The Kingfisher Grove project, consisting of 142 domestic hot/warm water (DHW/DWW) Regudis stations, was designed to provide efficient hot water delivery to the retirement village’s 144 apartments and communal areas. The system’s innovative design significantly optimized the space and energy infrastructure while maintaining performance and reducing costs.
- Location: Jordan Springs (NSW)
- Industry: Commercial
Our Process:
Building A serves as the primary heating source for all site apartments, communal spaces, and services. It includes 36 DHW stations for apartments and 3 DWW stations for communal and service areas. A 150 kW heat pump, operating at 65°C, supplies 4,500 liters of storage to meet peak DHW demands. The system’s design provided efficient hot water delivery without the need for oversized heat pumps, achieving a coefficient of performance (COP) of 3.2.
Masterflow Solutions designed and installed the heat pump system and buffer storage, ensuring scalability for future demands of Buildings B and C. Building A’s small plant footprint and local Regudis installations freed up space, allowing for more lettable areas. This setup maintained continuous tap temperatures of 60°C (DHW) for apartments and 43°C (DWW) for communal areas.
Outcomes:
The Regudis W-HTE installation delivered significant cost savings and operational efficiency for the retirement village:
- Cost Savings: The design eliminated the need for an additional electrical substation and site-wide infrastructure, saving the developer over $500,000.
- Efficiency: The 150 kW heat pump and 4,500L storage met peak demands without increasing energy consumption.
- Sustainability: Instantaneous hot water production reduced water wastage, leading to fewer complaints from residents.
- Future-Proofing: The system was designed to scale, accommodating future buildings (B and C) in Kingfisher Grove.
The Regudis W-HTE system proved to be a space-saving, energy-efficient solution, reducing both capital and operational costs while maintaining optimal service for the residents of Kingfisher Grove.
