Common Water Heater Problems in Calgary Homes
Whether you have a traditional tank water heater or a tankless on-demand system, these are the most frequent issues:
- No hot water: Can be caused by a failed heating element (electric), faulty thermostat, broken pilot light (gas), or ignition system failure.
- Not enough hot water: Sediment buildup in the tank, undersized unit, or failing heating elements.
- Water too hot or inconsistent: Thermostat miscalibration or faulty mixing valve.
- Leaks: Corroded tank, faulty T&P valve, or loose fittings.
- Strange noises (popping, banging): Sediment buildup at the bottom of the tank.
DIY Troubleshooting: What You Can Check First
- Before calling a Calgary water heater repair pro, try these safe checks:
- For gas water heaters:
- Confirm gas valve is On.
- Relight the pilot light (follow manufacturer instructions).
- For electric water heaters:
- Check the breaker in your electrical panel.
- Press the reset button (high-limit switch) on the unit.
- For both:
- Inspect for visible leaks around fittings and valves.
- Listen for unusual sounds (indicates sediment buildup).
Never attempt gas valve repairs, electrical wiring, or tank welding without a licensed technician—these are dangerous and code-regulated.

Before calling a pro, confirm the basics:
Reset the breaker (electric), relight the pilot light (gas), and verify thermostat settings.
