3.2 JAPAN

Among residential ATW HPWHs, Eco Cute, which plays a central role in Japan, is a high-efficiency water heater that adopts CO2 and uses heat pump technology to produce hot water.
According to JRAIA statistics, the Japanese Eco Cute market in 2023 amounted to 631,616 units, down 9.2% year on year. Although this indicates a decrease, it is likely due to the significant growth rate achieved in 2022.
