TL;DR
Rheem has announced the launch of the RP17AY, a new variable-speed air-source heat pump designed for residential applications. The system offers high efficiency, universal compatibility, and smart features, marking a significant step in HVAC technology.
Rheem has introduced the RP17AY, a new variable-speed, inverter-driven air-source heat pump designed for residential replacement and new construction, featuring high efficiency and broad compatibility. The product aims to simplify retrofit projects while supporting advanced refrigerants and smart controls.
The RP17AY system measures approximately 991 mm by 908 mm by 908 mm and weighs 125 kg. It offers nominal capacities from 2 to 5 tons, with cooling capacities ranging from 22,000 to 60,000 BTU/h. Operating on a 208/230 V, single-phase power supply, it employs an inverter-driven twin rotary compressor with variable modulation from roughly 35% to 100%, supported by a BLDC condenser fan motor.
According to Rheem, the unit achieves a seasonal energy efficiency ratio 2 (SEER2) of up to 17, an energy efficiency ratio 2 (EER2) of up to 11.7, and a heating seasonal performance factor 2 (HSPF2) of up to 9.5. It uses R-454B refrigerant, a low-GWP A2L refrigerant with safety measures including refrigerant detection and automatic shutdown. The system is compatible with both communicating and legacy controls, facilitating retrofit installations with minimal modifications.
Additional features include integration with Rheem’s EcoNet connected ecosystem, enabling Bluetooth commissioning, onboard diagnostics, and remote monitoring. Sound levels are reported as low as 55 dB under typical conditions, depending on installation specifics.
