Slightly different than others.

We are using it as a temp heat source. My husband showed me how to start it because it isn't as easy as other similar heaters.

Works as advertised!!!

Lights easily by following instructions. The thermostat function is not quite an instant on or off. It seems to work better with each session of use but the fluttering is a bit disconcerting at 1st. So far I've only used it for a light demand on the enclosed porch to bring it up to 68 from high 40's & low 50's. Heat output is great, I set it to high just to see how quick it would heat up a 800cf porch from 48 to 68. Took maybe 10 minutes then I backed it down to 50% and it cycled on and off as advertised. Very quiet compared to the tower style propane heaters without a thermostat. The fan has marginal value but I wouldn't base my purchase on how that worked. The quick disconnect for a 20-30lb remote tank makes life easy also as opposed to changing 1lb tanks. Recommended side and front clearance is accurate for safety. This will definitely make morning coffee on the porch as the sun rises more pleasant in the winter. Worth the money!
