Just picked up a Mr. Heater Hero 60 to heat my 28x30 fully insulated garage. I have an electric heater (220V) and it was getting a little pricy to heat my garage. The Mr. Heater propane unit works GREAT. It has a cordless option and the btu can run 30,000-60,000. Its extremely quite when its running at 30,000 btu and the unit is cold to the touch. The outside temps here in Michigan are running right around 32 degrees. I run the heater for 30-45 minutes and my inside temp reaches 62 degrees. Very pleased with the unit and would recommend it to anyone considering running a propane heater. Enjoy your turkey!
