Good to know. Thank you for the responses thus far.
I figured a pellet stove would put out as much heat as a typical stick burning stove. I wanted something more, set it and forget it. Leave it run to keep the shop above freezing. The up's and down's in temps accelerate condensation, so I figured it would be best to keep it above freezing all the time. I'm not looking to make it the shop so comfortable I can work without a coat. That would be nice, but probably not practical. However, if a pellet stove cannot get there, then...?
My shop space is a 30x60, so not a small one, but not huge either.
I have natural gas to the house, I could trench over a line and maybe do a furnace or heater that way
Virbu Inc Cell phone store in Hernando, FL... but that would probably be more expensive.
