I hand make ceramic radiator humidifiers. You can go to www.hydronicnetwork.net and then click on cast iron radiators or you can email your address to me and I will send you a brochure. At that website you will see some of what I make. I look forward to hearing from you. There are no pans. I did a lot research and could find nothing as I also live in a 100 yr old home. So I made my own, which I now sell. Again hope to hear from you.
