With a median household income around $2,000 a week and more than 4,200 homes owned outright or with a mortgage, cutting running costs without sacrificing comfort is a logical next step.
In the 2526 area, most dwellings are separate houses with three or four bedrooms, so hot water demand is steady, especially for families and multi‑shift households. Efficient hot water systems like Rheem heat pump hot water units, Sanden heat pump models and solar brands such as Solahart and Rinnai solar hot water are increasingly common choices for people wanting the most efficient hot water system they can get. These pair well with existing rooftop solar, and even a carefully chosen electric hot water installation can work brilliantly when timed to run on solar.
Typical annual bill savings in Unanderra Dc look like this:
• Old electric to quality heat pump hot water system: around $400–$800 per year • Gas storage to heat pump hot water system: roughly $300–$600 per year • Gas storage to solar hot water system: about $250–$550 per year • Old electric to modern electric hot water with good solar: around $200–$450 per year
