The uniquely designed FPC (flat plate collector) Type Solar Water Heater is an environment friendly means of water heating. In this system two pumps are used for circulating water between system insulated tank and collector bank. The pump is controlled using DTC (differential temperature controller), which is fitted inside the control panel. The DTC is used for sensing hot and cold temperature through sensors. One sensor is fitted at the bottom of tank and senses cold water and second is fitted at the top of the last collector of the row in the collector bank, it senses hot water inside the collector. The system is known for high performance, easy installation and long service life.
