The two rebates — and they stack
Adelaide homeowners have two independent rebate pathways that work together:
- REPS – South Australia's state scheme. The discount lands directly on your installation invoice; no forms.
- STCs – a federal incentive under the Renewable Energy Target. Your installer assigns the certificates and passes the value back as an upfront discount.
Because one is state and one is federal, you can claim both.
| Incentive | Level | Typical value | How it's claimed |
|---|---|---|---|
| REPS | State (SA) | $500–$1,000 | Applied by installer |
| STCs | Federal | ~$600–$700 | Discount at point of sale |
How much you can save
A worked example on a popular system:
| Cost component | Amount |
|---|---|
| Reclaim CO2 heat pump, 250 L (installed) | ~$8,300 |
| REPS discount | −$700 |
| STC discount (Zone 3) | −$700 |
| Your out-of-pocket | ~$6,900 |
That's over $1,000 in combined rebates applied upfront. A heat pump can also cut your water-heating energy use by up to 70%, most households save $500–$900 a year, so the system can pay for itself in under five years.
