This durable indoor safe portable radiant space heater runs quietly on a 1lb cylinder propane tank and doesn't require any electricity. Giving you up to 5.3 hours of heat per tank max, Heat Hog is a new breed of portable heater with features that set it apart: The fixed 45-degree angled heat head directs warmth where you need it most. Our curved plaque provides a 33° wider heating area than a standard portable propane heater. That means more of your herd can enjoy the heat.
