Product Details

Our pressurized flat plate solar water heater is designed for long-term, stable hot water supply in both residential and commercial applications.

Core Features:

Advanced D-DOS coated solar absorber with up to 93% absorption efficiency.
Compact modular system for faster shipping and installation.
Customizable design: tank volume (150L–300L), enamel/stainless steel material, adjustable mounting angles (0°, 25°, 45°).
Durable pressure tank with enamel or food-grade stainless steel liner for fresh water supply.
Minimal maintenance, long service life, and cost-effective performance.
Simple natural circulation structure ensures steady operation with low failure rate.

Recommended For:

Homes, apartments, offices, schools, and hotels.
Cold-weather regions; performs well even below freezing.

Highlights:

Over 6% higher daily output than vacuum tube systems.
Withstands municipal water pressure and pump-driven systems.
No fragile vacuum tubes—hail-resistant, wind-resistant, and explosion-proof.
Integrated appearance matches modern architectural styles.

How It Works:
Sunlight heats the absorber plate inside the collector. The heat is transferred by circulating fluid to the water tank, which then delivers pressurized hot water from the top outlet.
