Description
Pentair 475623 TitanTough Heat Exchanger for ETI 400 Heater
A heat exchanger is the core component that transfers thermal energy into your water, delivering efficient, controlled heating without direct contact between the heat source and the water itself. Designed for integration with heating systems, this unit circulates water through a series of thermally conductive passages. The result is consistent temperature management and reduced energy waste. Built to withstand continous exposure to water and fluctuating temperatures, the heat exchanger supports steady heat transfer while maintaining system integrity.
