1. Turn Off the Heater

Before beginning the winterization process, ensure that the pool heater is completely turned off. This includes shutting off the power supply to the unit. Failing to do this can result in electrical hazards and damage to the heater.

2. Drain the Heater

Next, you’ll want to drain any water left inside the heater. Follow these steps:

1. Locate the drain valve on the heater.
2. Open the valve and allow the water to run out completely.
3. Open any additional drain ports that may be present on the heater to ensure no water is trapped.

3. Inspect and Clean the Heater

While the heater is empty, take this opportunity to inspect it for any signs of wear or damage. Clean the exterior and interior components to remove any debris, dirt, or algae that may have accumulated during its use. Pay particular attention to:

• The heat exchanger
• Filters
• Fan and motor components

4. Protect the Heater from the Elements

Once cleaned, it’s time to protect your investment from harsh winter conditions. Consider the following methods:

1. Cover the heater with a durable, weather-resistant tarp.
2. Secure the cover with a bungee cord or rope to prevent it from blowing off.
3. Avoid storing heavy items on the tarp, as this could damage the heater underneath.

5. Check the Pool’s Water Level

Maintaining the correct water level in your pool is important. Aim to keep the water level below the skimmer to prevent freezing and ensure that water does not enter the heater. If you need to drain additional water from the pool, do this carefully according to your pool's guidelines.

6. Cover the Pool

After winterizing your pool heater, it is wise to cover the pool itself as well. A quality pool cover can help to keep debris out and can minimize water evaporation, making spring opening easier.

7. Schedule a Professional Maintenance Check

If you are uncertain about any of the steps to winterizing a pool heater, consider calling a professional. They can ensure that your heater is properly winterized and ready for the next season.

By following these steps for winterizing your pool heater, you not only protect your investment but also ensure that it will be ready for use as soon as the swimming season begins again. Maintaining your pool and its components is key to enjoying a functional and fun swimming environment year after year.
