Product Components

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

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

3. 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: Rotatable front door allows control pad to be rotated 180 degrees, so this heater can be plumbed on the right- or left-hand side

A Metal That Gets Respect

Titanium is known for excellent corrosion resistance, high strength and light weight. The job of the heat exchanger is to capture the heat from burning gas and transfer it to your pool’s water—the more efficiently, the better. But, the combination of operating heat and pool water chemistry can be tough on exchangers, leading to corrosion and failure. That’s why we made the ETi 400 High-Efficiency Heater’s direct-fire heat exchanger from titanium. It provides long life under extreme conditions.
