    Hi all – Happy new year. Question: Can a ground-based geothermal system be used as a water chiller?

    Background: Arizona :)

    More background: In Tucson and Phoenix, there's no such thing as a cold shower during the (long) summers. We get to choose between warm and hot water. Cold showers have many uses, including as a promising treatment for depression. It would be nice to have the option of cold showers year-round.

    I'm new to geothermal, and I know that the heat pumps can be reversed in some sense, but I'm not sure if they or the desuperheaters can be used to chill water specifically. Thanks for your help.

    Sure, get a water to water heatpump and activate the reversing valve to make chilled water. We sometimes do that to provide chilled water to air handlers for A/C. How cold is your ground water coming in?

    Thanks for the info. My ground water is somewhere in the 70s to 80s F.
