Solar Hot Water Heating System
1. Cut Energy Costs: Solar-powered operation saves up to 70% on electricity bills compared to conventional heaters.
2. Tough & Low-Maintenance: Stainless steel interior prevents scaling; galvanized frame withstands rain, sun, and impacts. No complex upkeep—just set it and forget it.
3. Right Size for You: Compact yet powerful (100L–300L options) for small families, campsites, or guest houses. Portable design for easy relocation as needed.
Product Introduction
1. Copper absorber plates with titanium nitride coating (95% absorption)
2. Low-iron tempered glass (92% transmittance)
3. Polyurethane foam insulation (0.022 W/mK thermal conductivity)
4. The closed-loop design with heat exchanger prevents scaling, while the differential temperature controller automates circulation for maximum efficiency in all seasons
