Adelaide Hot Water Pricing Guide (Typical Ranges)

1) Hot Water Repairs (Most Common Jobs)

Most hot water repairs fall into a predictable range depending on the fault and parts needed. As a general guide, hot water repairs are often quoted in the hundreds (not thousands) unless a major component has failed.

Common repairs include:

  • Thermostat or element replacement

  • Valves, tempering valve, pressure relief valve

  • Leaks on fittings/pipework

  • Pilot/ignition faults (gas)

  • Error codes & electrical faults (heat pumps/instant systems)

Best practice: We diagnose first, then quote the repair before work starts.

2) Hot Water System Installation / Replacement Costs (Installed)

These are typical installed price ranges across Australia (Adelaide is usually in-line, but access and compliance can change totals).

Electric storage (installed): commonly the cheapest to install (best for budget replacements).
Gas systems (installed): typically mid-range.
Solar hot water (installed): typically $3,000–$7,000, and you may also need to allow $1,000+ for a booster on some setups.
Heat pump systems: unit prices typically range from $2,500–$5,500, with installed costs varying based on site access, electrical and plumbing requirements.

Heat Pump vs Solar: Which One Is Better in Adelaide?

If you’ve been comparing “solar vs heat pump”: here’s the straight answer.

  • Heat pumps are usually the best choice when you don’t want roof panels, have limited roof space, or want a high-efficiency upgrade with strong rebates.

  • Solar hot water can be brilliant when you’ve got clear roof space, good orientation, and you want the lowest possible running costs (with a booster for winter/overcast days).

If you tell us your household size + current system type, we’ll recommend the best option for your goals (saving money vs lowest upfront vs fastest changeover).
