1. Inner tank: Food-grade SUS304-2B or SUS316L (1.2mm-1.5mm thickness)

2. Tank Exterior: High quality Inox 0.4mm

3. Vacuum Tube: Red copper heat pipe, three-target glass tube, aluminium fin

4. Rated Working pressure: 6.0 Bar | Anti-freezing: > -40°C

Working Principle

The pressurized tank bears direct tap water pressure; hot water is pushed out by inlet pressure.
Vacuum tubes absorb solar energy, and conductive copper heat pipes transfer heat into the tank.
No water flows inside the heat pipes, ensuring the system remains operational even if a tube is damaged.
High efficiency and rapid warming even in cold climates.

Competitive Advantages

Adopts high-performance metal heat pipes (copper) for maximum conduction.
System pressure rated up to 0.6Mpa, allowing direct connection to tap water.
Inner tank design has passed 100,000 fatigue tests without damage.
Dual-purpose brackets suitable for both flat and inclined roof installations.
Maintains constant water temperature and avoids water level controller malfunctions.

Packing & Delivery

Package Details: For full container loading (FCL), we use standard seaworthy cartons. For less than container loading (LCL), we utilize a combination of plywood crates and seaworthy cartons for maximum protection.

Frequently Asked Questions

Can this solar water heater work in freezing temperatures?

Yes, the system is designed with an anti-freezing capability down to -40°C, making it suitable for cold climates year-round.

What happens if one of the vacuum tubes breaks?

Because the system uses heat pipes and there is no water inside the tubes, the rest of the system will continue to work normally even if one tube is damaged.

Is it compatible with high-pressure tap water?

Absolutely. This is a pressurized type solar water heater that can handle working pressures up to 0.6 MPa (6.0 Bar) and connects directly to your tap water line.

What is the lifespan and warranty of the product?

We provide a 5-year quality warranty. With high-quality stainless steel (SUS304/316L) and professional manufacturing, the system is built for long-term durability.

Can the bracket be installed on a flat roof?

Yes, we provide dual-purpose brackets that are scientifically designed for both flat and inclined roof installations at angles between 25° and 51°.

Does it require an intelligent controller?

While the basic system works automatically, optional devices like intelligent controllers, electric heaters, and magnesium bars can be added for enhanced convenience and protection.
