Hydronic heating, cooling and hot water for Mornington Peninsula homes — designed and installed by AHHAC, Melbourne's hydronic specialists, from our nearest showroom in Laverton North.
Hydronic heating on the Mornington Peninsula usually means in-slab underfloor driven by a reversible Maxa i-290 heat pump for permanent coastal homes, and fast-response radiators for weekenders that need to warm up quickly on arrival. Underfloor runs at 35–45 °C flow temperatures, and the pipework is built for a 30+ year life. AHHAC designs and installs across the Peninsula, from Mount Eliza to Portsea and the Red Hill hinterland, from our Laverton North showroom.

ImmergasSimeThermaSkirt™The Mornington Peninsula — from Mount Eliza and Mornington down to Portsea, and inland to Red Hill and Main Ridge — is one of Victoria's strongest hydronic markets. Cold, wind-exposed winters, a mix of architectural coastal homes, weekenders and hinterland acreage, and owners who want quiet, even warmth without visible plant all point to hydronic. AHHAC designs and installs the full range across the Peninsula: in-slab and in-screed underfloor heating, European panel radiators, and all-electric heat pump systems.
For new coastal builds we favour a reversible Maxa i-290 heat pump driving in-slab underfloor — gentle winter warmth, silent summer cooling on the same pipework, and running cost near zero once paired with rooftop solar. For weekenders and holiday homes, fast-response radiators make more sense so the house warms quickly on arrival. We serve the Peninsula from our Laverton North showroom, part of AHHAC Melbourne.
The Peninsula isn't one climate. A hinterland block at Red Hill or Main Ridge sits well above the bay, catches more frost, fog and rain, and needs a noticeably bigger system than a home of the same size in Sorrento or Rye. Down on the coast it is wind and salt that drive the design: exposed clifftop and beachside homes lose heat faster through glass and walls, and their outdoor units need sheltered positions and corrosion protection. We run the heat-loss calculation for your specific site rather than applying one Peninsula-wide figure.
Two checks come before any equipment is chosen. First, power: older rural connections can have limited supply capacity, so we confirm what the switchboard and supply can carry before sizing the heat pump. Second, water: many hinterland homes run on rainwater tanks, and soft, slightly acidic tank water isn't ideal for filling a closed heating circuit. We treat the fill water and dose inhibitor at commissioning using our hydronic water treatment range, which protects pipework, pumps and the heat exchanger for the long haul. Parts of the hinterland are also bushfire prone, so on new builds we work to the BAL requirements on your plans.
Part-time homes. Weekenders are where we see the most energy wasted. Switching a system fully off between visits means a cold, damp house on arrival and a long, expensive warm-up; leaving it at full temperature heats an empty house all week. The better approach is a low set-back temperature that keeps the building fabric dry and frost-free, with a remote boost from your phone a few hours before you leave Melbourne. Even with radiators, that set-back means the house is comfortable within the first hour rather than the first evening.
Peninsula installs and annual services are scheduled in blocks from our Laverton North showroom as part of AHHAC's Melbourne hydronic heating team, and coastal outdoor units have their coils checked for salt build-up at every visit.

AHHAC's in-house design and service team — licensed plumbers and hydronic engineers (Lic 262528C) who have designed and installed 2,400+ hydronic heating, cooling and hot water systems across Australia since 1998.
We design hydronic heating from a room-by-room heat-loss calculation, install it with our own licensed plumbers to AS/NZS 3500 (plumbing) and AS/NZS 5601 (gas), commission and document it, and service it for the life of the system. Nothing is subcontracted out.

"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."
"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."
