Regarding the use of propane shop heaters. When we lived in Oregon I bought one of those "orange torpedo" type heaters with electronic spark ignition and used it with a standard barbeque grill type propane tank. I seem to recall it being 75,000 btu/hr.A standard gas grill type propane tank is nominal 20 lbs. or 4 gal. of propane, which has a heating value of about 71,000 btu/hr/gal. As you can see, with a 75,000 btu/hr heater you have a little less than 4 hours of blowing and going at full blast. I used to use it to warm the garage up (15 min. or so), then fire it up again every hour or as needed to take the chill off. Sucker was too loud to run continuously in there even if I had wanted to, but it sure was warm when the heater was running. I never worried about CO or CO2 because my garage door had cracks that you could drive a VW through, all around it, and I never ran the heater unattended or for extended periods.And hey, Jim Markle- what line of work are you in? If you're in science or engineering or anything related (chemistry, geology, etc.)- we are always looking for engineers, scientists, and technicians at Southwest Research.
