Nothing halts comfort in your home or business faster than a boiler that suddenly stops working—especially in the middle of an Edmonton winter. When your heat disappears and the water turns cold, panic sets in. But before you call in the professionals (yes, Flawless Flows Mechanical is ready to help 24/7), there are a few essential steps you can take to diagnose the issue, possibly resolve it yourself, and ensure a smoother, faster fix if a pro visit is needed.
At Flawless Flows Mechanical, we believe in empowering our customers with knowledge. So whether you’re in Edmonton, Sherwood Park, Beaumont, Spruce Grove, or Stony Plain, here’s your go-to guide for handling boiler trouble with confidence.
First Things First: Safety Check
Before you touch anything, always ensure the area is safe.
- Smell gas? Do not attempt to troubleshoot. Evacuate and call your utility provider immediately.
- Hear strange clanking or notice water leakage? Turn off the power and water supply to the boiler and proceed with caution.
- Electric boiler? Make sure you’re not handling anything with wet hands or standing in water.
If anything feels dangerous or beyond your comfort zone, call us right away at 780-245-3569. Your safety comes first.
Step-by-Step: What to Check Before You Call
1. Check the Thermostat
It might sound obvious, but it happens all the time: a thermostat gets bumped or switched off accidentally.
✅ Make sure:
- It’s turned on.
- The temperature is set above current room temperature.
- It’s set to “heat” mode (not just “fan” or “cool”).
- The batteries (if wireless) are working.
Tip: A dead thermostat means your boiler doesn’t even know it’s needed.
2. Inspect the Power Supply
Boilers need electricity, even gas ones. Check if:
- The boiler’s power switch is on.
- Breakers haven’t tripped in the electrical panel.
- There are any visible signs of power loss (no lights or sounds).
If your system has an emergency shut-off switch (usually red and near the boiler), make sure it’s turned on.
3. Check the Pressure Gauge
Most boilers need water pressure between 1 and 2 bar. If it drops too low, the system may shut down to protect itself.
👀 Look for:
- A pressure gauge on the front or underside of the boiler.
- If the pressure is below 1 bar, that could be your culprit.
Some systems allow you to repressurize manually via a filling loop. But if you’re unsure how, don’t guess. Call the pros at Flawless Flows, and we’ll walk you through it or visit your home directly.
4. Reset the Boiler
Many modern boilers come with a reset button. You may need to hold it for 5–10 seconds.
💡Only try this once. If the boiler doesn’t come back to life—or resets but fails again, there’s a deeper issue that needs professional care.
5. Bleed Radiators (If You Hear Gurgling)
If your boiler is working but your radiators are cold or only partially warm, trapped air could be the issue.
🛠 You can bleed your radiators using a radiator key:
- Turn off the heat.
- Use the key to open the valve (top of radiator).
- Wait for air to hiss out, then close when water starts dripping.
This helps distribute heat more evenly and reduces strain on the boiler.
6. Look for Error Codes
If your boiler has a digital display, it may be flashing an error or fault code.
Take note of it before resetting or calling us. It gives our team at Flawless Flows a head start in diagnosing the issue and bringing the right parts.
Is It Frozen? Special Warning for Alberta Winters
In frigid Edmonton-area temps, frozen condensate pipes are a common cause of boiler failure.
Look for:
- A plastic pipe running from your boiler to outside.
- Blockage or frost on the pipe.
Try:
- Pouring warm (not boiling) water over the pipe.
- Resetting the boiler once thawed.

Common Boiler Problems That Need a Pro
If the above steps don’t restore heat, here are signs that it’s time to stop troubleshooting and call in Flawless Flows:
- Repeated resets or inconsistent power
- Leaking from the boiler
- Noisy operation – banging, clanking, whistling
- Low pressure that won’t stay up
- Pilot light issues or irregular flame
- Error codes you can’t resolve
Attempting DIY fixes beyond the basics can be dangerous, and may void your manufacturer warranty.
