Do any of you have one of these ventilators installed in your home? I'm looking into the possibility of installing one in the ceiling of the our den, the room where the insert is, to the 2nd floor hallway. It would move the heated air into the main hallway upstairs which connects to the bedrooms. Installation looks fairly easy. It works on a switch which can be hooked up to a thermostat or standard wall switch. I attempted to attach a photo, have to work on it!! Thanks for any input. Jim
