SunPower Hybrid Spa Heater transfers FREE heat from your pool to your spa.


  • Extremely energy efficient
  • Safe for the environment
  • Lowest cost spa heating method
  • Does not burn fossil fuels
  • No greenhouse gas emissions
  • Quiet operation – no fan noise


  • Heat output is constant, regardless of air temperature or weather
  • Will heat the spa up to 104°F even when the pool water temperature falls down to 50°F
  • With spillover spa systems, the heat “borrowed” from the pool is returned to the pool when spillover mode is resumed
  • In reverse mode, turn your spa into a “cold plunge” – sports therapists increasingly recommend cold water therapy for rapid muscle recovery after exertion
