iStore Heat Pump Hot Water Systems in Ellenbrook
Looking for a more energy-efficient way to heat your home’s water?
Banrock Plumbing supplies and installs iStore heat pump hot water systems throughout Ellenbrook, Aveley, The Vines and surrounding suburbs.
iStore heat pumps use energy from the surrounding air to heat water, offering an efficient alternative to conventional electric storage and gas hot water systems.
We specialise in iStore installations and can help you choose a suitable system for your household, understand the installation requirements and explore potential running-cost savings.
Whether you’re replacing an ageing hot water system or planning to move away from gas, we’ll provide practical advice and clear pricing information to help you make an informed decision.

Why Choose an iStore Heat Pump?
An iStore heat pump provides an energy-efficient way to heat your home’s water without relying on traditional electric heating elements for everyday operation.
Rather than generating heat directly, the system extracts warmth from the surrounding air and transfers it into the water stored inside its insulated tank.
This technology can substantially reduce the electricity required for water heating, making iStore an attractive option for homeowners looking to lower energy consumption and running costs.
With 180L and 270L models available, there’s a suitable option for many different household sizes and hot water requirements.
Lower Hot Water Running Costs
Heating water can account for a substantial portion of household energy consumption.
iStore heat pumps use electricity to transfer heat from the surrounding air rather than relying entirely on conventional electric resistance heating.
This can significantly reduce water-heating energy consumption compared with traditional electric storage systems.
Actual savings depend on your existing hot water system, electricity tariffs, household usage and installation conditions.
Make Better Use of Rooftop Solar
If your home has solar panels, an iStore heat pump can help you make better use of the electricity they generate.
Programmable operating times allow the system to heat water during periods of solar production, reducing reliance on electricity purchased from the grid.
The insulated storage tank then retains heated water for use later in the day.
You don’t need rooftop solar to benefit from a heat pump, but combining the two can offer additional running-cost advantages.
Suitable for Perth’s Climate
Heat pumps draw thermal energy from the surrounding air, making them well suited to many residential installations in Perth.
iStore systems are designed to operate across a range of ambient temperatures, providing efficient hot water heating throughout the year.
Performance varies with weather conditions, installation location and household demand, so selecting the correct system and positioning it appropriately are important.
An Alternative to Gas Hot Water
For homeowners considering a move away from natural gas, an iStore heat pump can replace an existing gas storage hot water system.
This removes the need to use gas for water heating and can form part of a broader transition towards an all-electric home.
Banrock Plumbing can assess your existing installation, explain the gas disconnection requirements and help you understand whether a heat pump is a suitable replacement.
iStore 180L vs 270L — Which Size Is Right for Your Home?
Choosing the right heat pump capacity is important for reliable hot water and efficient operation.
iStore offers two popular residential models: the compact 180L and the larger 270L.
Both use heat pump technology to efficiently heat and store water, but they differ in storage capacity and heating performance.
The best choice depends on your household size, showering habits, daily hot water consumption and available installation space.

iStore 180L Heat Pump
The iStore 180L is designed for smaller households with modest to moderate hot water requirements.
Its compact footprint makes it particularly attractive where installation space is limited.
With 180 litres of stored hot water, it can suit households of approximately two to four people, depending on usage.
We recommend considering daily showering habits, bathroom fixtures and expected peak demand before choosing the smaller model.

