Now available from Hitachi Cooling & Heating is a new generation airH2O air-to-water heat pump range, featuring two models: airH2O 800 R290 (monobloc and hydrosplit) and airH2O 600 R32 (refrigerant split). This new product range is described as offering high efficiency, superior comfort, and next-level safety, suitable for both refurbishment projects and new residential builds.
The airH2O 800 series runs on R290 refrigerant, a natural refrigerant with a Global Warming Potential (GWP) of just 0.02.
A standout feature of the airH2O range is its advanced noise reduction system. The outdoor units have been meticulously engineered with several enhancements to minimise acoustic impact, including: vibration-absorbing structure to reduce mechanical noise, optimized fan and motor design for smoother, quieter operation; and a dedicated silent mode, for nighttime use or sound-sensitive environments.
The airH2O 800 R290 was engineered with installer and user safety at its core. A sealed design keeps refrigerant outside the living space, eliminating direct contact or handling. Going over the minimum regulatory standard, the heat pump boasts up to 12 integrated safety features, including a real-time leak alarm system .
Built to perform even under extreme conditions, the new airH2O heat pumps deliver: nominal heating capacity guaranteed at -7°C; DHW production up to 55°C at -20°C, and available between -25°C and +43°C; max leaving water temperature of 75°C in heating mode; and up to 60°C at -20°C outdoor temperature with airH2O 800.
