300L Presssure Solar Water Heater 304 Stainless Steel 250L Solar Heating System


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. Adopts the best conduction performance metal- heat pipe (copper).
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 rapidly.
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 0.6Mpa.
5. No water in the tube, one tube broken don't influence the system working.
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.
