The Block Australia 2025
Innovation at the Heart of The Block 2025: Hitachi Cools and Heats Homes of Daylesford
As The Block Australia 2025 unfolded in the scenic town of Daylesford, viewers witnessed not only the creation of five architecturally stunning, carbon-neutral homes — but also the integration of innovative HVAC technology.
Behind the scenes, each home has been fitted with a premium climate control solution featuring Hitachi SideSmart VRF systems connected to a combination of Silent Iconic four-way cassettes and low-profile ducted indoor units, and Hitachi airCore 700 high static ducted systems with premium zone controllers. Together, these technologies deliver exceptional comfort control, energy efficiency and design flexibility — exactly what this ambitious season demands.
Side Smart VRF: Powering Efficiency in Every Room
Supporting the build-from-scratch home designs, the Hitachi SideSmart VRF system provides the intelligent, adaptable backbone of two home’s heating and cooling. With its compact footprint and advanced inverter technology, Side Smart VRF allows contestants to maximise space planning without compromising on performance. Incorporating Hitachi’s AirCloud Pro Gateway controller enabled full smartdevide WiFi control of each VRF system, form anywhere. These systems continually optimises energy use, making it an ideal fit for The Block’s sustainability-focused season.
Silent Iconic: Style Meets Quiet Performance
The contestants were particularly impressed with the Hitachi Silent Iconic cassette, an exceptional and award-winning air solution that marries both form and function. Its distinctive design elevates the aesthetic appeal and makes it ideal for the show’s pavilion-style homes where visual harmony matter.
airCore 700: Uncompromised Performance and Efficiency
Hitachi airCore 700 High Static Ducted systems were chosen due to their outstanding cooling and heating performance and efficient operation in diverse ambient temperatures up to 52C, while guaranteeing uncompromised comfort.
Premium Zone Control: Personalised Comfort, Room by Room
To give each family ultimate control over their environment each airCore 700 ducted system was paired with the Premium Zone Controller, allowing homeowners to tailor the temperature in individual spaces throughout the day. The Premium Zone Controller allows for connection of up to 8 zones with individual temperature control.
Incorporating airCloud Go WiFi adaptor kit enabled full smartphone control of each ducted system from anywhere.
Whether it’s cooling a sunny north-facing living room or warming the master suite on a crisp Daylesford morning, the zoning system gives unmatched flexibility — delivering comfort exactly where and when it’s needed.