iStore 270L Heat Pump
The iStore 270L provides greater hot water storage and heating capacity, making it a popular choice for family households.
Its larger tank is particularly useful where multiple people shower throughout the day or hot water demand is relatively high.
The 270L is generally suited to households of approximately three to six or more people, depending on consumption.
For homes with higher demand, the additional capacity provides more flexibility during busy periods.
| Feature | iStore 180L | iStore 270L |
| Storage capacity | 180 litres | 270 litres |
| Typical household | 2-4 people | 3-6+ people |
| Best suited to | Smaller Households | Familes and higher demand |
| Heating performance | Lower output | Higher output |
| Solar-friendly operation | Yes | Yes |
| Refrigerant (current models) | R290 | R290 |
Indicative guidance based on current iStore manufacturer information. Household suitability varies with usage.
Should You Choose the Larger iStore?
A larger tank isn’t automatically better for every household, but sufficient hot water storage is particularly important when choosing a heat pump.
Unlike conventional electric storage systems, heat pumps generally take longer to recover after large amounts of hot water have been used.
The larger iStore 270L offers additional storage and higher heating output, which may be worthwhile for busy households or those wanting greater flexibility.
We’ll consider your existing hot water system, household usage and installation conditions before recommending the appropriate model.
Our aim is to provide enough hot water for your needs without unnecessarily increasing the cost of your installation.
Replacing Your Existing Hot Water System With an iStore
An iStore heat pump can replace many existing gas, electric and solar hot water systems.
However, the installation requirements depend on the type of system being removed, its location and the property’s existing plumbing and electrical arrangements.
Banrock Plumbing assesses these factors before recommending a replacement. We’ll explain what’s involved, identify any additional work and help you choose a suitable installation location.
Replacing Gas Storage Hot Water
Upgrading from gas storage to an iStore heat pump can reduce household reliance on natural gas.
The installation generally involves removing the existing storage system, adapting the plumbing connections and safely disconnecting the redundant gas supply to the appliance.
A suitable electrical connection is also required.
If you’re planning to eliminate natural gas entirely, we can discuss the additional gas abolishment steps and what you’ll need to arrange through your gas retailer.
Replacing Electric Storage Hot Water
An iStore heat pump can be an efficient replacement for a conventional electric storage water heater.
The existing tank is removed, and the plumbing is adapted to accommodate the new system.
Unlike many traditional electric storage units, suitable iStore models can operate through a compatible power outlet rather than requiring a hardwired connection.
Electrical work, including disconnecting the existing hardwired unit and providing a suitable supply for the heat pump, must be completed by a licensed electrician where required.
Replacing Solar Hot Water
An ageing or unsuitable solar hot water system may also be replaced with an iStore heat pump.
This can remove the need for solar thermal collectors and their associated plumbing, while allowing the new system to operate independently of the old solar hot water installation.
The work required depends on whether your existing system is roof-mounted, split-system or gas-boosted.
We’ll assess suitable replacements and identify any solar-system removal or specialist work that needs to be arranged.
What Does an iStore Installation Require?
Before installing an iStore heat pump, we consider several important factors:
- Location and space: The unit needs a suitable position with adequate airflow and access for servicing.
- Plumbing connections: Existing pipework may need alterations to suit the new system.
- Electrical supply: A suitable power connection is required, with any necessary electrical work completed by a licensed electrician.
- Drainage: The installation needs appropriate drainage for relief valve discharge and condensate.
- Removal of the old system: We’ll discuss removal and disposal requirements, including any additional work associated with existing solar installations.
We’ll explain the installation requirements and any additional costs before proceeding with your replacement.
iStore Heat Pump Installation Costs & Incentives
The cost of installing an iStore heat pump depends on the model selected, your existing hot water system and the work required at your property.
A straightforward replacement may require relatively minor changes to the existing plumbing. Other installations can involve electrical work, relocating the system or removing older equipment.
Banrock Plumbing provides clear pricing information based on your installation requirements, so you understand what’s included before proceeding.
Eligible iStore installations can also benefit from Australian Government incentives that reduce the upfront purchase cost.
What’s Included in a Typical Installation?
A standard iStore replacement generally includes:
- Supply of the selected iStore heat pump.
- Removal of the existing hot water unit where practical.
- Installation of the new system and necessary plumbing connections.
- Required plumbing valves and fittings.
- Connection to suitable existing drainage arrangements.
- Testing and commissioning of the new system.
- Explanation of basic operation and maintenance.
- Removal of normal installation rubbish.
We’ll confirm the exact inclusions when preparing your quotation.
What Can Increase the Cost?
Some properties require additional work beyond a straightforward replacement.

Eligible iStore heat pump installations can qualify for Small-scale Technology Certificates under the Australian Government’s Small-scale Renewable Energy Scheme.
These certificates have a financial value that can help reduce the upfront cost of installing an approved heat pump hot water system.
Rather than managing the certificates yourself, you can generally assign them to a registered agent and receive their value as a discount on the installation price.
The available discount depends on the eligible model, installation date, location and current certificate value.
We’ll explain the applicable STC discount when preparing your quotation, so you can see how it affects the final installed price.
Are Other Heat Pump Rebates Available in WA?
Heat pump incentives vary between Australian states and territories, and eligibility requirements can change.
In Western Australia, the federal STC incentive is an important consideration when calculating the installed price of an eligible iStore system.
Any additional rebate or assistance must be confirmed against the programs available at the time of installation.
We’ll explain which incentives apply to your proposed installation and provide pricing that accounts for any eligible discounts we arrange.
