A versatile R32 hydronic heat pump from Maxa — 11 chassis sizes covering 6.1 kW to 17.9 kW. Heating, cooling, domestic hot water and chilled potable water from a single Italian-engineered monoblock.

The Maxa i-32V5 heat pump is an Italian R32 monoblock that heats, cools and makes hot water up to 60 °C, offered in 11 chassis sizes from 6.1 kW to 17.9 kW heating with a heating COP of 4.9 on the 14 kW model. It suits homes in milder climates where precise sizing and budget matter most. AHHAC matches the chassis to a room-by-room heat-loss calculation and installs it with Maxa's 7-year domestic warranty.

The Maxa i-32V5 is a versatile R32 monoblock hydronic heat pump that delivers heating, cooling, domestic hot water and chilled potable water from a single outdoor unit. Designed and manufactured in Italy by Maxa, it offers exceptional flexibility with 11 chassis sizes to suit every project from compact homes to mid-sized commercial.
With heating COP of 4.9 (14 kW model) and cooling EER of 3.3 (11 kW model), the i-32V5 delivers industry-leading energy efficiency. R32 refrigerant has a significantly lower environmental impact than traditional refrigerants used in many heat pumps and air conditioners.
The Maxa R32 hydronic heat pump range has been independently tested and certified in Australia for all Australian conditions by Vipac Engineers & Scientists, ensuring reliable performance in our climate. Eurovent certified efficiency claims back the published performance figures.
11 chassis sizes covering nominal heating capacity from 6.1 kW to 17.9 kW and nominal cooling capacity from 5.2 kW to 15 kW — the broadest sizing flexibility in its class.
The Maxa R32 monoblock delivers up to 60°C hot water and as low as 5°C chilled water from the same unit. Pair it with underfloor heating, radiator panels, fan coils, hot water tanks or chilled-water cooling — one network, four functions.

A hydronic heat pump is an energy-efficient heating and cooling system that extracts heat from the air and transfers it to water, which is then circulated through a building to provide space heating, cooling, domestic hot water and chilled water.
R32 refrigerant has a lower environmental impact than traditional refrigerants used in many heat pumps and air conditioners. R32 has a global warming potential (GWP) of 675.
The Maxa i-32V5 Inverter Monoblock heat pump delivers industry-leading energy efficiency and performance. This product delivers heating with COP 4.9 (14 kW model) and cooling with EER 3.3 (11 kW model).

The i-32V5's biggest strength is choice. With 11 chassis between 6.1 kW and 17.9 kW, we can land very close to a home's calculated heat loss instead of rounding up to the next big unit — and that matters more than most buyers realise.
An oversized heat pump reaches temperature quickly, switches off, then restarts minutes later. That short-cycling wastes energy, adds wear and makes room temperatures less even. A correctly sized i-32V5 runs longer at lower speed, which is where inverter heat pumps are most efficient. Our process is simple: room-by-room heat loss, a realistic winter design temperature for your suburb, then the smallest chassis that covers it with sensible headroom.
In Sydney and Brisbane the cooling load often decides the chassis rather than heating. Because the i-32V5 can supply chilled water as low as 5 °C, we plan the cooling side properly:
Our hydronic fan coils and hydronic underfloor heating pages explain the emitter options, and our local notes on heat pump hydronic heating in Sydney and heat pump hydronic heating in Brisbane show how climate shifts the design.
Who it doesn't suit: if you're on a sub-zero site, need hot water hotter than 60 °C, or want the lowest-GWP refrigerant available, we'd usually point you to the R290 i-290 instead. For most mild-climate homes, though, a tightly sized i-32V5 is an efficient, cost-effective fit that stays quiet and comfortable through both seasons.
