My head is starting to spin looking at all the options. LOL 
I have a 28 X 26 garage. One bay has a loft floor at about 7' and the other side is a gable roof that goes about 14' at it's highest. (built that way to install a lift this spring)
I'm only interested in heating this when I'm in there which would be about 7-8 days out a month??? Average winter temps are 20-35 degrees here in Pa.
I am fairly certain that I want to go with propane and buy my own 100# cylinder that I will take to get refilled when needed. That way, I don't pay extra for delivery, etc. I called a place today and estimate it would cost about $71 to fill it at todays price. ($3.11 per gallon)
Now, what size and type of heater do I go with?
I have found a portable 30-55,000 BTU Mr. heater for $119, portable 75-125,000 BTU Mr. heater for $169, a wall mounted Big Max 45,000 BTU for $389 or a Big Maxx 75,000 BTU for $449. Or is there something better than these?
What are the pro's and con's of using the portable units compared to the wall mounted type? I see a big difference in price but I'm sure there is more to it than that...
Will the wall units run ok on a 100# cylinder or do they consume more fuel?
Appreciate any tips or leads on the best set up.
Thanks,
Bob
