A review of solar water heating systems for domestic and industrial applications is presented. They are grouped into two broad categories as passive and active solar water heating systems. Each of them operates in either direct or indirect mode. Their performances, uses and applications, and factors considered for their selection are reported. The active systems generally have higher efficiencies, their values being 35%–80% higher than those of the passive systems. They are more complex and expensive. Accordingly, they are most suited for industrial applications where the load demand is quite high or in applications where the collector and service water storage tank need not be close to each other or for the applications in which the load requires more than one solar collector. On the other hand, the passive systems are less expensive and easier to construct and install. They are most suitable for domestic applications and in applications where load demand is low or medium. Generally more research and development work are needed to further improve the existing level of efficiency for it to serve effectively as a viable alternative to the conventional means of hot water generation. The actual field testing experiences, together with the prospects and economic problems that affect popularization of the systems, are also presented. Their possible solutions are suggested.

The significant advantages of thermosyphon solar water heaters in terms of simplicity, reliability, and cost have long been recognized. In addition, experimental studies have indicated that the thermal performance of thermosyphons is comparable to that of active systems.

In this review, thermosyphon solar water heaters are classified and the results from the experimental determination of system performance along with mathematical modelling are presented. Storage tanks with and without heat exchangers (direct and indirect systems) are considered. The literature on thermosyphon solar water heaters is reviewed and important results are discussed. Detailed consideration is given to the effects of reverse flow, stratification in the storage tank, flow resistance arising from various components, withdrawal of water from the storage tank, storage tank elevation, circulating fluid, etc.
