Daldy Street

The brief was clear: Deliver a future-ready domestic hot water system that aligned with sustainability targets, reduced operational carbon, and provided long-term performance certainty for a premium CBD building. No shortcuts. No oversized systems. No compliance risk. Project Partners 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. Engineering Efficiency, Delivered 30 Daldy Street reflects Waterware’s integrated approach: System design. Component compatibility. Compliance confidence. Future-ready technology. All delivered as one coordinated solution.
