weirdhellokitty Posted May 19, 2004 Report Share Posted May 19, 2004 Please help We want to install a ceiling bathroom fan in our 2nd floor bathroom. The ceiling level is above the roof level, so we have to vent through the soffit or through the roof. I heard conflicting reports regarding venting through soffits. We have a nice Panasonic WhisperFit Fan, and one electrician said that venting through a soffit was no problem, since the fan comes with a damper which will reduce the backdraft. My primary concerns are moisture condensation and heat loss. We live in Wisconsin. Can we vent through the soffit? We certainly do not want to deal with mold down the road. What should i do? Thanks!

DonTx Posted May 20, 2004 Report Share Posted May 20, 2004 WHK, someone will post a picture soon showing you what happens when you vent a bathroom fan to the soffits. Who ever has that picture, please post it again for WHK's sake. Donald Quote Link to comment Share on other sites More sharing options...

Since I became the municipal code inspector, this is no longer being done. WHK...just save yourself the grief and vent to the true outside as the code states.
