1. The pressurized water 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.
2. Vacuum tube absorbs solar energy, and conductive copper pipe
transfers the heat into the pressurized water tank. In this case,
the water inside the tank becomes hot.
3. No water in the heat pipe makes the whole system could bear
1. Adopts the best conduction performance metal- heat pipe
2. Can be used all year round in the cold climate.
3. High efficiency, rapid warming. Heat pipe in vacuum tube could
transfer hot energy to cold water in pressurized water tank
4. 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
5. No water in the tube, one tube broken don't influence the system
6. 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.
1. The pressure of hot water is pressure of tap water directly ,you
can enjoy more comfortable shower.
2. Hot water that we use flow in copper coil without transferring
in tank directly ,so the water is more clean and healthy.
3. There is no need to wait , you can enjoy instant hot water at
any time .
4. It is suitable for some area special with bad water quality such
as hard water ,impurity water etc.We only need use high quality
water in tank as a thermal source,refresh it during some time in
interval.This will increase vacuum tube heat efficiency and in ease
whole system life performance.
5. Can be used all year round in the cold climate.
6. Simple structure, easy to assembly and install, diffuse flat
plate reflector can be assembled easily with its module structure.
1. Lead-time:7-15 working days after receiving payment.
