On farms and lifestyle blocks, hot water energy use can be a surprisingly large share of total household energy, especially where older electric hot water vs gas hot water setups are still common. Upgrading to an energy efficient hot water system is a logical next step after solar panels, with many Coominglah households able to save hundreds of dollars a year in hot water energy savings.
Around 4630 there are 943 occupied private dwellings and a high share of homes owned outright, often by older residents (the median age is 51, with many over 65). That means plenty of people planning to stay put and thinking about long‑term comfort and reliability.

When it comes to brands, Coominglah homeowners often look for proven names. Rheem solar hot water and Rheem heat pump hot water units are popular for their reliability, while Rinnai solar hot water and Chromagen solar hot water systems offer strong performance where roof space and solar exposure are good. For those chasing ultra‑low running costs, a Sanden heat pump is frequently in the mix when comparing the best heat pump hot water system options. Many locals weigh up heat pump vs solar hot water against their roof layout, water use and whether they already have solar PV.
Efficient hot water systems are already appearing across the postcode. There have been 66 efficient hot water installations (heat pump and solar hot water installations combined) recorded in 4630. Install numbers ramped up around 2009–2010, when 13 and 7 systems went in, and have continued at a steady pace with new installs in 2016, 2019, 2022 and 2023. This pattern shows growing interest in electrification, lower running costs and cleaner hot water QLD wide, even in smaller communities like Coominglah.
Typical hot water system price or cost depends on technology and size.

A solar hot water installation or heat pump hot water installation costs more initially, but can quickly pay for itself through savings on power.
Average annual bill savings for Coominglah households can look like:
• Replacing an old electric unit with a quality heat pump: $350–$700 per year • Switching gas to a heat pump hot water system: $250–$600 per year • Switching gas to a solar hot water system: $200–$550 per year • Upgrading an old electric to a modern electric hot water system run on solar: $200–$500 per year
When comparing solar hot water vs electric hot water, or electric hot water vs gas hot water, it is worth factoring in rebates. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump hot water installations, effectively lowering the heat pump hot water price or cost and solar hot water price or cost at the point of sale. On top of that, Queensland hot water rebate QLD programs and electric hot water system rebate offers for efficient models can further reduce the upfront outlay. In many cases, combined discounts can knock a substantial percentage off the system cost and cut the payback period to just a few years, especially if you use timers or solar‑diversion to run the system when your PV is generating.
If your tank is rusting, you are facing solar hot water repair bills, or you suspect you will soon need a solar hot water tank replacement, it is a good time to reassess the best hot water system Australia has to offer for your situation. Whether that is a new electric hot water system, a rheem solar hot water package, a rinnai solar hot water upgrade or a high‑performance sanden heat pump, the key is matching system size, running costs and rebates to the way your household actually uses hot water.
