Thermax solar pool heating panels work effectively in cooler weather conditions because of their unique design, materials, and engineering, optimized specifically for cold and windy climates. Originally manufactured for the cooler German climate, these solar pool heating panels are designed to deliver exceptional heating performance during the shoulder seasons of spring and autumn. During this period, traditional solar pool heaters are unable to work. What factors can contribute to the superior cold-weather effectiveness of Thermax panels: Design for Cooler Climates Traditional PVC tubular or rubber mat solar collectors are spherical and fin-like in shape, which work adequately in hot weather. These systems cause significant efficiency drops in cooler, windy shoulder months. In contrast, Thermax panels have a flat-face, large open-bore collector design with minimal air gaps and hot spots. These panels create turbulent water mixing that closely approaches the maximum the...
