Pump Recommendations
Energy Cost Comparison
Single-Speed Pump
- ✓ Lower initial cost
- ✗ Higher energy bills
- ✗ One speed only
Variable-Speed Pump
- ✓ Save $180/year
- ✓ Quieter operation
- ✓ Longer lifespan
💡 Savings: A variable-speed pump typically pays for itself in 2-3 years through energy savings. Annual savings: $180
Understanding Pump Sizing
Turnover Time: The time it takes for your pump to circulate the entire pool volume through the filter. Most pools should complete 1-2 turnovers per day (8-12 hour turnover time).
Variable-Speed vs Single-Speed: Variable-speed pumps can adjust their speed based on pool needs, running slower for daily circulation and faster for cleaning or water features. This flexibility typically reduces energy consumption by 70% or more.
Oversizing Warning: Bigger isn't always better! An oversized pump wastes energy and can create excessive pressure that strains your filtration system.
