Garage heat

I have a Kero-Sun 23.000 BTU Kerosene heater in my carport / work shop. A 2 car, open carport. I have it closed of with a tarp hung like a curtain. The heater keeps the space comfortable. No fumes. If you have trouble with allergies or you think you have fumes, you can burn pure mineral sprits. More expensive than Kerosene, but burns real clean. I used to sell kerosene heaters in, of all places, Miami Florida for a hardware store. "The Aladdin Blue Flame." The store owner always recommended Mineral Sprits.
