Thank you for the reply delky. Yes I would be very appreciative if you could pm me a link to the article. Also thanks for the clarification about the valve. I’d looked at lots of images and couldn’t make sense of how I had a mix if items. So I’ll look up the Ranko valve and see what that’s about. I’m not worrying about the original look so much as I’d like to have a functioning heater that works in winter and doesn’t throw heat out in summer. Thanks!
