I am looking for everyones opinion on a small garage heater. I have about $200 to spend. The garage is a one stall. I don't has gas or propane in my house. How ever a propane bottle would work. I was thinking torpedo heater. How noisy are they? Also, how about fumes? I was going to try a wood stove but it would have been a few hundred in stove pipe. I am not looking for something to get the temp to 70 deg. but warm enough to work in sweatshirt. Thanks in advance!
