In order to ensure comfort and get the most from the various systems of our house air needs to move around. Our air source heat pump and our heat pump water heater work together in boosting the efficiency, and the ceiling fan is a big part of making that happen. This video explains the relationship between those systems. Thanks to our sponsor Aeratron for providing super efficient and quiet ceiling fans that fit in nicely with the look of this LEED v4 Platinum certified house.
If it were me I'd want a ceiling fan in the older portion of the home as well, certainly if it can be done during other renovations without great effort. An HRV does not provide the same amount of circulation as a ceiling fan does, and without one, warm air will still collect up high; and in the summer a ceiling fan is a quiet and efficient way to provide a cooling sensation. Here is a short video on ceiling fans, they are an integral part of the heating and cooling strategy of our Edelweiss demonstration house.
