«That's huge,» says Maclay, who says he's now able to use
air -
source heat pumps in Vermont's cold climate zone, something that was impossible
just a few years ago.
This is such a clever idea: instead of
just pumping the hot
air out, it is run through an
air source heat pump that condenses the moisture out of the
air on the cold end of the
heat pump, and then recirculates the
air, reheating it with the hot end of the
heat pump.
