Throws great heat! Designed to heat up to 3,000 so ft of space. However I don't have a big enough tank (requires a 100 b tank or bigger) plus too much heat for my space, designed to operate at full capacity for large spaces, This has a detachable handle & fold out wheels for transporting, I'd trade for a smaller btu (min btu 30,000) heater, has a built in sparker button.
