Pros

  • Digital temperature control with on-board diagnostic feedback
  • Intermittent electronic ignition avoids a continuously burning standing pilot
  • Copper fin-tube heat exchanger and corrosion-resistant cabinet design

Tradeoffs

  • For demanding saltwater or harsh-chemistry pools, buyers may want to compare Raypak's cupronickel versions
