When replacing an existing electric or gas hot water system with a STIEBEL ELTRON SHP-O heat pump, you may be eligible to claim VEEC rebates through an accredited provider.

SHP-O 200 Plus | 8 | 7 |

Energy Savings Certificates (NSW Only)
Energy Savings Certificates (ESCs) represent the energy saved from completing a compliant energy-saving activity in New South Wales. Accredited Certificate Providers (ACPs) can create and trade ESCs on the certificate market.
ESCs are available when a STIEBEL ELTRON WWK or SHP-O domestic hot water heat pump replaces:
- an existing electric storage tank or electric instantaneous water heater (D17), or
- an existing gas storage tank or gas instantaneous water heater (D19)
To claim ESCs, your installer must work with an Accredited Certificate Provider (ACP) who manages the creation and trading of certificates. Most installers will coordinate this for you, but it’s important to confirm they are partnered with a registered ACP under the NSW Energy Savings Scheme.
