Hello, I'm Greyjoy. I wanted to let you know that one or more of your recent contributions&#32;to Solar thermal collector have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks.  Grey joy talk 14:29, 16 March 2022 (UTC)
