Panasonic launches CO₂ air-to-water heat pump with CoP of 6.1
Panasonic has launched a new CO₂ air-to-water heat pump with a coefficient of performance (CoP) of 6.1, marking a significant efficiency improvement. The system uses CO₂ as a refrigerant and is designed for residential and commercial heating and hot water applications.
Background
- Panasonic has launched a new air-to-water heat pump that uses CO₂ (R-744) as its refrigerant, achieving a coefficient of performance (CoP) of 6.1 — meaning it produces 6.1 units of heat for every unit of electricity it consumes.
- CO₂ heat pumps are more efficient than conventional models in cold climates and use a natural refrigerant with much lower global warming potential than typical synthetic refrigerants (like HFCs). They are especially suited for producing high-temperature hot water (up to 90 °C), which makes them useful for both heating and domestic hot water in homes and commercial buildings.
- This launch matters because heat pumps are a key technology for reducing fossil fuel use in home heating, and CO₂ models represent a leading edge in efficiency and environmental performance. Panasonic is a major Japanese electronics and home appliance manufacturer that competes with brands like Daikin, Mitsubishi Electric, and Vaillant in the heat pump market.
