I have a 32 x 52 x 9 high garage. How many BTU's do I need to heat this??
I have a kerosene forced air heater to heat my garage, it's half the size of yours and it's 125000 btu and I find it heats my garage very fast. Again my garage is very well insulated. I don't know about yours but I would go with something bigger like 200000 plus btus, if you use forced air kerosene heater.
Hope this will help you!!
