Frequently Asked Questions

The basics

What is an iStore?

iStore – Air to Energy systems utilise the latest compressor technology to naturally extract heat energy from the air and store it in the form of hot water for later use. Designed in Australia for Australian conditions, the iStore is one of the most cost-effective dual-purpose storage solutions available.

How does the iStore work?

The iStore utilises refrigeration technology which is an incredibly efficient form of producing heating capacity since the first refrigerant gas was developed way back in 1928. The process is very similar to pumping up a bicycle tyre with a hand held pump; the more compression and pressure when using a bicycle tyre pump, the hotter the pump gets. This is essentially the same process as the iStore’s Hitachi compressor in action – creating heat from compression and transferring the thermal energy around the tank to heat the water inside the fully insulated cylinder.

Why choose an iStore?

For Australian households and businesses, the heating of hot water is the largest contributor of greenhouse gas emissions and energy costs. The iStore runs at an incredible 400% efficiency, and when synced with Solar Roof Solar Power, the hot water heating costs can be as low as 11 cents per day

Operation
Will the iStore ever run out of hot water?

No – Fully customisable, the iStore incorporates 4 modes to suit every hot water application. From small households to large hot water demands, one iStore can produce over 2,500 litres of hot water in a 24hr period.

Will my system work in overcast conditions?

Of course – the iStore is not reliant on the sun shining. Extracting energy from the surrounding air, the iStore will provide reliable hot water day and night, all year round.

Is the iStore technology safe?

Compared to conventional gas and electric resistive hot water systems, the iStore surpasses the latest Australian Standards for safety. With an incredibly low power draw when in operation (less than a household kettle), the iStore seamlessly integrates with existing electrical infrastructure in any Australian home or business.

How noisy is the compressor?

The team behind iStore invested over 10,000 man hours ensuring the compressor would be as quiet as possible, without sacrificing efficiency. The iStore has been independently tested to 46.6dB at 1m. It’s an amazing achievement and we’re proud to say we have one of the quietest systems available on the market.

Will my system be covered by home building insurance?

Of course – checking with your insurance company is the first port of call. iStore recommends that your insurance company is notified and listed on your policy. We also suggest to check whether you have fusion protection in case of power surges.

Performance and Savings

How much money can I save?

By installing an iStore, you can save up to $1500 per year.

How much pollution can I save?

Installing an iStore is the equivalent of removing 4 tonnes worth of CO₂ every year!

How long before my system pays itself back?

The best return on investment can be under 2 years when factoring in the replacement / purchase cost of a traditional hot water system.

Are government incentives and rebates still available?

Yes. Depending on your residing state in Australia, customers replacing existing traditional hot water systems may be eligible for $800 to $3000 off their system cost!

Installation

Does the iStore need to be installed on the ground?

The most common installation location is on the ground, located outside the home. Custom solutions for tight / elevated areas can be designed, however please contact an iStore specialist to discuss your needs.

How much space will the iStore take up?

The 270L all-in-one iStore will require approximately 0.7m in width x 2.1m height.

Can the iStore be installed indoors?

Yes – the iStore can in fact be installed indoors as the refrigerant used is non-flammable and safe to be installed indoors. Provision for adequate fresh air to unit location shall be provided. Contact iStore to discuss your site-specific needs.

Will I be without hot water for long during installation?

Typically, an installation of the iStore will take between 2-3 hours to complete. In almost all installation scenarios you will have hot water again the same evening of installation.

Can I replace an existing gas or electric hot water system?

Yes – the iStore is an ideal replacement for existing gas or electric hot water systems. In fact, installing an iStore when replacing existing hot water systems takes about the same time as installing a traditional gas or electric hot water system.

Post Installation
Is my iStore easy to maintain?

Yes – the iStore is very easy to maintain. After your iStore is installed and commissioned, maintenance required is very minimal.

How often should I have it serviced?

iStore recommends that a 5 year service be conducted to ensure the system is working at maximum efficiency.
