Abstract
Six solar domestic hot water systems tested at the National Bureau of Standards have been analyzed. Results indicate that the thermosyphon system delivered the most solar energy to the load per dollar of initial investment (the air system delivered for the least) and that direct systems performed better than indirect systems. Storage losses from the double tank system were greater than expected, and this significantly reduced the relative performance of these systems. Further, the use of pumps, fans, controls, and solenoid valves in the pumped systems can reduce the net energy savings of the solar system by up to 30%. (A)
