Solar Water Heater - Evacuated Heat Pipe Tubes, Efficient Thermosiphon Passive Heat Exchange Technology

These Solar Water Heater is now a mature technology. Wide spread utilization of solar water heaters can reduce a significant portion of the conventional energy being used for heating water in homes, factories and other commercial & institutional establishments. Internationally, the market for solar water heaters has expanded significantly during the last decade.
MGIT presents ETC based Solar Water heaters.
a c Most vacuum tube collectors use heat pipes for their core instead of passing heat directly through them.
a c Evacuated heat pipe tubes (EHPTa s) are composed of multiple evacuated glass tubes each containing an absorber flat plate to a heat pipe.
a c The heat from the cold end of the heat pipes is transferred to the transfer fluid of a domestic hot water or hydronic space heating system in a heat exchanger which is wrapped in insulation and covered by a sheet metal or plastic case to protect it from the elements.
a c The vacuum that surrounds the outside of the tube generally reduces convection and conduction heat loss to the outside.

Thermosiphon Based ETC Solar Water Heater
a c Thermosiphon refers to a method of passive heat exchange based on natural convection which circulates liquid without the necessity of a mechanical pump.
