Hot water systems in Pernatty
In a remote spot like Pernatty, having a reliable, energy efficient hot water system is just as important as a good rainwater tank.

With only around 14 dwellings and an average household size of about two people, most homes here are owner‑managed and practical, with median household incomes strong enough to justify smart upgrades that pay for themselves over time.
Pernatty’s climate is ideal for efficient hot water. The area enjoys about 19.9 MJ/m² of mean daily solar exposure over the year – roughly 5.5 kWh/m² per day – which is excellent for both a solar hot water system and a heat pump hot water system drawing warmth from the air. For small households, hot water energy use can still be one of the biggest loads on the bill, so upgrading from old gas or a basic electric hot water system to an energy efficient hot water system can deliver meaningful annual hot water energy savings, especially in a sunny, off‑grid‑friendly place like Pernatty.
Across postcode 5713 there have already been 2 efficient hot water installations recorded, combining heat pump and solar hot water installation jobs. While that might sound small, it reflects a steady shift towards electrification and lower running costs in a tiny community. With most dwellings being two‑bedroom separate houses, demand is modest but consistent: enough hot water for showers, washing and a bit of laundry, without wasting power heating a huge tank.
For many residents, the key question is heat pump vs solar hot water. A roof‑mounted or ground‑mounted solar hot water heating system using brands like Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water can harness Pernatty’s strong sun, often paired with a solar PV system. A quality heat pump hot water installation, for example with a Sanden heat pump, Rheem heat pump hot water or other best heat pump hot water system options, can be ideal where roof space is limited or you want reliable performance day and night. Some households still choose a modern electric hot water installation, especially when combined with rooftop solar and timers, because solar hot water vs electric hot water with PV can both work well when designed properly.
Typical annual bill savings in regional SA for a well‑designed hot water upgrade look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water: save roughly $250–$600 per year. • Gas to solar hot water system: save about $200–$500 per year. • Old electric to modern electric hot water system run on solar: save around $250–$500 per year.
Actual hot water system price / cost will vary with tank size, brand and whether you need a solar hot water tank replacement, but many locals are surprised how affordable the most efficient hot water system can be once rebates are applied.
