Abstract
The water-heating system is considered one of the largest energy consumers in the commercial building sector. The advancement of water heating systems powered by renewable energy sources has become pivotal. The low cost and ease of maintenance of solar collectors for water heating systems have already made them popular for both residential and commercial applications. Therefore, the present study focused on an innovative design of a domestic water heater system. The system consists of a solar collector with a selective, black-nickel-coated spiral pipe and a storage tank. Selective coating can increasing the thermal efficiency of the collector. Temperature variations, useful energy gains, and the efficiency of a solar water heater are analysed numerically. The discussion section of this article provides detailed demonstrations of these key parameters.
