I would like to hear how you make out with the HRV this winter. Last fall I installed a Humidex unit (
http://humidex.ca/index.htm) to replace my dehumidfier as well as its operating cost. It is quite cheap and easy to install. Have any others tried it? The Humidex unit is a very simple concept, drawing cool and moist air from the floor and venting it to the outdoors. It is very quiet and kept my humidity level between 40 - 60 percent all winter and throughout the dog days of summer. It is fine, but as I continue to add tanks to my fleet...the humidity will become more intense. The next step may be an HRV.
