At a Glance: Neopower Black Diamond Heat Pump Scores 3.5 Out of 5
Scoring is based on our heat pump scorecard which is consistently applied to each brand and heat pump on the Australian market.
$ Price: The retail cost of the Neopower Black Diamond 210L model is under $2,500, placing it in the lowest price bracket on our scorecard and offering value for entry-level buyers.
- Company Backing and Trustworthiness: Neopower, trading under Imaca Pty Ltd, has been operating since 2010 and has a physical office in Scoresby, Victoria. However, the company has fewer than 20 confirmed staff in Australia and does not offer products beyond hot water systems. Based on our scoring system, Neopower receives 2 points in this category.

- Customer Reviews: Based on verified customer reviews through Solar Choice’s independent platform, Neopower has received a review average within the 4.25–4.5 range, earning 4 points.
- Functionality: The Neopower Black Diamond 210L unit includes WiFi app control, an LCD screen, and supports multiple programmable heating schedules. It also has a heating power of 13.8W per litre. However, the noise level rating of 42 dBA does not specify the measurement distance, so it does not earn the point for quiet operation. This scores 4 points.

Pros and Cons
Pros
- Cost-Effective
With models priced just above $2,500, the Neopower Black Diamond falls within the lowest price bracket on our scorecard, offering a high feature-to-cost ratio. - Smart Functionality
Includes an LCD touchscreen and WiFi app integration via the Smart Life app, allowing remote control and system monitoring. - Programmable Timers
Offers up to three separate time schedules for heat pump operation, allowing greater control over energy usage patterns. - Heating Capacity
The 210L unit delivers a heating power of 13.8W per litre, exceeding the threshold of 10W/L for strong thermal performance. - Climate Adaptability
Designed for operation in ambient temperatures ranging from -7°C to 43°C, suitable for varied Australian climates. - Environmentally Friendly Refrigerant
Uses R290 refrigerant with an ultra-low Global Warming Potential (GWP) of 3, aligned with modern sustainability standards. - Auxiliary Heating Element
Built-in electric element can boost water temperatures up to 75°C when needed.
Cons
- Limited User Feedback
As of early 2025, the product has a relatively short time on the market, and a limited volume of customer reviews means long-term performance is not fully established. - Limited Labour Warranty
Labour coverage is capped at 2 years, which is modest compared to premium systems that offer 5 years or more. - Unverified Noise Level Testing
Although the unit is rated at 42 dBA, the manufacturer has not specified whether this measurement was taken at 1 metre, which is the industry standard for evaluating noise performance. - Restricted Model Range
Current options include only 210L and 260L capacities, with a 315L model pending release. Larger or smaller households may find fewer tailored options.
Verdict: Is the Neopower Heat Pump Worth It?
However, there are a few trade-offs to consider. The 2-year labour warranty is shorter than what some competitors provide, and the noise level—while low—has not been verified at the standard 1-metre distance. Additionally, as a newer product with limited customer reviews, its long-term reliability is still being established.
