I'm sure there is a better brand out there...but I bought 2 of the Entreeair Door Frame Fans to help circulate some the warm air throughout the first floor where my stove is located. At first I was a bit skeptical about how these little fans would work, however I have quickly become an advocate of them. I put 1 in the entry way of my kitchen on the first floor which was not getting warmed up. About 3 hours later, it was noticably warmer, and now about 8 hours later the kitchen is as warm as the rest of the first floor. I put the second fan in my dining room on the first floor (this is the room the stove is in). This doorway leads to the stairway leading to the second floor. Now about 8 hours later, the entire upstairs has warmed up. At heat setting 2, burning Green Team Pellets, the downstairs is at a toasty 74 degrees, and upstairs is at 69 degrees. If anyone is having issues with circulating the heat from the stove throughout the house, I would definately recommend investing in these door frame corner fans. $19.99 at Lowes, and well worth the investment.
