I looked at a few air to air heat exchanger bath fans that are out there, they tend to cost $300 or so and they shut down the heat exchanger once the temp drops below 20F to prevent ice up.
But I agree, we need to look for the best solution, not just the cheapest, that is why I was wondering about just keeping the house sealed tight and making sure it's conditioned properly to prevent damage to the bath room, also because bath rooms tend to have moisture problems even if there are vent fans.

My neighber has moisture issues in their master bath room because of the complex shape of the room and a large walk in shower that takes a while to dry out and I think I've talked him in to trying the dehumidifier in the bath room to dry it out, paired with my kill-a-watt we will find out how much per month it really would cost to keep a good sized bath room dry, the hard part is figuring out the resources saved by not having to remodel the bath room due to mold and mildew over the years.
