Hot water systems in Willung South
Across Willung South and the wider 3844 area, more households are swapping old gas and power‑hungry units for an energy efficient hot water system. With an average household size of around 2.4 people and more than 8,800 homes owned outright or with a mortgage, plenty of local families are looking to lock in lower running costs rather than keep feeding rising energy bills.

In Willung South and surrounds, most properties are standalone homes with three or four bedrooms, so hot water demand is steady, especially for families and tradies. Hot water can easily chew through a quarter of a home’s energy use, so it is no surprise we are seeing growing interest in options like heat pump vs solar hot water and even solar hot water vs electric hot water for all‑electric homes. Brands such as Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are common choices for those chasing the most efficient hot water system, while Rheem solar hot water and Chromagen solar hot water are popular on rural and semi‑rural properties.
For a typical 3844 household, the right hot water installation can trim bills nicely. As a guide, realistic annual bill savings might look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas storage to heat pump hot water: $300–$600 per year • Gas storage to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation backed by rooftop solar: $250–$500 per year
