Cooloola’s sunny climate is perfect for efficient hot water. The Tin Can Bay weather station records about 19 MJ/m² of solar exposure a day on average, which is roughly 5.3 kWh/m² – ideal for a solar hot water system or a heat pump hot water system that runs hardest when the sun is out.

Across the 4580 area there are around 2,377 occupied private dwellings, many owned outright, so it makes sense that more people are looking at long‑term savings rather than band‑aid hot water repair jobs on ageing tanks. A modern solar hot water heating system or the best heat pump hot water system you can reasonably afford will usually be the most efficient hot water system for our climate, especially when paired with rooftop solar.
For a typical Cooloola home, hot water can be one of the biggest energy users. Switching from gas or an old electric hot water system to an energy efficient hot water system such as a Sanden heat pump, Rheem heat pump hot water, Rheem solar hot water or Rinnai solar hot water can significantly reduce running costs. Brands like Chromagen solar hot water and other quality options are also common in Queensland, and a good installer can help you compare heat pump vs solar hot water for your roof, budget and usage. If you prefer to stay simple, a modern electric hot water system with solar‑timed controls can still be a smart upgrade, especially when you factor in an electric hot water system rebate.
Average annual bill savings for Cooloola homes can look like this:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas to heat pump hot water system: about $250–$600 per year • Gas to solar hot water system: about $200–$550 per year • Old electric to modern electric hot water installation with good solar: about $150–$400 per year
Recent installs in Cooloola show how quickly things are changing. There have already been around 750 efficient hot water installations (heat pump and solar hot water) recorded in the 4580 postcode. Install activity was modest in the early 2000s, then picked up around 2007–2010, dipped, and surged again with 71 installs in 2019 and a peak of 103 systems in 2023. That steady growth reflects a clear shift towards electrification, lower running costs and cleaner hot water QLD‑wide, with Cooloola residents keen to get off gas and tame their power bills.
Even if you are just starting to look into options, it is worth understanding the hot water rebate QLD homeowners can access. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, Queensland programs often provide a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for approved upgrades, helping to bring the overall hot water system price / cost down by a substantial percentage. When you combine rebates with solar, timers or solar‑diversion controls, payback periods can shrink to just a few years, especially if you are moving from solar hot water vs electric hot water on old tariffs or comparing electric hot water vs gas hot water.
If your tank is ageing, you are facing another solar hot water repair, or you suspect a solar hot water tank replacement is coming up, it is a good time to compare options like solar hot water vs electric hot water and decide what will be the best hot water system Australia can offer for your situation.
