My wife heats her shop (quilting shop) with an unvented heater and keeps it turned low when not in it. She burns about one tank (300 gallons) per heating season. She keeps a lot of her plants in the shop so they wont freeze. We put a CO2 monitor in the shop but it has never registered a problem with the CO2 levels. The heater is the ceramic type that is wall mounted and has a thermostat. I was impressed with her results so I put one in my shop.
How big is her shop? Insulated?
