Warm Goodbyes: The Ultimate Guide to Winterizing Your Pool Heater

As the sun-kissed days of summer fade and cooler winds blow in, every pool owner knows it’s time to prep for the off-season. While you might be adept at winterizing your pool, your pool heater – the unsung hero that’s provided you with countless warm swims – needs special attention. Here’s how to ensure it braves the chill and is all set for the next dive season.

1. Why Winterize Your Pool Heater?
Your pool heater is a significant investment and susceptible to damage from frost and freezing conditions. Winterizing it protects the internal components from expanding ice, potential cracks, and ensures its longevity.

2. Steps to Ensuring a Toasty Pool Heater Through Winter:

• Turn It Off: Begin by turning off the pool heater at the circuit breaker. This ensures safety while you proceed with the winterization process.
• Cool It Down: If you’ve been using the heater, let it cool down completely. This can take several hours, so be patient.
• Gas Heaters: If you’re using a natural gas or propane heater, turn off the gas supply. It’s vital to ensure no gas leakage occurs during the colder months.
• Disconnect & Drain: Disconnect the heater from the plumbing system. Open all drain valves and remove any drain plugs to let out any remaining water. Remember, even a small amount of water can freeze and cause damage.
• Blow Out the Lines: Using a shop vac, blow out any residual water from the inlet and outlet lines. This step is crucial as water left in the lines can freeze, expand, and crack the heater exchanger.
• Cover Up: While many pool heaters are built to withstand the elements, covering them can prevent dirt, debris, and especially snow accumulation. Use a breathable cover to avoid condensation buildup, which could lead to corrosion.
• Check the Manual: Different heater models may have specific winterizing instructions. Always refer to the manufacturer’s manual to ensure you haven’t missed any model-specific steps.

3. Pro Tips for Winter Love:

• Inspections Are Key: Before winterizing, inspect your heater for any existing damage or issues. This off-season is an excellent time for repairs, ensuring a smooth start come spring.
• Avoid Fully Sealing: When covering your pool heater, avoid sealing it too tightly. Allow for some airflow to prevent condensation and mildew growth.
• Winter Checks: Even during the off-season, periodically check your pool heater for signs of pests, which might consider your heater a cozy winter home.

Conclusion:
Giving your pool heater the winter care it deserves ensures that when the sun’s out again, you’re ready for those perfectly warm swims. As with most things in life, a little prevention goes a long way, and with these steps, you’re not just saying goodbye to your heater for the winter; you’re ensuring a warm welcome in the spring. Dive in confidently, knowing you’ve secured many more seasons of delightful warmth!
