Hitachi Cooling & Heating is proud to announce the launch of its new generation airH2O air-to-water heat pump range, featuring two models: airH2O 800 R290 (monobloc and hydrosplit) and airH2O 600 R32 (refrigerant split).
Fully designed and manufactured in Europe to meet the evolving demands of sustainable, low-carbon heating across the region, this new product range offers high efficiency, superior comfort, and next-level safety – suitable for both refurbishment projects and new residential builds.
R290: the sustainable choice
R290 (propane) is a natural refrigerant with a Global Warming Potential (GWP) of just 0,02 in last GIEC report
The newly introduced airH2O 800 series, running on the eco-friendly R290 refrigerant, marks a major advancement in Hitachi Cooling & Heating’s commitment to environmental responsibility.
R290 (propane) is a natural refrigerant with a Global Warming Potential (GWP) of just 0,02 in last GIEC report, making it one of the most climate-friendly options currently available. In line with evolving EU F-Gas regulations, this choice reduces environmental impact while maintaining exceptional performance.
“This is not just a new product – it’s the beginning of a new era in our air-to-water heat pump portfolio,” said David Bioche, EMEA Marketing & Product Management Director Hitachi Cooling & Heating.
silent heat pumps
With a sleek, modern design, these units are crafted to blend effortlessly into any environment, while providing an ultimate comfort for end-users. A standout feature of the airH2O range is its advanced noise reduction system.
The outdoor units have been meticulously engineered with several enhancements to minimize acoustic impact, including:
- A vibration-absorbing structure to reduce mechanical noise,
- An optimized fan and motor design for smoother, quieter operation,
- And a dedicated silent mode, ideal for nighttime use or sound-sensitive environments.
These elements work together to offer discreet comfort, barely noticeable yet always effective. For instance, the airH2O 600 (8.5 kW) model boasts a remarkably low acoustic level of just 41 dB(A) at 1m, – making it an ideal solution for installations where noise control is a priority.
Safety first
The airH2O 800 R290 was engineered with installer and user safety at its core
The airH2O 800 R290 was engineered with installer and user safety at its core. Its sealed design keeps refrigerant outside the living space, eliminating direct contact or handling.
Going far over the minimum regulatory standard, the heat pump boasts up to 12 integrated safety features – including a real-time leak alarm system connected to the mobile app – make it the safest R290 heat pump on the market.
All configuration and commissioning operations are managed from the indoor controller, or even through the smartphone via an exclusive NFC functionality, eliminating the need to open the unit.
Additional features
Additional features for installer convenience include:
- Integrated pump and hydraulic separator/buffer tank (in indoor units)
- Three ergonomic transport handles for easy handling
- Remote via its Wi-Fi gateway as a standard and its app CSNET Home & Home PRO
“Safety is not an option in the Hitachi Cooling & Heating range – it’s a standard”, added David Bioche.
Smart connectivity for modern living
Designed to enhance convenience and efficiency, the airH2O range is equipped with cutting-edge smart features that simplify everyday life:
- NFC technology ensures quick setup and hassle-free commissioning, making installation and maintenance more efficient than ever (create / copy / paste / duplicate a setting directly with the smartphone).
- Built-in Wi-Fi enables seamless remote control, allowing users to monitor and adjust their system from anywhere.
- CSNET Home App, designed for both professionals and homeowners, provides intuitive access to settings, performance insights, and troubleshooting support.
- Next-generation colour LCD controller, recognized with the prestigious European Product Design Award, now comes in an elegant black finish (in option, not standard), blending innovation with sleek aesthetics.
High performances in demanding conditions
Built to perform even under extreme conditions, the new airH2O heat pumps deliver outstanding heating performance and domestic hot water production:
- Nominal heating capacity guaranteed at -7°C
- Domestic hot water (DHW) production up to 55°C at -20°C, and available between -25°C and +43°C
- Maximum leaving water temperature of 75°C in heating mode and up to 60°C at -20°C outdoor temperature with airH2O 800
- New 8.0 / 8.5 kW models now available in both series
Thanks to advanced technologies like CONSTANT POWER and CONSTANT WATER, the system maintains a stable output water temperature and capacity even in the most demanding conditions, ensuring uncompromised comfort.
