iStore – Company Background
iStore is an Australian owned business who have been developing and wholesaling heat pump hot water systems. The company was established in 2019 as a sub-brand and trading name of Solargain PV who are a national solar and hot water installation company.
The company has recently expanded into solar inverters and solar battery solutions which will be manufactured by Huawei. They are also expected to add EV Chargers to their range later this year.
Solargain are based in Perth, but have offices all across the country.
iStore Model Range in Australia
There are 2 heat pump hot water systems offer by iStore in Australia. The main difference between the two is the capacity of the hot water tank.
iStore 180L
The 180 litre option is typically suitable 2-3 person households, based on an assumed usage of around 50 litres of hot water per person per day.
The product is an ‘all-in-one’ system meaning that the compressor sits above the hot water tank in a tall cylindrical design. The iStore 180L is 1955mm tall and has a diameter of 540mm.
The product datasheet suggests that the compressor will use 0.5kW when active and that a typical cycle requires 3-4 hours. This means the overall energy usage per day is expected to be around 1.5kWh to 2kWh.
The overall product weighs 93kg and is recommended to be installed on a concrete slab. Given the size and weight, consideration should be given to how the product will be transported to the install location.
iStore 270L
The larger 270 litre option is best suited to 3-6 person households under an assumption of approximately 50 litres of hot water usage per person per day. Very large households, or multi dwelling properties servicing from a single tank, may need to consider a commercial hot water heat pump system.
This solution has the same height of 1955mm as the 180L unit, however has a slightly larger diameter of 640mm.
With the larger tank, iStore advise that the compressor will use twice as much energy (1kW) when in use. With the same cycle time this means the expected energy usage may be 3kWh to 4kWh with this unit. Along with the higher running costs, the upfront cost of the 270L model is around $300 more than the 180L model.

iStore Heat Pumps – Key Features
The are some key features of iStores heat pump hot water products that can be advantageous to homeowners.
Back Up Heating Element
Along with the air to heat compressor technology, the iStore heat pumps also come with a traditional heating element. In the various operating modes available with the iStore solution the element can be used to accelerate the water heating process.
LCD Touch Screen
The iStore can be configured through a LCD touch screen on the system. This can be used to set timers and alternate through the various operation modes to ensure you minimising the energy costs and optimising the use of the product. We recommend you hang on to the user manual and your installers phone number as altering the settings can be a bit tricky.

iStore Warranty for Australian Customers
The warranty offer is one area where iStore have attempted to provide a point of difference against alternative models. iStore offer a ‘5-year comprehensive warranty’ on their products.
This includes a 5 year parts and labour warranty on:
- The water tank
- Refrigeration via the compressor technology
- Electrical controller and sensor leads
However, the warranty documents stipulates that there is only a 1-year parts and labour warranty on
- Sacrificial anode
- PTR valve
- Air filters
- Other consumable items including thermostat and heating element
The items that miss out on the 5-year warranty are typically lower value and normally excluded from the longer warranty periods with other hot water systems.
The labour is only included in the warranty if you are within 30km of the closest iStore branch or Authorised Distributor, otherwise you will need to pay additional freight and travel costs.
The iStore warranty document does not mention the entity that provides it, so we assume that the warranty provider is Solargain PV Pty Ltd and not the original manufacturer of the products.
They do have a help line customers can call on 1300 515 640
The full terms and conditions of the warranty are located in the iStore User Manual.
