Split Presurized Solar Water Heater
Key Advantages:
1. Year-Round Performance: Vacuum tubes absorb solar energy even in cloudy weather or sub-zero temperatures (-25°C to -30°C).
2. High-Pressure Output: Integrates seamlessly with existing plumbing for strong shower flow.
3. Anti-Freeze Technology: Heat pipes prevent freezing without glycol additives.
4. Space-Saving & Aesthetic: Compact roof footprint; storage tank installed indoors/out of sight.
5. Low Maintenance: Self-cleaning tubes & corrosion-resistant materials.
6. Energy Savings: Reduce electricity/gas bills by 60–80%.
Product Overview:
Vacuum Tube Split Pressurized Solar Water Heater: Reliable & Efficient Hot Water Solution:
Our Vacuum Tube Split Pressurized Solar Water Heater harnesses solar energy to deliver high-pressure, continuous hot water for residential, commercial, and industrial use. Unlike traditional systems, its innovative split design separates the solar collector (rooftop-mounted) from the pressurized storage tank (ground/indoor installation), offering unmatched flexibility, efficiency, and frost resistance.
