So I closed on the house last Thursday. One of my first project is going to install a new roof on my detached garage, update the electric inside the garage with a 110/220 outlets, insulate, and heat it.
I am debating about wood, electric, or gas to heat the garage. I think gas would be the best route. How do I figure out how many btu gas heater I will need?
I want the heater to be a permanent installation in this detached workshop. There is also a green house attached to this building that I am also considering heating. It might be nice to consider a furnace that has two zones. I am not sure how many BTU’s I need. I am sure it is a simple formula that I have yet to find on the net. I plan to use this heater in the workshop where cars and motorcycles may be painted inside the garage. So I do not want to blow myself up.
I think gas is the best route. There are two types I am considering. Either a Hanging Garage Heater or a Garage furnace.
I found this Modine unit for sale. 100,000 btu PAE100ac hanging unit. Purchased new in 1990 for a 600 s/foot garage. Bought so big cause it was a had to go special. Only used when in garage so very little use. Also had it set up at a lower pressure so it would last forever. Setup for propane but will do gas. Works great and in excellent shape. $250.00 and i will throw in tstat and vent piping. switching over to a closet unit.
You think this is a good deal? I am not sure if it is a internal combustion unit though. I can not find any data sheet on it. This is a concern since I want to paint inside the garage and do not want to blow myself up.
Any comment or other recommendations?
