How to Reduce the Energy Consumption of a Swimming Pool

Almost everyone would love a swimming pool in his own backyard. Not only will a pool offer hours of excitement and pleasure most especially during the hot summer months, but will also add beauty and value to the property.

It is true that the many advantages of having a swimming pool somehow diminish the amount spent in maintaining a swimming pool. The constantly rising electricity rates have made it very costly to efficiently to run and keep a swimming pool.  Factors such as cleaning, filtration and heating define the amount of energy required to run a pool. Aside from electricity bill, additional costs include chemicals and other filtering equipment, and water the pool requires. Among the required pool processes mentioned, which of them use up the most electricity? Are there practical ways on how to reduce the energy consumption of a swimming pool for it to be cost-efficient and energy-efficient?

Energy-efficient Pool Filtration Pumps A couple sitting at the swimming pool

Water filtration pump consumes the largest electricity   in a pool set-up. Research indicates that up to 70% of a swimming pool’s energy consumption is attributed to pumps, accounting for   about 16% of the total electric bill of one standard household. In this connection, it makes sense to choose energy efficient pool pumps. Global warming and climate change has paved the way for the development and production of energy-efficient products. There are pool pump products that are star rated from 1 to 10 by the energy regulatory board, with each star corresponding to a 25% increase in efficiency. The more stars, the better for saving energy.

The use of smaller and higher efficiency pool pump requires less than 30% to 45% energy to operate. Efficient pumps come in variable speeds, like two-speed and four-speed, thus you can turn down the pump speed for regular cleaning, and set it to a higher setting for less frequent but more thorough cleaning. Energy-efficient pumps also circulate water more effectually, thus needing less filtration.

Pool Cover

About 95% of a swimming pool’s heat loss occurs at the surface through evaporation, and radiation. A pool cover is not only for safety purposes, but for the prevention of heat loss, water loss, and maximizing the efficacy of pool chemicals. A pool cover of pool blanket may be retractable or not. It protects the pool from the elements such as the wind and sun. The less direct UV rays hitting the pool’s surface mean less chemical maintenance for the pool water. The less debris and particles in the pool, the less filtration, vacuuming and skimming required.

A solar pool cover also helps heat the water of the pool, so there’s less need to use a heater to keep the pool water warmer across all seasons. Research indicates that by using a solar pool cover, energy consumption for heating is lessened by 50 to 70%. The amount of water to be periodically added to the pool is lessened by 30 to 50% too, while chemical use is reduced by 35% to 60%.

Heating and Water Temperature Efficacy

Heated pools are ideal when the colder months are up. It is easy enough to imagine that heating thousands of liters of water can cost a lot in terms of energy consumption. Aside from using a functional and efficient solar pool cover, it is also possible to save money on heating by heating the pool only when needed.  If the heater has a passive heating capacity to keep the pool warm for a longer period of time, it is best to switch this off. Turning down the temperature of the heater will also save on energy consumption. The ideal pool water temperature is from 78 to 84 Fahrenheit.

The location of the pool will help maximize the use of solar energy in warming the water. The installation of screens or other structures to deter prevailing winds will also keep the water warm for a longer period of time. Solar energy is the most cost-efficient method of heating a pool. If this is not possible the use of energy-efficient gas or electric heaters is recommended.

Use automatic pump and pool heater timers to facilitate running them in short cycles. This will be more cost-efficient than running them continuously for long hours every day.

Additional Energy Efficiency Tips A woman in the swimming pool

There are more ways to save money pertaining on energy costs of swimming pools. It is possible to make them more energy efficient.

Doing the required daily pool maintenance efficiently will lessen energy consumption. When the pool is not in active use, turning off the filtration and heating systems saves money.

If the use of pool heater is a must, maintaining the suitable water temperature must be observed. The recommended temperature for active swimming is from 78 to 80 degrees Fahrenheit (25 to 27 Celsius); and for recreational swimming 82 to 84 degrees Fahrenheit (27 to 29 Celsius). It is best to keep a thermometer near the pool to get the water temperature, and mark the most comfortable setting on the dial.

Save water and energy by backwashing the pool filter only when necessary. Keeping the drain system free from debris and particles will facilitate the free flow of water. Clogged drains require more pump power. Circulating water through the filter once daily is enough as additional cycles are wasteful.

Running the filtration system during off peak hours saves on electric bills as electricity demand is lower. Using energy efficient pool lights, such as solar powered and LED lights will cut energy consumption.

How to Keep Swimming Pool Water Clear

There are many advantages of having a swimming pool in one’s backyard. Aside from providing hours of fun and entertainment, a swimming pool also provides a means for low impact aerobic exercise (swimming) and other pool-based workout activities. A swimming pool beautifies one’s home, even adding to its market value. But maintaining a swimming pool is not a breeze.   Swimming pool water can quickly turn cloudy, hazy or green if ill-maintained.

