Solar Water Heater

A very useful device to heat the water for domestic, industries hotel, hostels, hospitals. Now a days it is very much popular in India where good solar energy is available. Till today we have installed number of solar water heaters for builders , hotels, hospitals, individual bungalows , industries. Solar systems could coated after understanding site conditions however small capacity of systems normally used for residential purpose, are available ex stock.
Operating principle, - There are two types of solar water heating systems , one is thermo-siphon the other one is forced type systems 

Thermo-siphon - in which with the use of solar energy , water gets heated in solar collectors results, density of water reduces and became lighted than cold water. Cold water being heavier than hot water , it pushed hot water into the tank , in this way hot water gets circulated by thermo siphoning , The storage tank being insulated , water remains hot till next day . In this system maximum temperature of 70 degree could be achieved

Forced Systems water gets heated in solar collectors with the use of solar energy , In this type of systems water is circulated through the panels using electrical pump. This type of systems normally used where the system capacity is large ( more than 5000lit/ day )
