Hydronic heating, cooling and hot water for Brighton homes — designed and installed by AHHAC, Melbourne's hydronic specialists, from our nearest showroom in Laverton North.
Hydronic heating in Brighton usually means in-slab underfloor heating driven by an all-electric heat pump, running at low 35–45 °C flow temperatures through bayside Melbourne's long winters of roughly 1,500 heating degree-days. Period Victorians and Edwardians usually suit radiators instead. A cold-rated Maxa i-290 heat pump also reverses for summer cooling. AHHAC designs every Brighton system from a room-by-room heat-loss calculation and installs from our Laverton North showroom.

ImmergasSimeThermaSkirt™Brighton's bayside Melbourne homes — from period Victorians and Edwardians to substantial contemporary rebuilds — sit in one of Australia's coldest metropolitan micro-climates, with long winters that make hydronic heating close to essential. AHHAC designs and installs the full range across Brighton, with in-slab hydronic underfloor heating the standout for the climate: silent, even, whole-home warmth that runs at low flow temperatures.
Because Brighton carries roughly 1,500 heating-degree-days, we size every system to the coldest week and favour all-electric heat pump hydronic heating — the Maxa i-290 is rated to −25 °C, comfortably inside bayside conditions, and reverses for silent summer cooling. Brighton is served from our nearby Laverton North showroom, part of AHHAC Melbourne.
Brighton's newer homes tend to share one feature: a wall of glass facing the bay. It is the reason people build there, and it is also the biggest single influence on how a hydronic system should be designed. Even good double glazing loses several times more heat than an insulated wall, and on a cold July evening a tall pane sends a downdraught of chilled air across the floor that you feel long before the thermostat does.
The bay also brings wind and salt. We treat exposed beachside lots as high-exposure sites in the heat-loss calculation, because wind strips heat from glass and walls faster. Outdoor units go on the sheltered side of the house where possible, get corrosion protection on beachfront sites, and have their coils checked and rinsed at every annual service, because salt build-up quietly cuts efficiency and shortens a unit's working life.
Brighton's period Victorians and Edwardians present a different challenge — solid walls, high ceilings and suspended timber floors — and our hydronic heating Melbourne page covers the radiator-led approach we use for them. If you are rebuilding, settle the glazing specification, trench heater positions and plant location with us before the slab is poured, not after. Every Brighton system, rebuild or period home, is designed and serviced from our Laverton North showroom.

"We commissioned AHHAC after another contractor abandoned the job halfway. They took over the design, fixed the existing issues, finished the install and gave us a five-year warranty. They saved the project."
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook. Couldn't ask for more from a trade partner."
