I was wondering if there is a product that would recirculate the hot air from our electric dryer (that vents to the outside) back into our house. The vent trap door seems to stick open and lets a lot of cold air into the laundry room. We were hoping to install this ourselves. We have only seen one type of item on the market,but it still vents the heat to the outside while keeping cold air out.I'd appreciate a response asap. Thanks!
