Bethanie Aged Care Home in Subiaco required a reliable replacement for its underperforming hot water system while maintaining services for residents during installation.
Rinnai delivered a customised Demand Duo solution with HD28i Heavy Duty Continuous Flow Water Heaters, common flue integration and a Warm Water Valve, improving system reliability and meeting the facility's warm water requirements.
Background
Bethanie Aged Care Home in Subiaco, Western Australia, is a three-storey residential aged care facility requiring a dependable hot water supply to support resident comfort and daily operations.
The existing system consisted of seven internal continuous flow units connected to a common flue arrangement. As performance issues emerged, the facility sought a more reliable and effective solution capable of meeting operational and tempering requirements.
Challenge
The project involved replacing an underperforming warm water system within a functioning aged care facility where disruptions needed to be kept to an absolute minimum.
The upgrade was further complicated by limited plant room space, restricted daily cut-over windows of just four hours, and the need to modify existing flow and return pipework. To maintain service continuity, the installation was carefully staged, with manifolded units installed first, followed by the storage tank and finally the Warm Water Valve.
Solution
Rinnai designed and supplied a customised hot water solution centred around a Demand Duo DD428i system incorporating:
HD28i Heavy Duty Continuous Flow Water Heaters
Manifold Pack
440L Storage Tank
Warm Water Valve
Common Flue Connection
UV Unit
Dual Pump System
The new system was connected to the existing common flue header, reducing installation complexity while maximising available plant room space. A Warm Water Valve was incorporated to satisfy tempering requirements and ensure safe, controlled water temperatures throughout the facility.
Outcome
Rinnai's Demand Duo solution combined high-performance continuous flow technology, warm water temperature control and common flue integration to improve system reliability, maintain compliance and deliver dependable hot water throughout the aged care facility.
By carefully staging the installation and tailoring the system to the site's operational requirements, Rinnai successfully upgraded Bethanie Aged Care facility's hot water infrastructure with minimal disruption to residents.
The result is a more reliable and effective hot water solution designed to support long-term performance, resident comfort and operational confidence.
