Sharing is Caring


If you’re a pool owner, you know how important it is to maintain your pool equipment throughout the year. When winter comes around, protecting your pool heater should be at the top of your list. Cold temperatures and harsh weather conditions can cause damage to your heater, which can lead to expensive repairs down the line.

Winterizing your pool heater may seem like a daunting task, but it’s actually quite simple with the right knowledge and tools. In this article, we’ll provide you with easy tips on how to protect your pool heater during the winter months. By following these steps, you’ll ensure that your pool heater stays in good condition and is ready to use once the warm weather returns.

Before we dive into the tips, it’s important to note that different types of pool heaters require different winterization methods. In general, there are three types of pool heaters: gas, electric, and solar. Make sure to consult your owner’s manual or a professional to determine the specific steps needed to winterize your pool heater.

So, let’s get started on how to protect your pool heater during the winter!

Why winterizing your pool heater is important

Winterizing your pool heater is an essential part of pool maintenance, but why is it so important? Here are two reasons:

Prevent damage to your pool heater

Winterizing your pool heater can prevent damage caused by freezing temperatures and harsh weather conditions. When water freezes, it expands, which can cause your pool heater’s pipes to crack or burst. This can lead to expensive repairs or even the need for a complete replacement of your pool heater. By properly winterizing your pool heater, you can avoid these costly repairs and keep your pool running smoothly.

Extend the life of your pool heater

Properly winterizing your pool heater can also extend its lifespan. By protecting it from the harsh winter weather, you’re preventing unnecessary wear and tear that can cause it to break down more quickly. This means you’ll be able to enjoy your pool heater for many years to come.

How to winterize your pool heater

  • Drain your pool heater and disconnect any power sources
  • Remove any water from the heater’s components, including the pipes, pump, and filter
  • Add antifreeze to your pool’s plumbing system to prevent any remaining water from freezing

Call in the professionals

If you’re not confident in your ability to properly winterize your pool heater, it’s always a good idea to call in a professional. They can ensure that your pool heater is winterized correctly and give you peace of mind knowing that it’s protected from the winter weather.

Now that you know why winterizing your pool heater is important and how to do it, you can protect your pool heater and enjoy it for many years to come!

How to properly shut down your pool heater

Properly shutting down your pool heater is just as important as winterizing it. Neglecting to do so can lead to damage and costly repairs when you’re ready to use it again. Here are some tips to ensure your pool heater is safely shut down for the winter.

The first step is to turn off the power supply to your pool heater. This can usually be done by flipping the switch on the circuit breaker that controls the pool heater. Next, turn off the gas supply to the heater if it is a gas-powered heater. You can do this by closing the valve on the gas line that leads to the heater.

Draining the pool heater

The next step is to drain the pool heater of any remaining water. This is important because if water is left inside the heater over the winter, it can freeze and expand, causing damage to the heater. To drain the heater, first turn off the power and gas supplies as mentioned earlier. Next, locate the drain plug on the heater and remove it. Allow all of the water to drain out of the heater and leave the plug out until you are ready to use the heater again in the spring.

Cleaning and covering the pool heater

After draining the heater, it’s a good idea to clean it thoroughly. Use a soft-bristled brush to remove any debris or buildup on the heater, and wipe it down with a damp cloth. Once the heater is clean, cover it with a specialized pool heater cover that is designed to protect the heater from the elements.

Final tips

  • Check your pool heater’s manual for any specific shutdown instructions recommended by the manufacturer.
  • Make sure to turn off the power and gas supplies to your pool heater before beginning any maintenance or cleaning.
  • Consider hiring a professional to winterize your pool heater if you’re unsure about the process or don’t have the necessary tools.

By following these tips, you can properly shut down your pool heater for the winter and protect it from damage. Remember, proper maintenance and care of your pool heater can extend its lifespan and save you money on repairs in the long run.

What tools you will need for winterizing

Winterizing your pool can seem daunting, but having the right tools can make the process much easier. Here are some essential tools you will need:

Pool Cover

The first tool you will need is a pool cover. A pool cover will protect your pool from debris and prevent water from getting into the pool during the winter months. Make sure you measure your pool to ensure you purchase the correct size cover. A pool cover is essential for keeping your pool clean and well-maintained during the off-season.

Winterizing Chemicals

Winterizing chemicals are another essential tool you will need. These chemicals are designed to protect your pool from damage caused by freezing temperatures. They can prevent pipes and pumps from cracking due to ice formation. Using the right winterizing chemicals can save you from costly repairs in the spring.

Air Compressor or Shop Vacuum

  • An air compressor or shop vacuum is also important for winterizing your pool. You will need it to blow out the water from your pool’s plumbing system to prevent damage from frozen water. These tools can be rented from your local hardware store if you do not own them.
  • Another tool you can use to drain water from your pool’s plumbing is a submersible pump. It can be used to drain the water from your pool, and once it’s emptied, you can use the air compressor or shop vacuum to blow out any remaining water.

