Abstract
In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. A solar water heater is a device that can be used to capture sunlight in order to heat the water in your pipes to be used for baths, showers; etc. Solar water heater plays an important role in energy conservation. Because of its efficiency is comparatively more than the electrical energy conversion. Solar water heater is a very simple device and efficient way to absorb energy from the sun rays and use it. In this work design improvement of solar water heating temperature up to bathing in home and nursing home applications above home temperature method always follows an orderly step-by-step process. Finally compared analysis results with electric water heater materials and solar water heater materials. The solar collector model thus produced was put to test by simulated effect of radiation due to sun , while circulating water through it at constant mass flow rates , the evacuated tubes are imparted with fin .The SWH efficiency was as high as 56% as compared to SWE with simple tube . These types of solar water heaters can easily be used to heat pool water. A flow rate comparable to that of 0.2 Lpm is best for heating. The heaters are to be used intermittently for heating a batch of water till 15-20 minutes until the efficiency drops down and then fresh water be circulated through it. A cycle like this would give us the maximum output in minimum time.
