What pipe connection sizes do your cast iron hopper heads accept?

What pipe connection sizes do your cast iron hopper heads accept?

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.

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

Yes. Cast iron hopper heads are the historically appropriate choice for listed buildings, and are generally preferred by conservation officers and local planning authorities over modern plastic alternatives. Tuscan Foundry cast iron hopper heads are manufactured in solid grey iron and are suitable for use on listed buildings and within conservation areas. A linseed oil finish is also available, which is particularly appropriate for sensitive heritage projects.

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

The Antique Black finish is cast iron with a blackened surface — the most historically accurate finish for cast iron ironwork and the most appropriate for the majority of heritage applications. Polished Lacquered is cast iron with a bright polished surface sealed with clear lacquer, suited to interiors and sheltered locations where polished ironwork is the specification. Polished Brass is solid polished brass throughout — the correct choice where existing building fittings are in brass or where a warm metal tone is required.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

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.

Polished chrome has a bright mirror finish, while satin chrome has a brushed, low-sheen appearance. Both are available in the telescopic hand winder range. The finish choice typically depends on the ironmongery specification for the project.
