About Castrads

Castrads, established in England, manufactures custom-built, custom-finished radiators as well as controls and fittings that are suitable for both steam and hydronic heating systems. Inspired by the past but always looking to the future, their products combine classic form and enduring functionality with the most up-to-date technology.

Founded by Chris Baylis in 2006, Castrads has since been taken over by his son Nick Baylis. Nick has built upon the strong foundations laid by his father with the help of his brother, Adam.

Adam now runs UK operations while Nick develops Castrads North America in NYC. Beyond the family, Castrads has been built by a team of highly talented and committed individuals, many of whom have been with them for over ten years. They’re passionate about what they do, and they do it well.
