iStore Heat Pump Hot Water Systems for Brisbane, Gold Coast & Major Australian Metros
iStore heat pump hot water systems provide an efficient electric hot-water option for homes upgrading from conventional electric or gas storage systems.
The current Installed Today iStore range is simple: 180L for smaller households and 270L for family-sized demand.
Installed Today supplies iStore heat pumps across supported mainland Australian markets, with supplied and installed options available in eligible Brisbane and Gold Coast service areas.
Current iStore Heat Pump Range
Which iStore Heat Pump Should You Choose?
| iStore Model | Capacity | Household Starting Point | Best Fit |
|---|---|---|---|
| iStore 180L | 180L | Smaller households | Couples, smaller families, units and townhouses |
| iStore 270L | 270L | Standard family demand | Family homes, larger townhouses and rentals |
iStore 180L Heat Pump Hot Water System
The iStore 180L is the compact model in the current range and is designed for smaller households with moderate hot-water demand.
Installed Today currently positions it around 2–4 occupants depending on household usage, with the collection filter identifying it primarily around the 3-person household class.
It can suit apartments, townhouses, smaller homes, rentals and properties upgrading from smaller electric-storage systems.
iStore 270L Heat Pump Hot Water System
The iStore 270L is the family-size model in the current iStore range.
It provides substantially more stored capacity than the 180L and is better suited to family homes, larger townhouses, investment properties and households with stronger daily hot-water demand.
Installed Today currently positions the 270L around 3–6+ occupants depending on usage, while the collection itself identifies it as the main iStore option for roughly five-person households.
180L or 270L iStore?
Choose 180L When
Household occupancy is relatively low, hot-water use is moderate and the property does not need a large family-sized storage tank.
Choose 270L When
Several occupants rely on the system, showers are concentrated into busy periods or the home simply needs greater stored capacity.
Do Not Guess from Litres
Compare peak shower demand, bathrooms, recovery and household habits rather than assuming the larger model is automatically better.
How Does an iStore Heat Pump Heat Water?
iStore heat pumps use air-source heat-pump technology to collect heat from the surrounding air and transfer that energy into stored water.
Electricity still powers the heat-pump components and controls, but the system does not rely solely on direct electric resistance heating during normal heat-pump operation.
Actual electricity use depends on water demand, climate, operating mode, temperature settings and installation conditions.
iStore 180L and 270L Use R290 Refrigerant
Both current iStore models use R290 refrigerant within their heat-pump refrigeration circuit.
Refrigerant type is one part of the product design. Household sizing, recovery, installation position, controls, noise and warranty remain equally important when comparing heat pumps.
iStore 270L Efficiency and Controls
The current iStore 270L product lists a COP of approximately 4.82 under stated test conditions.
COP is a test-based efficiency measure and should not be interpreted as guaranteed year-round household performance.
Ambient temperature, incoming water temperature, operating mode, set-point temperature and household usage all affect real-world energy consumption.
iStore Heat Pumps with Rooftop Solar
Heat-pump hot water can be a useful match for homes with rooftop solar because water heating can often be scheduled for daytime operation.
The iStore 270L includes timer control and is currently promoted with smart solar integration and Wi-Fi-ready control features.
This can help households align more water heating with periods of solar production where the system and household routine allow.
Timer and Smart Control Options
Both current iStore models include electronic controls and timer functionality.
The 270L also includes Wi-Fi-ready app control in its current product specification.
Controls can help manage operating periods, but the best schedule still depends on hot-water demand, tariff arrangements, solar generation and recovery requirements.
How Loud Are iStore Heat Pumps?
Both current models are listed at approximately 46.6dB at 1 metre under stated test conditions.
Heat pumps contain a compressor and fan, so installation position should consider bedrooms, neighbouring properties and outdoor living areas.
Published noise data is useful for comparison but does not account for every installation environment.
iStore 180L vs 270L Physical Size
| Model | Width | Height | Why It Matters |
|---|---|---|---|
| iStore 180L | Approx. 540mm | Approx. 1956mm | Narrower footprint for smaller installations |
| iStore 270L | Approx. 640mm | Approx. 1956mm | Wider tank provides greater stored capacity |
Always confirm current manufacturer dimensions before ordering or preparing an installation location.
Replacing an Electric Hot Water System with iStore
iStore heat pumps are commonly compared when replacing conventional electric-storage hot-water systems.
The 180L can be relevant to smaller 125L–160L electric replacements, while the 270L can be compared where the existing property has a 250L-class family hot-water system.
Heat pumps are not automatically direct physical replacements for electric cylinders. Airflow, drainage, electrical supply, noise and installation clearances also need to be checked.
iStore 180L for Smaller Electric Hot Water Replacements
The 180L can suit households upgrading from smaller conventional electric-storage systems where current hot-water demand remains moderate.
It provides greater nominal storage than many 125L and 160L electric cylinders while remaining considerably smaller than the 270L iStore.
If the old smaller tank regularly ran out of hot water, reassess household demand before automatically choosing the 180L.
iStore 270L for Family Electric Hot Water Replacements
The 270L is the natural iStore comparison for family homes replacing larger electric-storage tanks.
Its capacity makes it particularly relevant to homes moving from approximately 250L electric storage into heat-pump hot water.
Households currently using 315L or 400L tanks should size carefully before reducing nominal stored capacity.
iStore Heat Pump vs Conventional Electric Hot Water
iStore Heat Pump
Uses air-source heat-pump technology for normal water heating and can reduce reliance on direct resistance heating.
Electric Storage
Uses electric resistance elements and can provide a simpler like-for-like replacement where installation simplicity is the main priority.
Main Trade-Off
Heat pumps can reduce hot-water electricity use but require greater consideration of airflow, drainage, noise, controls and installation location.
iStore Heat Pumps Need Suitable Airflow
iStore heat pumps collect heat from surrounding air, so installation position matters.
The appliance needs suitable airflow and manufacturer clearances rather than simply fitting into the same physical footprint as the previous electric tank.
Tight cupboards and poorly ventilated areas should not be assumed suitable without checking the product installation requirements.
iStore Heat Pump Condensate and Drainage
Heat-pump operation can produce condensate, so suitable drainage needs to be considered as part of the installation.
Valve discharge and existing drainage also need to suit the new hot-water system and current installation requirements.
A convenient tank location is not automatically suitable if drainage cannot be arranged correctly.
What to Check Before Ordering an iStore Heat Pump
- 180L or 270L capacity
- Number of occupants
- Peak shower demand
- Existing hot-water size
- Available installation space
- Airflow clearances
- Drainage
- Electrical supply
- Existing valves
- Pipework condition
- Noise-sensitive areas
- Old-unit removal access
Check the Current iStore Warranty for Your Model
Warranty terms can differ between components and models and may include conditions relating to installation, servicing, water quality or other manufacturer requirements.
Check the current warranty documentation for the exact iStore model before purchase rather than relying on a generic brand-wide warranty figure.

