Sustainable Heating, Built to Last
Specializing in bespoke cast iron radiators built to order in the UK, plus a curated collection of century-old reclaimed radiators, Castrads offers heating solutions with the longest lifespans and lowest carbon footprints.
Designed for Tomorrow's Heating
Cast iron's exceptional thermal mass makes it ideal for low-temperature heat pump systems, holding heat longer and reducing energy cycling. Every radiator is precisely sized to eliminate waste and maximize efficiency - whether you choose our bespoke collection or a beautifully restored vintage piece.
Circularity In Action
We practice what we preach: our London showroom runs on an air-source heat pump, our production facility recycles waste heat and water, and we only work with lower-impact electric foundries. Through integrations with sustainable heating platforms like Spruce and H2X, we make specifying low-carbon heating systems effortless for architects and heating engineers.
