Our sunshine is a big part of the story. Idalia’s mean daily solar exposure sits around 20.9 MJ/m², or roughly 5.8 kWh/m² per day over the year. That strong Townsville sun is ideal for a solar hot water system or a high‑efficiency heat pump hot water system that draws energy from the warm air.

Around Idalia you’ll see a mix of systems: traditional electric hot water system units, gas storage, and an increasing number of energy efficient hot water system upgrades. Brands like Rheem and Rinnai are common for both solar hot water heating system setups and electric hot water installation, while Sanden and Stiebel Eltron style systems are popular choices when people start researching the best heat pump hot water system for our climate. Many households look up “heat pump vs solar hot water” or “solar hot water vs electric hot water” as they weigh up what will be the most efficient hot water system for their family’s usage and budget.
In 4811, efficient hot water systems have already made a mark, with 303 heat pump and solar hot water installations recorded. Installations climbed sharply around 2008–2010, with a peak of 45 systems in 2009, and there has been a steady trickle of new installs each year since. That pattern shows a clear, ongoing interest in electrification, lower running costs and reducing reliance on gas hot water. As more Idalia homes add rooftop solar, pairing it with a heat pump hot water installation or solar hot water installation is becoming the logical next step.
When people start comparing hot water system price or cost, they often look at running costs as closely as the sticker price. A typical upgrade can deliver real savings:
• Old electric to heat pump: around $350–$700 a year off bills. • Gas to heat pump: around $300–$600 a year. • Gas to solar hot water system: roughly $250–$550 a year. • Old electric to modern electric hot water system run on solar: around $250–$500 a year.
Those savings make heat pump hot water price or cost, and solar hot water price or cost, look much more attractive over the life of the system. Many Idalia households also ask about solar hot water tank replacement, hot water repair options, and which units are considered the best hot water system Australia‑wide for reliability and warranty support. Well‑known names like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water and Rheem heat pump hot water are common choices, alongside premium heat pumps such as Sanden heat pump systems for those chasing maximum efficiency.
