VFDs in pool pump applications are able to cut electricity and maintenance costs monumentally. The VFD allows the pump, even if oversized, to be run at slower speeds using less electricity, and the VFD can easily change the pump speed depending on the pool’s conditions.
In this way, do variable speed pumps last longer?
They are also much quieter, vibrate less, run cooler, last longer, are digitally controlled, and have advanced diagnostics. Basically, variable speed pumps are the Cadillac of pool pumps, and most studies show that they are 90% more efficient than standard one-speed pumps.
Moreover, should pool pump run continuously?
Although it’s generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time. A proactive, productive and energy-saving maintenance activity is to remove the debris floating on the pool surface with a hand-held skimmer.
How long do Pentair pool pumps last?
Your pool pump should be replaced anywhere between 8 to 15 years depending on the quality, and a full replacement may cost over $800.
However, it is important to note that a variable speed pool pump should ideally be running 24 hours a day to ensure proper and optimal water circulation. When your pool pump is not running, the water is sitting stagnant in your pool allowing bacteria to survive and grow.
When it comes down to it, both pumps have their own strengths and weaknesses. The Hayward EcoStar has better energy efficiency and the Pentair IntelliFlo has a reputation for longevity with a proven track record. It’s a close battle between the two pumps and it really comes down to personal preference.
With a variable speed pump a pool owner can circulate their water at lower flow rates for a more prolonged period of the day without added energy consumption. This study by the National Renewable Energy Laboratory confirms that variable speed pumps are significantly more energy efficient than single speed pumps.
A Worthwhile Investment
Even at a higher initial cost than single-speed pumps, the best variable speed pumps are the superior investment because they offer prolonged filtration, more water turnover, and lengthier sanitation durations. These benefits make it easier to maintain your pool.
Suction cleaners typically run at around 2200-2400 RPM. Heaters require 20 to 40 Gallons Per Minute (GPM) so might run at around half speed or a little higher. You would probably want to run your Spa at up to full speed, 3450, for maximum effect.
