How to lower the cost of running a pool pump

Pool pumps can be one of the biggest electricity users in a home with a pool because they run for many hours every day of the season. A single-speed 1–2 HP pump typically draws 1,000–2,500W. Variable-speed pumps are dramatically more efficient: running at low speed for longer moves the same water with a fraction of the energy, which is why many states now require them for new installs.

  • Switch to a variable-speed pump — savings of 50–80% are common.
  • Run the pump only as long as needed to turn over the water once a day.
  • Keep skimmer baskets and filters clean so the pump doesn't strain.
  • Summers in Montana are relatively mild, so cooling costs are concentrated in a few hot weeks each year.
