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 250 High-Efficiency Heater’s direct-fire heat exchanger from titanium. It provides long life under extreme conditions.
