UPGRADED DESIGN: Rings inflate quickly & lay flat every time; Heaters capture solar energy to heat pool during the day and insulate it at night; Use multiple heaters to cover at least 80% of pool surface for best effectiveness
HEATING SAVINGS: Includes 3 inflatable heaters; Works well with existing gas and electric heaters for faster heating
SIMPLE DESIGN: These heaters are completely flat and have a solid blue color for a modern look in any backyard pool
RECOMMENDED SIZE: Each one measures 5 ft x 5 ft and covers 25 square feet of pool surface; To estimate the number of rings needed for 80% coverage, divide pool's surface area by 30
INCREASED COVERAGE: The thick outer perimeter of these heaters reduce overlap and extend coverage over pool surface area.
