"Efficient, Affordable Luxury"
The Onga Pantera 20kW Inverter Heat Pump by Pentair offers efficient and affordable luxury for your swimming pool, extending your swimming season from summer to spring, autumn, and even winter.
Equipped with full-inverter technology, the new Pantera inverter heat pump delivers powerful, yet quiet, performance, thanks to the combination of a variable speed compressor and fan motor.
Utilizing a fraction of the energy required by traditional gas or electric heaters, this heat pump can generate up to ten times the amount of heat per dollar of electricity used. Featuring a powerful and efficient inverter compressor, an intuitive LED touchscreen, and a robust UV-resistant thermoplastic case, the Pantera is designed to deliver reliable and quiet operation under Australian conditions.
Benefits:
- Quiet - 'Silent Mode' slows down the variable speed DC fan, reducing noise for whisper quiet operation.
- Powerful & Efficient - Inverter compressor gives you the power to heat up quick and efficiency to maintain.
- Easy to Use - Intuitive LED touchscreen makes set-up and operation clear and simple.
- Tough - UV resistant, rust-proof thermoplastic case designed for Australian conditions.

Features:
- Pentair heat pumps transfer heat from the air into the pool using only a fraction of the energy required to heat the pool directly.
- The Pantera heat pump offers excellent efficiency with COP (coefficient of performance) ratings in excess of standard heat pumps.
- The Onga Pantera heat pumps feature variable speed compressors and fan motors (full inverter). These operate at reduced speed when full power is not required, cutting electricity costs and noise.
- Pentair heat pumps use the EPA-recognized, environmentally safe, non-ozone depleting R32 refrigerant.
- 100% titanium heat exchanger assures corrosion- free performance for extra long life and value.
- LED touchscreen is easy to set up and provides a clear display.
- Self-diagnostic software continuously monitors system for peak performance
- Automatic defrost feature senses refrigerant temperature and helps prevent the Pantera heat pump from freezing, allowing the unit to operate effectively at lower temperatures.
- Easy barrel union plumbing connections.
