I'm in western Iowa and need a heater to run in the garage maybe 10 hours a week tops. The garage is over 70 years old and not tightly sealed at all. I'm about to pull the trigger (within the hour) on a Dewalt DXH45LP. I have not seen much info on this heater does anyone here have any experience with this? I plan tonrun it off of 100 or 40lbs cylinders just outside the door. I was going to buybit weeks ago and just noticed its even lower in price today.
