150L Stainless steel Non-pressurized solar Water Heater

A 150L Stainless Steel Non-Pressurized Solar Water Heater is a durable and efficient solar water heating system that operates using natural thermosiphon circulation.

Key Features:

• Capacity: 150 liters (ideal for 2-3 people).
• Material: Stainless steel tank and frame for corrosion resistance and longevity.
• Non-Pressurized System: Uses gravity feed instead of high-pressure plumbing, making it simpler and more cost-effective.
• Solar Collector:
  • Uses high-efficiency vacuum tubes (usually borosilicate glass) to absorb solar energy.
  • Tube types: Single-layer or three-target (better absorption).
• Insulation: High-density polyurethane foam (PUF) to retain heat for extended periods.
• Frame: Stainless steel or galvanized aluminum for durability and weather resistance.

How It Works:

1. Water Fills the System: Cold water enters from a supply tank.
2. Sunlight Heats the Tubes: The vacuum tubes absorb sunlight and transfer heat to the water inside.
3. Natural Circulation: Hot water rises to the storage tank, while cold water moves down to be heated.
4. Hot Water Availability: Stored hot water is available for use, even after sunset.

Advantages:

✅ Rust & Corrosion Resistant – Stainless steel construction extends lifespan.
✅ Energy-Saving & Eco-Friendly – Uses solar energy, reducing electricity costs.
✅ Low Maintenance – No moving parts, pumps, or electrical components.
✅ Simple Installation – Can be mounted on rooftops or elevated stands.
✅ Hot Water Storage – Insulated tank retains heat for 24+ hours.
