Save Money and Energy with a Variable Speed Pool Pump

In swimming pools, there are two types of pumps used – variable-speed pumps and single-speed pumps. Variable-speed pumps can operate between 50% to 500% faster than single-speed pumps.

A variable-speed pool pump is essentially a single-speed pump that can be set to vary the flow of water. This type of pump is good for a wide variety of applications but is mostly used in swimming pools. A variable speed pump will cycle back and forth between high and low flow rates. As a result, the pump operates at lower energy levels when the water level in the swimming pool is high. Because of this, the pump is less likely to burn out and has a longer lifespan.

Single-speed pool pump

It has a maximum flow rate setting. Most single-speed pumps do not have any variable settings. They have a set speed that is controlled by a mechanical or electronic mechanism. The flow rates they produce are fixed. Some single-speed pumps may have a higher or lower flow rate setting. The higher flow rate setting will produce a faster flow rate and the lower setting produces a slower flow rate.

What Makes Single-Speed Pool Pumps a Good Option:

  • They’re the best choice for your pool pump because they’re quieter and more energy-efficient than multiple-speed pumps.
  • A single-speed pool pump will also save you on energy costs, allowing you to save money on energy bills!
  • Single-speed pumps are less likely to cause premature motor failure, which is a great safety feature.
  • Single-speed pool pumps are not as expensive or difficult to install as they sound.
  • They do not require you to change the head and motor on your pool pump as often as traditional double-speed pumps do.
  • They’re not really “energy-efficient” because they require you to push more water than if you used a variable-speed pump.
  • Single-speed pool pumps are great for reducing noise, power consumption, and carbon footprint.

Variable-speed Pool Pumps

Variable-speed Pool PumpVariable speed pumps are either single-speed or multistage, with multistage pumps having two or more speed settings. This is an important factor to consider as a user will not be able to adjust the flow rate through the circulation system to accommodate their needs. For example, if you have a small pool that requires a lot of water flow, you will need to choose a variable-speed pump with a high flow rate.

What Makes Variable-speed Pool Pumps a Good Option:

  • Variable-speed pumps allow you to run the pump at a low speed for most of the day and then increase it to full speed when it gets really hot.
  • These pumps can be controlled remotely.
  • With variable-speed pumps, you can increase or decrease your flow rate at any time, which means less time spent standing around.
  • Variable-speed pumps are more expensive than fixed-speed models, but they are much more powerful and reliable.
  • Variable-speed pumps are a perfect choice for outdoor installations because they are much less likely to cause water damage if you accidentally leave them on overnight.
  • A variable-speed pump is also a great choice for pools that are used infrequently.
  • Variable-speed pumps are quieter and less noticeable to others.
  • Variable-speed pumps come in a variety of sizes, from the smallest 3hp model to the largest 4-ton model.

Variable Speed Pool Pump vs Single Speed

When choosing a pool pump, you have to consider several factors, including price, ease of installation, reliability, energy consumption, and warranty coverage. Here we discuss more details:


When you think of variable-speed pumps, you tend to think about the quality and reliability of the product. The good ones are usually known to be extremely reliable and durable. And since these can be used in different scenarios, they’re also known to be easy to install and use.

But there are some downsides too. Since they use a lot of power, they are not very efficient, so if you have to run it 24/7, they can drain your electricity bill quite quickly. Also, their motor runs at a constant speed, which may not be ideal if you need to use the pump at different speeds depending on the load.

A single-speed pump, on the other hand, has one speed that it can operate at. It’s much more efficient than a variable-speed pump, and it requires less electricity to run. In terms of reliability, they tend to last longer too, because the motor does not have to change gears.

So there are pros and cons for both types of pumps, but we think a single-speed pump is usually more reliable and efficient than a variable-speed one.

Energy savings

A good pump can save up to 70% of energy costs and help you avoid high electricity bills.

But what’s the difference between a variable-speed pool pump and a single-speed pump? What’s the best option for your pool?

The short answer is that both are pretty similar in terms of performance. So if you have a pool with a relatively small capacity, you may want to go for a single-speed pump.

