1. It can withstand pressure of tap water when it works, and copper coil in tank bear pressure.
2. Use in any time: it adopts advanced design idea and integrates with high efficiency preheated patent technique.
3. High quality SUS304-2B stainless steel for inner water tank, processed by argon arc welding technique, under
strict quality control system, tank will never rust and leak.
4. Relevant accessories are optional instead of compulsory, client can choose some or none according to actual need.
5. 6. It can produce hot water with constant temperature.
7. It’s indirect solar system, so water quality is superior, much cleaner than direct solar system.
8. Time of uploading water is cut, 24 hours water supply on condition that pipeline is working.
9. Life duration: 15 years, warranty: 5 years
10. OEM/ODM offered
Good water quality
It use tap water directly, live water but not sedimentary water.
The thick of coil is 0.8mm, which can withstand 6-12 bar.
A feed tank on the top, it will supply water automatically. What you need is just to open tap and have a wash.
No scale, high efficiency
Water in the tank wouldn't be used just to heat the coil, the water in the tank will keep hot and no scale. The vacuum tubes will be kept clean, and system has a higher efficiency than normal system.
Total 3 valves in whole system only, very simple and safety, maintenance free.
Because of all hot water in main tank, the feed tank won't be frozen. It can be working well in -10deg.C. - good performance in rainy & cloudy days
When tap water comes in and out, it will be just 3deg.C less than water in tank. Viz. if 90deg.C in tank, the outlet water will be at 87deg.C after exchanging.
If tank water is 90deg.C, and you catch rainy days, no problem, if you use 50L 40deg.C water per day, you can keep getting such hot water for 15 days!!
The electric heater is only backup, we don't use it anytime practically, except in winter.
Because the water in tank doesn't be used, in fact the circulation is not only water in the tank but also water in the tube. So for example 300L, actually it has 400L in whole system.
The vacuum tubes absorb the sunlight and turn it into the heat energy, heating the water in the tubes. Depend on the thermo siphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
People do not use the water from the water tank directly. The cold water comes into the copper exchanger, be heated, then goes out from other side for people use.
