Paramount on Parkes in Harris Park required a modern hot water solution to improve efficiency, increase storage capacity and support the demands of a mixed-use development.
Rinnai delivered a Demand Duo system with six 315L storage tanks, providing reliable hot water performance, reduced running costs and improved sustainability outcomes.
Background
Completed in November 2024, Paramount on Parkes is a mixed-use development in Harris Park, NSW, comprising 89 residential apartments and six levels of commercial space. To support the hot water demands of both residents and commercial occupants, the development required a high-capacity and energy-efficient hot water solution capable of delivering long-term reliability and performance.
Challenge
A key challenge of the project was gaining access to the facility's services area to remove existing equipment and install the new system. The project required careful planning and coordination to ensure the replacement could be completed efficiently while accommodating site access constraints.
The upgraded system also needed to deliver increased hot water storage capacity, improved energy efficiency and enhanced reliability to support the demands of the development.

Solution
Rinnai supplied and installed a Demand Duo commercial hot water system incorporating six 315L storage tanks.
The new configuration was designed to provide greater hot water storage capacity while improving overall system efficiency. By replacing the previous equipment with a modern Demand Duo solution, the development gained a reliable and scalable hot water system capable of meeting the needs of both residential and commercial occupants.
Outcome
Rinnai's Demand Duo solution with six 315L storage tanks increased hot water capacity, improved energy efficiency, reduced operating costs and delivered reliable performance for this mixed-use development.
The increased storage capacity and modern system design provide dependable hot water delivery for residents and commercial tenants while helping reduce ongoing operating costs and supporting long-term building performance.
By implementing a new Demand Duo hot water solution, Rinnai helped Paramount on Parkes achieve greater efficiency, reliability and sustainability.
