The Onga UltraTemp VXi 13kW vertical inverter pool heat pump is engineered for residential swimming pools and spa environments requiring efficient year-round water temperature management. Its vertical discharge configuration eliminates horizontal airflow clearance restrictions, making the unit suitable for installations where side access space is limited.
The system operates using a Panasonic inverter compressor together with intelligent variable-speed performance control to balance heating capacity and energy efficiency automatically. Under Ambient 27°C / Water 26°C test conditions, the UltraTemp VXi 13kW achieves heating capacity performance from 3.5 kW to 13.5 kW together with COP performance ranging from 13.5 to 6.5 depending on operational demand and environmental conditions.
The integrated Wi-Fi module allows remote monitoring and temperature adjustment through the Handy-Heat mobile application, while the full-colour LCD touchscreen provides simplified local system configuration. The unit supports both heating and cooling functionality together with automatic defrost operation for stable seasonal performance across changing climate conditions.
Constructed with colour-coded barrel union plumbing connections and a titanium threaded heat exchanger, the UltraTemp VXi 13kW is designed for corrosion resistance and long-term pool water compatibility. The heat pump operates on 240v single phase power with maximum current draw of 11.3A and recommended water flow performance of 108 L/Min.
