AQUASUN 300L Pressurized Solar Water Heater: High-Performance Eco-Friendly Energy
Upgrade your lifestyle and slash your utility costs with the AQUASUN 300L Pressurized Solar Water Heater. Engineered for modern homes with high-pressure shower systems and multi-story plumbing, this premium 300-liter system utilizes advanced solar thermal technology to provide a consistent, high-velocity stream of hot water.
The AQUASUN pressurized series is designed to withstand the rigors of various water qualities (including borehole water) and harsh climatic conditions. By harnessing the abundant energy of the sun, this system can reduce your monthly water heating bills by up to 75%, offering a sustainable return on investment within just a few years.
The Advantage of a Pressurized System
Unlike standard gravity-fed (non-pressurized) systems that require the tank to be elevated significantly above the taps, the AQUASUN Pressurized System ensures:
-
Strong Water Flow: Hot water is delivered at the same pressure as your cold water supply, making it perfect for rain showers and modern mixer taps.
-
Flexible Installation: Because it is pressurized, the tank can be installed on flat roofs or even lower levels without losing water force.
-
Consistent Temperature: High-pressure tanks are better at maintaining thermal stratification, ensuring you get the hottest water first.

Product Highlights
1. Advanced Vacuum Tube Technology
The AQUASUN 300L utilizes high-grade evacuated vacuum tubes designed to capture maximum solar radiation. These tubes are effective even on cloudy or overcast days, as the vacuum layer acts as a “thermos,” preventing captured heat from escaping back into the atmosphere.
2. Superior Heat Retention
The storage tank is encased in high-density polyurethane insulation. This ensures that water heated during the peak afternoon sun stays hot throughout the night and into the early morning hours, losing only a few degrees of temperature even in cold highlands.
3. Corrosion-Resistant Stainless Steel Tank
Designed for longevity, the inner tank is constructed from high-quality SUS 304 or 316 stainless steel. This material is highly resistant to the scaling and corrosion often caused by “hard” or mineralized borehole water, ensuring your family receives hygienic, rust-free hot water for decades.
4. Smart Backup Integration
For periods of extreme rain or prolonged heavy cloud cover, the AQUASUN system is equipped with an intelligent electric backup heater. This thermostat-controlled element ensures you never run out of hot water, providing a reliable safety net during the coldest months.
5. Safety & Pressure Management
To protect the integrity of your plumbing, the system includes a Pressure and Temperature (P/T) Relief Valve. This safety feature automatically releases excess pressure or steam if the water reaches boiling point, preventing damage to the tank or pipes.
