I got a split level with a very good fireplace insert on the bottom floor (believe me when I say that it's BTUs are sufficient to heat the whole house - if I could only get it circulated around the house). When I crank up the fireplace in the den, the den gets very toasty and the upstairs stays very cold. Yes, I know that I could turn on just the fan of my central heat, but that seems a little silly to suck hot air from the house to the outside unit and then back (probably a good
40 feet round trip) just to circulate the air. This is especially a bad idea due to the minimum insulation in the area where the air reverses course (at the heat exchanger on the outside unit) Yes, I also am well aware that heat rises and should just "naturally" go up the stairs, but the den would be melting before that type of heat exchange happens to a sufficient level to heat the upstairs. All I need is a small squirrel cage fan (i.e., quiet) that is made to fit between the ceiling and the floor. Bathroom fans are typically too noisey. Anyone know where I can get this beast?Thanks.
