Air Sealing
The best way to reduce your utility bills is to eliminate air leaks in your house. I want to tell you about an existing product that offers an additional way to save energy that many homeowners do not know about. The Larson Fan Company offers a replacement fan assembly that has an automatic, built in damper for the most common bathroom ventilation fans in this country. Their product has a true damper, not a flimsy flap that is design to let air out when the fan is running.
When the fan is not running, which is most of the time on average, the damper is close, keeping warm air in the house during winter or hot humid air out during the summer. That reduces the amount of time your heating or cooling equipment needs to run, and that lowers your energy usage and utility bills. It really is a simple concept and will save the most when central air is being used because cooling uses more energy than heating. This is a great DIY project with a low upfront cost, easy installation from inside the house that you can do in about five minutes. |

Getgreener,
Welcome ! We lived in Michigan some 30 years ago (Durand and East Lansing). Great suggestion on the Larson fan. A good alternative if you can't get the scratch together for an heat recovery ventilaror (HRV). Just finished a home where we put four of the Panasonic units in. Steve

Could something like this work to prevent heat loss for bath fans?

I agree with you a dryer flap should be enough. But for the dryer this product is really worth a closer look it works very well. |

It seems the bath fans I've installed include a backdraft damper (cheap broan fans). The last one I used had one, and I also included a dryer flap outlet as it was vented out the wall (1st floor bath).

I would certainly think so.
