I haven't decided whether to go with electric, propane or fuel oil. I would like to know how to determine how many BTU's would be required with each of these types of furnaces. Jeff from Glyndon, Minnesota A - I will answer your question about the fuel choices, but the BTU calculation will depend upon more than just the sq. For example, ceiling height, insulation, usage and type of furnace and heat distribution system. A well insulated car mechanics hobby shop with 8 ft.
Electric heat takes longer to heat and in most places is the most expensive fuel source.
It might be a good choice if you only use the shop a few hours per week. OIL HEAT - Higher installation costs, relatively fast heat delivery. In light of the problems with underground tanks, I would go with an above ground tank. Please see Underground Oil Tanks . Most units can be converted to natural gas, if that becomes available.
