TC Joy radiator virtual exhibit

I would like to invite those interested in TC Joy company radiators to view and share the new virtual exhibit giving company, family, and technical information. The exhibit was created by the Titusville, PA Historical Society and graduate students in the MSLS-archival concentration program at Clarion University of PA (now PennWest). It is intended for the general public, so the "how radiators work" info is very general, but we do invite any additional info or insights you might have. You can email those to the email at the site. Enjoy! https://titusvillepaheritageconnection.omeka.net/exhibits/show/tcjoy/joyintro

    Thank you, Rhonda. It's wonderful to see history come alive like this!

    I noticed that the website says that the TC Joy radiators were used for steam heat. They were also successfully used for hot water heat as well. The ones that I found out West here were all on hot water systems.

    Thank you, Alan, for the comment! I'll make sure that is more clear. I love the steam ones, so that probably came through! Unfortunately, mine are starting to fail. I have lost one beautiful rad that was under a window and hard to locate at only 12" high and one TC Joy one went this winter. I think the system is getting a lot of oxygen introduced. These were installed 1895 here in Titusville where Joy lived. Need a new boiler and my rads are not good candidates for hot water conversion. Lots of decisions looming. Maybe I'll post on another thread to get some ideas!

    @big_giant_house , why would you want to convert to hot-water?
