Abstract
Geothermal district heating systems are now quite common in the Western U.S. A recent survey identified a total of 17 such systems. The performance of materials and equipment in 13 of these systems is reviewed in this paper. Specific areas covered include: production facilities, central plants, distribution, customer connection, metering and disposal. Those areas characterized by the highest incidence of problems include: production well pumps, customer branch piping and energy metering.
