Solar heat exchanger 1.2m x 3.05m. The sunkeeper is a swimming pool solar heating system. The existing filter pump sends the cold pool water through the solar panel. The water is heated with the sun’s energy and warm water is returned to the pool. The sunkeeper has everything you need to get you started. For best results follow the recommendations in our sizing chart. It is important to use this sizing chart to ensure your system will be large enough to heat your pool. A properly sized system will raise pool temperatures 10-15 degrees during the season.
