Rinnai heat pump: Strengths and weaknesses
Rinnai has a substantial presence in Australia’s hot water market, with several current Enviroflo ranges covering different household requirements.
The Enviroflo GR Series, for example, is available from 180L to 300L, with models designed for up to six people. It offers Wi-Fi control, multiple operating modes, R290 refrigerant, solar PV compatibility and operation from approximately -7°C to 45°C.
Rinnai’s larger Enviroflo AR Series extends capacity to 300L and 340L, making it particularly relevant to larger households. The current AR models use R290, provide built-in Wi-Fi and have a published COP of approximately 8.4 under the manufacturer’s test conditions.
Rinnai heat pump advantages
- Broad selection of integrated and split configurations.
- Australian-designed and made options are available.
- Strong solar PV integration on selected models.
- R290 refrigerant is used across several current ranges.
- Multiple tank sizes suit households of all sizes.
- Some current split models carry 10-year cylinder warranties.
Potential Rinnai drawbacks
Rinnai’s extensive range can complicate model selection. Installation requirements, capacity, electrical supply, and warranty terms vary considerably between products, so comparing the exact model is more useful than comparing brands in general.
Haier heat pump: Strengths and weaknesses
The current Haier heat pump range includes Monoblock and Split System products. Haier states that its Monoblock systems can reduce electricity used for water heating by 69% to 79% compared with standard electric resistance water heaters, based on specified AS/NZS 4234 testing conditions.
The latest Monoblock range includes 200L, 250L and 330L options, while the Split System configuration provides a 280L solution with a separate heat pump and cylinder. The split configuration can provide greater flexibility where the compressor needs to be positioned away from the storage tank.
Haier heat pump advantages
- High reported energy efficiency.
- R290 refrigerant in the current Monoblock range.
- SmartHQ app connectivity.
- Solar PV operating modes.
- Operating range extending from approximately -7°C to 45°C on Monoblock models.
- Five-year manufacturer warranty, plus an additional two-year cylinder parts warranty.
Potential Haier drawbacks
The Split System uses R32 rather than R290, and its specifications differ from the Monoblock range. Buyers should therefore avoid assuming that every Haier heat pump delivers the same efficiency, noise level or operating characteristics.
Which heat pump is more energy efficient?
Efficiency is one of the biggest reasons Australian households are considering heat pumps. The technology can significantly reduce electricity consumption compared with conventional electric resistance heating, and the benefit can become even greater when the system is coordinated with rooftop solar.
Both Rinnai and Haier publish strong efficiency figures for selected models. For example, Rinnai’s Enviroflo S 7.0kW split heat pump lists a COP of 9.2 under its stated test conditions, while Haier reports 69% to 79% electricity reductions for its Monoblock range compared with conventional electric storage.
However, these figures should not be compared as if they were identical measurements. COP, energy reduction percentages, and test conditions can vary, so actual household performance depends on climate, water demand, temperature settings, and operating schedules.

Rinnai vs Haier heat pump: Which is better for solar homes?
Both brands can work well with rooftop solar. Rinnai offers PV-compatible operating modes on selected Enviroflo products, while Haier’s SmartHQ system can prioritise solar-generated energy on compatible models.
This can be particularly useful because excess solar electricity can be converted into stored hot water rather than exported to the grid. A properly timed heat pump can therefore become another means of increasing household solar self-consumption.
For solar households, the better choice is usually the system with the right tank size, controls and installation configuration rather than simply the brand with the highest advertised COP.
What about rebates and STCs in 2026?
Eligible air-source heat pumps can qualify for Small-scale Technology Certificates (STCs) under Australia’s Small-scale Renewable Energy Scheme. The Clean Energy Regulator maintains a register of eligible heat pump models, and the current register includes air-source heat pumps rated up to 425 L.
The value of the incentive depends on factors including the installation postcode, the eligible system, and the deeming period. For systems installed in 2026, the deeming period is five years, while it falls to four years for 2027 installations.
State and territory incentives can also change. Check the latest government information before signing a contract, and confirm that the exact model and installation configuration meet eligibility requirements.
Rinnai vs Haier heat pump: Which should you buy?
