Hot Water Rebates, Tariffs & Savings
Across Darlinghurst, more owners are now replacing old gas or resistive electric hot water with efficient options like heat pumps, newer electric hot water systems and solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the supply and install cost. NSW programs can also support efficient electric hot water installation and heat pump upgrades, and in some cases operate like an electric hot water system rebate when you move away from gas.
When you factor in these hot water rebate NSW schemes, the effective hot water system price or cost can drop by a substantial percentage, shortening payback times. A quality heat pump hot water price or cost, once rebates are applied, can rival a basic gas replacement while delivering much lower bills. Likewise, a solar hot water price or cost can be trimmed significantly with STCs, especially for systems like Rheem solar hot water or Chromagen solar hot water. Typical savings from an efficient hot water upgrade are often in the hundreds of dollars per year, and payback periods can be cut further by using timers, smart controls or solar diversion to run your system when rooftop solar is producing. For many households, heat pump vs solar hot water decisions come down to roof space, strata approvals and whether you already have solar PV, but both options are usually far more efficient than electric hot water vs gas hot water in their traditional forms.
If your current unit is leaking, more than 10 years old, or you are thinking about going all‑electric, now is a good time to look at options like a heat pump hot water system, solar hot water vs electric hot water, or even a simple solar hot water tank replacement tied into existing panels.
