Seven SS Star Solar Water Heater 150L Pressurized - SW Series
For discerning homeowners with pressurized water systems, the Seven SS Star 150L Pressurized Solar Water Heater delivers the perfect combination of luxurious hot water performance and exceptional energy efficiency. This premium system represents the pinnacle of solar water heating technology for modern Kenyan residences, offering shower experiences that rival conventional electric systems while dramatically reducing utility bills and environmental impact.
Unlike non-pressurized models, this advanced system works seamlessly with municipal water supplies and pump systems to deliver powerful, consistent water pressure that meets the expectations of contemporary households. The 150-liter capacity serves families of 3-4 people comfortably, providing ample hot water for multiple simultaneous uses”perfect for busy morning routines and evening relaxation.
The engineering excellence of this pressurized system begins with its dual-layer stainless steel tank construction. The inner tank uses food-grade stainless steel that ensures water purity and prevents corrosion, while the outer tank provides structural integrity and additional insulation. Between these layers, high-density polyurethane foam insulation minimizes heat loss”keeping water hot for over 72 hours even during cloudy periods.
The high-efficiency flat plate collectors feature selective coated absorber plates that maximize solar energy capture while minimizing thermal losses. These collectors connect to the storage tank through a closed-loop heat transfer system that uses environmentally friendly antifreeze solution”eliminating freezing risks during cold nights while maintaining optimal efficiency year-round.
What truly distinguishes this pressurized system is its intelligent control features. The digital controller monitors water temperature, solar gain, and usage patterns to optimize performance. It automatically activates the backup electrical element only when necessary, prioritizing free solar energy while guaranteeing hot water availability. The system also includes safety features like temperature and pressure relief valves, anti-scald protection, and leak detection”ensuring worry-free operation.
