  • Propane is more expensive to run, but you can find it in portable tanks readily available at hardware stores.
  • Kerosene is a less common option but can be more convenient to use since it can be stored easily.


A thermostat is a device that controls the temperature setting of a gas space heater. It can help you maintain an ideal temperature level in your garage and save you money in the long run. Remember the following:
