Performance and testing of improved natural circulation type solar water heater in Arid areas

Abstract A conventional natural circulation type solar water heater has been improved upon by eliminating the float valve and using a sealed pressure tank instead of an open tank. Performance of the improved natural circulation type solar water heater has been compared with and without solar-selective surfaces. The detailed design, fabrication and testing have been reported in this paper. The efficiency of the improved natural circulation type solar water heater with and without solar-selective surfaces is 57.5 and 51.0%, respectively.
