A Brief History of Geothermal District Heating in Idaho
Figure 1. Schematic of a geothermal district heating system
District heating systems deliver steam or hot water to multiple buildings for climate control. There are eight distinct geothermal district heating systems in Idaho:
Figure 2. District heating systems that are currently in operation.
The four systems in the Boise area withdraw approximately 700 million gallons of geothermal water per year to heat about 300 homes, government buildings, and businesses. About 60 percent of the water is re-injected back into the aquifer.
The three systems in Twin Falls County are used to heat homes, college buildings, an elementary school, and the Twin Falls Community swimming pool.
The district heating system in Ketchum keeps about 60 homes warm.
At least 10 other areas in Idaho have been studied for potential district heating operations.
