Description
Hydrotherm Fusion/X8 Heat Pump Hot Water System
Australia’s most advanced hot water system. The Hydrotherm Fusion/X8 uses R290 natural refrigerant, a non-sacrificial impressed current anode, and GMCC Toshiba compressor to cut hot water running costs by 70%, with full Tuya Wi-Fi control and a 5-year replacement warranty covering tank, electronics, and refrigeration.

Advanced Technology. Zero Maintenance Anode.
The Hydrotherm Fusion/X8 stands apart with a non-sacrificial impressed current anode, protection that never needs replacing, in both soft and hard water conditions. Combined with a GMCC Toshiba compressor, microchannel heat exchanger, and R290 natural refrigerant, it’s the most comprehensively engineered system in its class.
70% Less Energy
The Fusion/X8 reduces hot water energy consumption by 70% compared to conventional electric resistance systems. Registered as a Clean Energy product with an annual carbon reduction rating of 3 tonnes.
Non-Sacrificial Impressed Current Anode
Unlike standard magnesium anodes that need periodic replacement, the impressed current anode provides continuous, maintenance-free tank protection, effective in both soft and hard water areas. Never needs replacing.
Solar Battery for Your Home
Set built-in timers to run during peak solar output, typically 10am to 4pm. The insulated 268L tank stores that heat energy for 24-hour use, making the Fusion/X8 an effective thermal battery for your rooftop solar PV.
Tuya Wi-Fi Control
Connect via the Tuya smart-home app to monitor and control your hot water from anywhere. Adjust heating times and temperatures remotely, set intelligent schedules, and get visibility over your system’s operation from your phone or tablet.
