In short, saltwater pools can be heated just like any chlorinated pool. In fact, you can use the same heating methods, including gas, propane, electric, solar, and heat pumps. These pool heaters can be attached to saltwater pools the same way they would be attached to chlorine pools.

By heating your saltwater pool, you can extend the pool season while still enjoying a comfortable water temperature. If you’re interested in learning more about how saltwater pools are heated, read on! Below, we’ll cover the details on how to heat saltwater pools, and why saltwater pools should be heated.

Can Saltwater Pools Be Heated?

Heating your swimming pool is crucial if you want to enjoy a warm water temperature throughout the year. By having a heated pool, you can extend the swimming season by several weeks or even months. If you’re like many pool-owners who have converted to a saltwater pool, you may be concerned about how to properly heat it. Fortunately, there is no reason for pool owners to worry about heating a saltwater pool.

Heating a saltwater pool is quite similar to heating a chlorine pool. You may even use the same heating methods on your saltwater pool as you would on your chlorine pool. Simply attach the heating device to the pool system in the same manner as you would with chlorinated pools.

Although saltwater pools and chlorine pools have their differences, they also have many similarities. Because they both operate in similar ways, they both have the ability to be heated by a variety of pool heaters.

If you’re still unsure how to heat a saltwater pool, have no worries! Below, we’ll take a closer look at how hot saltwater pools should be, as well as the benefits of heating your saltwater pool.

How Hot Should I Keep My Saltwater Pool?

A common question many pool-owners ask is how hot a saltwater pool, or any pool in general, should be heated. Finding an ideal temperature for your pool is important to increase comfort and keep your pool safe to swim in.

Ideally, saltwater pool temperatures should be between 78°F and 82°F. This temperature range creates a safe, comfortable environment for swimmers of all ages to swim in. If you live in a warmer or cooler climate, you may slightly adjust the water temperature to fit your needs.

Similar to chlorine pools, it’s important to keep saltwater pools at an ideal temperature. Certain temperatures can create dangers to at-risk individuals, as well as make your saltwater pool vulnerable to contaminants. Additionally, water temperatures too hot or too cold can make the pool uncomfortable to swim in.

Maintaining a comfortable pool temperature is a fairly simple process. Simply set your pool heater’s thermostat to the desired temperature for your pool. If the thermostat isn’t accurate enough, you may use a pool thermometer to measure pool water temperature.

What Pool Heaters Should I Use On My Saltwater Pool?

As we mentioned earlier, saltwater pools can be heated in the same way as chlorine pools. Here, we’ll break down the three most common heating methods for saltwater pools.

  • Solar. If you’re looking for an inexpensive option for heating saltwater pools, solar heaters may be the ideal method for you. If you aren’t ready to invest in large solar systems, you may consider using solar blankets. Once again, solar blankets are inexpensive and are an excellent option for trapping heat. 
  • Electric heat pumps. Although electric heaters can be expensive to run, they are long-lasting and very efficient in heating saltwater pools. Additionally, they are easy to install, making them an ideal option for saltwater pools.
  • Gas. Once again, gas heaters can be expensive to operate, but they are effective for heating saltwater pools. If you’d rather not use gas, you may use propane heaters as an alternative.

No matter which heating method you use, heating a saltwater pool is a simple process. Once your heating pump is installed, you may set the thermostat at a temperature that best suits your needs.

Is It Necessary To Heat A Saltwater Pool?

Another question that may come to mind when determining how to heat a saltwater pool is why saltwater pools need heating in the first place. While it may appear that heaters are for luxury purposes only, they can improve your swimming experience in ways you may not be aware of.

There are many reasons to heat a saltwater pool, both during the warm seasons as well as the cooler months. First, heated saltwater pools extend the swimming season by several weeks. In fact, you may still be enjoying your pool during the late autumn season.

Second, heated saltwater pools create a safe environment for individuals to swim in. When water temperatures are extremely cold, swimmers may suffer from shock when they enter the water. Additionally, chemicals may not work as well in cold pool water. Because chemicals must be properly balanced in order for pool water to be safe, it’s important to keep saltwater pools at a safe, heated temperature.

Third, too cold of water can damage equipment in saltwater pools. For instance, the salt chlorine generators may stop working when temperatures become too low. For this reason, it’s important to heat saltwater pools.

Finally, heating saltwater pools improve your swimming experience by creating a warm, comfortable environment. By heating your saltwater pool, you can enjoy every minute of swimming in your pool, regardless of the season.

Final Thoughts on Heating Saltwater Pools

In summary, heating a saltwater pool isn’t only optional, but it is important for pool maintenance. Heating a saltwater pool ensures water temperatures are always comfortable and safe for swimmers. In addition, pool heaters extend the swimming season, allowing you to reap the benefits of a saltwater pool from spring through fall.
