Information regarding generic type, make, and costs of solar domestic water heater (SDWH) systems in the Sacramento, Roseville, and Davis area is reported. Sixteen SDWH installers/do-it-yourself kit dealers were identified and surveyed by phone. The survey participants were divided into three categories: (1) installers in business for one year or longer, (eight firms); (2) installers in business less than one year, (five firms); and (3) SDWH do-it-yourself kit dealers, (three firms). The survey report establishes an average cost for SDWH pump systems for new single family unit production housing (1350 square feet), with hot water demand typical of an average family of four, and roof mounted collectors. For the first two categories, the SDWH system average cost is $2469 (this includes both open loop and heat exchanger systems with circulating pumps). The average cost of the open loop pump system is $2321; whereas, the heat exchanger pump system average cost is $2592. The participants were questioned concerning discounts they would offer to builders purchasing SDWH's in volume. From their responses, an 11% discount for a purchase of ten systems was derived for the first two installers categories. The average cost of an installed SDWH pump system purchased in a volume of ten units is $2201. The average cost of an installed SDWH open loop system is $2066, and a heat exchanger system is $2307. For the third category, the do-it-yourself kit dealers, a 12% discount was derived for a purchase of ten systems. The average cost of a do-it-yourself pump kit when purchased in a volume of ten units is $1481. The average cost of an open loop pump kit is $1386, and a heat exchanger pump kit is $1672.
