Welcome to the shit show.
1200 sq ft garage. What hanging natural gas heater should I go with? Walls ceiling and garage doors are insulated.
Electric heaters have the same issues with flammable gas.Why not 220V instead? No flash fire concern with flammable gas vapor and no vent needed.
Not sure how big the one my shop has but it will run you out of the 700 sqft first floor now that all the walls and the ceiling are insulated.
