Product Description

Heat Pipe Vacuum Tube Three-target glass tube with aluminum fins and red copper heat pipes creates an efficient heat exchange environment, achieving 55% higher efficiency in summer and 42% in winter compared to standard tubes.
Inner Water Tank Utilizes thickened food-grade SUS304-2B stainless steel. Advanced automatic argon-arc welding ensures a service life of over 30 years while keeping water clean and drinkable.
Insulation Layer Features high-density polyurethane integrated foam with twice slaking treatment for superior heat retention.
Supporting Bracket Available in stainless steel or aluminum alloy. Designed for wind resistance (up to 140 km/hr) and corrosion resistance against acid rain. Suitable for both flat and slope roofs.
Optional Devices Equippable with electrical heaters for cloudy days, intelligent controllers with temperature sensors, and magnesium bars to soften hard water and prevent scale.
Warranty 3 years international responsibility for integrated system exchange and 15 years for vacuum tube compensation regarding quality issues.

Frequently Asked Questions

How does the pressurized system differ from non-pressurized?
Pressurized systems can be connected directly to tap water and withstand over 6 Bar pressure, providing more comfortable hot water flow without requiring a header tank.
Will the system work during very cold winters?
Yes, the copper heat pipe technology allows the system to operate efficiently even in extreme temperatures as low as -36°C.
What happens if one vacuum tube breaks?
Because no water flows directly into the vacuum tubes, the rest of the system will continue to work normally even if a tube is removed or damaged.
Is hot water available on cloudy or rainy days?
The system can be equipped with an auxiliary electrical heater and an intelligent controller to ensure continuous hot water supply during low-sunlight periods.
Can this be installed on a sloped roof?
Yes, the universal bracket design is suitable for both flat and slope roof installations with excellent wind resistance.
How long will the solar water heater last?
With high-quality stainless steel construction and advanced welding, the system is designed to provide good service for more than 30 years.
