Closed Loop Passive Vacuum Tube Water Heater for pressure system
Tank is closed without exhaust pipe ,the tube complete with heat
pipe and aluminum fins for conduct the heat to tank by cap which
sealed the tank.Tank works with pressure from Tap water.

The solar heater tank has no exhaust hole, therefore, it must bear
the pressure came from tap water and hot water,when use, the hot
water comes out because of water pressure.Vacuum tube absorbs solar
energy, and conductive copper pipe transfers the heat into the
pressurized solar water heater tank. In this case, the water inside
the tank becomes hot.No water in the heat pipe makes the whole
system could bear pressure
Domestic hot water for shower, washing
It Adopts the best conduction performance metal- heat pipe (copper)
and Can be used all year round in the cold climate.It has a High
efficiency, rapid warming. Heat pipe in vacuum tube could transfer
hot energy to cold water in pressurized solar water heater tank
The whole pressure of the system is up to 1.5kg/M2, the inlet could
connect the tap water directly, the max pressure can be 0.6Mpa.No
water in the tube, one tube broken don't influence the system
The design for inner tank is reasonable and scientific, which could
hold 100, 000 times fatigue test without any damage
7.Dual-purpose brackets for both flat and inclined roof
8.The system is pressurized,it keep a constant temperature of water
in the tank, avoid the problem came from water level controller
malfunction which could cause water flow out
