Features
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.
Pressure endurance
The thick of coil is 0.8mm, which can withstand 6-12 bar.
Working automatically
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.
Simple structure
Total 3 valves in whole system only, very simple and safety,
maintenance free.
Anti-freezing
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.
More capacity
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.
Working principle:
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.
