Publisher Summary Thermosyphonic solar water collectors are bulky and require large roof surface area for installation because of its separate storage and collector units. The integrated collector storage solar water heater (ICS) is compact and easier to install. The two types of solar water heaters are locally made and tested. The chapter describes the comparison of performance of both systems along with their economic feasibility. The results so obtained also show that ICS that are built from locally available material is inferior to the locally built thermosyphon system in its performance and economic feasibility. The ICS has higher efficiency at lower hot water temperature and vice versa when compared to the thermosyphon solar system.
