- Need to use outside air since the shop is very tightly sealed. R19 walls, R50+ in ceiling
- Shop is 24x27x10ft ceiling
- Does not need to be fancy looking, just functional
- Exhaust could be preferably vented out the side
I have a keystoker with coal-Trol for the house, so I wanted to use the rice coal also in the shop. I am using a 220V garage heater in the shop; set for about 50-53F. The mrs is alarmed at the last elec bill of $100 more in a month.
