My house is old, and crappy windows, so there are lots of air leaks in.

Yea, actually any form of ventilation will work. Just need some make up air coming in. Need to be careful of any heating device, like gas furnace or wood burning devices that require fresh air. One does not want negative pressure in the house.

As long as you vent out stale humid air and bring in some dry fresh air, the idea is the same. However in my climate, without the HRV, the heating bill would sky rocket from heating the cold outside winter air.
