Fluidra - Titanium Heat Exchanger for Z650iQ MD5 Heat Pump

Fluidra – Titanium Heat Exchanger for Z650iQ MD5 Heat Pump

This is the genuine Fluidra replacement titanium heat exchanger for the Zodiac / Fluidra Z650iQ MD5 swimming pool heat pump. Positioned at the heart of the heat pump, it transfers thermal energy from the refrigerant circuit directly into the pool water, keeping your pool at the desired temperature efficiently and reliably. Replacing a worn or damaged heat exchanger with this OEM part restores the unit’s full heating performance.

Compatibility

This heat exchanger is designed specifically for the Fluidra Zodiac Z650iQ MD5 heat pump — a high-performance, Full Inverter heat pump built for residential swimming pools. Always verify your exact model and assembly variant before ordering to ensure a correct fit; consult your installation manual or a qualified pool technician if in doubt.

Why Genuine Titanium Matters

Titanium is the material of choice for pool heat exchangers because it offers superior corrosion resistance when exposed to treated pool water, including salt-chlorinated systems, while ensuring maximum heat transfer efficiency. As Fluidra notes, the heat exchanger is made of optimised titanium, making it extremely strong and durable. Using a genuine Fluidra part guarantees the same grade of titanium and the same precise dimensions as the original, protecting both your heat pump and your pool water quality.

Installation

The heat exchanger is an internal component of the Z650iQ heat pump and its replacement involves handling refrigerant circuits and hydraulic connections. Installation must be carried out by a qualified pool heating technician or F-Gas certified engineer. Ensure the heat pump is fully isolated — electrically and hydraulically — before beginning any work.
