5. iStore Heat Pumps
Model Highlight: iStore 270L Heat Pump Hot Water System
Company Overview:
iStore, a subsidiary of Solargain PV, has rapidly built its presence in the Australian heat pump market since 2019. With a growing product line that now includes solar inverters and batteries, iStore aims to offer an affordable path to energy efficiency for Australian households.
Performance Strengths:
iStore systems are praised for their strong value proposition. They offer one of the most affordable options available in the market while still maintaining solid functionality scores. Customer reviews highlight reliable day-to-day performance, and the 5-year comprehensive warranty (covering tank, refrigerant system, and electronics) helps build buyer confidence.
Areas to Consider:
Functionality remains fairly basic. Unlike premium systems, iStore models can lack some of the more advanced smart controls and operate at slightly higher noise levels, which could affect placement near living areas. The efficiency is good, but not market-leading.
Value Verdict:
If you’re looking for a budget-friendly heat pump with dependable performance and excellent warranty coverage, iStore is one of the strongest choices. Its high customer satisfaction scores affirm that this is a practical solution for households prioritising affordability and reliability over bells and whistles.

The brand is well-regarded for tech-savvy solutions and responsive support.
Areas to Consider:
While strong overall, EvoHeat’s warranty coverage is slightly less comprehensive than its top-tier peers. For some customers, this can be a concern given the premium positioning.
Value Verdict:
EvoHeat aims to bridge the gap between functionality and affordability. With excellent features and a solid track record, it’s a good choice for tech-oriented homeowners who want efficiency with convenience.
3. Apricus All-In-One Heat Pump

Value Verdict:

Performance Strengths:
Sanden scores top marks for warranty, company trust, and efficiency. With whisper-quiet operation, industry-leading efficiency, and stainless steel tanks designed for longevity. Customers consistently praise the unit’s durability and energy savings.
Areas to Consider:
Sanden units standard unit comes at a premium ($5,000+) and lacks timer multi-scheduling and Wi-Fi controller is sold separately (approx. $279–$400), which is required to access multiple timers and remote app control and extended warranty conditions. While long-term energy savings may offset this cost, the upfront investment may deter budget-sensitive buyers.
Value Verdict:
Sanden is the top choice for those who value performance, quiet operation, and long-term reliability. If you’re looking for the best in Japanese engineering and can afford a higher upfront cost, Sanden shouldn’t disappoint.
1. Reclaim Energy Heat Pumps
Model Highlight: Reclaim CO2 Split System

