Hello Permies, i need your advice! I've been working through my first RMH build. I'm hung up trying to insulate around the brick inner chimney. I read about using an electric heater's shell w/ perlite-cobb inside. When my sister got a new heater I took the old one and hack-sawed off a piece to fit the height of the chimney.
- Usable material? There are some rust-patches in an area of the panel. There is one hole that goes through, almost the diameter of a penny. I'm worried about the insulation holding vs breaking through over time.
- Access Panel hole. Due to chimney height I had to cut a piece containing the access panel for the electric heater. There is a low profile steel cover held by 2 screws that I can reattach. Again concerned about this holding the insulation in.
- Reattaching cylinder? After un-crimping where the edges come together I can't seem to get the cylinder to mate together again. Any suggestions? Should I use wire wraps and rivets to hold it in place as best I can?
- Perlite-Cobb - Is there any special clay I need to because of proximity to heat? I'm still searching forums for a good recipe
