Selection checklist (AU)

• Functions: cooling + heating + DHW on one platform
• Tariff: off‑peak / controlled load availability
• Space: reducing plant rooms improves usable/rentable area
• Safety: preference for “zero indoor high‑pressure refrigerant”
• DHW: high hot‑water demand strengthens business case

Typical configuration (concept)

• Outdoor heat‑pump host (refrigerant side kept outside)
• Energy storage tank (cooling/heating buffer)
• Domestic hot water tank (24/7 supply)
• Indoor terminals: fan coils + optional hydronic underfloor loops

Australia notes (practical)

• Climate: consider NCC climate zone and seasonal profile.
• Tariffs: confirm off‑peak windows; controlled load can materially improve economics.
• Compliance: confirm refrigerant containment, plumbing standards, and building services approvals per project.
