You mean Propane? I thought about it, but it doesn't pan out dollar wise. Propane is 2.29-2.49 a gallon here, plus the tank. And they would need to come refill it. Electric is gonna be our best bet.
Here in MO our LP supplier offers a pre buy program.
I purchased all the LP for my my house and my 40X50 foot shop back in August 18 for $1.15 a gallon.
If you do it right you cant bet Nat gas or LP for heat, electric dont even come close cost$ wise.
