Variable speed filter pumps have taken the market by storm, promising energy savings of up to $100 or more in some cases per month. Is this a clever marketing ploy or a legitimate claim based on research, supported by industry professionals?
The simple answer is this: The savings are real. The technology works. Think about this, what major household appliance or device can claim the ability to pay for itself in less than two years? The short answer is a variable speed filter pump. Because its primary purpose is simply to move water through a filtration system and circulate water within the pool, pool owners can drastically slow down their filter pumps and simply run them longer (ensuring the same amount of total water turnover, just over a longer duration). This means that pool owners can keep their pools clean and free of debris for a FRACTION of the cost.
One might ask: ‘That’s great, but why don’t I just buy a smaller pool pump?’ The answer lies in the ability of a variable speed pump to provide flexibility. Pool owners can manipulate the speed of their pumps to vacuum their pools, run automatic pool sweeps, run water efficiently through solar thermal panels, operate chlorine generators and a host of other possible scenarios.
Variable speed pumps are at least 30% more energy efficient if run at the equivalent flow rate as the current single speed pump no matter what horsepower it is.
Why is my pump running in the middle of the night when it’s not supposed to? Why is my energy bill so high in the winter when I’m not running my pump many hours a day? Did you know about control system freeze protection? This is a built-in function of most manufacturers control systems that turn the filter pump on when the air temperature approaches freezing. This is a perfect use for a variable speed pump. While the filter pump runs in freeze protection mode for multiple hours you will be saving at least 30% but if configured properly much more than that.

|The average initial cost of an installed variable speed pump:||$2,350.00|
|1st year Savings:||-$1,100.00|
|2nd year Savings:||-$1,100.00|
|3rd year Savings:||-$1,100.00|
|4th year Savings:||-$1,100.00|
|5th year Savings:||-$1,100.00|
|Cost of ownership after 5 years:||-$3,150.00|
