I hope this is in the right place...
Just wondering about this idea or if anyone is doing/ has even heard of it?
Since a Heat pump is basically Air Conditioning the outdoors when it runs, why not make a surround for it and duct it into your house or garage(it would have to be near it, like a central A/C). Then have another duct going out the top into your house blowing the cool air. I suppose you could even locate the unit in your basement/garage so the ducting would be simpler.
It just seems like such a waste to run a heat pump to heat the pool and then run an air condioner to cool the inside when you could do both in one unit. I think this would be very effective as a workshop/garage cooler, or even with ducting, could be rigged to blow on you under a cabana/covered patio and keep you cool when you're serving drinks, or enjoying them. 8)
