Heat Pumps — Hydronic
Air-source and ground-source heat pumps for hydronic heating, cooling and hot water. AHHAC is an authorised supplier of Maxa and Immergas for Australia.
Air-source and ground-source heat pumps for hydronic heating, cooling and hot water. AHHAC is an authorised supplier of Maxa and Immergas for Australia.
A hydronic heat pump replaces the boiler in your hydronic system — driving the same network with all-electric, refrigerant-cycle efficiency. COP of 3.5–5.5 means every 1 kW of electricity becomes 3.5–5.5 kW of heat.
We're an authorised supplier of Maxa and Immergas (both Italy) — premium Italian-engineered units rated for Australian conditions. We also install Mitsubishi Ecodan, Daikin Altherma, and Bosch Compress.
Market-leading Italian R290 monoblock heat pump. Heating COP 4.94, 6–27 kW, the only R290 monoblock on QLD's Type B Gas Device Register.
Italian-engineered air-source heat pump range — straight Magis Pro and Audax monoblocks for retrofit-friendly installs, plus the Hercules Pro hybrid (heat pump + gas) for cold-climate sites.
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.
