Always Enough Hot Water for Large Families
Panasonic’s split-type system uses stratified heating, warming water from the top for quick access even during reheating. This design ensures a continuous supply of hot water—always enough for large families—so you can enjoy more showers without worrying about running out.
Hot Water, Faster and More Efficient
Panasonic’s CO₂ heat pump hot water system heats 200L to 40°C in less than half the time compared to the integrated systems, while using 30% less energy. You can get quick access to hot water when you need it, plus outstanding energy savings for your home and the environment.
Assumption:
・In mid-season, Ambient 19.0℃ / Water 17.0℃ / 200L Tank / Target Outlet 40℃, under heat pump-only operation.
・Comparison against an integrated heat pump system with a rated heating capacity of 3.6 kW (ambient temperature: 32.6°C; inlet water temperature: 21.1°C).
