Around 457 dwellings in the 2716 postcode means plenty of hot water demand, and hot water can easily account for a quarter of a typical home’s electricity use. That is why more households are looking at the most efficient hot water system they can sensibly afford. Modern brands like Rheem heat pump hot water units, Sanden heat pump systems and roof‑mounted options such as Rheem solar hot water or Rinnai solar hot water are now common choices, with Chromagen solar hot water also appearing on local roofs. Many locals pair a solar hot water installation with existing rooftop solar to maximise self‑consumption, while others choose a quiet, all‑in‑one heat pump hot water installation to prepare for an all‑electric home.
In the 2716 area there have been 50 efficient hot water installations recorded – mainly heat pump and solar hot water installation jobs. Install numbers jumped around 2009–2012, when solar hot water rebate programs were strong, with 10 systems installed in 2009 and another 6 in both 2010 and 2012. More recently there has been a steady trickle of installs each year through to 2025, reflecting growing interest in electrification, lower bills and moving away from bottled or mains gas.

Choosing between heat pump vs solar hot water often comes down to roof space, household size and when you use hot water. A solar hot water vs electric hot water comparison usually shows solar well ahead on running costs, especially when you factor in a solar hot water rebate and lower solar hot water price / cost over the life of the system. Heat pump hot water price / cost has also fallen, and many locals now see a quality unit as the best heat pump hot water system choice for year‑round performance, even on frosty Riverina mornings.
For Mairjimmy households, federal Small‑scale Technology Certificates (STCs) can reduce the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs often support efficient heat pump hot water installation and, in some cases, electric hot water system rebate offers when replacing old, inefficient units. These hot water rebate nsw incentives can effectively trim the system cost by a substantial percentage and shorten payback periods to just a few years, especially if you use timers or solar‑diversion controls so your energy efficient hot water system runs when your solar is producing.
If your existing unit is leaking, unreliable or more than 10–12 years old, it may be time to compare electric hot water vs gas hot water and consider an upgrade.
