Experimental Study On Solar Hot Water Heating System

Thriving towards renewable energy is an optimum process to mitigate environmental problems such as climate change. Any source of energy that is harnessed from renewable resources is considered as a green source of energy. These referred sources are naturally replenished within human's timescale such as rain, wind and sunlight. This research aims to investigate experimentally the utilization of solar energy in heating systems. Two systems were investigated; water to water (WTW) system and water to oil (WTO) system, which uses thermal oil to transfer heat to water. A feasibility study has been conducted to evaluate the two systems in order to investigate which one is the most optimal solution. Based on the performed calculations, it was found that WTO method is more efficient in terms of producing sufficient heat and reducing piping material, the length of the pipes has decreased from 78.78 to 7.13 meter when switched from WTW to WTO method.
