iStore in Brisbane - Frequently Asked Questions

How much does a heat pump hot water system cost in Brisbane?
A heat pump hot water system in Brisbane costs between $2,400 and $4,600 fully installed after all available rebates. Before rebates, expect to pay $3,600 to $5,800. The final price depends on the brand, tank size, and complexity of your installation.
What rebates are available for heat pump hot water in Brisbane?
Brisbane residents can access federal Small-scale Technology Certificates (STCs) worth $500-$700 as a point-of-sale discount. These rebates are typically applied by your installer at the point of sale.
Are heat pumps efficient in Brisbane's climate?
Brisbane has a warm subtropical climate with mild winters. Heat pumps operate at peak efficiency in this climate zone. With warm ambient temperatures year-round, expect COP ratings close to or exceeding manufacturer specifications. Running costs will be at the lower end of estimates. A typical household of 3-4 people will spend $200-$400 per year running a heat pump, compared to $800-$1,200 for gas or $1,200-$1,800 for electric storage.
How long does a heat pump installation take in Brisbane?
A standard heat pump hot water installation in Brisbane takes 3-5 hours for a straightforward replacement. If you're converting from gas, it may take a full day as the installer needs to connect new electrical circuits and potentially modify plumbing. Metro installers typically have availability within 1-2 weeks.
What size heat pump do I need for my Brisbane home?
For Brisbane in climate zone 3: 1-2 people need a 150-170L tank, 3-4 people need a 250-315L tank, and 5+ people should consider a 315-400L tank. Your warmer climate means the heat pump recovers quickly, so standard sizing works well.
Which heat pump brand is best for Brisbane?
In Brisbane's warm climate (zone 3), all heat pump brands perform excellently. Budget models like iStore and Midea deliver strong COP ratings year-round in warm conditions, making them excellent value. If budget allows, Daikin offers the best warranty (10 years parts and labour) and Rinnai's AR series is Australian-made (qualifying for the higher VIC rebate tier).
