Is there any maintenance required for SWH systems?
Solar Water Heaters once installed requires very little maintenance. Maintenance involves wiping the dust deposited on the glass surface once in 5 days. Wiping the glass every day will help increase the efficiency of the system. Other important thing to be taken care of is to see that the main cold water tank from which water is supplied to the solar tank is always filled up to the level. Use of Automatic Level controller can help in maintaining an optimum level of water.
