Don’t know if you can tell it with the fan blades turning but this fan is pushing air into the dining and living rooms. I had heard about these before and had seen one at an amish store and we were having trouble with cool spots in the living room. This little fan has warmed up the living room alot already and doesn’t use a drop of electricity. We also got a book on how to install the water jacket in the wood cookstove from Lehmans non electric store. As soon as I get it all figured out we should be producing enough non natural gas hot water for year round. CU’s really going to not like this!
