When temperatures start to drop and pool season winds down, it's essential to show your pool heat pump some love before winter fully sets in. A little prep work can save you from costly repairs later. Here's a step-by-step guide on winterizing your pool heat pump and keeping it in top shape for next season.
Why Winterizing Matters
Your pool heat pump isn't a fan of freezing temperatures. Water left inside the unit can expand when it freezes, potentially cracking internal components like the heat exchanger or piping. Moisture buildup can also lead to corrosion or electrical damage. Proper winterization helps prevent these issues and extends the life of your unit.
Step-by-Step Guide to Winterizing Your Pool Heat Pump
1. Turn Off the Power
Safety first! Locate the circuit breaker that controls your pool heat pump and switch it off. This prevents the unit from turning on accidentally while you're working on it.
2. Shut Off the Water Supply
Turn off the pool pump and close any valves leading to or from the unit to prevent water from circulating through the heat pump.
3. Drain the Heat Pump
Remove all water from the system:
-
Disconnect the inlet and outlet unions.
-
Let any remaining water drain out completely.
-
If your unit has a drain plug, remove it to allow complete drainage.
Pro Tip: Tilting the unit slightly can help clear out stubborn water pockets.
4. Clean the Exterior
Wipe down the outside of your heat pump to remove debris, leaves, or dirt. This prevents grime from baking onto the surface when temperatures fluctuate.
5. Cover It Up (Carefully)
Use a breathable, weather-resistant cover designed for pool equipment. Avoid completely sealing the unit with plastic, which can trap moisture and cause internal damage.
6. Inspect and Store Accessories
If your heat pump includes detachable parts, inspect them for wear and store them in a dry, sheltered area.
Bonus Tip: Keep an Eye on It
Check your covered unit occasionally throughout the winter. Make sure the cover stays in place and that no critters have tried to make it their winter home.
When to Reopen
Once spring rolls around and temperatures stay consistently above freezing, you can reverse the process:
-
Reconnect the plumbing.
-
Check for leaks.
-
Restore power.
-
Test the unit to ensure it's working correctly.
