Funny I was just recommending air exchange heat pumps in another thread and I find their well covered here.
They are one of the most effective ways to reduce our oil consumption drastically.
I installed a MitsFD12 in Nov 08 and love it. We get way more use out of it fo heating than cooling. Just use it in summer when RH is heading for 60.
