With a median household income of about $964 a week and many residents on fixed incomes, reducing running costs without sacrificing comfort simply makes sense.
In a community with more than 3,500 occupied private dwellings and plenty of three‑bedroom homes, hot water demand is steady, but the way you supply it can be much smarter.

• Old electric to heat pump hot water installation: $350–$700 per year • Gas to heat pump hot water system: $250–$600 per year • Gas to solar hot water installation: $250–$550 per year • Old electric to modern electric hot water installation with solar PV: $200–$450 per year
These savings will vary with household size and tariffs, but they show why locals are weighing up heat pump vs solar hot water, and even solar hot water vs electric hot water backed by rooftop solar.
Efficient systems are already well established here. In Kalimna and the wider 3909 area, there have been around 840 efficient hot water installations – mainly heat pump and solar hot water systems. Installations really took off around 2009, with strong years through 2011–2015 as rebates and rising power prices pushed people towards an all‑electric home.
