OK, this pertains to 62-65 in an oblique way. What are you folks in the colder winter climates doing for shop heat?? I have decided I must do something or I will get nothing done this winter. I rent the shop so hard piping gas in is out of the question. There are clean burn propane units I know which can be used indoors. There is electricity. The shop has a 220 outlet but it is the standard type, not the heavy duty industrial 3 phase( or whatever its called ). I have found several 5000/7500 watt units for pretty reasonable prices. I also found a 10000 watt unit .
My area is 25 x 34 with a 12 foot ceiling. It is insulated, but sits on a slab.
