Heat pump hydronic heating from authorised Maxa, Immergas and Viessmann suppliers. Air-source and geothermal heat pumps for hydronic heating, cooling and hot water across Sydney, Melbourne and Queensland.
A heat pump hydronic heating system replaces the gas or electric boiler in your hydronic loop — driving the same radiator, underfloor and fan-coil network with all-electric refrigerant-cycle efficiency. Heating COP of 3.5–5.5 means every 1 kW of electricity becomes 3.5–5.5 kW of heat in the room — typically 65–75% lower running cost than the same hydronic system on gas.
AHHAC is an authorised supplier of Italian-engineered Maxa heat pumps (i-290 R290 and i-32V5 R32 monoblock series), Immergas Magis heat pumps, and Viessmann Vitocal hydronic heat pumps. We also install Mitsubishi Ecodan, Daikin Altherma and Bosch Compress where the project calls for a Japanese or German engineering footprint.
Heat pump hydronic heating is the lowest-carbon, lowest-running-cost option for any Australian home with rooftop solar PV. The same unit that heats your radiators or underfloor in winter reverses cycle in summer to deliver chilled water through the same pipework — silent, allergen-free hydronic cooling that no ducted system can match.
Sydney and NSW homeowners pair their heat pump hydronic system with a 5–10 kW solar PV array for near-zero net annual energy cost. The 30+ year design life of the hydronic distribution means only the heat pump itself needs replacement at the 12–15 year mark — and even then, just swap the outdoor unit, the rest of the system keeps running.
Market-leading Italian R290 monoblock heat pump for hydronic heating. Heating COP 4.94, 6–27 kW output, the only R290 monoblock on QLD's Type B Gas Device Register.
Italian-engineered R32 inverter monoblock heat pump. 11 chassis sizes from 6.1 to 17.9 kW heating, COP 4.9. VIPAC certified for Australian conditions.
Italian-engineered air-source heat pump hydronic range — Magis Pro and Audax monoblocks for retrofit-friendly installs, plus the Hercules Pro hybrid (heat pump + gas) for cold-climate sites.
German-engineered hydronic heat pumps with R290 DHW models and full hydronic heating units. Vitocal 161-A heat pump COP 4.15.
i-290 uses R290 (propane) refrigerant — natural, GWP=3, highest efficiency, QLD Type B Gas approved. i-32V5 uses R32 — broader chassis range (11 sizes vs 3), GWP 675. Both are made in Italy with 7-year domestic warranty. We'll match to your project.
Yes — Maxa heat pumps are tested down to -15°C ambient. Australian climates are well within operating range, including the Snowy region. Performance drops slightly in extreme cold but they continue to deliver heat reliably.
Heat pump if: you want all-electric (works with solar PV), want lowest running cost long-term, want integrated cooling. Gas boiler if: you have cheap gas, want fastest warm-up, want lowest install cost. We spec both options for comparison.
