What to Look for in a Heat Pump Installer
CEC Accredited Installer
Clean Energy Council accreditation means the installer has completed specific training in renewable energy systems. For heat pumps, this is not strictly mandatory but signals genuine expertise. CEC-accredited installers are required for certain state rebate programs.
Licensed Plumber
In Victoria, heat pump installers must hold a current VBA plumbing licence and be registered with Energy Safe Victoria for any electrical work. Split-system heat pumps also require a licensed electrician.
Heat Pump Specific Experience
Heat pump hot water systems are different from standard electric or gas units. Look for installers who regularly install heat pumps, not just general plumbers doing the occasional heat pump job. They will know the quirks of different brands, understand refrigerant lines, and get the placement right for noise and airflow.
Handles Victorian Energy Upgrades (VEU) Rebate Paperwork
The best installers handle all rebate and certificate paperwork on your behalf. This includes claiming STCs (Small-scale Technology Certificates) at point of sale and processing any Victoria-specific rebates. You should see the rebate discount on your invoice, not have to chase it yourself after installation.
Workmanship Warranty
Your heat pump manufacturer provides a product warranty (typically 5-10 years on the tank, 2-5 years on the compressor). But you also need a separate workmanship warranty from the installer covering the installation itself, such as plumbing connections, mounting, and electrical work. Look for at least 12 months of workmanship cover, ideally longer.
What to Expect During Installation
A typical heat pump hot water installation in Kooyong follows these steps. The whole process usually takes half a day for a straightforward replacement.
Site Assessment
Your installer visits your Kooyong property to assess the existing hot water setup, check plumbing access, measure available space, and evaluate electrical capacity. This determines the right system size and any additional work needed.
System Sizing
Based on your household size, water usage patterns, and roof/ground space, the installer recommends the right tank size and model. Undersizing leads to cold showers. Oversizing wastes money. This is where installer experience matters.
Old System Removal
The existing hot water system is disconnected, drained, and removed. If you are replacing a gas system, the gas supply is safely capped. Your installer should handle disposal of the old unit.
Installation and Plumbing
The new heat pump is positioned (considering noise regulations and airflow requirements), plumbed in, and connected electrically. Split systems require refrigerant line installation between the tank and compressor.
Commissioning and Testing
The system is filled, powered on, and tested. The installer checks for leaks, verifies the heat pump is cycling correctly, sets the timer/boost controls, and walks you through operation.
Rebate Lodgement
Your installer lodges the STC claim and any Victoria rebate paperwork. The STC discount should be applied to your invoice at point of sale. For the Victorian Energy Upgrades (VEU), your installer will process this as part of the job.
What Affects Installation Cost in Kooyong
Installation costs in Kooyong typically range from $4,200 - $6,500 before rebates ($2,600 - $4,900 after). Here is what can push the price up or down.
Metro Pricing
As a metropolitan suburb, Kooyong has good installer competition which helps keep prices in check. Travel costs are minimal and most installers carry stock locally.
Plumbing Complexity
A straightforward like-for-like swap where the new heat pump sits in the same spot is the cheapest option. If plumbing needs to be rerouted, a new concrete pad poured, or the tempering valve relocated, expect $200-$800 extra.
Switchboard Upgrades
Older Kooyong homes may need a switchboard upgrade or dedicated circuit for the heat pump. This can add $300-$600 to the installation if your current board does not have a spare circuit or is not up to current safety standards.
Old System Disposal
Most installers include removal and disposal of your old system in the quoted price. Confirm this upfront. If not included, expect a $50-$150 disposal fee. Gas system removals may cost slightly more due to gas capping requirements.
Gas-to-Electric Conversion
With 89% of Kooyong homes on gas, many installations involve replacing a gas system. This requires a licensed gasfitter to cap the gas supply, which may be included in the quote or cost $100-$300 extra.
Access and Positioning
Heat pumps need adequate airflow around the compressor unit and must meet noise setback requirements from boundary fences. Tight access or the need to crane a unit over a fence adds cost. Discuss placement options during the site assessment.
