Hot water systems in Gawler
Across Gawler and the wider 7315 area, more households are moving away from old gas and hungry electric units towards an energy efficient hot water system. With an average household size of around 2.3 people and a big share of homes owned outright or with a mortgage, many locals are looking at long‑term savings and comfort rather than just the cheapest upfront hot water system price. Swapping an older gas or electric hot water system for a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Gawler’s climate helps. The nearby North Motton weather station records mean daily solar exposure of about 14.5 MJ/m², or roughly 4 kWh/m² per day over the year, which is plenty to support a solar hot water heating system or a high‑performance heat pump. With many separate houses and a good number of families and retirees, demand for reliable, low‑running‑cost hot water is strong, and the annual hot water energy savings on offer are very real when you upgrade.
For a typical Gawler home, hot water is one of the biggest single energy users. That is why more locals are asking about heat pump vs solar hot water, and which option will be the most efficient hot water system for their situation. A quality heat pump hot water installation can suit shaded blocks or homes with smaller roofs, while a solar hot water installation works brilliantly on sunnier sites, especially when paired with rooftop solar. Modern electric hot water installation can also make sense where you already have solar and want a simple, reliable tank that soaks up excess daytime generation.
Here are some realistic average annual bill savings many Gawler households can see:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to modern electric hot water with solar: save around $250–$500 per year.
