Maestri Towers in Sydney required a modern replacement for its ageing boiler system that could improve efficiency, increase capacity and maintain reliable hot water supply for residents.
Rinnai delivered a new solution featuring HD28i Heavy Duty Continuous Flow Water units and a Demand Duo system, providing improved performance, lower running costs and greater system redundancy with minimal disruption to the occupied building.
Background
Maestri Towers, a residential apartment complex in Sydney, required an upgrade to its ageing hot water infrastructure. The existing Raypak boiler system was due for replacement, with the project focused on improving energy efficiency, increasing reliability and providing additional capacity to meet the building's ongoing hot water demands.
As the building remained fully occupied throughout the project, maintaining resident comfort and continuous hot water supply was a key priority.
Challenge
The primary challenge was replacing the ageing hot water system within a constrained timeframe while minimising disruption to residents. With the building fully occupied, it was essential to maintain hot water availability throughout the upgrade process.
The new system also needed to deliver improved efficiency, greater capacity and increased redundancy to ensure long-term reliability and support future demand.
Solution
Rinnai supplied and installed a new commercial hot water solution comprising two HD28i Heavy Duty Continuous Flow Water units and a Demand Duo system.
The retrofit replaced the ageing boiler infrastructure with a modern, energy-efficient system designed to improve operational performance and reliability. The upgraded configuration provides increased capacity and built-in redundancy, helping ensure dependable hot water supply while reducing operating costs.
Outcome
The new Rinnai solution combining HD28i Continuous Flow Water Heaters with a Demand Duo system improved energy efficiency, reduced running costs, increased hot water capacity and enhanced reliability, while maintaining service continuity for residents throughout the upgrade.
By upgrading to a modern Rinnai hot water solution, Maestri Towers gained a more efficient, reliable and future-ready system. The installation delivered improved energy performance, lower operating costs, greater redundancy and increased capacity, providing residents with dependable hot water and long-term operational benefits.
