Description:
Solar& Electric
This type non-pressurized vaccum tube solar water heater has a assistant tank in the top of main water tank. The assistant tank can automatically supply cold water. It works with pressure up to 0.2 Mpa and can normally work in all climate. The absorptive coating is ALN/ALN-SS/CU. This coating has high absorbing ratio(0.94) and low emission ratio(0.6). The heat efficiency is 0.64. The life span of the vaccum tube is 15 years. The vaccum tube is made of borosilicate 3.3.
Characteristics:
1. It is not easy to be frozen and cracked down even in hash weather.
2. The shortcoming of bursting of tube or water leakage due to aged rubber ring is eradicated;
3. The water tank is welded scientifically under the high frequency weld and argon-arc weld. The non-pressurized vaccum tube can be directly connected with tap water system to operate automatically with pressure-bearing.
4. Water proof grade: IP *4
5. Hot water can be used directly, or can be used as a pre-heat.
6. Electric heater can be used 1500W or 3000W

Specification:
1. The inner tank is made of SUS304-2B stainless steel (thickness: 0.3mm-0.6mm). There is copper coil(optional) in the tank, and the heat water just come from the copper not from the tank;
2. The outer tank is made of stainless steel. (thickness: 0.3mm-0.6mm). The assistant tank is also made of stainless steel
3. Heat insulation layer: Imported PU(thickness: 55-60mm).
4. The normal size of vaccum tube is 58mm*1800 and 47mm*1500mm.
5. The bracket is made of stainless steel with power painting (thickness: 1.2mm-1.5mm).
6. Bracket degree: 45 /38 degree(normal). The actual value can be adjusted according to your latitude.
7. Rated Voltage of electric heater: 220V or 110V