iStore Makes the Capacity Decision Simple
The current iStore range provides two clearly different residential options: 180L for smaller household demand and 270L for family-sized demand.
Compare occupants, bathrooms, shower habits, peak demand, tank capacity, recovery, electrical requirements, noise, airflow, drainage, dimensions, controls, warranty and installation position before ordering.
If the 180L is likely to operate close to its limit, choose the 270L or compare the wider heat-pump range rather than undersizing the household hot-water system.
iStore Hot Water System FAQs
Straight answers about iStore 180L and 270L heat pump hot water systems, household sizing, energy efficiency, noise, solar compatibility and installation.
What are the most popular iStore heat pump hot water systems?
Installed Today's current iStore range includes the iStore 180L Heat Pump and the iStore 270L Heat Pump . The 180L is the popular compact option for households of around 3 people, while the 270L is the popular family-size option for around 5 people or homes with higher daily hot water demand.
What is the difference between the iStore 180L and iStore 270L?
The biggest difference is storage capacity and household demand. The iStore 180L has a 180L tank and is best suited to smaller households of around 3 people. The iStore 270L has a larger 270L tank and is better suited to family homes of around 5 people. The 180L is also narrower at approximately 540mm wide, while the 270L is approximately 640mm wide. Both are close to 1956mm high and both use R290 refrigerant.
Is the iStore 180L suitable for 3 people?
Yes. The iStore 180L Heat Pump is Installed Today's recommended iStore size for around 3 people. It can suit apartments, townhouses, smaller homes and households with moderate hot water demand. iStore also describes the model as suitable for roughly 2 to 4 occupants depending on shower length, water use, climate, timer settings and household habits.
Is the iStore 270L suitable for a family of 5?
Yes. The iStore 270L Heat Pump is Installed Today's recommended iStore size for around 5 people. Its larger 270L tank makes it a strong choice for family homes, larger townhouses and households with higher daily hot water demand. iStore describes the system as suitable for roughly 3 to 6 or more occupants depending on shower habits and daily usage.
How big are the iStore 180L and 270L heat pumps?

The larger iStore 270L is approximately 1956mm high and 640mm wide, with a listed weight of around 135kg. The extra 100mm diameter of the 270L should be considered where side access or the existing hot water location is restricted. Both models also need suitable airflow, drainage and service clearances.
Are iStore heat pump hot water systems noisy?
iStore heat pumps are designed for relatively quiet residential operation, but they are not silent because they contain a fan and compressor. Both the iStore 180L and 270L are listed at approximately 46.6 dB at 1 metre under stated test conditions. Installation position still matters, so avoid placing the unit immediately beside bedroom windows, neighbouring bedrooms or narrow echo-prone areas where practical.
Do iStore heat pumps use R290 refrigerant?
Yes. The current iStore 180L and 270L models both use R290 natural refrigerant. R290 has a very low global warming potential compared with many older refrigerants and is increasingly used in modern heat pump hot water systems because it provides strong heat-transfer performance while reducing refrigerant environmental impact.
Does the iStore 270L have Wi-Fi and work with rooftop solar?

Can I replace an electric storage hot water system with an iStore heat pump?
In many cases, yes. The iStore 180L and 270L are commonly considered as energy-efficient replacements for conventional electric storage hot water systems. A heat pump still needs suitable outdoor airflow, drainage, electrical supply, a compliant base, plumbing connections and service access. Changing from electric storage to a heat pump may also require electrical alterations because it is not necessarily the same connection type as the existing system.
Can I buy an iStore heat pump supply only or supplied and installed?
Yes. Choose supply only if you already have an appropriate licensed installer arranged. Supply only includes the iStore heat pump but not installation, valves, disposal, electrical work, pipework changes or drainage alterations. Supplied and installed options are also available in eligible installation areas.
