At a Glance: Thermann Split Heat Pump Scores 2.5 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 Thermann Split Heat Pump 250L is priced at more than $5,000 placing it in the highest cost bracket.
- 4/5 – Company Backing and Trustworthiness: Thermann is a well-established brand in Australia with over a decade of operating history and a broader product range beyond heat pumps. The brand is distributed nationally through Reece Plumbing Supplies and has a large installer network across Australia. However, we could not confirm the size of an in-house support team. This earns a strong score for brand credibility.
- 3/5 – Warranty Offer: Thermann offers a solid 10-year tank warranty and 6 years on the heat pump unit. Labour is covered for only 2 years, which is standard but not outstanding. Overall, this warranty provides reasonable peace of mind.
- 0/5 – Customer Reviews: At this time, there are no verified reviews on the Solar Choice platform for this model. Homeowners should consider reaching out to others with experience using Thermann products or asking installers for additional insights. Score 0 points.
- 3/5 Functionality: The unit is quiet at just 37 dBA and delivers strong heating performance with quick hot water recovery times. However, it lacks smart features like app control or flexible scheduling, which are becoming more common in newer systems.
Solarchoice Score = 2.5 out of 5

Thermann Heat Pump Model & Range
Thermann Split Heat Pump
Models & Capacities: Available in 160L, 250L, 315L, and 400L, suitable for households ranging from 2 to 9 people.
Key Features:
- Quiet Operation: Operates at 37 dBA, making it one of the quieter options on the market.
- Eco-Friendly Refrigerant: Uses R744 (CO₂) with a Global Warming Potential (GWP) of 1.
- Flexible Installation: The heat pump unit can be installed up to 5 meters vertically or 15 meters horizontally from the storage tank.
- High Pressure Tolerance: Designed to operate at pressures up to 850 kPa.
- Warranty: 10 years on the tank, 6 years on the heat pump unit, and 2 years on parts and labour.
Thermann Integrated Heat Pump
Models & Capacities: Thermann’s integrated (all-in-one) heat pump models are currently available in 200L and 285L sizes. These systems are typically suited to households of around 2 to 6 people, depending on hot water usage patterns.
Key Features:
- Low-Impact Refrigerant: The integrated heat pump uses R290 refrigerant, which has a significantly lower global warming potential compared with many older refrigerants used in previous generation heat pump systems.
- Smart Control: The system includes a digital controller and app-enabled monitoring, allowing users to manage system operation and adjust settings through different operating modes.
- Operating Modes: Multiple operating modes are available, including Schedule, Holiday, Boost and Rescue, which help homeowners balance energy efficiency and hot water availability.
- All-in-One Design: Because the compressor and storage tank are combined into a single unit, installation can often be simpler than split systems and requires less pipework between components.
- Operating Range: The system is designed to operate across a wide ambient temperature range suitable for most Australian climates.
Thermann Heat Pump Warranty
| Component | Thermann Split Heat Pump (Residential) | Thermann Integrated Heat Pump (Single-Family Home) |
|---|---|---|
| Tank | 10 years | 7 years parts / 3 years labour |
| Heat pump unit / major refrigeration components | 6 years | 3 years parts / 3 years labour |
| Other components | Covered under general warranty terms | 1 year parts / 1 year labour |
| Labour | 2 years parts and labour | Varies by component |
For commercial or non-standard installations, warranty coverage is shorter. Thermann states the Split Heat Pump is covered for 1 year on all components and labour in commercial use, while the Integrated Heat Pump drops to 3 years parts / 1 year labour on the tank and 1 year parts / 1 year labour on other components outside standard single-family residential applications.
In practical terms, the Split Heat Pump has the simpler and stronger warranty for most homeowners, with 10 years on the tank, 6 years on the heat pump unit, and 2 years on parts and labour. The Integrated Heat Pump still offers reasonable cover, but it is less generous and more complex because different parts are covered for different lengths of time. As with most hot water warranties, cover depends on correct installation and compliance with the manufacturer’s conditions. Thermann also notes that separate warranty terms may apply where systems are installed under schemes such as Solar Victoria Solar Homes, VEU, or the NSW ESS.

Cons
- High Upfront Cost: Split systems are priced over $5,000, which may be a barrier for some homeowners.

Is Thermann Hot Water Heat Pumps Worth It?
If you’re a homeowner weighing up whether a Thermann heat pump is right for you, the key takeaway is that Thermann offers a dependable, no-frills solution from an established brand. Their split system stands out for its quiet performance and sturdy design, but it’s priced at the higher end of the market and doesn’t include features like WiFi connectivity or smart scheduling that many newer models now offer.
The Solar Choice scorecard gives Thermann a mid-range rating overall, reflecting a solid warranty, proven company backing, and good – but not exceptional – functionality. The lack of customer reviews is a noticeable gap, which means you’ll need to rely on installer guidance and independent research to assess real-world performance.
In short, Thermann is a solid option if you value brand credibility, quiet operation, and are okay paying more for simplicity. But if you’re looking for cutting-edge tech, extensive consumer feedback, or lower pricing, there are other systems on the market that might be a better fit. Matching the right system to your household’s needs and usage patterns is key – and comparing quotes from multiple suppliers will help ensure you get the best outcome.
