Solar energy is a best source of energy as it is free and green but, the equipments we are using to utilise solar energy are not effective enough. The main focus carried out today is toward increasing performance of solar equipments . Solar water heater is one of them and a very useful equipment because of so many uses of heated water in daily life. So many trials have been carried out to improve it's performance. The performance of solar water heater can be improved by many way and one of them is to reduce the losses from heated water. A trial is carried out here to improve the performance of Solar water heater with evacuated tube collector by filling carbon dioxide gas in the space between evacuated tubes and a glass cover above it. As carbon dioxide is a green house gas , it has tendency to absorb high wavelength radiation that can be emitted from high temperature water inside the evacuated tube.On other side it will not affect the radiative energy going toward the evacuated tubes as it is of shorter wavelength because of tremendous high temperature of sun. The absorbed heat by carbon dioxide gas can be utilized by cold water to be preheated before passing through evacuated tubes or for low temperature water requirements. The heated carbon dioxide cover will also provide a warmer atmosphere to it in case of short cloudy period between sunny day. Thus by utilizing the lost heat performance can be improved.
