard applies to bespoke and copy-cast work, even where the profile itself isn't from our standard range.

Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.

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.

Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.

The Pultney Tapered Hopper Head is well suited to Georgian and Regency townhouses, Victorian terraces, rural farmhouses, barns, and functional estate buildings where a plain, period-correct hopper is the appropriate specification. It also works well on new heritage-style construction. Its unfussy, chamfered form makes it a versatile choice across a wide range of traditional building types.
