Rocky Plain is quietly well‑positioned for efficient hot water. The local weather station at Eucumbene Trout Farm records an average annual solar exposure of about 16.7 MJ/m² per day – roughly 4.6 kWh/m²/day – which is solid for both a solar hot water heating system and a high‑performance heat pump. That sunshine, combined with cool winters, means a quality heat pump hot water system or solar hot water system can deliver strong annual hot water energy savings for homeowners in Rocky Plain, especially those already running rooftop solar.
With 1,095 dwellings in the 2628 postcode and many owned outright or with a mortgage, there is strong potential for upgrades as older cylinders fail. A typical family of three or four in Rocky Plain will often find hot water is one of their biggest energy uses, so choosing the most efficient hot water system becomes a smart financial decision as well as a comfort upgrade. Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water are all common choices when people here compare the best hot water system Australia options and weigh up heat pump vs solar hot water or solar hot water vs electric hot water.
Average annual bill savings will vary with tariffs, usage and whether you have solar, but as a guide you might expect:
• Upgrading old electric to a quality heat pump hot water system: around $400–$800 a year off bills. • Switching gas to heat pump: roughly $300–$700 a year in savings, depending on gas prices. • Switching gas to a solar hot water heating system with electric boost: around $300–$600 a year. • Upgrading an old electric unit to a modern electric hot water system timed to run on solar: about $200–$500 a year.
In Rocky Plain, there have already been 49 efficient hot water installations recorded, including both heat pump hot water installation and solar hot water installation. Installations really picked up around 2008–2011, with 7 systems in 2008, 10 in 2009 and 8 in 2010, then steady interest through the 2010s and new systems still going in as recently as 2024.

Hot Water Rebates, Tariffs & Savings
Right across Rocky Plain there is growing interest in replacing ageing gas or resistive electric units with efficient options such as a heat pump hot water system, new electric hot water installation or a solar hot water installation. Australian Federal Government incentives, like Small‑scale Technology Certificates (STCs), help cut the solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate, which together can reduce the upfront hot water system price / cost by a substantial percentage.
For a typical Rocky Plain household, shifting to an energy efficient hot water system can trim hundreds of dollars a year from bills, particularly when paired with rooftop solar and smart timers or solar‑diversion controls. When you add rebates to the equation, payback periods for a quality heat pump or solar hot water system can be cut to just a few years, especially if you are moving away from electric hot water vs gas hot water tariffs and towards daytime solar use. That is why many locals now see a modern electric hot water system or heat pump as the best heat pump hot water system pathway to an all‑electric home.
