Hey hey, boiler buddies! 👋
It’s your girl Savvy Mavi here, and today we’re diving into something that’s equal parts grown-up responsibility and total peace-of-mind insurance: seasonal maintenance for your Weil-McLain hot water boiler.
You know how I feel about staying ahead of HVAC disasters. And trust me, there’s no sadder song than the gurgle of a boiler that’s been ignored all summer and suddenly refuses to heat up your home in January. 😩
So let’s talk checklists, tools, tips, and those “little things” that save you big 💰 and even bigger stress. Whether you’re a homeowner getting your feet wet or a DIYer who loves to get hands-on, this one’s for you.
🌱 Spring Shutdown Tips: Let It Rest the Right Way
Spring means heating season is winding down—but don’t just flip the switch and walk away. Your boiler deserves a little TLC before it hibernates.
Spring checklist:
-
Turn off the power and shut off the water supply to the boiler.
-
Flush the system to remove mineral deposits. This reduces corrosion risk and improves heat transfer.
-
Clean or replace filters in your zone valves or system piping if applicable.
-
Check for any signs of leaks—especially around the pressure relief valve and expansion tank.
-
Schedule a professional inspection if your boiler had any hiccups over the winter.

☀️ Summer Is for Inspection and Prep
Your boiler might be sleeping, but summer is actually the perfect time to schedule a professional inspection or take care of minor repairs.
Summer checklist:
-
Have a pro test the combustion and efficiency levels.
-
Inspect the circulator pump and electrical connections.
-
Replace aging gaskets or seals if there were signs of leakage.
-
Make sure your thermostat is calibrated and responsive (future you will thank you!).

🍁 Fall Startup: Your Boiler’s Back in Business
As the weather cools down, it’s time to wake that boiler up and get ready for action. Here's what you need to do before the first frost hits:
Fall checklist:
-
Turn the boiler power and water supply back on.
-
Bleed your radiators to remove any air pockets. This keeps your system balanced and efficient.
-
Check the expansion tank for proper pressure (usually around 12-15 PSI cold).
-
Test the thermostat to make sure it’s activating the boiler properly.
-
Lubricate circulator pump bearings if required.

❄️ Winter Vigilance: Keep Things Cozy
This is the time your boiler works the hardest, so a little routine attention goes a long way.
Winter checklist:
-
Listen for odd noises—banging, whistling, or rumbling could mean sediment buildup.
-
Monitor boiler pressure weekly. If it fluctuates dramatically, something's off.
-
Keep vents and flue pipes clear of snow or debris.
-
Don’t forget about your carbon monoxide detector—a critical safety layer for any boiler system.

🧠 Bonus: Log Your Maintenance
Savvy homeowners log each task with the date. You don’t need a fancy app—just a note on your phone or a dry-erase calendar in your utility room. This helps you spot patterns (like slow pressure drops) before they become real problems.
