Solar water heater with sealed copper heat pipes.  Complete stainless steel inner tank and outer tanks, aluminum stand, pressure relief vent, water inlet and outlet fittings, tank cover, foot cushions, end caps and reflectors included.  This complete, independent hot water system for a house is ready to use when water is supplied. 

Copper heat pipes are the most efficient of all heat pipes offered, so this premium model offers more heating per tube than the all-glass heat pipe model and is also slightly more robust. Vacuum tubes can never freeze, since they contain no water. Optional auxiliary electric heater and controller can keep water temperature constant.
