Fluidra - Titanium Heat Exchanger for Zodiac Z650iQ MD4 Heat Pump

Fluidra – Titanium Heat Exchanger for Zodiac Z650iQ MD4 Heat Pump

This is the genuine Fluidra replacement titanium heat exchanger for the Zodiac Z650iQ MD4 pool heat pump. It is the core water-side component responsible for transferring thermal energy from the refrigerant circuit to the pool water, keeping your heat pump operating at peak efficiency. Titanium construction provides outstanding resistance to chlorinated and saline pool water, ensuring long service life in demanding pool environments.

Compatibility

This heat exchanger is designed specifically for the Zodiac Z650iQ MD4 model — the entry-level variant in the Z650iQ Full Inverter range by Zodiac/Fluidra. The Z650iQ is a high-performance, connected residential pool heat pump featuring Full Inverter technology and four operating modes. Always verify your heat pump’s model and serial number before ordering to ensure correct fitment, as the Z650iQ range includes several variants (MD4 through TD12) that may use different components.

Why Genuine Matters

Using a genuine Fluidra part guarantees exact dimensional and metallurgical compatibility with the original equipment. A correctly fitted heat exchanger maintains the unit’s rated heating efficiency and helps protect your warranty. Third-party alternatives may not meet the pressure ratings or corrosion-resistance standards required for long-term reliable operation in pool water circuits.

Installation

Replacement of the heat exchanger involves accessing the refrigerant and hydraulic circuits of the heat pump, which requires qualified HVAC and pool technician expertise. Refrigerant handling must be carried out by a certified engineer in accordance with applicable F-gas regulations. We recommend engaging an authorised Zodiac/Fluidra service technician to ensure safe, correct installation.
