Rheem RPH016-1A 16kW Pool Heat Pump Heater – PureSwim (Compact Series)
The Rheem RPH016-1A Compact Series is a high-performance residential pool and spa heat pump built for homeowners who want stronger output for larger pools, faster warm up, or extended swimming seasons. Supplied by PureSwim, this model combines efficient inverter operation with modern controls to keep pool temperatures comfortable while keeping energy use under control.
A twin rotary stepless DC inverter compressor delivers smooth, efficient performance by ramping up when heating demand is high and easing back once the target temperature is reached. The unit is designed for outdoor installation with a durable cabinet suited to harsh conditions, and it includes a single-point condensate drain connection to simplify installation planning.

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.
Find the Minimum Heat Output Required eg. 27KW/Hour
Then you would require a 27kW heater or higher.
