Abstract:
Due to the depletion of natural resources including natural gas there is a demand to develop new methods and techniques to efficiently use the existing resources. Gas geysers are being used for water heating at homes and on commercial scale. These geysers are cheap and being used most widely all over the country. These gas geysers are not efficient enough. Solar heating units are expensive as compared to traditional gas geysers, so people are forced using these currently inefficient gas geysers. We are providing a midway solution. A way is being devised to save gas consumption by improving the efficiency of geyser while analyzing existing ways being used to do so. Minimizing the fuel consumption to reach the desirable temperature will be achieved by preheating of water. This was done using submersible helical coil (copper tube) wrapped around the exhaust. An efficiency improvement of 2.2% was observed. A payback period of 1.5 years has been worked out. The results obtained from our working prototype are used to compare the efficiency improvement from the existing gas geysers.
