As I said in my original reply, I live in northern Canada (I can drive into Alaska in about 4 hours) and the heat loss I experience, while noticeable, is not enough to concern me. I originally thought I'd vent outside in the summer, and live with having to constantly clean my filter during the winter. And yet, when winter came, I found that I could continue to just vent outside.
I don't run my dust collector all day, but continuous usage of 1 - 3 hours on any given day is not unusual, and cumulative usage of short duration (say 5 minutes) over any given day can be over 4 hours (all of the preceeding usage estimations, of course, are dependant upon what I'm doing that day).
