Hot Water Rebates, Tariffs & Savings
All of this local interest is being helped along by generous incentives. Homeowners in Central Park can often access Australian Government Small‑scale Technology Certificates (STCs) on eligible solar hot water systems and heat pump hot water systems, plus Victorian state‑based programs that effectively act as a solar hot water rebate or heat pump hot water rebate. For some properties, there may also be an electric hot water system rebate when replacing old, inefficient units. These incentives can slice a substantial percentage off the upfront hot water system price or solar hot water price and bring the heat pump hot water price into reach for more families.
Once installed, many Central Park households see typical savings of several hundred dollars a year, especially when pairing a new hot water installation with rooftop solar and smart controls. Using timers or solar‑diversion to heat water in the middle of the day can shorten payback periods significantly.

Whether you are comparing electric hot water vs gas hot water, weighing up heat pump vs solar hot water, or just wondering about hot water system cost in general, it pays to get tailored advice. If your current unit is older, noisy or struggling, it may be time to look at heat pump hot water installation, solar hot water repair or even a full solar hot water tank replacement.