If you have a larger pool, you may want a variable-speed pump because it can handle the demand better. It may also last longer, and it is more energy-efficient, as we explain here:

A single-speed pool pump has a fixed speed and will always operate at the same speed.

Variable-speed pool pumps are designed to adjust the speed based on the load. This means that they can operate more efficiently than a single-speed pump, which runs constantly at full speed regardless of the current demand. This can result in a better flow of water and a longer life for your pump.

Another important consideration when selecting a variable speed pump is how it’s rated – whether it’s rated at the maximum speed or at a low speed. Generally speaking, variable speed pumps with lower ratings are cheaper, but they may not be able to handle the load and may wear out faster.

So if you have a large pool, go for a variable-speed pump with a higher rating. If you have a small pool, go for a single-speed pump.

Upfront costs

The variable-speed pool pump is considered to be the best choice over a single-speed pump. While a single-speed pump will have a lower upfront cost, it will cost you more in the long run due to maintenance and replacement costs.

Variable-speed pumps are usually more durable and require less repair and maintenance, and they can last you much longer than single-speed pumps.

Cost savings

When it comes to the cost of installing a swimming pool, you may wonder if you can save money by getting a single-speed pump instead of a variable-speed pump.

The answer to this question depends on your needs and expectations, and how much you are willing to spend on your pool.

If you’re planning on doing some renovations in the near future and want to get your pool up and running as quickly as possible, it might be worth investing in a single-speed pump.

This is because single-speed pumps are generally faster than variable-speed pumps, which means that you can start enjoying the benefits of your new pool sooner. On the other hand, if your goal is to have a nice-looking pool, then a variable-speed pump is the way to go.

Technology Advancements

The water-pumping industry has been improving continuously, and so have the pumps used in swimming pools. With advances in technology, there has also been a corresponding increase in the variety of pumps available.

For example, most people are familiar with the traditional single-speed pump, but a newer type is known as a variable-speed pump. This type of pump can be set to run at a slow speed for long periods of time, while it runs at a high speed during brief bursts of activity. It allows the user to set the pump to run at a slower speed for maximum comfort, and at a higher speed when they need to work harder or jump in the pool.

The main advantage of a variable-speed pump is that it saves energy and helps to extend the life of the pump. It also means that you can set the pump to run at a slower speed for longer, which means you’ll save on your electricity bill.


Variable-speed pool pumps provide a smooth flow of water in the pool, even at low water levels. They can be adjusted to change the speed and volume of the water.

Single-speed pool pumps work with a single speed and do not adjust the speed. These are more powerful but require more maintenance than variable-speed pumps since they don’t have adjustable settings.

Here’s a comparison of variable-speed and single-speed pool pumps:

Feature Variable Speed Pool Pumps Single Speed Pool Pumps
Energy Efficiency More energy-efficient, can save up to 90% on energy costs compared to single-speed pumps Less energy-efficient, operates at a single, high speed that uses more energy
Cost More expensive upfront, but can save money in the long run due to energy savings and a longer lifespan Less expensive upfront, but may require more frequent maintenance and have a shorter lifespan
Noise Level Runs at lower speeds, resulting in less noise and a quieter pool environment Runs at a single high speed, resulting in more noise and a louder pool environment
Control Over Water Flow Allows for greater control over water flow, making it easier to maintain optimal water quality and chemical balance Limited control over water flow, which can lead to over-circulation and potential damage to the pool
Environmental Impact More environmentally friendly due to lower energy usage and greenhouse gas emissions Less environmentally friendly due to higher energy usage and greenhouse gas emissions
Pool Size Better suited for larger pools due to greater energy efficiency and longer lifespan May be sufficient for smaller pools due to lower energy usage and cost
Pool Usage Ideal for frequent pool use, as it is designed to run longer and more efficiently than single-speed pumps May not be ideal for frequent pool use, as it is designed for shorter periods of operation


It’s important to keep in mind that the variables of a pool’s design can dramatically affect its performance and efficiency. The main difference between a variable-speed pool pump and a single-speed pool pump is that the variable-speed pool pump allows the user to select from two speeds or even three or four speeds of operation, while a single-speed pump only allows the user to choose one speed. That’s because the variable speed pump is able to vary the flow of water through the pump at each speed.
