Heat pumps are 3–4× more efficient than traditional electric storage systems. Pair one with rooftop solar and you can effectively heat your water for free during the day. Generous Victorian rebates often cover most of the upgrade cost.

Premium heat pumps brands, hand-picked.
We install eight of Australia's most trusted heat pump brands — Aether, Apricus, Aquatech, Emerald, iStore, Powerbay, Reclaim and Rinnai — chosen for proven Victorian reliability, strong VEU rebate eligibility and real local warranty support.
Reclaim Energy
The benchmark CO₂ split heat pump for Australian homes.
Reclaim Energy is widely regarded as the premium heat pump on the Australian market. Its split-system design uses natural CO₂ (R744) refrigerant — a Japanese-engineered Mitsubishi compressor sits outside, away from the tank, for whisper-quiet operation. CO₂ runs efficiently even on cold Victorian mornings, delivering hotter water (up to 63°C) and faster recovery than typical R290/R32 units. Available with three tank choices (glass-lined, stainless steel and stainless steel squat) in 250L, 315L and 400L sizes — there is a Reclaim for every household.
Aether
Affordable VEU-friendly 270L family heat pump.
Aether's HP270 has become one of the most cost-effective ways to switch from electric or gas hot water in Victoria. The all-in-one 270L unit ships with a smart controller, R290 natural refrigerant and qualifies for full VEU + STC rebate value — meaning many Victorian households end up paying very little out of pocket.
iStore
Australia's best-selling all-in-one heat pump.
iStore is one of the most popular heat pump brands in Victoria — partly because of generous VEU rebate value, and partly because the integrated all-in-one design is incredibly easy to install. Australian-designed with a smart Wi-Fi controller and PV-boost mode, iStore lets you schedule the unit to soak up your free midday solar generation. The 180L compact and the 270L workhorse cover most Victorian households.
Aquatech
Inverter-driven R290 heat pumps with smart Wi-Fi.
Aquatech is an Australian-owned brand specialising in modern inverter-driven heat pumps using natural R290 propane refrigerant. The variable-speed compressor ramps up and down to match demand — quieter, more efficient and longer-lasting than fixed-speed units. The Dynamic and Rapid ranges are popular Victorian VEU choices for households that want premium R290 performance at a sensible price.
Apricus
R290 heat pump from Australia's solar hot-water specialist.
Apricus has been a leader in Australian solar hot water for over two decades, and brings that same engineering pedigree to its heat pump range. The 260L all-in-one runs on natural R290 refrigerant with an inverter compressor, smart controller and a track record of reliable Australian service backing. A great mid-range all-rounder with strong VEU rebate value.
Emerald Energy
Wide-range R290 heat pumps engineered for Victorian homes.
Emerald Energy offers one of the broadest VEU-eligible heat pump ranges in Australia, with PRO and SELECT models in 220L, 270L and 320L tank sizes. All models use natural R290 propane refrigerant, inverter-driven compressors and Wi-Fi smart controllers. Designed and supported in Australia, Emerald is a strong all-rounder when you want flexibility on tank size and a competitive rebate-adjusted price.
Rinnai
Japanese hot water heritage you already know and trust.
Rinnai is one of the most trusted hot water brands in Australia, with decades of plumbing and gas expertise. The Enviroflo EHPA315 brings that reliability into the heat pump era — a 315L all-in-one with a robust build, dependable performance and the strongest national service network of any brand we install. The safe choice for households that want a household-name brand standing behind the unit.
Powerbay
Gen 2 hybrid inverter heat pump with electric boost.
The Powerbay 300L Gen 2 is a modern hybrid heat pump — an R290 inverter compressor for everyday efficiency, plus a built-in electric element for fast recovery and cold-weather backup. The 300L tank suits busy households, and the Wi-Fi controller integrates beautifully with rooftop solar via PV-boost mode.
