Description
200L High Pressure Solar Water Heater Overview
-
Mains Pressure Comfort: Delivers hot water at full household mains pressure (0.6MPa / 6 bar) for powerful showers and efficient appliance feeding .
-
Generous 200L Capacity: Ideal for medium to large families (4-6 persons), ensuring ample hot water for simultaneous usage .
-
Advanced Heat Pipe Technology: Utilizes copper heat pipes for rapid heat transfer, maintaining high efficiency even in cold conditions down to -35°C .
-
Indirect Heating Design: Water never enters the glass tubes—only heat is transferred via copper condensers, eliminating leakage risks .
-
Superior Insulation: High-density polyurethane foam (50-55mm) ensures minimal overnight temperature drop .
-
Durable Construction: Built with food-grade inner tank material and a powder-coated outer frame for long-term reliability .

How It Works
The 200L high pressure system delivers reliable hot water through a simple, effective process:
-
Solar Collection: Evacuated glass tubes absorb solar radiation, converting sunlight into heat energy through high-efficiency selective coating .
-
Heat Transfer: Inside each tube, a sealed copper heat pipe contains a special fluid that vaporizes at low temperatures. The vapor rapidly rises to the condenser tip at the top of the tube .
-
Water Heating: The hot condenser tip transfers heat to the water inside the pressurized tank through a heat exchanger jacket. Water never enters the tubes themselves .
-
Pressurized Delivery: Because the tank is sealed and connected to mains pressure, hot water flows forcefully to your taps, showers, and appliances on demand—no header tank or gravity feed required .
Why Choose a High Pressure System?
Many homeowners in our area grew up with low-pressure “gravity” solar systems that produce disappointing shower pressure. The 200L high pressure system solves this completely. By connecting directly to your mains supply, you enjoy:
-
Strong, consistent water flow ideal for modern mixer showers
-
Compatibility with instantaneous gas heaters as backup
-
Ability to feed multiple bathrooms simultaneously
-
No noisy pump requirements—the mains does the work
Local Installation Considerations
For homes in our region, proper installation ensures optimal year-round performance. Our systems are configured to handle local water conditions and typical household layouts. Key considerations include:
-
Roof Orientation: Panels should face north (in the Southern Hemisphere) for maximum sun exposure throughout the year .
-
Roof Strength: Ensure your roof structure can support approximately 300kg when the tank is full .
-
Plumbing Integration: Connection to existing geyser piping is straightforward—our installers can typically complete the job within one day .
-
Municipal Water Quality: We recommend installing a simple sediment filter before the solar inlet to protect the system and maintain efficiency over time .
Installation Summary
-
Mounting: Securely fix the frame on a north-facing roof or stand. All feet must contact the surface evenly on load-bearing structures.
-
Tank Placement: Position the tank level on the frame before tube installation.
-
Tube Installation: Insert heat pipe tubes gently into tank ports with a twisting motion. Secure bottoms in the frame holder.
-
Plumbing: Connect to mains cold water supply. Install pressure relief valve and temperature relief valve as mandatory safety components .
-
Final Check: Fill system before sun exposure to prevent tube damage. Check all connections for leaks.
200L High Pressure Solar Water Heater Maintenance
-
Clean glass tubes every 6-12 months to maintain peak efficiency .
-
Annually test pressure relief valve operation (discharge water will be extremely hot) .
-
Inspect tubes periodically for condensation inside glass (indicates broken vacuum requiring replacement) .
