Local guide
How heat pumps work in Sydney
An air source heat pump in Sydney typically starts around $7,200 installed, including the unit, cylinder, controls and commissioning. A full conversion can cost more where radiators or pipework need upgrading.
Because a heat pump runs at lower flow temperatures than a boiler, the survey is the most important part of the job. Installers measure room-by-room heat loss, check radiator sizes and look at where a hot water cylinder can go — in Sydney that usually decides whether the quote is realistic.
Ask every installer for the modelled running cost at your actual tariff, not just the efficiency figure, and confirm what happens to your existing boiler or heating system once the pump is in.

Local incentives for Sydney homeowners
Federal STC rebate
Small-scale Technology Certificates are deducted from your quote upfront, typically cutting 25–35% off a solar system.
State battery and solar rebates
Victoria, NSW and SA run additional rebate and interest-free loan schemes for solar and battery storage.
Feed-in tariffs
Retailers pay 3c–12c per kWh exported, and some offer higher rates when you have a battery.
Heat Pumps in Sydney: common questions
Do I need to replace my radiators?
Not always. Many homes only need two or three oversized radiators swapped, and the heat loss survey shows exactly which ones.
Is a heat pump noisy?
Modern units run at a similar level to a fridge from a few metres away. Siting matters, so installers position the unit away from bedrooms and boundaries.
Can I keep my boiler as backup?
Some systems are designed as hybrids, but most grant schemes require the boiler to be removed or decommissioned, so confirm this before signing.
How much does solar cost in Australia?
A 6.6kW system typically costs $5,000–$8,000 after the STC rebate, and saves $1,000–$1,800 a year depending on self-consumption.
Is a battery worth it in Australia?
With state rebates and rising evening tariffs, a 10kWh battery now typically pays back in 6–9 years in Victoria and South Australia.
What does CEC accredited mean?
Clean Energy Council accreditation is required for the federal rebate and confirms the installer has completed the required design and safety training.
Can I add a heat pump hot water system?
Yes. Heat pump hot water is usually the cheapest way to cut a gas bill, and it qualifies for STC credits too.
