How to Save Money on the Bath Fans
For the last, probably 20 years, bath fans already have been set in the code and if your house not much older than that most likely that you have one bath fan in every bathroom. Of course it’s very important to have them. You can find a lot of information how important to have them in the house, such as: “Moisture can be a problem in the bathroom. It can cause paint to peel, doors to warp and the accumulation of mold spores. A simple exhaust fan can greatly reduce or eliminate the many problems created by excess moisture”. But believe me nobody tells you that through the bath fan you loose a lot of energy!
Several years ago I looked at the soffit cap where the bath fan exhaust is terminated and saw a couple icicles hanging down! I knew that that bath fan never been running because it in the laundry room. I walk around the house and found out that I have the same icicles on the other soffit caps. So, I’ve decided to save some energy and of course money and put pieces 
of paper between the unit cover and casing of the fan. But I didn’t block the air completely to prevent the motor from overheating if I or somebody else in my family turns the fan on.
Of course this energy saving tip is not for everybody. If you spend hours in the bathtub, or very smell sensitive you need the bath fan running in full strength, otherwise this energy saving tip can significantly increase your furnace idle cycle.
If you decide to use this energy saving tip in your house or you may have difficulties with the bath fan installation, for example when you are finishing your basement off, if it’s happens, just let me know and I will explain what to do. Furthermore for the first one of you I will do it for free because with your help I will make a special page dedicated to this issue!
