Installation Notes & Recommendations

The top discharge design allows installation closer to fences or walls compared to side-discharge units.

Ensure sufficient vertical clearance above the unit to allow unrestricted airflow.

Installation should be carried out by a licensed professional to ensure electrical safety and optimal performance.

Maintain recommended water flow rates to protect the heat exchanger and maximise efficiency.
Functionality The Sensaheat TDX 18kW uses advanced inverter technology to regulate compressor speed based on pool demand. This ensures stable water temperatures while reducing power consumption and wear on components.

Its reverse cycle capability allows the unit to both heat and cool pool water, making it suitable for Australia’s changing seasonal conditions. The top discharge airflow design improves installation flexibility and helps keep operating noise to a minimum—perfect for homes with close neighbours.
