If you’re comparing heat pump hot water systems, you’ve probably noticed the prices vary quite a bit between brands and suppliers. So what should you realistically expect to pay, and what’s driving the difference? Here’s a clear breakdown.
What Affects the Price of a Heat Pump System?
The cost of a heat pump hot water system depends primarily on the tank size, the efficiency rating of the heat pump unit, the brand, and the complexity of installation at your property.
Larger households generally need a bigger tank to keep up with hot water demand, and tank size is one of the more significant cost drivers. Higher-efficiency units, which use less electricity per litre of hot water produced, also tend to sit at a higher price point but pay that difference back over time through lower running costs.
Typical Price Range
As a general guide, heat pump hot water systems for an average Perth household typically range from a few thousand dollars for a standard residential unit, up to a higher figure for premium or larger-capacity systems. Installation is usually quoted separately and varies depending on your home’s plumbing and electrical setup.
It’s worth getting quotes from a couple of suppliers to get a feel for the market, but be wary of choosing purely on price — the cheapest unit isn’t always the most cost-effective once you factor in efficiency and longevity.
Don’t Forget the Rebates
One of the biggest factors in the actual out-of-pocket cost is the available government incentive through Small-scale Technology Certificates (STCs). These can meaningfully reduce the upfront price of a heat pump system. We’ve covered the available rebates on hot water systems in more detail separately — it’s worth understanding what applies to your situation before comparing final prices between suppliers.
How Heat Pump Cost Compares to Running Cost Savings
While the upfront cost of a heat pump is higher than a basic electric storage system, the running cost savings are substantial — typically 60 to 75 percent less electricity used for heating water compared to a standard system. For most Perth households, this means the price difference is recovered through energy savings within a few years, after which the heat pump is genuinely saving you money every quarter.
What’s Included in a Typical Quote?
A proper quote should include the unit itself, installation, removal and disposal of your existing system, any electrical work required, and clarity on warranty terms. Make sure you’re comparing quotes that include the same scope of work — a quote that excludes installation or disposal will look cheaper but isn’t an accurate comparison.
Is It Worth the Investment?
For most Perth families replacing an ageing electric or gas system, a heat pump hot water system represents a sound long-term investment — particularly once available rebates are factored in and weighed against years of lower running costs.
