Stainless steel inner tank, pressurized system integrated with immersion heater, controller, P/T valve, check valve etc. Let SFH consider more for you!
This is a passive, thermosiphon, heat pipe, system. It has no moving parts and is the latest, most efficient technology.
This is a very high-tech version of a black garden hose laying in the sun. Water inside the hose gets very hot.
Cold water, which normally enters your water heater in the house, is diverted through a pipe into the food-grade stainless steel tank on top of the collector tubes. Sunlight heates a fluid in the middle of the sealed glass collector tubes. The heated fluid rises to the top of the tube where it heats a copper rod. The rod fits into a copper nipple in the white storage tank. Inside the tank, water surrounding the nipple gets hot. When you turn on a faucet in the house, cold water flows in one side of the storage tank, forcing hot water out the other side and into the house.
Drinking water never comes in contact with the collector tubes, so there is no chance of anything toxic getting into your water. If a tube breaks, the rest of the tubes keep working and there's no leak because the nipple seals the tank.
1) Connect with tap water piping directly. Water is feed automatically by the water pressure. The vacuum tubes absorb the sun energy and transfer the heat to the tank via the copper heat pipe and the water temperature of tank is gradually heated.
2) If the water is expand and pressure rise to more than 6 bar. The P/T valve will release automatically.
3) The electric heater can be operated for backup heating.
Compact Heat pipe pressurized solar water heater Feature:
1) Superior heat preservation ensured by 55mm polyurethane foam insulation layer
2) Designing the immersion heater hole in advance for the cloudy, snowy, and rainy days
3) Suitable for mains pressure water (up to 0.6MPa)
4) Immersion heater connects with SFH water tank
5) Material: galvanized sheet
6) Inner tank material: using pressurized material, the inner tank has the advantages as follows:
a) No corrosion: can prevent corrosion lead from chlorine ion, sea water, salt water or buck water.
b) No leakage: applied for special anti-corrosion layer
c) Sanitary water: the qualities showed above make it possible that waterquality is pure and no twice pollution
7) Able to be used in all climates
8) Automatic water supply, could supply water self-acting without any other installation and could able to be pressured.
