Project Overview

The Swan Hill District Health Emergency Department redevelopment represents a major milestone in Victoria’s investment in regional healthcare, with a combined $65.7 million contribution from the Victorian and Commonwealth Governments. Serving 35,000 people across a 100 km radius, the facility now provides a fully integrated 143-bed rural health service that meets contemporary clinical and community needs.

The redevelopment more than doubled emergency treatment capacity from seven to fifteen points of care, adding a four-bed short-stay unit alongside expanded medical imaging, assessment, and triage zones. Designed to deliver fast, high-quality emergency care around the clock, the project required mechanical and hydraulic systems that could guarantee continuous hot water and stable heating for all clinical functions, even under peak operational loads.

Sustainability Objectives

Healthcare facilities demand uncompromising reliability—but they also have a growing obligation to minimise environmental impact. From early design, Swan Hill District Health and project engineers prioritised sustainability and resilience in the selection of building services systems.

By choosing a dual all-electric CO₂ heat pump configuration, the redevelopment eliminates fossil fuel dependence for both heating and hot water. This approach ensures:

  • Zero on-site emissions for core thermal energy needs
  • Improved energy performance and reduced operational risk
  • Alignment with Victoria’s decarbonisation roadmap and public health sustainability goals

Using natural refrigerant CO₂ technology future-proofs the installation against evolving refrigerant regulations while providing the temperature stability required for critical healthcare operations.

Heating and Hot Water System

Automatic Heating delivered a comprehensive mechanical solution engineered for healthcare-grade reliability and efficiency.

Hot Water System

  • 3 × Revere CO₂ Heat Pumps (CHP-080Y) — providing instant, high-temperature hot water for clinical and procedural areas
  • Thermex Stainless Steel Storage Tanks — ensuring consistent supply and rapid recovery across 24/7 demand cycles
  • Duraflex Expansion Tanks — maintaining system balance and pressure stability for continuous operation

Heating System

  • 4 × Revere AHG130HT High-Temperature Heat Pumps — serving the building’s space heating network with precise temperature control and redundancy
  • Integrated control architecture — managing both systems for optimal performance and energy efficiency

This dual-system approach ensures total redundancy and uninterrupted service delivery, combining sustainability with the operational assurance required for emergency healthcare environments.

Outcome and Community Impact

The new system underpins the facility’s ability to provide continuous emergency care with reliable, high-temperature hot water and climate control—both critical for patient comfort, staff efficiency, and infection control.

Key benefits include:

  • Expanded treatment capacity: 15 points of care (up from 7) plus a four-bed short-stay unit
  • Improved patient flow: faster treatment turnaround and reduced waiting times
  • Future-ready infrastructure: sustainable technology supporting decades of dependable service

By integrating Automatic Heating’s CO₂ and high-temperature heat pump systems, Swan Hill District Health now operates with enhanced resilience, reduced emissions, and lower long-term operating costs—delivering contemporary healthcare standards for rural Victoria while demonstrating how sustainable mechanical systems can directly improve community health outcomes.
