An Experimental Study on Improving the Thermal Storage of ICWS

ABSTRACT-The integrated collector water storage (ICWS) systems are simple type solar water heaters that can be used for the supply of hot water for domestic purposes. The present research is an experimental study on of a storage solar collector.This was done by modifications in the design by (sabah, 2005). The design is simple and low cost compared with other solar water heaters. Giving a capacity of about (210 liter).The collector was tested during the period from February to July (2011), under Baghdad climatic condition. The experimental results show it is possible use to a storage solar collector for domestic hot water applications, where possible heating 210 liter of water to different temperatures depends on stratification phenomenon. It is noted that maximum temperature for 7 February is 51.5 °C and minimum temperature is 31 °C , while the average temperature is 37 ° when is initial temperature of water equals 15.9 °C, This means rise water temperature of 22 °
