Panasonic Debuts CO₂ Air‑to‑Water Heat Pump with 6.1 COP

Panasonic introduced a residential air‑to‑water heat pump that uses carbon dioxide as refrigerant. The unit achieves a coefficient of performance (COP) of 6.1, indicating high efficiency. CO₂ refrigerant offers lower global warming potential compared with traditional gases. The heat pump is designed for home heating and hot‑water supply in moderate climates. Panasonic markets the system as part of its push toward greener HVAC solutions. Installation requires compatible indoor and outdoor units and proper piping. Early testers report noticeable reductions in energy bills. The company plans to expand availability across Europe and Asia later this year.
