components, leak detection with app alerts, and exterior commissioning access. Output temperatures support boiler replacement: up to 75°C hot water from the LH2 800 Plus and 65°C from the LH2 600. Production has begun at the Barcelona facility, with initial shipments in July and wider distribution planned for September.


Bioche noted that the airH2O platform builds on earlier


He said that the aim was to create environments that support human health and comfort, linking air quality and performance to broader wellness goals. Previous developments at the site include the VRF platform and the Triple C system, which provides heating, cooling, and sanitary hot water. The new airH2O heat pump builds on  digital connectivity. David Bioche, Director of Product Management,


introduced the airH2O range, which includes two models developed to meet European climate and regulatory standards:  LH2 800 Plus: A monobloc system using R290 (propane) refrigerant


 LH2 600: A split system using R32 refrigerant


The models support a range of heating outputs from 4kW  using a standard outdoor unit. Built-in components such as

products such as the Aquavie series (2005), S-series, and Yutaki models.

This includes updated compressors, adaptive software, and improved heat exchangers. Use of R290 refrigerant also allows stable performance at lower outdoor temperatures. The airH2O range will be available in all major European markets. Although split systems currently account for about 80% of production, demand for monobloc models is expected to rise, especially in Northern and Central Europe and parts of Southern Europe, as regulations shift and propane-based systems become more widely adopted.


Into a new future The launch also highlighted Hitachi’s global footprint, including training centres, distributor partnerships, and a multinational workforce. The company reinvests approximately 8% of its annual revenue in research and development to advance HVAC systems in both residential and commercial markets.


The launch took place shortly before a major organisational change. Bosch is expected to complete its acquisition of Johnson Controls’ residential and light commercial HVAC business, including Hitachi Heating & Cooling, by 1 August. The acquisition, initially announced in July 2024, is pending regulatory approval at the time of writing.


Hitachi described the deal as a long-term investment and


expects continuity in its technical roadmap and European operations.
