Should I Get An Energy Efficient Pool Pump?

One of the most notable components in your home that consumes more energy, if you have a swimming pool, would be the pool pump. A pool pump performs the job of maintaining the cleanliness of your pool by circulating water via filters. Pool pumps are known to use up anywhere from 3000 to more than 5000 kWh annually. The use of energy differs based on several factors, such as energy rates, length of swimming season, temperature of the pool, and various other environmental factors. In addition, some of you may have pumps that circulate water through cleaners, fountains, heater, or water features. These pumps usually have a motor of 1 to 2 horsepower, running a minimum of five to six hours a day consuming a lot of energy. And most of these pumps happen to be single-speed pumps.

Single Speed Pool Pump Alternative

To answer the question whether or not you should get an energy efficient pool pump – yes, you should. If you have been looking for ways to reduce the consumption of energy by the pool pump in your home, then the best option for you would be to replace your single speed pool pump with a variable speed pump. A variable speed pump is known to reduce energy consumption by around 50 to 75 percent. The main reason behind this is that the pump is capable of reducing the motor’s rpm, which in turn brings down the use of energy.

A variable speed pump does an excellent job reducing the amount of watt drawn by matching the pump’s speed to the action being performed. Replacing your single speed pool pump with a variable speed pump is also simple and quick. The service offered by this pump will be the same as what you received from your traditional pump, except for the fact that you will be able to enjoy substantial energy savings.

Performance and Cost

Replacing your single speed pool pump with a variable speed pump will deliver greater energy savings than you expect.

Energy Consumption of Single Speed Pumps

the entire course of swimming pool operation, the pump performs different water circulation tasks. Despite the fundamental duty of a pool pump being the circulation of water via the filters, it is often used for various other purposes such as filter backwashing, water supply to the pool sweeper, impelling spa jets, water circulation through heater, and more. Such tasks typically require more energy than the regular task of circulating water through the filters and therefore lead to increased energy consumption.

Single speed pumps have to be of the right size in order to carry out some of the demanding tasks mentioned above. Now this simply means that the pumps mostly provide excessive circulation than what is originally required by the filtration system in your pool.

Benefits of Variable Speed Pumps

A variable speed pump would be a great investment in the long run and will help you save hundreds of dollars annually. With a variable speed pool pump, you will be able to achieve the perfect filtration flow rate along with significant reduction in energy consumption. This is because these pumps use Permanent Magnet Motors (PMM), which, as the name implies, are known to make use of permanent magnets to establish a magnetic field between the windings and the rotor. To perform the same process standard motors require more electricity, which leads to higher energy consumption.

The PMM motors used in variable speed pumps are capable of achieving 90 percent efficiency ratings, which is significantly higher than what can be achieved by standard motors (30 to 70 percent). There are many resources available online to help you calculate pool pump savings; the Residential Pool Pump Savings Calculator from Pentair is one such easy and useful resource.

Tips to Upgrade Your Pool Pump

Should I Get An Energy Efficient Pool Pump? Now that you know it is important to get an energy efficient pool pump for energy and cost savings, here are a few more tips to upgrade your pool pump:

  • When choosing a pool pump, be sure to choose a pump with the lowest wattage. For most residential pools a 750 watt pump will do the required job perfectly fine.
  • When you browse different pool pump models, you will be able to notice that each pump has a particular number of energy efficiency stars. The more stars a pump has, the more is its energy efficiency. Therefore, it is best to purchase a pump with at least a five star rating.
  • And as discussed earlier, go for a variable speed pool pump that comes with an automatic controller.

Getting an energy efficient pool pump can be a bit expensive initially; but it can be extremely helpful and help you lots of money in the long run.
