LoginHot water is an essential requirement in most Residence. Gas, electricity and furnace oil are beingused for obtaining hot water. These sources are not readily available and are scarce in a part of Japanat present. Fortunately, solar thermal energy is plentiful which can be successfully harnessed forgetting hot water. In this paper, performance of the copper coil heat exchanger type solar water heaterhas been described, which provides domestic hot water for a four-person family. And energy-savingquantity per annum is about 6609 MJ and the average of yearly conversion efficiency in 2005 was 62%.It is capable of reducing CO2 emission by 9.6 ton-C. And can save $209 carbon tax per year by usingSDWH. The results show that the use of a solar water heater will conserve a lot of conventional fuelswhich are being wasted for merely obtaining hot water and achieve good effect of environment.
