Smarter Hot Water for an All-Electric Home.

A heat-pump hot-water system draws heat from the surrounding air and transfers it into the water stored inside the tank.

It uses electricity to operate the compressor, fan and controls, but it does not rely only on an electric resistance element to produce heat. This allows a correctly selected heat pump to use less electricity than a conventional electric storage water heater under suitable operating conditions.

Some systems use an integrated design, where the heat pump is mounted on top of the tank. Other systems use a split design with a separate heat-pump unit and storage tank.

The correct size depends on the number of people in the household, shower habits, number of bathrooms, bath usage, peak hot-water demand and how quickly the system can recover.

Tank capacity alone does not determine performance. A system with a smaller tank but faster recovery may perform differently from a larger tank with slower recovery.

Yes. A heat pump uses electricity and can be scheduled to operate during periods when the rooftop solar system is generating electricity.

Running the heat pump during the day can help use more solar generation directly and store the energy as hot water for later use.

The result depends on the solar-system output, heat-pump schedule, household electricity use and the controls available on the selected heat-pump model.

Eligible installations may receive support through the South Australian Retailer Energy Productivity Scheme and applicable federal certificate programs.

The available discount depends on the customer, property, existing water heater, selected equipment and current program requirements.

Eligibility and discount values must be confirmed before installation. Energy Loop can review the available information and show any confirmed discount on the quotation.

Yes. A heat-pump hot-water system may be used to replace an existing gas storage or gas continuous-flow water heater.

The change may require alterations to plumbing, electrical supply, equipment location and the existing gas connection. The complete installation scope should be assessed before selecting the replacement system.

Customers planning to move towards an all-electric home may also wish to consider solar generation, electrical capacity, cooking and space heating as part of the wider plan.

Yes. Heat pumps are commonly used to replace conventional electric storage water heaters.

The new system must still be selected around household hot-water demand, available space, plumbing, electrical requirements and drainage.

The condition and location of the old system do not automatically determine the best location or capacity for the replacement heat pump.

The system requires a suitable location with adequate airflow, access, clearances, drainage and connection to plumbing and electricity.

Integrated heat pumps generally require sufficient open space around the top-mounted heat-pump section. Split systems require suitable positions for both the storage tank and the separate heat-pump unit.

The installation should also consider nearby windows, bedrooms, property boundaries, future servicing access and manufacturer requirements.

Heat pumps contain a fan and compressor, so they produce some operating sound.

The actual sound level varies between brands and models. Correct positioning can reduce the likelihood of disturbance to bedrooms, living areas and neighbouring properties.

Noise should be considered during system selection and site planning rather than after the equipment has been installed.

Heat-pump hot-water systems are designed to operate across a range of outdoor temperatures, but performance and recovery time can vary according to the product and weather conditions.

Some systems use technology designed to maintain stronger performance in colder conditions. The selected system should be suitable for the local climate and the household’s hot-water demand.

Customers should compare operating-temperature information, recovery performance and available backup heating rather than looking only at tank capacity.

Heating and recovery time depend on the system, tank capacity, incoming water temperature, outdoor air temperature, operating mode and the amount of hot water used.

Some systems prioritise efficiency and heat the tank more gradually. Others provide faster recovery or include an electric boost function for periods of higher demand.

Energy Loop considers expected usage and recovery requirements when recommending a system

Some heat-pump systems include a backup or boost element, while others rely primarily on the heat-pump cycle.

A boost function may assist during unusually high hot-water demand, low-temperature conditions or specific operating modes. However, frequent use of direct electric boosting may increase electricity consumption.

The available boost function and operating controls depend on the
selected model.

It is worth considering replacement before the existing system fails completely, particularly if it is ageing, leaking, corroded, unreliable or no longer meeting household demand.

Planning early allows time to compare heat-pump technology, tank size, warranty, installation location, solar scheduling and available rebates.

When a water heater fails suddenly, customers may have fewer product and installation options because restoring hot water becomes urgent.