With the right tools, winterizing your pool can be a straightforward process that will save you time and money in the long run. Make sure you have all the tools you need before you start the process to avoid any delays or additional costs.

How to Drain the Water from Your Pool Heater

As the winter season approaches, it’s important to properly shut down your pool heater to prevent any damage from freezing temperatures. One crucial step in this process is draining the water from your pool heater. Here are some simple steps to follow:

Before you begin, make sure you have all the necessary tools on hand. You will need a garden hose, a pair of pliers, and a large bucket or drain pan.

Step 1: Turn Off the Heater

  • Turn off the pool heater to allow it to cool down completely before draining the water.

Step 2: Locate the Drain Valve

  • Locate the drain valve on the bottom of the pool heater. It will look like a spigot and should be near the water inlet and outlet pipes.
  • Attach a garden hose to the drain valve and route it to a nearby drain or large bucket or drain pan.

Step 3: Drain the Water

  • Using a pair of pliers, slowly turn the drain valve counterclockwise to open it and allow the water to begin draining.
  • Monitor the draining process to ensure the water is flowing steadily and not backing up.
  • Once all the water has drained from the pool heater, close the drain valve by turning it clockwise with the pliers.

Draining the water from your pool heater is a simple but important step in properly shutting it down for the winter. By following these steps, you can help prevent any damage from freezing temperatures and ensure your pool heater is ready to use again when the weather warms up.

Why you should cover your pool heater during the winter

Winter can be a challenging time for your pool heater. Freezing temperatures and moisture can lead to damage and corrosion, reducing the lifespan of your equipment. That’s why it’s essential to cover your pool heater during the winter months. A pool heater cover can help prevent damage caused by snow, ice, and other harsh weather conditions.

Here are three reasons why you should cover your pool heater during the winter:

Protects against moisture damage

Moisture is one of the biggest threats to your pool heater during the winter months. When water freezes, it expands, which can cause cracks and other damage to your equipment. A pool heater cover can help prevent moisture from accumulating on your heater and causing damage.

Prevents corrosion

Pool heaters are made from metal, which can be prone to corrosion. Exposure to moisture and salt can accelerate the corrosion process, leading to rust and other types of damage. A pool heater cover can help protect your equipment from these damaging elements, helping to extend its lifespan.

Saves energy and money

Covering your pool heater during the winter can also help you save energy and money. When your heater is not in use, it can lose heat to the surrounding environment. A cover can help trap the heat inside, reducing energy consumption and saving you money on your utility bills.

How to troubleshoot common pool heater problems

If you’re a pool owner, there’s nothing more frustrating than discovering your pool heater isn’t working properly. Before you call in a professional, there are a few things you can check yourself to troubleshoot common pool heater problems.

The first step is to identify the problem. Is the heater not turning on? Is the water not getting warm enough? Is the heater making strange noises? Once you’ve identified the problem, you can move on to troubleshooting.

Check the power source

If your pool heater isn’t turning on, the first thing to check is the power source. Make sure the heater is plugged in and that the circuit breaker hasn’t tripped. If the power source seems to be working, move on to the next step.

Inspect the filter and pump

If your pool heater is turning on but the water isn’t getting warm enough, it could be due to a clogged filter or malfunctioning pump. Inspect the filter and pump to make sure they’re working properly and free of debris. If you find a clog, clean or replace the affected component.

Check the thermostat and pressure switch

If your pool heater is turning on and the filter and pump are working properly, but the water still isn’t getting warm enough, check the thermostat and pressure switch. The thermostat regulates the temperature of the water, while the pressure switch ensures the heater doesn’t overheat. Make sure both components are functioning correctly and adjust as necessary.

When to call a professional to service your pool heater

Pool heaters can be complex systems that require regular maintenance and occasional repairs. While some issues can be resolved by the homeowner, there are certain situations that require the assistance of a professional. Here are a few signs that it’s time to call in an expert:

No Heat

If your pool heater is not producing any heat, it could be due to a variety of issues such as a malfunctioning thermostat, pilot light, or pressure switch. Attempting to diagnose and fix these issues on your own could lead to further damage and safety hazards. It’s best to have a professional inspect and repair your pool heater.

Strange Noises

Unusual noises such as banging, screeching, or rattling coming from your pool heater may indicate a serious problem. These noises could be caused by anything from a damaged fan to a blocked air intake. A professional can determine the cause of the noise and make the necessary repairs.

High Utility Bills

If your utility bills have suddenly skyrocketed, it could be due to an inefficient or malfunctioning pool heater. A professional can inspect your system and determine if it needs to be repaired or replaced. It’s important to address these issues promptly, as an inefficient heater can lead to wasted energy and money.
