GoKawiilHitachi's new EcoCute CO2 water heaters add solar tariff-shifting controls for 2026 launch
Hitachi Global Life Solutions has unveiled a Y-series of EcoCute CO2 heat pump water heaters for Japan, with sales beginning progressively from November 2026. The flagship BHP-FV37YD and BHP-FV46YD models offer mains-pressure hot water in 370-liter and 460-liter capacities for three-to-five and four-to-six person households respectively, though full efficiency specs remain undisclosed. The key update is broader compatibility with electricity tariffs that reward daytime water heating, selectable directly via the unit's remote controller.
