en.Wedoany.com Reported - Panasonic has introduced an air-to-water heat pump system using natural refrigerant CO₂ (R744) for the Australian residential market. The product is available in two outdoor unit sizes, 4.0 kW and 6.0 kW, paired with eight storage tank options ranging from 250 to 400 liters (enamel or stainless steel), offering a total of 16 configuration choices. This CO₂ heat pump replaces traditional synthetic refrigerants with a natural alternative, maintaining high efficiency even in low-temperature environments.

The CO₂ heat pump system has a maximum capacity of 6.0 kW and a claimed coefficient of performance (COP) of 6.1, meaning it generates 6.1 units of heat energy for every unit of electricity consumed. It can produce hot water at 59°C even at an ambient temperature of -10°C without requiring auxiliary electric heating. The system can be integrated with household photovoltaic systems, and users can flexibly set heating schedules and temperatures via a Wi-Fi controller and the Panasonic Comfort Cloud app. This CO₂ heat pump operates at a noise level of just 37 dB(A) and comes with a 10-year warranty on parts and labor.

Joe De Bella, Marketing and Engineering Manager of Panasonic Australia's HVAC Solutions Group, stated: "Heat pump solutions are gaining popularity in the Australian market as a cost-effective alternative to natural gas and electric water heating, enabling energy savings."

The product qualifies for Australia's Small-scale Renewable Energy Scheme (SRES) and may also be eligible for additional state-level subsidies. Panasonic has held a leading position in the Japanese heat pump market for over 25 years, with cumulative installations exceeding 2 million units.
