So I live in Wisconsin and it's a bit chilly during winter here, so if I vent out my steam I'm concerned with the cold air coming back in if I create a return vent, which I pretty much have to because of negative pressure right?
Thoughts? Has anyone else done this? Have other people used systems like an HRV to try to recycle the heat in the air?
