A pump that can save money, time, and energy? Sign me up!


Let’s face it. It’s been another tough year. As you have been dealing with the effects on the “new normal”, you probably missed the pool news that happened this summer. On July 19, 2021, the Department of Energy (DOE) passed legislation on pool pumps. The new federal regulation says that self-priming filtration pumps past a certain horsepower (1.0 HP) threshold – whether residential or commercial – must meet an established performance standard. This can be met with variable-speed or multi-speed pumps.


What is a variable speed pump (VSP)? Simply stated, it is a pump that can be operated at varying speeds. The pump you currently have only operates at one speed. By being able to change the operation of your speed, you decrease and increase operation when needed. You are now in control of the speed. But what does this mean for you?


By being able to decrease speed, you also decrease energy consumption which increases savings. While the initial price of the pump is higher than a single speed pump, you will be saving every month over the life of the pump giving you a great return on investment. You would think, cut the RPM speed of the pump in half, double the energy savings. But in fact, it cubes (x3) the energy savings! So at half speed, it saves eight (8) times the energy savings at full speed. Also, pumps do not need to run at full speed to keep your water clean, so you will also be saving energy.

Variable speed pumps also run quieter which will help with noise pollution in your backyard oasis. No one wants to hear a constant, dull drone while they are enjoying their swimming pool. This will also be a benefit to your neighbors.


With the slower operating speeds available with VSP, this allows the filter to work more efficiently resulting in a cleaner pool. By working at a slower speed, the filter may be able to catch more and smaller particles. And you can run your pump longer at a slower speed which will up keep your water moving. Moving water helps to maintain a clear pool and prevent algae from clinging onto pool surfaces.


Ultimately, a VSP can keep your pool water circulating and filtering all day with increasing energy usage or your utility bill. Simply stated, you’ll get proper pool water circulation for less money. It’s a win-win!
