How to Maintain a Natural Gas Pool Heater

Keep Your Pool Heater Running Efficiently with These Natural Gas Maintenance Tips

If you have a natural gas pool heater, it's important to keep it maintained so that it operates efficiently and safely. Here are the steps to follow for maintaining your natural gas pool heater:

1. Turn off the gas supply: Before beginning any maintenance work on your natural gas pool heater, make sure to turn off the gas supply to the heater. This can typically be done by turning a valve near the heater.

2. Clean the heater: Use a soft brush or cloth to clean the exterior of the heater. This will help remove any dirt or debris that has accumulated on the surface. Be sure to also clean the area around the heater to prevent any debris from getting inside.

3. Check for leaks: Inspect the gas connections and fittings for any signs of leaks. You can do this by applying a solution of soap and water to the connections and looking for bubbles. If you detect a leak, turn off the gas supply and contact a professional to repair it.

4. Check the pilot light: Make sure the pilot light is burning steadily and is blue in color. If it is flickering or yellow, it may be a sign of a problem and should be inspected by a professional.

5. Inspect the burner: Remove the burner and clean it with a soft brush or cloth. Make sure there is no debris or buildup on the burner. If you notice any damage to the burner, it may need to be replaced.

6. Check the heat exchanger: Inspect the heat exchanger for any signs of corrosion or damage. If you notice any issues, contact a professional to repair or replace the heat exchanger.

7. Replace the filter: Replace the filter in your pool's filtration system. A dirty filter can cause your heater to work harder and less efficiently.

8. Turn on the gas supply: Once you have completed all of the maintenance steps, turn the gas supply back on to the heater.

By following these steps, you can help ensure that your natural gas pool heater operates efficiently and safely throughout the swimming season. Remember to always consult a professional if you notice any issues or have any concerns about your heater.
