With an average household size of around 2.6 people and more than 7,600 occupied dwellings across the 2330 postcode, reliable hot water is non‑negotiable.

Mount Thorley enjoys strong sunshine, with average annual solar exposure of about 17.1 MJ/m² a day (roughly 4.75 kWh/m²/day). That is ideal for a solar hot water heating system or a high quality heat pump hot water installation that uses the ambient air to do most of the work. With many homes owned with a mortgage and a solid median household income, investing in the most efficient hot water system is a smart way to cut running costs for years, especially when you consider the annual hot water energy savings possible by moving away from old resistive electric or gas storage.
Across the 2330 area, separate houses dominate, many with three or four bedrooms, which means higher hot water demand and more to gain from an energy efficient hot water system. Hot water can be one of the largest single energy users in a home, so choosing between heat pump vs solar hot water or even a modern electric hot water installation tied to rooftop solar can make a big dent in quarterly bills. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are all common choices for locals wanting the best hot water system Australia can offer for long‑term reliability.
Typical annual bill savings in Mount Thorley look like this:
• Old electric to heat pump hot water system: about $400–$800 per year • Gas storage to heat pump hot water: about $300–$600 per year • Gas to solar hot water system: about $250–$550 per year • Old electric to modern electric hot water system with good solar: about $200–$500 per year
Over time, these savings easily outweigh the hot water system price, especially once you factor in rebates and smart tariffs.
Efficient hot water has taken off locally. In the 2330 postcode there have already been 1,261 efficient hot water installations, including heat pump and solar hot water installation projects.

Solar hot water repair and hot water repair work on older systems often prompts people to compare a simple fix with the long‑term benefits of a full hot water upgrade.
Hot Water Rebates, Tariffs & Savings
Right across Mount Thorley, more owners are asking whether solar hot water vs electric hot water or electric hot water vs gas hot water will leave them better off. For many, the answer is to move to a high efficiency heat pump or solar hot water system backed by a hot water rebate NSW households can access. Federal incentives such as Small‑scale Technology Certificates (STCs) reduce the effective solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of this, state‑based schemes can offer a heat pump hot water rebate or solar hot water rebate, and there are also programs that support an electric hot water system rebate when you are replacing inefficient units. These discounts can shave a substantial percentage off the upfront hot water system price / cost.
When you combine rebates with smart tariffs, timers or solar‑diversion that runs your electric hot water system when rooftop solar is exporting, payback periods can drop to just a few years. Many Mount Thorley households see hundreds of dollars a year off their energy bills, especially when they pair a new system with a solar hot water tank replacement or a full heat pump hot water installation sized correctly for their family.
