I have been lurking around for awhile, the posts here on this forum are very inspiring. I am thinking about converting my fireplace to a mass heater, one idea popped in my mind looks like the attached drawing.
- Basically, it means hitting the wide part of the chimney, I am not sure if the heat will be conducted to the stone surface outside the chimney in the family room.
- One of my other concerns is that I am not sure if the wide part of the chimney is lined with fire brick or normal brick.
- If it is normal brick, will the temperature be so high that it makes the brick crack?
