How to Winterize a Natural Gas Pool Heater

Winterizing your natural gas pool heater is an important task to ensure that your equipment remains in good condition during the colder months. Here is a step-by-step guide on how to winterize your natural gas pool heater:

Step 1: Turn off the Gas Supply

Before you start winterizing your natural gas pool heater, make sure to turn off the gas supply to the heater. This can be done by turning off the valve that controls the gas flow to the heater.

Step 2: Turn off the Power

Next, turn off the power supply to the heater. This can be done by switching off the circuit breaker that controls the power to the heater.

Step 3: Drain the Water

To prevent any damage to the heater due to freezing water, it is important to drain all the water from the heater. This can be done by opening the drain valve at the bottom of the heater and letting the water drain out completely.

Step 4: Remove the Drain Plugs

Once all the water has been drained from the heater, remove the drain plugs from the heater. These are usually located on the header of the heater and the manifold. Make sure to keep these drain plugs in a safe place for future use.

Step 5: Clean the Heater

Before storing the heater for the winter, it is important to clean it thoroughly. This can be done by using a soft cloth and a mild detergent to clean the exterior of the heater. Make sure to remove any debris or dirt that may have accumulated on the heater.

Step 6: Store the Heater

Once the heater has been cleaned, it is time to store it for the winter. Make sure to store the heater in a dry and protected area. Cover the heater with a waterproof cover to protect it from the elements.

By following these simple steps, you can ensure that your natural gas pool heater remains in good condition during the winter months. This will help prolong the life of your equipment and ensure that it is ready for use when the swimming season starts again.
