Product Components:   

  • Stands up to the toughest conditions 1,800° F flame temperatures and pool water chemistry are all in a day’s work for titanium.     

  • Design elements that boost durability and efficiency. No welds, crimps or joints that reduce corrosion resistance. Tubing is shaped for maximum flow and efficiency.           

  • Industrial chemical processors lean on titanium. When handling concentrated chlorine compounds, industrial processors rely on the corrosion resistance of titanium piping and heat exchangers.

Unmatched Durability And Efficiency:     

  • EASY TO VENT PROPERLY: Fully sealed Category IV direct-air vent does not require large room openings for combustion air.    

  • ULTRA-QUIET OPERATION: Great for you, great for your neighbors.    

  • INSTALL IN LEFT OR RIGHT ORIENTATION: The rotatable front door allows control pad to be rotated 180 degrees, so this heater can be plumbed on the right- or left-hand side. Corrosion-resistant TitanTough Direct-Fire Titanium Heat Exchanger is the strongest heat exchanger ever built - for years of high - quality, trustworthy warmth.

  • 96% thermal efficiency, the highest efficiency ever built in its class. Flexible installation features, including orientation options for gas line connection.

  • Quick access to the Keypad controller.
