In Florida, we enjoy our pools year-round, but especially in the summer months. With the kids off from school, your backyard is the perfect place for a pool party — except if your pool isn’t working properly. The number one issue we at Jupiter-Tequesta see with customers’ pools concerns their heater. 

4 Signs Your Pool Heater Needs Repair

Read on to see if these warning signs match your pool’s current condition:

1. Your Heater Won’t Ignite

If your pool heater isn’t igniting, there are a few different possible issues:

  • Your heater isn’t turned on and the temperature isn’t set correctly. Make sure the thermostat is set high enough for the heater to kick in. This means the temperature should be higher than the current water temperature in your pool.
  • Your pump isn’t running with a clean filter and basket. A clogged or broken filter can lead to other problems with your pool. Check the pump and filter and clean it if necessary.
  • Your pilot light isn’t lit. Check the gas pressure, air supply, and venting in your pool. Make sure the pilot tube is intact, tightened, and not clogged.
  • Your gas supply valve is off. Be sure that your supply valve is in the ON position. Without gas, the heater won’t operate.
  • The filter valves aren’t open. Make sure your valves are open in order to ensure a constant flow of water.

2. Low Water Flow

To ensure your heater is operating efficiently, your pool needs to maintain a consistent flow of water. Most swimming pool heaters have built-in sensors that allow you to monitor and detect changes in water flow. You may see a ‘Low Water Flow’ warning, or notice the heater isn’t pushing out enough warm water.

3. The Heater Turns On and Off

If your heater is cycling ON and OFF, this is an indication that there’s an electrical issue with your pool. This may not always be the case, but calling your electrician is the safest bet. Your electrician will check a few different variables. These may include:

  • Checking your pool water chemistry.
  • Inspecting your pressure sensor, thermal regulator, or high limit switch.
  • The last time you inspected your heat exchanger.

4. The Pool Isn’t Heating

Your pool heater may still be igniting, but the water just doesn’t seem to heat up to the desired temperature. Or, your heater may not be producing heat at all.

These scenarios are both very common. After checking your settings, inspecting your sensor, and cleaning your filter, if your pool heater still isn’t working, it’s time to call in some help.
