UltraSun 15 Tube Solar Water Heater

Efficient Evacuated Tube Technology
With 15 XL Copper Oxide Evacuated Tubes (58×1800×1.8 mm) that have a 3-layer absorber (AL + SS + CU) with 96% absorbance and 97% transmittance, the system can efficiently heat water even on overcast days.

Strong 180 LPD Hot Water Capacity
It is perfect for medium-sized homes, guest residences, and small business applications because it is designed to provide 180 ±10% liters of hot water per day.

SUS-304 Extra-Thick Stainless Steel Tank
The heater’s X-TRA thick SUS-304 stainless steel inner tank and SUS-304 outside tank (Ø470 mm) provide long-term reliability, hygienic water storage, and corrosion resistance.

Excellent 50mm PUF Insulation with High Density
The system reduces heat loss with 50 mm thick PUF insulation (45 kg/m³ density).

Protection System for Magnesium Tanks
The solar water heater’s lifespan is greatly extended by its magnesium protection package, which stops corrosion and scaling inside the tank.

1500W of electric backup heat
Features a 1500-watt electric heating element that produces hot water even when there is not enough sunlight or during rainy seasons.

Large Solar Collector Area of 2.16 m²
The system’s approximately 2.16 m² collector area allows for effective solar energy absorption for quicker water heating.

Robust SUS-202 Support System
Built with components and an extra-strong SUS-202 stainless steel stand at a 30° angle, guaranteeing longevity and stability in inclement weather.

Cutting-Edge Laser and CNC Welding Technology
Produced with the most recent CNC equipment and superior laser welding technology, guaranteeing accuracy, robustness, and long-term performance dependability.

Simple Upkeep with a Flush Cleaning System
The system has an additional flush point within the tank, which facilitates routine cleaning and ensures steady heating effectiveness.

Eco-Friendly & Energy-Efficient Solution
This heater offers an eco-friendly hot water option and drastically lowers power usage by using solar energy rather than electricity.

National Service and International Quality Standards
Constructed in accordance with global quality standards, ULTRASUN’s statewide network of after-sales services in Nepal provides assistance.
