In our modern societies, One of the main and simplest signature traits is hot water as a convenient and efficient way of life either for industrial and domestic purposes, however, obtaining hot water in most cases will be through fossil fuel either by direct burning for the fuel for heating or indirectly by using electricity that generated by fossil fuel. Using solar heaters will limit the in some extent the usage of fossil fuel. A flat solar water heater of (165 to 175) cm3 has been constructed to be used as a model for educational purposes. The solar heater is made of local materials consist of galvanized iron pipes, glass surfaces, wool insulation, aluminum frame, and fixed iron base. Moreover, Thermocouples, pyranometer, and an anemometer were used to test the performance of the heater in four days in May for the angle of inclination of the complex 320 is on the horizontal. In conclusion, the daily average efficiency was around 57%. The temperature in the tank is about  62 0C at noon, which is sufficient for home use throughout the day.

Abstract In the present work, a solar humidifier suitable for solar thermal energy-driven humidification–dehumidification desalination has been proposed and experimentally investigated. The proposed solar humidifier compacts the solar heater and humidifier into a single component while reducing energy costs by utilizing solar thermal energy. Several local flow storage and distributor elements are created in the absorber surface that produces a “dam effect” in combination with stainless steel mesh and airflow baffles. The effect of varying flowrates of air and water, inlet water temperature as well as inlet relative humidity on the performance of the solar humidifier is investigated. Humidity based normalized gain (NGhumidity) versus solar humidifier efficiency curve, which depicts a heat and mass performance of the solar humidifier, is reported. This curve is analogous to the normalized gain versus collector efficiency curve of the solar water/air heater. The productivity of the present system is compared with the published results of similar studies. Best mean productivity of 838.5 g/m2/h and best instantaneous productivity of 955.2 g/m2/h were achieved using a present solar humidifier, showcasing the effectiveness of the proposed approach. The comparison of the performance of the solar humidifier with the performance of conventional configuration having separate heating and humidification is also carried out. It was found that the investigated solar humidifier (internal heating configuration) does perform the same in terms of utilization of solar energy for evaporation, if not better, than the conventional separate humidifier and heater (external heating configuration).
