I own a Hearthstone 2 by Hearthstone. I love it because the soapstone retains the heat and makes it easy to start up. We've decided to use it all the time to heat our house. We did buy it used but had no problems with it last year. This year I noticed the top of the firebox sagging. I took a picture of it. I don't think we run it that hot but before we go to bed we usually do fill it with wood. Could this have been the problem? I would appreciate any advice. My husband is thinking about taking it apart this summer and banging the metal back into shape. I'm afraid we are going to have this problem every year. It also is dropping this stuff that looks like very red clay from the top now.