Why does swimming pool water turn cloudy or green? Are there standards and easy-to-do solutions on how to keep swimming pool water clear?

Causes and Solutions for Cloudy or Green Pool Water

A Woman in a Swimming Pool

Lack of Chlorine

Even a well-maintained swimming pool can turn cloudy or green overnight. There are three common reasons why this happens. First, the free chlorine in the pool is depleted after constant, heavy use. Second, heavy rains will ultimately dilute the chlorine in an outdoor pool. And third, intense UV light can also deplete then pool’s free chlorine. Remember the diving, synchronized swimming and polo pools at the 2016 Rio Olympics? They turned emerald green because hydrogen peroxide, which is a de-chlorinator, was added to the pool’s water as part of maintenance.  Note that green pool water usually means algae in the water.

Solution: If the swimming pool water is cloudy or is green due to lack of free chlorine, the quickest solution is to shock the pool.  Shocking a pool means super-chlorinating the water. Factors such as the size of the pool, how green or cloudy the pool is, and even the type of filter are considerations. For pools with cartridge or sand filters, liquid chlorine is highly recommended. For a swimming pool that has a Diatomaceous Earth (DE) filter, granular chlorine is best.  Before shocking the pool water, its pH should be around 7.2 as its level will rise after shocking.

The pump should be on for at least 24 hours for the water to turn cloudy blue or blue. However, shocking the pool water will not clear up a cloudy or green pool if there is no pool filter. A clarifier solution need not be added if the pool is properly filtered. In some instances a flocking agent can be used to bind together small particles (algae) together, sink them to the bottom of the pool, then vacuumed up.

It is recommended to test and adjust the alkalinity and pH levels of the pool water 24 hours after shocking. The chlorine level would still be high, but this will stabilize after a few days.  For maintenance purposes and for crystal clear water, super chlorination the pool water weekly is recommended.

Imbalanced or Improper Pool Chemical

Maintaining the correct level of pool chemicals is a very important step in keeping the water clear and free from algae. Adding an incorrect amount or using the wrong chemical are two major causes of cloudy or green water.

Total alkalinity (TA) must also be monitored as high TA may cause calcium and pH scaling which in turn contribute to water cloudiness.

Accumulated bromine, phosphate and cyanuric acid (CYA) in high levels may contribute to pool water cloudiness. The free chlorine and CYA in the water must be balanced as high level of CYA reduces free chlorine.

Solution:  There are water testing kits available to efficiently and correctly measure the pH and chlorine levels of pool water. An ideal pH level should be between 7.2 and 7.6. If the swimming pool pH level is high, adding acid such as sodium bisulphate or muriatic acid to the water will lower it. If the pH level is low, adding alkali such as sodium carbonate will balance it. Total alkalinity must be between 80 ppm to 120 ppm to avoid scaling.

The ideal chlorine level is 3 parts per million (ppm). If the chlorine level is low, add chlorine. Chlorine stabilizer such as cyanuric acid will prevent depletion of chlorine due to UV exposure.  However, as mentioned earlier, too much CYA will leave the pool water cloudy and highly at risk of forming algae.

Poor Filtration and Water Circulation Systems toy ship swimming pool

If the pool’s filtration system is faulty, or if it is not running at least 8 hours a day, then the pool water is likely to be cloudy. The pool filtration system’s purpose is to continuously “filter” or clean pool water to make it crystal clear. Poor water circulation system will also cause improper water circulation, making the pool water stagnant and cloudy.

Solution: There are a few points that need to be exact for the filtration and water circulation systems to work well. First, the circulation system, including the pump size, should be in synch with the pool’s size and design. The return or eyeball fitting must point down so that the water at the pool’s bottom will circulate properly.

Ideally, the pool filtration system should be running on a 24/7 basis more so during heavy use for the water to be clear. However, home swimming pools that are not used heavily would thrive on 8-10 hours of filtration. Particles that could be blocking the filter should be removed. Blocked filters will not properly function. Regularly cleaning and backwashing the pool are required for clean and clear pool water. Replacing DE and cartridge pool filters should be done when needed.

Environmental Factors

People, structures, animals, birds, trees and other foliage, sun, rain, wind and other environmental factors can affect the clarity of pool water. Direct UV rays will deplete the pool’s free chlorine; but if trees or structures block direct sunlight, then free chlorine level will not be affected.

Rain (fresh water) can affect the free chlorine level of pool water. After heavy rains, it is best to test the chlorine level of the pool.

Pollen, blown foliage and other particles may land in the pool water. Sunblock and other body oil used by swimmers may accumulate in the pool, causing cloudiness.

Solution: Skim and vacuum the swimming pool as needed. It is best to use a cleaning net to skim the pool for particles, and empty the skimmer basket. It is best to use an efficient pool vacuum to clean the bottom of the pool on a regular basis.
