Hot Water Rebates, Tariffs & Savings

For Yarrawarrah homeowners, the economics of hot water installation are helped along by a mix of federal and NSW incentives. Under the Small‑scale Renewable Energy Scheme, eligible heat pump and solar hot water systems earn Small‑scale Technology Certificates (STCs), which effectively discount the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate nsw programs can offer additional support for swapping out old electric or gas units for efficient electric hot water system rebate eligible models, or for heat pump hot water systems under state schemes.

When you combine these rebates, the effective hot water system price / cost can drop by a substantial percentage, often trimming thousands off larger systems. That means the payback period for a quality sanden heat pump or rheem heat pump hot water system can be cut to just a few years, particularly if you already have solar and use timers or smart controls to run your unit in the middle of the day. Many Yarrawarrah families are seeing hundreds of dollars per year in savings, especially when comparing heat pump vs solar hot water and choosing the option that best matches their roof, budget and hot water demand.
