Description
350L Low Pressure Solar Water Heater Overview
-
High Capacity: Provides ample hot water for large families (10+ members), guesthouses, lodges, or small businesses like salons and restaurants.
-
Low Pressure System: Engineered for gravity-fed applications (max 0.05Mpa), making it ideal for areas with unstable mains pressure or where header tanks are used.
-
Efficient Solar Collection: Features advanced evacuated glass tubes with high absorption rates to ensure hot water even during cloudy conditions.
-
Excellent Heat Retention: High-density polyurethane foam insulation minimizes heat loss overnight.
-
Durable Build: Constructed with a robust inner tank and a powder-coated frame for long-term resistance to weather and corrosion.

350L Low Pressure Solar Water Heater Installation Summary
-
Mounting: Secure the frame on a roof or stand facing the equator (North in the Southern Hemisphere, South in the Northern Hemisphere). Ensure the surface can support the full weight (approx. 450kg).
-
Tank Placement: Position the tank level on the frame.
-
Tube Installation: Lubricate tube ends and insert gently into the tank seals with a twisting motion. Secure the bottom into the frame holder.
-
Plumbing: Connect to a header tank. Crucial: Never connect directly to high-pressure mains. Install vacuum breakers and a pressure control valve.
-
Final Check: Fill with water before sun exposure to prevent tube damage. Check all connections for leaks.
Maintenance
-
Clean glass tubes every 6-12 months to remove dust.
-
Annually check pressure relief valves (discharge water is hot).
-
Inspect for condensation inside tubes (indicating a broken vacuum).
