How it works

Daily energy (kWh) = watts ÷ 1000 × hours/day. Yearly energy = daily × days run per year. Yearly cost = energy × rate; monthly is the yearly figure ÷ 12. Switching to a variable-speed pump and reducing run time are the two biggest savings.

Frequently asked questions

How long should a pool pump run?

Most pools only need 6–8 hours of turnover per day, often less with a variable-speed pump. Many people run pumps longer than necessary, wasting money.

Are variable-speed pumps worth it?

Usually yes — running slower for longer uses far less energy than a single-speed pump and often pays back within a couple of years.

Does off-peak running help?

If you have time-of-use pricing, scheduling the pump for off-peak hours can cut costs significantly without changing run time.
