Upgrading from older gas or off‑peak electric to an efficient hot water upgrade is a simple way to lock in long term savings.
The local climate helps. The nearby Tarralangi weather station records an average annual solar exposure of about 14.8 MJ/m² per day – roughly 4.1 kWh/m²/day – which is strong enough to support both a solar hot water heating system and a high performance heat pump hot water system. In a postcode with more than 12,000 occupied dwellings and a high share of separate houses, there is plenty of suitable roof and yard space for solar hot water installation or an outdoor heat pump hot water installation that can run quietly in the background.
Across 3844 there have already been 2,236 efficient hot water systems installed, combining heat pumps and solar hot water. Installations climbed sharply from just a handful in the early 2000s to peaks of over 200 systems per year around 2010 and again in 2021, before settling into steady growth.

For a typical Carrajung South family, hot water can be one of the biggest single energy users in the home. Swapping an old electric hot water system for a quality heat pump hot water system, such as a Sanden heat pump or Rheem heat pump hot water unit, can cut hot water energy use by up to two‑thirds. Many locals also pair a rheem solar hot water or rinnai solar hot water setup with existing rooftop solar, or choose brands like Chromagen solar hot water to maximise self‑consumption. These systems are often shortlisted when people search for the best hot water system Australia wide or the best heat pump hot water system for regional climates.
Average annual bill savings for Carrajung South homes are compelling:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water system: save about $200–$550 per year. • Old electric to modern electric hot water installation with solar: save roughly $200–$500 per year.
Local households are also weighing up heat pump vs solar hot water, and solar hot water vs electric hot water, depending on roof space, budget and whether they plan to go all‑electric. When a solar hot water tank replacement is due, many owners take the chance to compare heat pump hot water price / cost with solar hot water price / cost and a modern electric hot water installation. Factoring in rebates, the hot water system price / cost difference up‑front often shrinks dramatically.
