Multi Speed pumps
According to utilities offering rebates, the most energy-efficient pool pump — the only ones that qualify for efficiency rebates — are multispeed pumps with automatic control systems. Multispeed or energy efficient pool pumps can also significantly reduce the power consumption of a swimming pool by over 65%. The difference over a season can be immense. Pumps come in two-speed, four-speed, and variable-speed models, so you can turn the speed down for regular daily use saving a lot of energy, and use higher settings for more thorough, less frequent cleanings. New energy-efficient pumps also move the water more efficiently for further savings. Since pumps circulate the water to keep it clean, the better they work, the less a filter has to work.
Here are realistic estimates when comparing IntelliFlo pumps to a traditional pump running 12 hours per day at various utility rates (in dollars per kilowatt hour [kWh]) in a 20,000 gallon pool.
At $0.16/kWh estimated savings of up to $1,500* per year.
At $0.20/kWh estimated savings of up to $1,800* per year.
At $0.30/kWh estimated savings of up to $2,700* per year.
