I had planned to fire my small Dearborn gas wall heater (once an electric space heater) in my garage and keep repairing experimenting this winter. Unless there is an emergency, I feel I need to pass with today's fuel and energy crises vs in the 70s/80s.
I would feel OK if I could transport and use safely coals from my fireplace in the garage. Without a direct heater to exhaust the coals it's not safe in a closed garage. I have also limited my work inside "since my wife retired 06" vs building or troubleshooting combustion engines, "Just In Time". "I'm Done", for a while with Combustion Engines vs "Not Fun Troublrshooting Computers", LOL!
