Features:
1) Patent backflow-proof inlet device (ZL 02 2 15723.9):
a) Can thoroughly exterminate hot water backflow if the water supply system stops
working
b) Prevents the heating element from heating without water, which ensures the
safety and extends services life
c) Increases utilization rate of hot water and improves the performance
2) Patent safety energy-saving valves (ZL 03 2 28638.4):
a) Multi-functional: insulation, thermal insulation and excess voltage prevention,
which could provide strong protections to the water heater
b) Can automatically isolate the inside hot water from the outside cold water at the
inlet / outlet to reduce heat loss and improve heating efficiency evidently, which
makes the heater safer and saves more energy
3) Surface thermostat:
a) Uses Germanic EGO surface thermostat first
b) Convenient to operate with high precision and safety
4) Quality super thick steel plate:
a) Thickness: 3mm
b) Shaped by automatic bending roll machine and matched with imported program-
controlled welding facilities
c) Can ensure the excellent pressure-bearing ability of vitreous enamel tank (it has
passed the fatigue test of over 200,000 times and reaches the crack pressure to
45kgf/sqcm)
