Federal Government Grants - Small-Scale Technology Certificate (STC’s)

  • Enviroflo’s innovative design allows it to be eligible for Grants through the Federal Government’s Small-Scale Renewable Energy Scheme, generously covering a proportion of the up-front costs of purchasing and installing the system.
  • These grants are called Small-Scale Technology Certificates (STCs) and are offered based on how sustainable a hot water system is.
  • Your STC rebate value will depend on your installation location, see the map above for your geographic zone locations.

State Government Grants

Victoria

  • For Victorian consumers there are additional rebates available for replacing inefficient hot water systems with Heat Pumps.
  • Victorian Energy Efficiency Certificates (VEECs) plus a Solar Victoria rebate are offered for eligible installations on top of the Federal STC grants - making the conversion to a Rinnai Enviroflo Heat Pump the obvious low-cost choice.

New South Wales

  • For New South Wales consumers there are additional rebates available for replacing inefficient hot water systems with Heat Pumps.
  • Energy Savings Certificates (ESCs) are offered for eligible installations on top of the Federal STC grants - making the conversion to a Rinnai Enviroflo Heat Pump the obvious low-cost choice.

The value of STCs and State Grants are a tradable, market driven commodity. Values are subject to daily variation and are valid as of 12.12.2025.

*7 year extended Inner Storage Cylinder warranty available subject to participating in the Rinnai scheduled service program. For full terms and conditions please refer to the related warranty booklet.
**Energy saving based on a Rinnai Enviroflo AR Series Heat Pump when compared to a standard electric water heater of the same capacity during peak winter load in Zone 3 and 4 based on AS/NZS4234. Savings will vary depending on location (Zone 1-5), type of water heater being replaced, hot water consumption and associated fuel tariffs.
***R290: is a refrigerant used in air conditioning units that delivers high energy efficiency while reducing environmental impact. Its superior performance makes it a cost-effective alternative to traditional refrigerants.
#A noise level of 45 dB(A) is considered very quiet - comparable to the sound of a modern dishwasher or air conditioner, and noticeably quieter than a normal conversation.
