iStore Heat Pump Hot Water Installation & Repairs Melbourne

iStore heat pump hot water systems are designed to provide an energy efficient way to heat and store hot water for Melbourne homes. The current range includes 180L and 270L systems using natural R290 refrigerant, giving households different options based on their hot water requirements and available installation space.

Rather than heating water using electricity in the same way as a conventional electric hot water system, an iStore heat pump captures heat from the surrounding air and uses it to heat the water in the storage tank. This can significantly reduce the amount of electricity required to produce hot water.

iStore systems also include programmable timer functions, which can be useful for households with solar panels. By scheduling the system to operate when solar power is available, homeowners may be able to make better use of the electricity their solar system produces.

Choosing the right heat pump involves more than simply selecting a tank size. Household hot water usage, the number of people in the home, available space and the existing hot water system can all affect which system is suitable.

Like other electrical equipment, iStore heat pumps can develop faults or require servicing over time. A system that is producing less hot water, taking longer to heat the tank or using more electricity than usual may need to be inspected.

MJ Air specialises in iStore heat pump hot water repairs and servicing throughout Melbourne’s South Eastern suburbs and the Mornington Peninsula.

The iStore Heat Pump Hot Water Systems

The current iStore Heat Pump Hot Water range includes 180L and 270L models. Both models use natural R290 refrigerant and heat pump technology to transfer heat from the surrounding air into the stored water.

The iStore 180L is designed for smaller households and has a compact 540mm wide footprint. The 270L provides greater storage capacity for larger households and has a 640mm wide footprint.

Both models include timer controls and are designed to operate with significantly less electricity than conventional electric hot water systems. The systems can also be scheduled to operate during periods when solar electricity is available.

iStore systems use components including the fan, evaporator, compressor, condenser coil, storage tank and system controls to heat and store hot water. Like all electrical equipment, individual components may require servicing or repairs over time to maintain performance.

IStore Heat Pump Installation

Installing an iStore heat pump involves more than simply replacing an existing hot water system. The available space, household hot water requirements, existing plumbing and electrical connections all need to be considered when selecting and installing the system.

MJ Air can help Melbourne homeowners choose an iStore system suited to their household and property. The current iStore range includes 180L and 270L models, providing different storage capacities for different levels of hot water demand.

Our technicians can assess your existing hot water system and the proposed installation location before recommending the appropriate iStore model. We can then install the system and ensure the plumbing and electrical connections are completed correctly.

If you are replacing an older electric hot water system, an iStore heat pump may also provide an opportunity to reduce the electricity required to heat your water. The system’s timer can be particularly useful for households with solar panels, allowing heating to be scheduled around solar generation.

MJ Air provides iStore heat pump installation throughout Melbourne’s South Eastern suburbs and the Mornington Peninsula.

Benefits of iStore Heat Pump Hot Water Systems

There are several reasons an iStore heat pump can be an alternative to a conventional electric hot water system.

Lower Energy Use

An iStore uses heat from the surrounding air to heat the water, rather than relying on electricity to generate heat directly. iStore states that its current systems can reduce hot water energy use by up to 70% compared with conventional electric hot water systems. Actual savings will depend on household usage, climate, settings and the existing hot water system.

Works with Solar Power

The built in timer can be used to schedule the heat pump to operate during periods when rooftop solar is generating electricity. This can help households use more of their own solar power to heat and store hot water.

Two Tank Sizes

The current range includes 180L and 270L models. The 180L is designed for smaller households, while the 270L provides greater storage for families and homes with higher hot water demand.

Natural R290 Refrigerant

Current iStore 180L and 270L systems use natural R290 refrigerant. R290 has a very low global warming potential compared with many synthetic refrigerants.

Smart Control and Scheduling

Compatible current models can be monitored and controlled through the iStore app, including temperature settings and heating schedules. This gives homeowners more control over when their hot water is heated.

Five Year Comprehensive Warranty

Current iStore systems come with a five year comprehensive parts and labour warranty, providing additional protection for the system after installation.

Can an iStore heat pump work with solar panels?

Yes. The iStore can be scheduled to heat water during periods when your solar panels are generating electricity. This can help households use more of their own solar power to heat and store hot water.

How long does an iStore take to heat the water?

The iStore 180L typically takes around 4 to 5 hours to fully heat a tank. Actual heating time can vary depending on the ambient temperature, incoming water temperature, settings and household usage.

Can an iStore heat pump be installed outdoors?

Yes. iStore heat pumps are designed for outdoor installation in a suitable location with adequate airflow, drainage and access. Your installer will need to confirm that the proposed location meets the manufacturer’s installation requirements.

Does an iStore heat pump need much maintenance?
