Abstract

Results are reported on the performance of a solar hot water system fitted with the spontaneous downward heat transport system previously tested at the technical scale. The vertical distance between the collectors (2.8m2) and the heat exchanger is 8.5 m. The overall efficiency is found to be about the same as expected from a conventional system with a differential thermostat and circulation pump. Moreover, there are the advantages of no maintenance, an extremely high reliability (the system has been in operation now for 1yr without any fault) and independence from the availability of electrical energy for the control and pump.
