iStore 270L R290 Heat Pump Hot Water System
More hot water capacity for busy Australian households. The iStore 270L combines a family-sized storage cylinder, energy-efficient air-source heat pump and timer controls in one integrated unit. Buy the iStore PASHW015-270LD-FL02-R290 supply only from Hot Water Outlet, with delivery available to selected metropolitan locations.
HWO supplies the unit but does not install hot water systems directly. You can engage your own licensed trades or enquire about assistance obtaining independent installation quotes after purchase where available.
Why choose the iStore 270L?
The iStore 270L heat pump water heater takes heat energy from the surrounding air and moves it into a 270-litre storage tank. Compared with a conventional resistance-element storage heater, this can lower the electricity needed to produce household hot water in suitable conditions. It is designed for homes seeking efficient, dependable storage capacity rather than instantaneous continuous-flow heating.
iStore markets the 270L capacity to families of roughly 3–6+ people. The correct size still depends on how much water your household uses, shower length, local incoming-water temperature, the heating schedule and whether baths or multiple outlets are used close together.

Heat pump efficiency and everyday running costs
Energy-efficient water heating
Rather than generating all its heat directly from an electric element, the iStore uses a refrigeration cycle to collect ambient heat and transfer it into the cylinder. iStore states a COP of approximately 4.82 at 20°C ambient when heating the tank from 15°C to 60°C under specified test conditions.
That value is a laboratory-rated efficiency measure, not a year-round guarantee. Outdoor air temperature, hot water draw-offs, heat loss, auxiliary heating and operation settings affect real usage.
Schedule around rooftop solar
The built-in timer can be used to shift heating into daytime periods when a suitable home solar PV system is generating electricity. This can reduce grid energy purchased for hot water where sufficient solar generation is available.
Solar use is based on timing and the home's electrical setup. It does not mean the heat pump itself contains a battery or guarantees automatic surplus-solar diversion.
Wi-Fi and smart control: verify the exact version
iStore promotes Wi-Fi and app features for compatible 270L heat pumps, including remote monitoring and scheduling. However, the manufacturer states that Wi-Fi availability depends on the specific model and serial number. This product description does not guarantee Wi-Fi hardware, remote temperature changes or performance tracking for every unit bearing the broader 270L product name.
Built-in LCD and timer operation are described in the R290 user documentation. Before ordering, ask HWO to confirm whether the particular unit being supplied supports the iStore app and which features are included.
Choosing the right location and capacity
Where the iStore 270L makes sense
- Family homes replacing conventional electric storage systems.
- Larger townhouses where 270L storage suits daily usage.
- Properties with space for an upright integrated heat pump and required airflow.
- Homes able to schedule heating to match daytime solar PV generation.
- Owners who prefer to engage their own licensed plumber and electrician.
What to check before buying
- Physical dimensions, access route, lifting needs and the weight of a filled tank.
- Manufacturer-required ventilation, service clearances and noise-sensitive boundaries.
- Compliant condensate and relief-valve drainage.
- Correct plumbing, tempering, pressure control and electrical circuit.
- Any tariff, solar timer and Wi-Fi version requirements.
Outdoor location is generally preferred. The 2026 iStore manual also discusses indoor locations only where substantial fresh-air requirements can be met (1000m³/h for the 270L), along with other restrictions. This is not a typical unventilated cupboard appliance; any indoor installation must be assessed by appropriately licensed installers against the current manual and regulations.
iStore 180L vs 270L heat pump — which size?
| iStore 180L | More compact nominal storage, marketed for smaller households of approximately 2–4 people. Suitable where daily demand and installation space favour a smaller unit. |
|---|---|
| iStore 270L | 90L more nominal storage than the 180L; marketed for approximately 3–6+ people and higher everyday demand. Larger footprint and more demanding lifting/clearance planning. |
Neither model's litres alone determine how many showers you can take. Actual delivery depends on thermostat settings, incoming water temperature, tempering, water flow, stored heat and reheating availability.

Tempering Valve and Element Information
*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.
If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.
Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.
Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.
1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.
This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.
Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.
**Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.
A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.
If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.
If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.
Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.
It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
