About the system
Geothermal resources in Cascade can be used to heat and cool buildings throughout town in a networked two-pipe system. The temperature in the loop system is modulated by water from existing geothermal wells in Cascade that produce water in the range of 50-98F. Each of the commercial and residential buildings served by the loop will have heat pump(s) to either take or put heat into the loop. Supply water would be served by one side and return or discharge water by the other side.
Expected high temperatures from the system are in the 70’s in winter and expected low temperatures in the 50’s in summer. This centralized distribution system avoids the thousands of penetrations required for individual geothermal heat pump systems.