It’s ultra-efficient even in colder regions and supports flexible scheduling, app control, and high-temperature output.
Areas to Consider:
The only barrier is cost. With pricing upwards of $5,000, this is clearly a premium product. However, the total value—long-term energy savings, customer satisfaction, and minimal maintenance—justifies the investment for many.
Value Verdict:
Reclaim Energy remains the gold standard for hot water heat pump systems in 2025. It’s the go-to option for eco-minded homeowners wanting top-tier efficiency and long-term performance in one of the most trusted packages on the market.
What Makes a Top-Rated Heat Pump in Australia? 2025 Solar Choice Criteria
If you’re looking for the best heat pump hot water systems in Australia, the updated 2025 Solar Choice Scorecard is designed to help you make an informed, confident decision. This independent rating system evaluates heat pumps based on five core categories that reflect what really matters to homeowners: price, company trust, warranty, customer reviews, and functionality.
1. Price: Assessing Upfront Costs and Value
Price is one of the biggest considerations when choosing a hot water heat pump. However, it’s not just about the lowest sticker price — it’s about overall value for money.
Scoring tiers:
- $$$$$ – Over $5,000
- $$$$ – $4,100 to $5,000
- $$$ – $3,300 to $4,100
- $$ – $2,500 to $3,300
- $ – Under $2,500
Higher scores are awarded to more affordable systems, but balanced alongside performance and warranty to determine real value.
2. Company Trust and Reputation
Consumers want to buy from reliable, established brands. This category scores how well-backed the company is and whether it’s likely to be around to support you in future.
Scoring factors include:
- Physical office in Australia (1 point)
- Over 20 staff based locally (1 point)
- Brand history of 5+ years (2 points)
- Broader product offering beyond heat pumps (1 point)
The stronger the company’s foundation, the higher the trust score.
3. Warranty Quality and Transparency
A solid warranty reflects product quality and manufacturer confidence. It also reduces your risk of unexpected repair or replacement costs.
What’s evaluated:
- Warranty period (including parts, tank, and electronics)
- Clarity and fairness of warranty terms
- Ease of making a claim
- Brand credibility and longevity
Systems with comprehensive, long-term warranties and minimal exclusions receive the highest scores.
4. Customer Reviews and Satisfaction
Customer reviews are one of the best indicators of real-world performance. This category scores heat pumps based on both review volume and average star ratings from independent platforms like Solar Choice.
Scoring breakdown:
- 4.5+ stars = 5 points
- 4.25 to 4.49 = 4 points
- 4.0 to 4.24 = 3 points
- 3.5 to 3.99 = 2 points
- 2.5 to 3.49 = 1 point
- Below 2.5 = 0 points
This helps highlight which systems are consistently meeting homeowner expectations over time.
5. Functionality and Performance Features
Heat pump hot water systems are becoming smarter and more efficient. This section scores each product on its ability to meet modern performance standards and user convenience.
Points awarded for features such as:
- Quiet operation (under 45 dBA at 1m)
- Smart controls via Wi-Fi or LCD screen
- Customisable heating schedules (2+ time settings)
- High heating output (over 10W per litre)
The more advanced and user-friendly the system, the higher the functionality score.
How to Use the Scorecard When Comparing Heat Pumps
When comparing the top-rated heat pump hot water systems in 2025, the best approach is to consider your specific priorities:
- Looking for the lowest running costs? Focus on systems with a high efficiency rating and functional control options.
- Need peace of mind? Choose brands with strong local support and a long warranty.
- On a tight budget? Look for lower-cost models that still score well in reliability and reviews.
- Want a smart home integration? Prioritise systems with app control and programmable scheduling.
The Solar Choice scorecard gives you a structured way to compare systems beyond marketing claims — helping you balance performance, affordability, and long-term value.
Limitations of the 2025 Heat Pump Scorecard
While the Solar Choice Heat Pump Scorecard offers a structured and independent comparison, it’s important to understand its limitations when evaluating the best heat pump hot water systems in Australia for your home.
1. Generalisation vs. Personal Preference
Scoring Framework:
The scorecard applies a consistent scoring method across all brands and models. However, what ranks highly overall may not align with your specific household needs, preferences, or local climate conditions.
Functionality Weighting:
The scorecard awards points for features like Wi-Fi connectivity or noise control. Yet, these may be non-essential for some buyers and crucial for others.
2. Pricing & Market Variability
Price Fluctuations:
Heat pump prices can vary widely based on location, installer quotes, seasonal demand, and promotional offers. The price ranges used in the scorecard represent general trends rather than real-time pricing.
Regional Availability:
Not all systems are equally available across all parts of Australia, which may influence what’s actually installable at your property.
3. Customer Review Reliability
Sample Size Variability:
Some brands have hundreds of customer reviews; others have only a handful. While we average the scores where available, a small review base may not reflect broader customer sentiment.
Review Bias:
Public reviews may lean positive or negative depending on customer expectations, service experiences, or isolated issues that aren’t representative of overall quality.
4. Efficiency Comparison Challenges
Inconsistent Testing Standards:
Coefficient of Performance (COP) ratings are influenced by testing conditions. Unfortunately, there’s no industry-wide standard, and some manufacturers publish only best-case performance scenarios.
Disclosure Gaps:
We penalise brands that don’t disclose enough about their testing or whose data lacks transparency — but the gap in testing practices still creates difficulty in apples-to-apples comparisons.
Making the Most of the Solar Choice Heat Pump Scorecard
To ensure the best possible outcome for your investment:
- Cross-Check Sources: Use this scorecard as a starting point. Supplement it with installer advice, customer testimonials, and manufacturer datasheets.
- Assess Your Priorities: Are you budget-driven, efficiency-minded, or tech-focused? Filter results accordingly.
- Stay Informed: Technology evolves fast. Always confirm specs, warranty details, and local rebates with installers before making a final decision.
The scorecard is designed to give you a transparent, third-party framework for comparing heat pump hot water systems — but your final choice should reflect your home’s unique requirements
