Target: All those who have installed Solar Water Heating Systems on roofs   

 Health authorities, all over the world keep issuing warnings that citizens must boil the water being supplied through taps to avoid water borne diseases.  But we have to use scarce fossil fuels or electricity for killing the bacteria present in the municipal supplied water.  

Boiling water for bathing and drinking:
Many homes in urban/semi-urban areas have installed Solar Water Heating systems.  Such people can use the solar system to get boiling water for drinking minus the harmful bacteria, cool it and be healthy.  In case there is not much of sunlight, by using minimum electricity to heat up the heating element that is provided in the system, one can bring the water in the drum to the boiling point.  Thus,   If we can adopt the following method we get clean and healthy drinking water.

Boiling water for cooking:
If we can adopt the same method and use the hot water for cooking purpose, precious fuel like cooking gas, electricity and consumption of water can be minimised.  This way, we can contribute our might to reduce carbon footprints through burning of fuels for generation of electricity and less consumption of fossil fuels.
