Factors to Consider When Choosing a Heat Pump Hot Water System
Selecting an appropriate heat pump hot water system for your home involves a thoughtful analysis of several crucial factors. These include:
-
Your household size and hot water usage
-
Your region’s climate
-
Noise levels and system placement
-
Energy efficiency and cost savings
We’ll further explore these factors to assist you in making an informed decision.
Household Size and Hot Water Usage
One of the most crucial factors to consider when choosing a heat pump hot water system is your household size and hot water usage. The average hot water usage for households can be calculated by using online calculators that take into account factors such as the number of people living in the home, total number of showers and baths taken, and the average duration of these showers. It is generally recommended to allocate 50L of hot water per person per day, along with an additional 50L to ensure there is enough hot water for all residents.
For instance, a medium-sized household consisting of 3-6 people would be best suited with a heat pump hot water system with a capacity of around 210 litres. However, for larger households, a system with a capacity of 300-315 litres would be more appropriate. It’s crucial to choose a system that matches your household’s needs to avoid insufficient hot water or paying for unused capacity.
Climate Compatibility
Another important factor to consider when choosing a heat pump hot water system is climate compatibility. Heat pump hot water systems are most efficient in moderate to warm climates, where the optimal outside air temperature range is between 7°C to 29°C. However, they are capable of operating in colder climates, debunking the misconception that they are only suitable for mild weather.
In fact, specific models of heat pump hot water systems are designed to uphold high efficiency in cold climates, guaranteeing effective performance even in low temperatures. Moreover, the performance of a heat pump hot water system can be significantly improved by selecting a system with a high COP rating and adding insulation to the hot water cylinder. These measures ensure superior performance across a variety of climate conditions.
Noise Levels and Placement
Noise levels and system placement are also important factors to consider when choosing a heat pump hot water system. The typical noise level of a heat pump hot water system ranges from approximately 40 to 60 dBA, which is comparable to the sound of a whispered conversation or an average conversation. Therefore, the placement of a heat pump hot water system plays a crucial role in mitigating noise levels.
By installing the system in areas such as a garage or utility room, perceived noise levels can be significantly reduced, preventing disturbances. Furthermore, using soundproofing methods, such as:
-
sound blankets
-
acoustic panels
-
weatherstripping
-
double-glazed windows
can also help reduce noise.
It’s also worth noting that the noise levels of the top heat pump hot water systems of 2024 are relatively low, with the iStore 270L Heat Pump Water Heater and the Rheem Ambiheat 270 operating at around 48 dB(A), and the Stiebel Eltron WWK302 series featuring a lower noise level at 45dBA.
Energy Efficiency and Cost Savings
Energy efficiency and cost savings are perhaps the most critical factors to consider when choosing a heat pump hot water system. Heat pump hot water systems are significantly more energy efficient than traditional water heating systems, typically consuming around 60 to 75% less electricity. This increased efficiency translates into significant energy bill savings, making heat pump hot water systems a cost-effective choice for many households.
To give you an idea of the potential savings, consider the energy efficiency ratings of our top picks. The iStore 270L Heat Pump Water Heater boasts a COP of 4, significantly reducing hot water heating consumption compared to conventional systems.
The Rheem Ambiheat 270 provides energy savings ranging from 64% to 75% in different zones for hot water energy consumption. And the Stiebel Eltron WWK302 Series can save up to 74% on hot water energy use compared to traditional water heaters. These numbers clearly show that investing in a heat pump hot water system can lead to substantial savings on your energy bills.
Installation and Maintenance Tips
The installation of a heat pump hot water system in your home is a serious undertaking. Having a certified professional handle the installation is crucial due to the specific technical knowledge and experience required to ensure it is done correctly. A certified professional is equipped to handle the various steps involved, including:
-

Financial Incentives and Rebates
Although heat pump hot water systems might have a higher initial cost compared to traditional water heaters, there are several government incentives and rebates that can considerably alleviate the installation costs. These include:
-
Solar hot water rebates, with federal and state support
-
Up to $1000 available for Victorian households through the Solar Homes Program
-
Up to $2000 from the South Australian Government for qualifying installations
To qualify for these rebates, individuals must adhere to the specific program’s set criteria, which usually involve property ownership and occupancy, possessing an eligible heat pump system, and meeting certain energy provider guidelines. For instance, the iStore 270L Heat Pump Water Heater can receive up to a $1,080 incentive from the Australian Federal Government Clean Energy Regulator, and the Rheem Ambiheat 270 is eligible for Federal Government STCs and other renewable energy incentives. These incentives and rebates can greatly offset the initial costs of installing a heat pump hot water system, making these systems a cost-effective solution in the long run.
Integrating Renewable Energy Sources
Beyond their intrinsic energy efficiency, the performance of heat pump hot water systems can be enhanced by incorporating renewable energy sources, such as Solar PV systems, and leveraging off-peak electricity tariffs. The process of integrating a heat pump hot water system with Solar PV systems involves connecting the heat pump to the solar system and using a smart controller to optimize solar energy use for heating. This combination allows for significant energy savings as solar panels reduce the amount of energy required to power the heat pump, enhancing overall efficiency and lowering the carbon footprint.
Off-peak electricity tariffs are another way to boost the efficiency and cost-effectiveness of your heat pump hot water system. These tariffs offer reduced electricity prices during times of lower demand, such as at night or on weekends. Heat pump hot water systems can benefit from these tariffs by accessing up to 18 hours of discounted power at rates much lower than standard domestic tariffs. The reduced rate, which can be around 60% less than usual tariffs, leads to lower energy bills and thus, enhances the overall affordability of operating heat pump hot water systems.
Expert Advice: Consulting a Plumber
Selecting a heat pump hot water system is a considerable decision, hence the importance of obtaining expert advice. Consulting a knowledgeable plumber can provide valuable insights and guidance. A professional plumber has the necessary experience and expertise to recommend the most suitable system for your home. They consider various factors, such as:
