- 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.
Principle:
The vacuum tubes absorb the sun’s rays and turn the rays into energy, heating the water in the tubes. As the temperature of the
water is rising, The density turns slightly, then the hot water in the tubes floats into the tank, and the cold water in the tank
goes down to the tubes. Keeping natural cycling like this, the water in the tank will be heated.
The vacuum tubes heat the water in the tank, but the users do not use the water in it directly. The cold water comes into the
exchanger from one side and the hot water heated by the exchanger, and then the hot water comes out from the other side for use.
The Solar Water heater tank is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank
should always be filled with water to avoid damage caused by dry high temperature working conditions. The stainless steel our use
belong to food grade, and SUS 304 & SUS 316 have better corrosion resistance.
Thermal Performance
The system passes over thermal performance test according to EN12976-2:2006-chapter 5.8, parts of the test conditions are listed below:
