TL;DR
Rheem has announced the launch of the RP17AY, a variable-speed air-source heat pump designed for residential use. It features high efficiency, universal compatibility for retrofit projects, and smart connectivity. The product aims to simplify installation and improve energy performance.
Rheem has introduced the RP17AY, a variable-speed, inverter-driven air-source heat pump designed for residential use, with a focus on universal retrofit compatibility and enhanced efficiency. The product aims to streamline installation processes and integrate with existing HVAC systems, marking a significant development in residential heat pump technology.
The RP17AY system measures 991 mm x 908 mm x 908 mm and weighs 125 kg. It offers nominal cooling capacities from 2 to 5 tons, with the largest model delivering 60,000 BTU/h, and operates on a 208/230 V, single-phase, 60 Hz power supply. The system features an inverter-driven twin rotary compressor with variable-speed modulation from roughly 35% to 100%, supported by a brushless DC condenser fan motor. It achieves a seasonal energy efficiency ratio (SEER2) of up to 17, an energy efficiency ratio (EER2) of up to 11.7, and a heating seasonal performance factor (HSPF2) of up to 9.5, according to Rheem.
The unit uses R-454B refrigerant, a low-GWP A2L refrigerant classified as mildly flammable, and incorporates safety features such as refrigerant detection and automatic shutdown. It is compatible with both communicating and legacy 24V non-communicating controls, allowing it to be used with a wide range of indoor coils and air handlers, reducing retrofit complexity. Additionally, it supports Rheem’s EcoNet connected ecosystem, offering Bluetooth-enabled commissioning, onboard diagnostics, and remote monitoring capabilities, aimed at simplifying installation and ongoing system management.
Implications for Residential HVAC Retrofit and Efficiency
The launch of the RP17AY signifies a step forward in residential HVAC technology by combining high efficiency with broad system compatibility, especially for retrofit projects. Its smart features and use of low-GWP refrigerant align with industry trends toward sustainability and ease of installation. This development could influence market standards and contractor choices, potentially accelerating the adoption of inverter-driven heat pumps in residential settings.
