Efficiency Evaluation of Heat Exchanger Based Domestic Solar Water Heater - A Review

In this paper an attempt has been made to review the literature of performance improving techniques for solar water heater. In view of energy crisis, the application of solar energy in the form of solar water heater is most useful for domestic, commercial and industrial purpose but it is found that the application of its limited due to its demerits. Hence attempt to be made to find out the demerits of solar water heater and improve its performance so that it becomes more popular in domestic, commercial, as well as in industrial applications. The main objective of this research paper is to present the current status and future aspects of Solar water heater in the world by comprehensively reviewing various solar water heater related studies. This review paper shows comprehensive review and researches on solar water heater by various researchers of the world.
