Paper Water heating is the need for domestic as well as industry. Heating of water by solar water heating system is present but the system takes more time and losses heat fast in a cloud environment. The objective of the paper is to develop a flat plate collector for solar water heater which can heat the water fast i.e. we can get warm water, hot water as per need. The experiment is carried out with two developed model of flat plate collector and comparative results with conventional model are presented.
