Rheem (Raypak) Premium Pool & Spa Heat Pumps - Inverter Series - 9kw, 13kw, 16kw, 21kw, 28kw

Rheem (Raypak) Premium Inverter Pool & Spa Heat Pumps are one of the most exciting new additions to the Australian pool heating market. There are plenty of newer heat pump brands around, but very few can match Rheem’s national service and support network. That matters when you are buying a major piece of equipment that you expect to last, perform properly, and be backed by real aftersales support.

Rheem is one of Australia’s most recognised names in water heating, and Rheem Thermal is a long-established specialist in pool and spa heating for residential and commercial applications. Their Compact Residential Inverter Series combines modern inverter efficiency, quiet operation, WiFi control, strong build quality, and one of the best warranty structures in the market.

Available sizes include:
9kW, 13kW, 16kW, 21kW, 28kW single-phase, 28kW three-phase, and 35kW three-phase.

Why We Like Rheem Heat Pumps

• Excellent national backup support from a brand Australians already know and trust
• Heating and cooling capability for better year-round pool and spa comfort
• Built-in WiFi control via app connectivity
• Compact footprint for installations where space matters
• Quiet inverter operation with advanced EC fan motor technology
• High temperature settings for spa applications

Warranty Support That Actually Means Something

Not all warranties are equal. Rheem backs the Compact Series with its National Service Network, which is a major advantage over many lesser-known import brands.

• 3 year parts and labour warranty
• 5 years on general parts 
• 10 years on the compressor
• 25 years on the heat exchanger

One standout warranty feature: if the heat exchanger fails within the 3 year comprehensive warranty period, Rheem states they will replace the heater at no cost. That is a serious level of support and one of the strongest warranty offers available in this category.

Key Features

• Twin rotary stepless DC inverter compressor for efficient, precise output control

Australian Compliance and Peace of Mind

These units are independently certified in Australia to comply with Australian Electrical Safety Standards. That is important in a market where some products can look similar on paper but differ significantly in certification, support, and long-term reliability.

• Certified to AS/NZS 60335-1
• Certified to AS/NZS 60335-2-40

Performance and Operating Range

Rheem’s Compact Inverter Series is designed for Australian conditions and offers strong efficiency across a wide operating range.

• Models RPH009-1A, RPH013-1A, RPH016-1A and RPH021-1A operate in ambient air temperatures from -5°C to +43°C
• Models RPH028-1A, RPH028-3A and RPH035-3A operate in ambient air temperatures from -10°C to +43°C

These are inverter heat pumps, so they are designed to modulate output for better efficiency, lower running noise, and more stable temperature control rather than constantly switching fully on and off.
