Hello,very good site you all have here. Wishing now I'd have done research here, ARRRG. Had a junk tempco here when we bought the home.It's in the pole barn now. Was an alcove install. In our living room sets a beautiful Homestead soapstone stove that has a hearth req. of friggin 6.6 . Have ordered 2 sheets of mineral wool ins. board 2" thick with wire from McMaster-Carr. Dealer sold us heat shield and surround-they will not work together. Has anyone here had installs useing this board,and why does this stove loose soooo much heat out the bottem ? Will try to get pic's posted.
