Product Introduction:
Flat panel solar geyser is an advanced solar water heating system that uses flat plate collectors to absorb sunlight and heat water efficiently. Designed for homes, hotels, and industries, it replaces traditional electric/gas geysers, offering zero energy costs, eco-friendly operation, and long-term reliability.
Flat panel solar geyser is one of common solar water heater for solar water heating system in home. It provides quality hot water with its new solar energy efficient flat plate design.
This collector includes a selective coating to maximize the solar heat absorption, weather resistant aluminum framing and interior fiberglass insulation for increased efficiency.
