Gas here also. I use a Hi-intensity infrared Dayton hanging heater. I think it is rated at 49k BTUs, the natural gas model puts out 60k. I wanted electric but none come close to the Dayton. I use a 250 gal propane tank, fill once a year @$120-140. No pilot, electronic ignition. Heats my 30x30x10 like you can't believe. Brian
