A Review Paper on Solar Water Heater by Evacuated Tube
Keywords:
Solar, Water heater, Evacuated tube, etc.Abstract
Solar water heater by evacuated tube uses evacuated tube solar collector which is more efficient than flat plate collector.
In this evacuated tube copper heat pipe is filled with non-toxic liquid. As sun heats the liquid it vaporize and rise to the top of the heat
pipe and it cause heating the water passing around it. This system has good thermal efficiency and low maintenance. Conductive and
convective heat loss is very low in this system. Result of less heat loss is fast heating of water as compared to flat plate solar water
heater etc
