Default Why aren't heat pumps placed indoors ?

you can get ground water heat pumps, they cost more but are way more

This is a region specific temperature. Different parts ofthe country
have WILDLY different ground water temps. Some areas around the Great
Lakes have winter temps that hover very near freezing, while regions
along the Gulf Coast have year round water temps of 75 degrees.

Generalizations are DANGEROUS.

And yes, GSHPs are located indoors.
