Pentair Eti400 Heat Exchanger Replacement - 475623

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 continuous exposure to water and fluctuating temperatures, the heat exchanger supports steady heat transfer while maintaining system integrity.
