I'm looking for a basic, occasional use heater for my garage. The garage is
single car, 410 square feet, uninsulated. Use of the heater for short term
emergency (power outage) indoor heating would be a plus.

What are people's experiences with kerosene vs propane for cost,
effectiveness, safety, cost, etc.? What BTU rating has worked well for
people in similar situations?

Thanks in advance.
