Experimental Investigation of Inserted Twisted Tape Pitch Effect in Evacuated Solar Water Heater

Although productivity and manufacturing may always be met simply through the use of energy, the availability of energy is crucial in economic activity. These days, limited energy is needed for any country ’s economic growth; however, so because large number of energy is still retrieved from fossil fuels, nations with insufficient quantities of such fossil fuels confront various problems of unemployment; however, the remedy to this energy crisis can be found in alternate solution energy such as solar, wind and biomass; even so, alternative sources such as solar, wind and biomass are not yet available; even so, alternate solution for energy such as solar, wind, and biomass are not yet available This research aims to determine how the height of twisted insertion tape influences the performance of evacuated tube solar water heaters.
