Pump power rises roughly with the cube of speed, so running at half speed for twice as long uses about a quarter of the energy.
Most pools are turned over more often than they need. Cutting an hour a day is free money all season.
A variable-speed pump is one of the few upgrades that routinely pays back within two seasons.
