1.Water is fed automatically by the
water pressure. 2. A heat
exchanger is built in top of the inner tank,which is made of
straight copper pipe rather than
copper coil. This innovation improves the thermal efficiency
extremely. 3.Antifreezing,working excellently
in the winter. 4.Heat insulation is *0mm
thick,Long time heat
preservation. 5.No incrustant for the
lifetime. 6.High quality,no maintenance or
after-sales service is needed. 7.Fresh and drinkable water
quality. 8.Multiple connections is available
for huge projects. 9.Lifespan is at least *5 years.
Five years warranty for the whole machine.
How it
works: 1.The vacuum tubes absorb the
sunlights and heat the water in the tank. 2.The heat exchanger absorbs the
heat of the hot water in the tank. 3.The inlet cold water is heated by
the heat exchanger. 4.Hot water out.
