In 3429, most homes are detached houses with three or four bedrooms, so hot water demand is steady and predictable.

Hot Water Rebates, Tariffs & Savings
For homeowners in Wildwood, hot water VIC incentives make upgrading much more affordable. Federal Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that comes off the upfront hot water system price. Victoria also offers state-based support for efficient hot water, and there may be an electric hot water system rebate when you replace old, inefficient models. Together, these hot water rebate VIC programs can reduce the heat pump hot water price or solar hot water price by a substantial percentage, cutting payback times to just a few years in many cases. By adding timers or solar diversion, you can push even more of your hot water energy use into the middle of the day when your panels are producing, improving savings further.
If you are weighing up heat pump vs solar hot water, or even solar hot water vs electric hot water, it helps to look beyond simple hot water system cost and consider long term bills, reliability and your plans for going off gas. Many Wildwood households are already moving from electric hot water vs gas hot water towards an energy efficient hot water system such as a Sanden heat pump, Rheem heat pump hot water or Chromagen solar hot water paired with rooftop PV. Quality brands also tend to need less solar hot water repair and general hot water repair over their life.
If your current unit is more than 10 years old, running out of hot water, or needing regular repairs, it is a good time to check if your Wildwood home is ready for a hot water upgrade.
