Hello everyone. What would be some good options to heat repair shop? The building we are looking to rent has an oil furnace but it needs a lot of work. We are starting this endeavor on the cheap and would like a reasonably inexpensive way to heat the shop for the winter? The shop is roughly 1,500 square foot on one side and then office space in the center that is walled off from the shop that would be heated with a space heater and then there is the other side that's about 1,000 square foot. There is another 1,000 square foot that I think for now we will be using for storage it is closed off from the rest of the shop. So roughly 2,000-2,500 square feet needs heated. What are some good affordable options to accomplish this? Thanks everyone.
