Key Features:

1. Tank Specifications:

• Capacity: 250 liters (ideal for 5-8 people).
• Inner Tank Material: High-quality food-grade stainless steel (SUS304 or SUS316) for exceptional durability and hygiene.
• Outer Tank Material: Stainless steel (with a polished or matte finish) for enhanced durability and aesthetic appeal.
• Insulation: 40-50mm thick polyurethane foam (PUF) for excellent heat retention, ensuring that water stays hot for extended periods.

2. Solar Collector System:

• Type: Typically features flat plate collectors or vacuum tube collectors for efficient solar energy absorption.
• Collector Area: Designed to maximize sunlight exposure, ensuring optimal heating efficiency.
• Heat Transfer Fluid: Utilizes a pressurized system that circulates water or heat transfer fluid, allowing for faster heating and consistent hot water availability.

3. Frame and Structure:

• Frame Material: Galvanized steel or aluminum for stability and resistance to corrosion.
• Installation Type: Designed for rooftop installation to optimize solar exposure.

How It Works:

1. Water Supply: Cold water enters from the main supply line into the pressurized tank.
2. Solar Absorption: The solar collector absorbs sunlight and heats the water or heat transfer fluid.
3. Heat Transfer: The heated fluid transfers heat to the water inside the storage tank.
4. Hot Water Availability: The pressurized system ensures a consistent hot water supply, providing hot water on demand.
