As Australia advances toward its ambitious goal of achieving net-zero emissions by 2050, the roadmap for Heat Pump Hot Water Systems (HPHWS) represents a pivotal step in transforming the nation’s residential energy landscape. This comprehensive strategy, developed in consultation with industry leaders and funded by the New South Wales and Victorian Governments, outlines a clear pathway for the widespread adoption of HPHWS, a technology poised to revolutionize water heating in Australian homes.

The Urgent Need for Electrification

Hot water systems are a significant contributor to household energy consumption and greenhouse gas emissions in Australia. Currently, domestic hot water accounts for approximately 25% of household energy use and about 20% of residential greenhouse gas emissions. The transition to HPHWS offers a compelling solution, capable of reducing emissions from water heating by up to 80% compared to traditional gas and electric resistive systems.

HPHWS utilize advanced heat pump technology, which is significantly more energy-efficient than conventional systems. This technology extracts heat from the air or ground, even in cold temperatures, to heat water, providing a sustainable alternative that aligns with Australia’s broader electrification and decarbonization goals.

Building Consumer Confidence

One of the primary challenges identified in the roadmap is the need to build consumer confidence in HPHWS. This involves enhancing consumer protections, ensuring the quality of installations, and providing clear, accessible information to consumers. The roadmap emphasizes the importance of setting minimum energy performance standards under the Greenhouse and Energy Minimum Standards (GEMS) Act and developing standardized consumer information materials.

The roadmap also highlights the critical role of regulation in safeguarding consumers. It calls for increased oversight of incentivized installations, mandatory training for installers, and stringent auditing and compliance measures. These steps are crucial to maintaining high-quality standards across the industry, preventing the spread of misleading information, and ensuring that consumers can trust the products and services they receive.

Empowering the Workforce

A skilled and knowledgeable workforce is essential for the successful deployment of HPHWS. The roadmap outlines several key actions to develop this workforce, including revising plumbing apprenticeships to include training on HPHWS and creating a national training course for qualified plumbers. These initiatives aim to ensure that all installers have the necessary skills and knowledge to correctly install and maintain HPHWS, thus supporting the long-term growth of the industry.

Accessibility and Affordability

To ensure the widespread adoption of HPHWS, the roadmap emphasizes the importance of making these systems accessible and affordable for all Australians. This includes providing government incentives and funding for low-income households and implementing a co-payment system to engage consumers more effectively. Additionally, the roadmap advocates for the development of tailored strategies to address the unique challenges of installing HPHWS in strata and commercial buildings, further expanding the reach of this technology.

A Sustainable Future

The roadmap not only focuses on immediate actions but also considers the long-term sustainability of the HPHWS industry. It calls for the development of a national approach to the stewardship of hot water systems at the end of their life cycle, promoting a circular economy. Furthermore, it emphasizes the need for consistent sound level regulations across states and territories, ensuring that the deployment of HPHWS does not negatively impact community well-being.

Industry-Government Partnership

A recurring theme throughout the roadmap is the necessity of a strong partnership between industry and government. The roadmap proposes the formation of a consultative group to oversee the implementation of recommended actions, monitor progress, and create opportunities for collaboration. This partnership is crucial for navigating the complex regulatory landscape, fostering innovation, and ensuring the success of the HPHWS market transformation..

Summary

The roadmap for Heat Pump Hot Water Systems in Australia is a comprehensive strategy designed to guide the country towards a sustainable and energy-efficient future. By focusing on consumer confidence, workforce development, accessibility, sustainability, and industry-government collaboration, this roadmap lays the foundation for HPHWS to become the leading water heating technology in Australia by 2030. As the country works towards its net-zero emissions target, the adoption of HPHWS represents a significant and necessary step in reducing residential greenhouse gas emissions and building a cleaner, greener future for all Australians.

Johnson Controls-Hitachi Air Conditioning continues to lead the way in sustainable cooling and heating technology by unveiling Hitachi’s latest HVAC solutions, reinforcing Hitachi Air Conditioning’s commitment to empowering customers to achieve higher energy efficiency and reduced emissions. The new products were unveiled at Australia’s biggest HVAC&R and building services event, ARBS 2024 by Temperzone Australia Pty Limited, Johnson Controls-Hitachi Air Conditioning’s distributor for Australia and New Zealand.

New technologies have also been introduced into the latest range of Hitachi Air Conditioning products and solutions to improve efficiency and lower indirect emissions in response, helping advance Australia’s Plan to reduce hydrofluorocarbon (HFC) emissions to 15% of the baseline level by 2036 as part of its 2030 greenhouse gas reduction target.

The Hitachi air365 Max Pro system sets industry standards with high efficiency, Japanese design, and engineering. Equipped with SmoothDrive 2.0 technology, it ensures precise temperature control and reduces energy consumption by up to 39% at part load. The unique sigma-shaped (Σ) heat exchanger increases heat transfer efficiency, making it a top choice for those prioritising performance and sustainability.

Mr. Guan Yu, Vice President and General Manager of Johnson Controls-Hitachi Air Conditioning for China, Southeast Asia, and the Pacific, emphasised, “Sustainability has always been our top priority in HVAC product technology and innovation. Providing low-carbon HVAC solutions to our customers in Australia and New Zealand is core to our mission as we remain committed to helping all of our customers embrace decarbonisation and combat climate change.”

The Hitachi SideSmart is the world’s first slim modular VRF unit that adapts to space and capacity needs. It offers a maximum combined cooling capacity of 152 kW, and its slim, modular concept allows larger capacity air conditioning to be achieved almost anywhere, making it one of the most versatile VRF units on the market and the ideal solution for retrofitting.

The Hitachi airCore 700, the flagship light commercial split system range, delivers cooling and heating performance while showcasing a wide capacity range and efficient operation in diverse ambient temperatures, guaranteeing uncompromised comfort. Utilising R32, a low global warming potential (GWP) refrigerant, the airCore 700 split systems offer improved energy efficiency and reduced emissions, allowing for smaller, more compact air conditioning systems that require less refrigerant overall.

Introducing the Hitachi airHome 400 and 600 series, now available for residential use. These sleek air conditioners feature the ViroSenseZ1 air purification filter, which effectively neutralises most viruses and bacteria that pass through the filter. The airHome series includes the FrostWash self-cleaning technology. The airHome 600 series features the AQtiv-Ion for enhanced air quality, an intelligent motion sensor for eco mode, and Wi-Fi enabled with the airCloud Go app.
