- The thermal performance tests and results on the LARGO Solar Hot Water System under natural environmental conditions are presented. Some objectives of these evaluations are to determine the amount of energy collected, the amount of energy delivered to the household as contributed by solar power supplied to operate the system and auxiliary power to maintain tank temperature at proper level, overall system efficiency and to determine temperature distribution within the tank. The tests and evaluation were performed at the Marshall Space Flight Center solar test facility. The Solar Hot Water system is termed a ''Dump-type'' because of the draining system for freeze protection. The solar collector is a single glazed flat plate. An 82-gallon domestic water heater is provided as the energy storage vessel. Water is circulated through the collector and water heater by a 5.3 GPM capacity pump, and control of the pump motor is achieved by a differential temperature controller.
