What rebates can I claim on a iStore heat pump?
Every iStore model attracts federal Small-scale Technology Certificates (STCs) worth $560-$680 at point of sale. On top of STCs, Victorian households can stack the Solar Victoria Hot Water Rebate ($1,000-$1,400) and Victorian Energy Upgrades discount ($500-$2,000) to reach up to $2,700 in rebates. NSW (Energy Savings Scheme), SA (REPS), and ACT (Sustainable Household Scheme) have their own state-level top-ups.

Solar Victoria's rebate is the one worth going after on top, and your installer drives it. They lodge it with your quote, you add ID and proof of income, and it comes off your invoice on approval.
What is the warranty on a iStore heat pump?
iStore backs its tanks with a 5-year warranty and the compressor with 5 years. Workmanship cover for the install itself comes from your installer separately and should be at least 12 months. Warranty claims require the system to have been installed by a licensed plumber and serviced according to the manual.
How efficient is a iStore heat pump?
The iStore 270L runs at COP 3.2 (every 1 kWh of electricity input produces 3.2 kWh of heat output). Annual running cost is around $400 for a 3-5 person household, compared to roughly $700/year for gas storage and $900/year for old-school electric resistive storage.
How long does a iStore heat pump last?
Modern hot water heat pumps last 12-15 years on average in Australian conditions. Tank life depends on water hardness (sacrificial anode replacement every 5 years extends life). Compressor life is the limiting factor and typically matches or exceeds the warranty period when the unit is correctly sized and serviced.
