AQUASUN 200L Pressurized Solar Water Heater: Superior Pressure & Solar Efficiency
Elevate your home’s energy profile with the AQUASUN 200L Pressurized Solar Water Heater. Specifically engineered for modern residences, luxury apartments, and boutique hotels, this 200-liter system is the gold standard for high-pressure performance. Unlike gravity-fed models, the AQUASUN pressurized series integrates seamlessly with booster pumps and high-velocity plumbing, ensuring your rain showers and multi-point mixers deliver steaming hot water with zero pressure drop.
Designed to serve medium-sized households of 4 to 6 people, this system combines advanced heat pipe technology with rugged materials. Whether you are dealing with the chilly mornings of the highlands or the salty air of coastal regions, the AQUASUN 200L is built to provide reliable, eco-friendly heating that can reduce your monthly electricity bills by up to 75%.
The Heat Pipe Advantage (Pressurized Technology)
The AQUASUN pressurized system utilizes a “Closed Loop” heat pipe design. Inside each vacuum tube is a high-conductivity copper heat pipe.
-
Rapid Heat Transfer: The copper pipes transfer heat to the water tank almost instantly, even with minimal sunlight.
-
No Water in Tubes: Since water does not flow through the tubes themselves, the system is immune to “tube-burst” accidents during freezing nights and won’t leak even if a tube is accidentally broken.
-
Mains Pressure Compatibility: The storage tank is a pressure vessel, meaning it can handle up to 6 Bar (600 kPa) of pressure, delivering hot water as fast as your cold water supply.

Product Highlights
1. High-Performance Vacuum Tubes & Copper Rods
The AQUASUN 200L features 20 premium evacuated tubes. Each tube contains a specialized copper rod that acts as a thermal conductor. This ensures that the water in the tank reaches temperatures of 65°C to 90°C with maximum efficiency, even on overcast or cloudy days.
2. Borehole & Hard Water Resilience
The inner tank is constructed from high-grade SUS 316 stainless steel, which is significantly more resistant to corrosion and pitting than standard steel. This makes the AQUASUN pressurized model the premier choice for properties relying on borehole, salty, or “hard” water sources.
3. Industry-Leading Thermal Insulation
Equipped with a 60mm thick layer of high-density polyurethane insulation, the tank acts as a giant thermos. It can maintain water temperatures for up to 72–80 hours, ensuring you have hot water for your early morning shower even after a rain-filled afternoon.
4. Advanced Safety & Pressure Management
To protect your plumbing and the system itself, every unit comes with a professional Pressure & Temperature (P/T) Relief Valve. This valve automatically releases excess pressure or steam if the water overheats, preventing tank damage and ensuring a safe domestic environment.
5. Year-Round Reliability with Electric Backup
While the sun does 90% of the work, the AQUASUN 200L includes a built-in intelligent electric backup system. During prolonged rainy seasons or periods of exceptionally high demand, the thermostat-controlled 2.0kW element provides a quick boost, ensuring your comfort 365 days a year.
