Rheem RPH009-1A 9kW Pool Heat Pump Heater – PureSwim (Compact Series)
The Rheem RPH009-1A Compact Series Pool Heat Pump is a high-performance residential pool and spa heater designed to deliver consistent and comfortable water temperatures throughout the year. Supplied by PureSwim, this model is ideal for homeowners looking for an energy-efficient alternative to conventional electric or gas pool heating.
Compact in size yet big on performance, the RPH009-1A provides up to 8.6kW of heating output and operates efficiently across a wide range of Australian climates. Its twin rotary stepless DC inverter compressor allows the system to run smoothly and efficiently by adjusting power output as required, maintaining stable temperatures while keeping energy use under control.
The unit features a durable ABS and aluminium alloy cabinet, offering excellent resistance to corrosion and outdoor exposure. A single-point condensate drain simplifies installation, while the compact footprint allows for easy placement in tight equipment areas without compromising airflow or performance.

Do This First!
Which Size Pool Heater Do I Need?
Selecting the correct pool heater is the essential first step before exploring the range of pool heat pumps available. The ideal unit depends on several factors. Consider if you use a pool cover, your local climate, the season during which you plan to heat your pool and environmental conditions such as wind or shade. For instance, a small, well covered pool in a mild region may only require a 9kW unit. In contrast, a larger pool or one exposed to windy, cooler conditions might benefit from a 28kW heater for consistent performance throughout the year. To choose the perfect unit for your pool’s needs, try the Waterco pool heater calculator, to determine the optimal heater size and maximise energy efficiency and budget savings.
