Brisbane and South-East Queensland hydronic specialists since 1998. Reversible hydronic heat pumps for year-round heating and cooling, slab and underfloor heating, panel radiators, electric hydronic boilers and commercial hot water — designed and installed from our Banyo showroom.
AHHAC has been installing hydronic heating in Brisbane and South-East Queensland since 1998 — across high-end Hamilton and New Farm renovations, Gold Coast canal-front new builds, hinterland properties from Tamborine to Maleny, and architect-designed homes on Sunshine Coast acreage. Our Brisbane showroom is at Banyo QLD 4014 with same-day stock and a direct line on 1300 76 53 39.
Brisbane's hydronic market is heavily weighted toward cooling — chilled-water systems pull humidity AND temperature out of the air without the dust circulation of ducted reverse-cycle. The standard Brisbane spec: a reversible heat pump hydronic system driving chilled-water underfloor or fan coils in summer (silent, allergen-free) and gently warming the same network on cool winter mornings.
For QLD commercial sites — hotels, hospitals, aged care, schools, gyms — we specify the MAXA HWA2 commercial range: industrial reversible chillers and heat pumps producing 73-192 kW heating output and hot water to 78°C. The HWA2 is the only R290-natural-refrigerant monoblock on Queensland's Type B Gas Device Register.
Brisbane has fewer dedicated hydronic specialists than Sydney or Melbourne — most installers are general air-conditioning contractors adding hydronic as a sideline. AHHAC is a dedicated hydronic and plumbing specialist with a full Brisbane design team, in-house service technicians and same-day parts inventory.
Every Brisbane install carries our workmanship warranty on top of the manufacturer cover. We're authorised installers for Maxa, Immergas Magis, Viessmann Vitocal heat pumps and the full hot water range from Rheem and Rinnai. Our service team handles annual maintenance with manufacturer-validated warranty cover.
For Brisbane and Gold Coast coastal sites, we apply additional anti-corrosion treatment on heat-pump outdoor units (mandatory in high-salt areas per Immergas installation compliance). AHHAC's salt-spec install package extends the heat-pump outdoor unit life by 30-40% compared to a standard install in coastal QLD conditions.
Every Brisbane project starts with a heat-loss calculation and a fixed-fee design. We size each system to your building, your climate and your living patterns.
