Energy calculators for WA homes | WattMate

Pool pump efficiency calculator

See what a variable-speed pool pump saves on running costs for a typical Australian pool.

Pool pumps are often the biggest energy user in Australian homes with pools, consuming 2,000-3,000 kWh/year. Variable-speed pumps can reduce this by 65-75%, saving $600-900 annually.

Average: 40,000-60,000L

Typical: 1000-2000W

Recommended: 6 hours

Quality brands: $900-$1,800

Pool pump optimisation tips

  • •Variable-speed pumps use inverter technology - run longer at lower speeds for better filtration & efficiency
  • •Run during off-peak hours if on time-of-use tariff (typically 10pm-7am in WA)
  • •Pair with solar - run pump during the day to use free solar power
  • •Clean filters regularly - dirty filters make pumps work harder
  • •Reduce runtime in winter - pools need less circulation in cooler months
  • This upgrade pays for itself in under 2.5 years.
Estimates only — not financial advice

This calculator provides estimates only and does not constitute financial, tax, or legal advice. Actual savings, payback periods, and rebate amounts depend on your specific usage, solar generation, electricity plan, and the WA Battery Scheme/STC rules current at the time of purchase — figures shown here may not reflect current rates.

Consult a licensed installer, financial adviser, or your electricity retailer before making a purchase decision. WattMate is not responsible for financial decisions made based on these estimates.

Assumptions

  • Variable-speed pump modelled at 35% of current pump power on average
  • Seasonal factors: year-round 100%, mainly summer 75%, summer only 50%
  • Recommended runtime: 6 hours per 50,000 L of pool volume
  • Synergy A1 (WA) usage rate default: 0.3326 $/kWh
