Pool Pumps and Motors are Getting Smarter and More Energy Efficient

Pool pumps and motors are no longer just devices to keep customers’ pools properly filtered. Rather, they are SMART, energy efficient, eco-conscious and can be connected to whatever automation the homeowner has available.

Want to turn on the hot tub before you leave work so the water is nice and toasty when you get home? Check. Monitor chemical levels remotely? Check. Get alerted if you left the pool lights on last night? Check.

Advanced pool technology is becoming so commonplace that it’s easy to forget that just a few decades ago, life – and swimming pools — were managed very differently. And that motors and pumps were not very energy efficient.

This article looks at how far the industry has come in terms of technology and provides guidelines on how and when to best integrate high-efficiency pumps and motors into customers’ pool systems.

A Look Back

Pool ownership in America soared in the 1980s and 1990s as homeowners began discovering that a swimming pool significantly increased the value of one’s home. Plus, pools offered fun, relaxation, and socializing opportunities.

Single speed pumps to circulate the water were dominant during this time frame and more than 60% of the replacements made by the pool service professional were motor replacements to get their customers back up and running.

Standardization of pumps and motors came together as manufacturers developed standard mounting configurations between the wet-end and the motor.

A Focus on Efficiency

In the 2010s, the market was driven by energy efficiency regulations and technology improvements. The market shifted from single-speed motor powered pumps and introduced the variable speed pump and to a lesser extent, the variable speed motor which powers the pump. These variable speed pumps and motors allow pool professionals to adjust motor speed based upon need which dramatically reduces energy consumption as both motor and pump manufactures tout energy savings potentials of 80% or higher.

Efficiency regulations greatly influenced the adaptation of these higher efficiency products with California’s Title 20/24 leading the way. ENERGY STAR®-certified pumps also materialized during this decade and this widely known recognition advised consumers that they are purchasing or installing an energy efficient pump. In this decade, the market participants created smarter, quieter and more energy efficient pool pumps and motors. Users and pool service professionals became more aware, and pool professionals led the charge of educating homeowners regarding these energy efficient products.

Variable Speed and Pool Control Systems

The current decade begins with the DOE’s 2021 regulation requiring most in-ground pool pumps to be variable speed. The market has shifted in this direction as these pumps are more energy efficient but now, many, when connected to PCSs, offer Wi-Fi connectivity. Pool Control Systems are becoming very popular too, and these PCSs integrate with homeowners’ SMART home systems therefore integrating the backyard with the SMART home.

With the new technology, a homeowner can control schedules, motor speeds, heaters, lights, and chlorinator settings from their smart phones. PCSs also allow for the pool service professional to better control water chemistry and create enhanced safety features such as alarms that alert homeowners if someone is in the pool, or alerts the homeowner should chemicals be out of balance or if the filter needs to be cleaned.

Utility companies have also joined in as they are implementing demand response programming where they may adjust pool equipment energy loads during peak hours to avoid strains on the power grid. California utility companies are leading the way with demand response systems as this state often has blackout issues and therefore the need to reduce energy consumption when the potential for a power outage arises.

In September 2025, the DOE implemented a rule to require pool replacement motors to be variable speed, similar to the 2021 rule for replacement pumps. This is a positive for the industry and the environment as pool professionals will replace almost all failed pumps and motors on in-ground pool pumps with energy-efficient variable speed equipment.

Motor manufacturers are also making their new variable speed motor products versatile enough to communicate with PCSs, connect with existing time clocks, or operate completely on their own. Whichever manner pool service professionals wish to manage pump and motor operation, today’s products can accommodate. They simply need square flange and C-flange variable speed motors on their trucks, and they can feel confident they will have an energy efficient, SMART replacement product for any pump they encounter.

When to Replace a Motor or Pump

Because variable speed pumps and motors allow users to adjust motor speed based upon need, this dramatically reduces energy consumption as both motor and pump manufactures tout energy savings potentials of 80% or higher.

Pool servicers can help customers save on energy costs by installing new equipment. However, for financial reasons some customers may prefer to delay replacement of either the pump or the motor until failure.

To help guide customers on this decision, pool servicers need to be aware of when to replace just the motor or the entire motor-pump assembly. Many factors play into this decision, including age of the equipment and visible signs of damage such as corrosion or cracks.

Any pump more than 10 years old should be replaced. Other reasons to replace include:

• The pump housing is cracked or is leaking water
• Corrosion and discoloration are visible on the wet-end. This likely indicates internal damage and it is time for a replacement
• The pump is frequently losing prime. This indicates air and/or liquid leakage
• The wet-end is making loud noises. This could indicate misalignment inside the pump end
• If the cost of the replacement motor is more than two-thirds of the cost to replace the complete pump, it is recommended to purchase the complete pump assembly

Replacing the motor only

This option can be chosen under these circumstances:

• The customer is on a budget. Generally, a motor replacement plus an installation kit is the lowest cost option for the homeowner and no replumbing work will be required
• The pump housing or wet-end is intact with no leaks or cracks
• The motor is making noise or will not start. Bearings or capacitors fail, causing grinding or screeching noises
• The pump is relatively new. If the pump end is less than 10 years old, replacing only the motor is generally the smarter and more cost-effective option
• The homeowner may wish to simply upgrade their motor to a new variable speed motor. Pool pros can confidently advise the homeowner they will achieve all the energy savings associated with variable speed by upgrading the motor only

For pool servicers, contractors, and pool product manufacturers, this is an exciting time to be in the pool industry, as technology continues to evolve and provides better energy efficiency and even more options to enjoy the backyard pool.
