Variable-speed vs single-speed pool pumps: Variable-speed is the only real choice for 2025

Single-speed pumps are obsolete — they waste power and many jurisdictions are phasing them out. Variable-speed pumps cut energy use by 50-80% by running low for daily filtration and high only for cleaning or heating. The top brands (Pentair, Hayward, Jandy) are all excellent, so pick based on your existing automation system. The higher install cost pays back in a year or two.
