Optimizing Heat Transfer Efficiency

Heat Pipe Evacuated Tube Collectors are meticulously crafted to achieve the pinnacle of heat transfer efficiency. They boast a design that minimizes heat loss through both A convection and conduction, ensuring that captured solar energy is maximally utilized. By utilizing heat pipes made entirely of copper, these collectors enhance conductivity, further optimizing heat transfer.

Additionally, their innovative design allows for the collection solar energy from multiple angles, granting architects greater freedom in their designs while efficiently harnessing the power of the sun.

Independent Operation and Leak Prevention in the OneWave System

In the OneWave system, each evacuated tube operates independently, ensuring that there is no leakage even if a tube is removed or broken. This closed-loop system means that no water passes through the hot water tank, significantly reducing the risk of leakage.

Enhancing Solar Absorption Tank Longevity

The solar absorber, positioned within the evacuated tube, features an absorber coating consisting of a base layer of aluminium on the exterior of the inner glass tube, followed by aluminium /copper nitride (A/N) material.

Solar Absorptance Of 94%

The vacuum serves as a superior insulator against heat loss, while the aluminium silver coating minimizes heat reflection, resulting in a solar absorptance of 94%.

Efficient Heat Pipe Technology

Heat pipe pressurized solar heater tank operates without an exhaust hole, thus it must withstand the pressure from both the tap water and the heated water. When in use, the hot water is dispensed due to this pressure.

Vacuum tube absorbs solar energy, and a conductive copper pipe transfers this heat into the pressurized solar water heater tank, causing the water inside to become hot. Because there is no water within the heat pipe itself, the entire system is capable of withstanding high pressure.

Solar Water Heater

Solar Heater Essentials

In a solar tube water heater, the Magnesium Rod prevents corrosion inside the tank by attracting corrosive elements, thereby protecting the tank and extending it's lifespan. The Temperature E-sensor monitors the water temperature to ensure efficient heating and prevent overheating, providing safe and consisting hot water. Both components are crucial for maintaining the system's efficiency ang longevity.

Exploring Differences Together

Comparing Evacuated Tube Systems with Flat Plate Heat Systems

Evacuated Tube Collectors vs Flat Plate

OneWave Solar Water Heater Panel Technology vs other brands

Flat Plate Heat Systems

No Such Feature

Do not have display panel and sensor.

Manual Switch

Manual switches need human input, but forgetting to use them can lead to less effective heating or wasted energy.

No Protection

No such features.

Open Loop System

Corrosion on the flat plate's copper riser tubes can result in copper toxicity and blockage, impacting water flow.

Preventing Water Leakage Problems

The copper compression fittings that connect the pipe between the flat plate and the tank may experience due to thermal expansion and contraction in outdoor conditions.

Old System

Older flat plate panel solar water heater systems may face reduced efficiency and reliability from outdated technology, leading to higher maintenance and lower performance in solar energy utilization.

Low Heat Retain

Heat loss occurs because of uninsulated

copper plates and glass in flat plate panel heat collectors.

Evacuated Tube Systems

Temperature Display

Flat panels are commonly used in constructing solar collectors.

Smart Heater Control

Boost efficiency and user convenience by automatically managing water temperature.

Active Protection

magnesium rods maximize anti-corrosion protection, extending the lifespan of water heaters.

Close Loop System

The closed loop solar water heater system efficiently transfer heat using a fluid, improving efficiency and reliability.

Leaking Protection

There is no pipe fitting linking the tank and the evacuated tube, virtually eliminating any possibility of water leakage.

Most Efficient

This Cutting-edge evacuated tube system maximizes heat absorption and minimizes loss, ensuring superior performance and sustainability in solar water heating.

High Heat Retain

The "Thermos Effect" is created by the vacuum between the inner & the outer glass layers, ensuring high heat retention
