wow. Closeups showing a fuzz layer on a furnace. What a concept! And the air quality won't meet IAQ standards ever.
In cold climates, people who want to keep as much of the stored energy in warm moist air as possible before expelling it into the great outdoors, should know about whole-house Heat Recovery Ventilator Air Echangers. A unit costs less than $1000. I've not yet seen any discussion on whether these perform so well as to eliminate the need for bathroom shower ventilation.
