Running costs
About $1,242 a year back in your pocket
Based on a four-person Victorian household — roughly 4,500 kWh of water heating a year at 30c/kWh. At a COP of 4.73, this unit only needs about 951 kWh to do the same job. Run it on the timer through the middle of the day and most of that comes off your roof, not the grid.
Got rooftop solar?
Time the heat pump to soak up your daytime output
Every kWh you self-consume is worth 30c instead of the 3c feed-in you'd get for exporting it — that's the solar saving baked into the numbers below.

Powerbay Gen II Inverter
Inverter smarts without the premium price tag
The Gen II runs an AI-controlled inverter compressor, so it ramps output to suit the house instead of banging on and off. 2.65 kW of heat from just 0.56 kW of power — a COP of 4.73 — on 340 g of R290 natural refrigerant. Microchannel exchanger wrapped around an enamel-lined tank, IPX4 rated, and it keeps pulling heat from the air down to -7°C.
Three operating modes
- Standard mode
- The factory default. Heat pump runs first, then the element finishes the job once the compressor hits its limit. Set and forget for most homes.
- Eco mode
- Heat pump only — the element stays out of it. Cheapest way to run the tank, and the pick if you've got solar heating during the day.
- Hybrid mode
- Heat pump and element together for the quickest recovery. Handy for a full house or a cold snap. Reverts to Standard after 24 hours.
Warranty
- TankReplacement warranty — a 500 kPa pressure limiting valve must be fitted on the cold inlet
- 5 years
- Heat pump parts
- 2 years
AI-controlled inverter
Variable-speed compressor that reads demand instead of banging on and off. Steadier water temperature and less power drawn on a mild Melbourne day.
COP up to 4.73
2.65 kW of heat from 560 W of power on the 200L and 250L (2.35 kW on the 300L) — around 75% less power than an old resistive electric tank.
R290 natural refrigerant
340 g of propane with a global warming potential of 3, instead of the synthetic gases in the thousands that plenty of brands still run.
Weekly sterilisation cycle
After seven days of running, the unit automatically lifts the tank to knock off any bacteria or legionella. No button to press.
Built to last the distance
Enamel-lined thick carbon steel tank with a magnesium anode, tested through 250,000 pulsation cycles, IPX4 rated for outdoors.
Wi-Fi app control
Full control from your phone — modes, target temperature, schedules and unit status, so you can shift heating onto your cheap power window.
The Gen II range side by side
| Model | Tank | Suits | COP | Size (Ø × H) |
|---|---|---|---|---|
| PBG2-200RE-HYBRID | 200 L | 1–3 people | 4.73 | Ø650 × 1890 mm |
| PBG2-250RE-HYBRID | 250 L | 3–4 people | 4.73 | Ø650 × 1950 mm |
| PBG2-300RE-HYBRID | 300 L | 4–6 people | 4.2 | Ø650 × 2030 mm |
Powerbay's tank warranty requires a 500 kPa pressure limiting valve on the cold inlet — we fit one on every install as standard, so your cover stays intact.
Straight talk
Our honest take on Powerbay
- AI-controlled inverter compressor, not the old on-off design
- COP 4.73 on the 200L and 250L, on 340 g of R290
- Weekly automatic sterilisation cycle and Wi-Fi app control
- 5-year tank replacement warranty, 250,000-cycle tested
- 46 dB(A) — louder than the quiet leaders
- Labour cover is short compared with the premium brands
- Tank warranty needs a 500 kPa PLV fitted on the inlet
