Across 2500, efficient hot water systems are steadily appearing alongside rooftop solar, with 666 heat pump and solar hot water installations already recorded. Average household size and the high proportion of smaller dwellings mean a correctly sized heat pump hot water installation or solar hot water installation can comfortably cover daily demand without wasting energy. For many homes, hot water can be one of the biggest single energy loads, so choosing the most efficient hot water system has a big impact on overall bills.

Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in Keiraville in replacing old gas or electric hot water with efficient options such as heat pump hot water, modern electric hot water system upgrades and solar hot water installation. Homeowners can often access Australian Government Small‑scale Technology Certificates (STCs), which effectively act as an upfront discount on eligible solar hot water and heat pump hot water systems. On top of that, state‑based schemes can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some programs, all helping to reduce the heat pump hot water price or cost and the solar hot water price or cost.
For many Keiraville homes, these hot water rebate NSW incentives can cut the system cost by a substantial percentage and shorten payback times to just a few years, especially when combined with rooftop solar. Typical savings from an efficient hot water upgrade can be in the hundreds of dollars per year, and using timers or solar diversion to run an electric hot water system when your solar is producing can improve those savings even further. When you weigh up electric hot water vs gas hot water, or heat pump vs solar hot water, it’s worth factoring in both rebates and your likely usage pattern.
