Daystar Corporation installed a solar/electric domestic water heating system in the Borda Wing of the South County Hospital, Wakefield, R.I. in 1975. Initial performance measurements showed that the overall water heating system efficiency was approximately 35 percent. To deliver one unit of hot water ''at the faucet'' required three units of energy input. This study was undertaken to identify the losses which caused this low efficiency and possible improvements which could be made at the South County installation and in future similar installations.
