Solar Water Heater

MGIT Solar Water heaters.

Solar Water Heating 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.

• Most vacuum tube collectors use heat pipes for their core instead of passing heat directly through them.

• Evacuated heat pipe tubes (EHPT’s) are composed of multiple evacuated glass tubes each containing an absorber flat plate to a heat pipe.

• 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.

• 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

• Thermosiphon refers to a method of passive heat exchange based on natural convection which circulates liquid without the necessity of a mechanical pump.

• This circulation can either be open-loop as well as when liquid in a holding tank is passed in one direction via a heat transfer tube mounted at the bottom of the tank to distribution point – even one mounted above the originating tank, or it can be a vertical closed loop circuit with return to the original vessel.

• Its purpose is to simplify the pumping of liquid and / or heat transfer, by avoiding the cost and complexity of a conventional mechanical pump.
