Consultant: Agile Engineering Consulting
Builder: Mansons TCLM
System Installer: Express Plumbing
Delivered By Experts
The installation was executed by Express Plumbing, demonstrating exceptional craftsmanship in connection, layout, and commissioning.
In complex commercial environments, execution matters as much as design. This project delivered both.
The Challenge
Commercial buildings in the CBD present unique demands:
• High and variable hot water usage
• Tight plant room constraints
• Strict sustainability and compliance requirements
• Long-term OPEX sensitivity
• Green Star performance alignment
The system needed to deliver reliable 65°C hot water, operate efficiently year-round, and integrate seamlessly with the broader mechanical design.
The Waterware Solution
Waterware engineered a PureFlow-designed commercial heat pump system built around the Ritter R290 platform.
Technical Summary
Project: 30 Daldy Street, Wynyard Quarter
System Type: Commercial Domestic Hot Water Heat Pump
Heat Pumps: 4 × Ritter Thermal R290 (20kW)
Buffer Tank: 500L Ritter
Storage: 3 × 500L Protankplus 2.0 (10 bar)
Design Platform: PureFlow Commercial Modelling
Compliance: 6-Star Green Star aligned
Designed using Waterware’s PureFlow modelling tools, the system was value-engineered to meet load requirements without oversizing, ensuring maximum efficiency and compliance confidence.
Heat Pump Platform
Ritter R290 commercial heat pumps provide high-temperature output using natural refrigerant R290, delivering strong performance with low environmental impact.
Thermal Storage Strategy
The combination of buffer and high-pressure storage tanks ensures:
• Stable temperature control
• Reduced compressor cycling
• Peak demand smoothing
• System longevity
Controls & Commissioning
Caleffi control components provide accurate system balancing, protection, and long-term reliability. Full commissioning documentation was delivered to support mechanical sign-off and compliance validation.
Performance & Sustainability
• Natural refrigerant R290 with ultra-low GWP
• Designed to meet 6-Star Green Star performance objectives
• High-efficiency heat pump cascade configuration
• Reduced operational carbon footprint
• Optimised plant room footprint
PureFlow modelling ensured carbon reduction and performance targets were calculated and validated before installation.
This wasn’t just a heat pump install.
It was a system-level engineering outcome.
