For Melbourne's long, cold winters, heat pump hydronic heating is now the lowest-running-cost way to heat a home — and the only system that reverses to give you silent chilled-water cooling in summer. A hydronic heat pump replaces the gas or electric boiler in your system, driving the same radiators, underfloor loops and fan coils with all-electric, refrigerant-cycle efficiency. With a heating COP of 3.5–5.5, every 1 kW of electricity becomes 3.5–5.5 kW of heat — roughly 60–75% cheaper than gas at 2026 tariffs, and near-zero with rooftop solar PV.

AHHAC is an authorised supplier of all three major hydronic heat-pump brands — Maxa i-290 (R290), Maxa i-32V5 (R32) and Immergas Magis — so the Melbourne recommendation is genuinely independent. See how they compare in our Maxa vs Viessmann vs Immergas breakdown.

Sizing a heat pump for Melbourne's climate

Melbourne carries roughly 1,500 heating-degree-days and a −1 °C design temperature — about double Sydney's load. That means the heat pump has to be sized correctly for the coldest week, not the average. For the coldest Melbourne-fringe suburbs (Macedon, Daylesford, the Dandenongs, Mornington foothills) we often spec the Immergas Magis Hercules Pro hybrid, which switches automatically to a condensing gas backup when the heat-pump COP drops below economic. Pair the heat pump with hydronic underfloor heating or panel radiators and AHHAC will run a heat-loss calculation before quoting.

Common Melbourne questions

Heat Pump Hydronic Heating Melbourne — FAQ

Do heat pumps work in Melbourne winters?+
Yes — the right ones. The Maxa i-290 is rated to −25 °C ambient and holds full output down to −7 °C, comfortably covering Melbourne and its cold fringe. For the very coldest sites we spec the Immergas Magis Hercules Pro hybrid, which switches to a gas backup automatically on the coldest mornings. A metro-grade heat pump designed for mild climates would struggle.
How much cheaper is a heat pump than gas in Melbourne?+
Typically 60–75% lower heating running cost at 2026 tariffs, because a heat pump delivers 3.5–5.5 kW of heat per 1 kW of electricity. Melbourne's long heating season makes that saving significant — often $700–$1,200 a year on a 200 m² home, and near-zero with rooftop solar PV.
Can a heat pump heat and cool my Melbourne home?+
Yes — a reversible hydronic heat pump heats in winter and delivers silent chilled-water cooling in summer through the same pipework (underfloor or fan coils). One piece of plant, one set of running costs, year-round comfort.
Which heat pump brand does AHHAC recommend for Melbourne?+
It depends on the job — we carry Maxa, Immergas and Viessmann. Maxa i-290 for all-in-one low-GWP performance, Immergas Magis for retrofits and cold-climate hybrids. See our Maxa vs Viessmann vs Immergas comparison, and we'll spec the right one after a heat-loss calculation.

"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."

"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
