Hot water from the sun—efficient, reliable, and built to last.

Our Solar Water Heaters are available in FPC (Flat Plate Collector) and ETC (Evacuated Tube Collector) models, with tank options to suit your water quality and lifestyle. Choose from pressurized or non-pressurized variants for homes, hotels, institutions, and industries.

Windsun Eco Systems offers high-performance solar water heating solutions designed for maximum heat retention, low maintenance, and long lifespan. We understand that water quality varies across locations—so our inner tank materials are chosen to ensure corrosion resistance and durability:

• GI (Galvanized Iron): For areas with low-to-moderate water hardness.
• HDGI (Heavy Duty Galvanized Iron): Enhanced coating for medium-to-hard water conditions.
• SS304 (Stainless Steel): Premium anti-corrosion choice for coastal or high TDS water, and safe enough for kitchen or drinking water applications as it is near food-grade quality.

System Types

1. FPC – Flat Plate Collector Systems

• Works efficiently in sunny conditions.
• Rugged and long-lasting with minimal maintenance.
• Ideal for areas with moderate climates and low frost risk.

2. ETC – Evacuated Tube Collector Systems

• High heat absorption even in low sunlight.
• Performs well in colder climates and regions with intermittent sun.
• Easy tube replacement and low thermal loss.

Pressure Variants

1. Pressurized Systems

• Compatible with high-pressure pumps and modern bathroom fittings.
• Ideal for multi-storey buildings and high-flow applications.

2. Non-Pressurized Systems

• Gravity-fed and energy efficient.
• Cost-effective option for single-floor or low-pressure setups.

Key Features

• Tank Material Choice: GI, HDGI, or SS304 as per water quality.
