How It Works
Solar pool heaters are the most cost-effective use of solar energy. Collector area should be 50-100% of pool surface area. Unglazed collectors work well for pools because they need only modest temperature gains. A solar pool heater typically costs $3,000-6,000 and saves $1,500-3,000 per year compared to gas heating, with a 2-4 year payback.
