This is the genuine Fluidra replacement heat exchanger designed for the Zodiac Z400 iQ pool heat pump in MD8, TD8, MD9, and TD9 configurations. The heat exchanger is the core thermal component of the heat pump, transferring warmth from the refrigerant circuit into your pool water efficiently and reliably. Replacing a worn or damaged heat exchanger with a genuine Fluidra part restores the unit to its original heating performance.<\/p>\n
This heat exchanger is compatible with the Zodiac Z400 iQ heat pump in the following variants: MD8, TD8, MD9, and TD9. The MD8 and MD9 are single-phase models suited to pools of approximately 50\u201380 m\u00b3 and 75\u2013110 m\u00b3 respectively, while the TD8 and TD9 are the three-phase equivalents for the same pool volumes. Always verify your exact model number (found on the unit’s data plate) before ordering to ensure correct fitment.<\/p>\n
Fluidra’s Z400 iQ heat exchangers are manufactured from optimised titanium, delivering exceptional corrosion resistance and long service life \u2014 particularly important in saltwater or coastal pool environments. Using a genuine OEM part guarantees dimensional accuracy, correct refrigerant-side fittings, and full compatibility with the unit’s hydraulic connections, helping you avoid leaks and maintain the heat pump’s rated COP efficiency.<\/p>\n
Replacement of the heat exchanger involves disconnecting both the water-side hydraulic circuit and the refrigerant circuit, which requires appropriate F-Gas certification and qualifications. Professional installation by a qualified pool heating technician or refrigeration engineer is strongly recommended. Ensure the system is fully de-pressurised and isolated before beginning any work.<\/p>","protected":false},"excerpt":{"rendered":"
