Might be a little off-topic, but here goes:
With Winter fast approaching (got to get that extra snoblower put back together), I got to thinking about how much I am heating the backyard with my dryer.
Has anyone put together a heat exchanger for capturing some of this heat before it goes outside? I know I can't just vent the dryer inside (humid air, dust, and combustion gases), but someone must have done this before.
