Thermal Performance Evaluation of Combine Solar Water Heater and Gas Geyser System

The solar energy is free energy and available in the ample amount and solar energy can be used for cooking, heating and power generation purpose. In the solar water heater the water which is heated can be used for bath purpose and to maintain temperature in the winter days is difficult and so in the present work the water stored in the insulated tank of solar water heater will be supplied to gas geyser and as water is pre heated so the gas consumption will decrease in case of gas geyser.
