Thru-Wall Room to Room Fan

I own a pellet stove that I have in the basement. I was leaving the door to the cellar open and letting nature bring the heat up. Sometimes the room in the cellar was 80 degrees or more. With this fan mounted at the top of the stairs and exiting into the living room I am getting the heat where I need it and the cellar is cooler. It's a win win. I was having trouble with the fan initially and sent it back for a replacement. I again had problems and worked with the company to figure it all out. They were very patient and I found the problem was mine, not theirs. The fan works as advertised, maybe even better. I encourage anyone that needs to move air from one space to another to purchase this product. - Customer Reviews
