SOLAR WATER HEATERS
EVACUATED TUBE COLLECTOR (ETC)
Solar water heaters use natural sun light to heat water. This system works on the thermosiphon principle and is designed to provide hot water without consuming expensive electricity. This is the most effective way to generate hot water thereby saving costly power and is also environment friendly.
Evacuated Tube Collector works on a simple principle called ‘Black body heat absorption principle’. Solar water heating systems using vacuum tubes made of borosilicate glass with special coating to absorb the solar energy are Termed as “Evacuated Tube Collector (ETC) type systems”.
ETC type Solar Water Heaters are more efficient and cost effective.
