Kealba’s climate is well suited to efficient hot water. Nearby Keilor records mean daily solar exposure of around 15 MJ/m², which works out to roughly 4.2 kWh of solar energy per square metre per day. That strong sunlight helps a solar hot water heating system and heat pump hot water perform well year-round, especially when paired with rooftop solar. In a suburb with a high share of separate houses and plenty of families, shifting from older gas or resistive electric hot water to an energy efficient hot water system is a logical next step in electrifying the home and reducing running costs.
In 3021, many three‑bedroom homes have moderate to high hot water demand, from evening showers to weekend laundry loads. That is driving interest in options like a rheem solar hot water system, rinnai solar hot water, a sanden heat pump or other brands such as Thermann and Solahart for both new builds and replacements. Homeowners are comparing electric hot water vs gas hot water, and often find a quality heat pump hot water installation or solar hot water installation gives the most efficient hot water system over the long term. For some, a modern electric hot water system tied to rooftop solar and a smart timer is the best balance of upfront hot water system price and ongoing savings.
Typical bill savings in Kealba for an average household can look like this:
• Old electric to quality heat pump hot water system: save around $350–$700 per year • Gas storage to heat pump hot water: save roughly $250–$500 per year • Gas storage to solar hot water system: save about $200–$450 per year • Old electric to modern electric hot water system with solar: save around $200–$400 per year
