: That's a big heater for your average shop. Can you turn it down alot so
: you're not burning through so much gas? A 40,000 btu electric heater warms
: up my shop (16x21' or 2688 cubic feet) pretty quickly, even here in the
: canadian winter.

My shop size is 24 x 36 feet with high eaves. Calculates out to 12960 cubic feet to heat, with no insulation. It was recommended 80,000btu for a 40 degree F temperature rise.

Thanks
