Are you having trouble with your gas pool heater? You’re not alone. Many pool owners experience similar issues, so don’t despair. In this article, we will give you tips and tricks on troublshooting your gas pool heater so you can get back to enjoying your swimming pool.
1. Check the Supply of Gas and Pressure
Before you begin troubleshooting, it is essential to check the gas supply and pressure. To check the gas supply, make sure your supply line is open and the gas is coming into your pool heater. You can do this by turning on the gas valve on the main supply and listening for a hissing noise. If the gas supply is good, it is important to make sure the pressure to the heater is not too low. Low pressure will reduce combustion efficiency, resulting in inadequate heating, or no heating at all.
Check Gas Valve Openings
To ensure the pressure is good, check if each gas valve between the pool heater and the gas supply is completely open, or whether they need to be slightly adjusted to increase the gas flow. If the gas valves are adjusted correctly, turn the pool heater on and after a few minutes, check the pressure again with a gas pressure gauge.
Check the Size of the Gas Line
It is very important to ensure the size of your gas line is the correct type for your pool heater. Your pool heater may need a larger gas line than the one currently connected for sufficient gas pressure.
2. Check the Gas Connection
Once you have checked the gas supply and pressure, examine the gas connection between your gas pipe and your pool heater. Over time, any gas connection can become loose or corroded. Therefore, it is important to check the connection regularly for any signs of wear and tear.
Inspect for Gas Leaks
Another issue that can occur is gas leaks. To check for any, you will need to inspect the valves, the burner, and the fuel line to ensure they are tight, secure, and in perfect condition. If any gas seems to be leaking, try to tighten the connection first, and if that doesn’t work, contact a professional to have it taken care of.
Check the Burner
As part of your troubleshooting checklist, make sure to check the burner. When you turn on the pool heater, look inside to check the flame. It should be burning a steady blue flame; any red or yellow flickers are signs of trouble. If you notice any signs of trouble, turn off the pool heater and contact a professional to investigate.
3. Check for Overheating
If your pool heater is not heating at all, it could be due to overheating. This often occurs when the pool heater is not being used for long periods of time, or if the pump is not circulating the water around the heater efficiently. To fix an overheating problem, it is important to switch off the pool heater and identify the cause of the issue.
Clean out the Filters
If the filters on your pool have become clogged or dirty, this can cause the water to become blocked and result in the heater overheating. The best way to remedy this is to clean out the filters and ensure that the pump is circulating the water correctly.
Check the Pool Heater Thermostat
When troubleshooting an overheating problem, you should also check the thermostat on your pool heater. If it is set too high, it can cause the pool heater to overheat. Try resetting the thermostat to a lower temperature.
4. Check for Insufficient Heating
Inadequate heating is often caused by a lack of gas or low pressure, air in the pool heater, the thermostat being set too low, or the filters being clogged or dirty.
Check the Gas Supply
If the gas flow is too low, it will result in inadequate heating. Check that the main gas supply is open and that the gas valves are adjusted properly. If the pressure is low, you may need to adjust the valves to increase the pressure.
Inspect for Air Leaks
If the pressure is good, inspect the pool heater for any air leaks that can cause pressure to drop. Look for signs of wear and tear in the air lines, between the air ducts, and the burner. If any leaks are found, contact a professional for repair.
