Why You Need a Variable Speed​Pool Pump?

Single-speed and two-speed pool pumps are officially a thing of the past. More and more pool owners are ditching the noisy, inefficient pumps that were once the norm and upgrading to variable speed pool pumps with far superior performance.

Since your pool pump is probably the largest consumer of electricity in your home, replacing your old single-speed pump with a more efficient variable-speed pool pump can greatly reduce your energy bills. However, without the right knowledge to properly set up a pool pump, some pool owners may miss out on some of the biggest benefits of an upgrade.

Pool pumps have improved significantly since they were first developed, and choosing the right pump can be one of the best investments you can make as a pool owner.

Here are the three top pool pump types on the market today:

The original style of the pool pump, and the cheapest, was a single-speed pump. These always run at full-rated horsepower at 3450 RPM and cannot be adjusted for speed. Since they only have one speed, they usually run at a higher speed than most pools need. They are the least efficient of the three pool pumps available.

Two-speed pool pumps have high and low-speed settings. They are more efficient than single-speed pumps and have a higher upfront cost. However, you won't get the maximum efficiency out of a two-speed pump because they can't be fine-tuned to a specific flow.

Variable speed pumps are by far the best option when it comes to pool pumps, they are much quieter than single or two-speed pumps and allow a full range of speeds to easily fine tune flow. They have the highest upfront cost of the three options, but they will save you money in the long run with lower operating costs.

Variable speed pool pumps are essential to running a healthy pool for a number of reasons. They are driven by motors other than single-speed and two-speed pumps, called permanent magnet motors. The same type of motor used in electric vehicles is much more efficient than the induction motors used in traditional single-speed and two-speed pool pumps.

These motors use permanent magnets to create a magnetic field between the rotor and the windings. The increase in efficiency is due to the magnets that spin the rotor, whereas standard induction motors require additional power to induce a magnetic field into the rotor.

Permanent magnet motors have an efficiency rating of 90%, while the average single-speed pool pump can only achieve an efficiency rating of 30% to 70%. This means that running a variable speed pool pump will consume significantly less energy for the same flow as a single speed pump.

Although variable speed pool pumps have a higher upfront cost, they will eventually pay for all those costs and save you more money over time. This is because a variable speed pool pump allows you to run your pool at a lower speed for a longer period of time as opposed to a single speed pump running at a higher speed for a shorter period of time.

Single-speed pool pumps often run much faster than necessary, which means they are constantly wasting energy. Slowing down your pool pump results in a disproportionate reduction in energy consumption - so even the slightest reduction in pump speed can save you a lot of money.

Since variable speed pool pumps have a more efficient motor and allow you to set the speed to the speed your pool needs and nothing more, they will save you the most on energy bills compared to any other pool pump.

Most pool owners who use single-speed pumps end up running them eight hours a day or less due to high energy costs and loud operating noise. This means that for most of the day, their pool water is stagnant and allows bacteria and other pollutants to thrive. As more pollutants build up, the pool will require more chlorine, which, in turn, will produce more toxic chloramines, which can cause irritation and chlorine odors.

In some cases, pool owners with single-speed pumps only run them at night to help keep their electricity bills down. This is worse because their pool water stagnates during the day when the sun is out, which leaves the sun's UV rays to degrade the pool's chlorine.

On the other hand, you can run a variable speed pool pump for longer, ideally 24 hours a day, with lower energy costs and without the annoyingly loud sound of a single speed pool pump. This will create better circulation in your pool, resulting in a healthier pool that requires fewer chemicals.

Any supplemental sanitation, such as AOP, UV, or ozone systems, will also perform better with a continuous cycle that can reduce chlorine levels to that of drinking water or less.

Single-speed pool pumps can be very loud, making them even more impractical to run overnight. Because variable speed pumps are quieter, they can be run 24/7 at lower speeds without keeping your family or neighbors up all night.

Running the pool pump at too high a speed will reduce the efficiency of the filter. By running the variable speed pump at a lower speed for longer, you can make your filter work more efficiently, leaving you with a cleaner pool and extending filter life.
