NeoPower Heat Pump Hot Water Systems

NeoPower is the hot water brand of IMACA Pty Ltd, going since 2010 out of Scoresby in Melbourne's east, with thousands of systems installed around the country. Having the head office 40 minutes from most of our jobs makes warranty and parts a far easier conversation than chasing an offshore importer.

The current range is the Black Shield, also badged Heat Pump 2.0. It ditches the old single-speed on-off design for a variable-speed inverter compressor that ramps up and down with what the house is actually drawing — steadier water temperature, less energy wasted and much quieter running.

The headline number is a COP of 5.4: 5.4 kW of heat for every 1 kW of power at 20°C air. That's from the inverter, a microchannel heat exchanger and high-efficiency EC fan motors working together, and it's the reason the Black Shield sits near the top of the published STC and VEEC tables — which means more rebate coming off your quote.

Three sizes: 210L for a couple, 270L for a typical family and 320L for a full house. All run 410 g of R290 natural refrigerant (GWP 3), a matte black ABS shell over an enamel-coated extra-thick carbon steel tank, a colour touch screen, Wi-Fi through the free Smart Life app and Modbus for smart-home integration.

We also stock the Black Diamond, NeoPower's earlier all-in-one. Same Scoresby outfit and the same R290 charge, but a single-speed compressor and a published COP of 4.33 rather than 5.4. Where it hits back is corrosion protection — three anodes instead of the usual one — plus a flat 6 years on all system parts. It comes in 210L, 260L and 315L, and it's the pick if you want the cheaper sticker and don't need the inverter.
