How to Prevent Major Problems with Your Pool Heater


Having a pool can be an absolute joy. You can cool off in the summer, enjoy fun and recreation with your family and friends, and make sure your children are safer because they have learned to swim. But in Illinois, you wouldn’t get nearly as much enjoyment from your pool if it didn’t have a heater to keep the temperature comfortable. How can you make sure your pool heater will work exactly as it should and keep your pool warm and ready for fun? We’ve got some recommendations for you.


Like any piece of heating or cooling equipment such as a furnace or air conditioner, your pool heater needs to be checked on regularly by a professional. A technician in pool heater repair in Plainfield, IL can inspect, clean, and fine-tune your pool heater so it’s in tip-top shape. This should be done every year, and as springtime approaches, it’s the perfect season to schedule this maintenance. Having this done can drastically reduce the likelihood that you’ll need repairs done during the summer.

Filter Cleaning

Your pool heater contains a filter that prevents contaminants from circulating through the filter and causing a problem. However, if the filter becomes clogged, it can prevent the correct amount of water from passing through. Without sufficient water pressure, your heater won’t be able to work. The filter should be cleaned every month while the pool heater is in use.

Address Concerns Promptly

Any time you suspect a problem with your pool heater, you should schedule repairs as soon as possible. A minor problem is often an easy fix, but if you continue to operate a struggling pool heater without getting it repaired, the problem can become much larger. Keep an eye out for any signs that something is wrong, such as these.

  • Insufficient Heat: While the clogged filter mentioned above can prevent the heater from working well, if you’ve cleaned the filter and you’re still having problems, it’s time for repairs. It’s possible that there’s a problem with the fuel source. As most pool heaters use gas, a clog or leak in the gas line can compromise the flow of fuel and prevent the pool from heating. This is a problem that requires a licensed, qualified technician, and because fuel leaks can be dangerous, you should get help right away.
  • Corrosion: If you notice that your pool heater is developing rust or becoming corroded, you should have a technician take a look at it. This is most likely to occur with a pool heater that is more than ten years old. Having prompt repairs could mean salvaging the heater and only needing to replace certain parts. Allowing the corrosion to continue will mean needing to replace the whole thing.

We also recommend that you schedule an annual maintenance visit to inspect and tune up the pool heater. The best time to arrange for this service is in early spring, right before you start using the pool again. You can depend on our trained team of pool heating professionals for any service you may need.

If you have any questions or concerns about your pool heater, we’d love to hear from you.
