Abernethy is well suited to efficient hot water upgrades. The Cessnock weather station records mean daily solar exposure of about 16.6 MJ/m², which works out to roughly 4.6 kWh/m² per day of sunshine across the year. That strong solar resource helps both a solar hot water heating system and a quality heat pump hot water system perform well. With many homes either owned outright or with a mortgage, and a median household income that supports sensible long‑term investments, upgrading from an older gas or resistive electric unit is a logical next step. Over the life of the system, annual hot water energy savings in Abernethy can add up to thousands of dollars.
In 2325, most homes are separate houses, and hot water demand is steady for typical three‑ and four‑bedroom households. Hot water can easily account for a quarter of total electricity use, so choosing the most efficient hot water system really matters. Locally, you will see brands like Rheem, Rinnai, Sanden and Thermann across roofs and backyards, from rheem solar hot water and rinnai solar hot water setups to premium sanden heat pump units and Thermann heat pump hot water systems. Many residents are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find what suits their roof space, budget and lifestyle.
Typical annual bill savings in Abernethy look like this:
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas to heat pump hot water: save around $300–$700 per year. • Gas to solar hot water system: save about $250–$600 per year. • Old electric to modern electric hot water installation with rooftop solar: save roughly $250–$500 per year.

Installations really ramped up around 2009–2011, with close to 150 systems a year going in at the peak, and while numbers have steadied in recent years, from 2020 through to 2024 there has been a consistent trickle of new heat pump hot water installation and solar hot water repair and replacement work. This steady trend shows growing interest in electrification, lower running costs and cleaner hot water NSW‑wide.
Hot Water Rebates, Tariffs & Savings
Homeowners in Abernethy are increasingly replacing old gas hot water with either a high‑efficiency heat pump or a solar hot water heating system, and some are opting for a well‑sized electric hot water system paired with rooftop solar. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively reducing the hot water system price at the point of sale. On top of that, state heat pump hot water rebate programs and electric hot water system rebate offers in NSW can further cut the heat pump hot water price or solar hot water price, sometimes slashing upfront costs by a substantial percentage.
For many Abernethy households, these hot water rebate NSW incentives mean a quality energy efficient hot water system can pay for itself in just a few years, especially when combined with solar.
