How much propane do these units over the course of a winter. I mean I want to keep my garage above freezing all winter long and crank the heat up when I'm in there lets say daily for 4 to 5 hours. 5 days a week. I live in Northern ontario is propane an option or should I go for gas.
Just wondering if you think $400 is a good price for a used unit like this with all venting and intake 20 ' long. Plus thermostat. The one I'm looking at is 80,000 BTU also is it too much for a 25 x 18 foot insulated shop with an 8' ceiling will it be dangerous...
