02 — SYMPTOMS

Common Boiler Problems in Older Ottawa Homes

Most calls we get are about boilers 10 to 15 years old, and most start in the first cold week of the season.

Heat & Hot Water
No heat at all Call now
Likely cause

Ignition failure, a worn circulator pump or a control fault in an ageing boiler.

Safe to check yourself

Check the thermostat setting and the boiler's power switch. Don't remove the cover or repeatedly reset it.

Combi gives heat but no hot water Book soon
Likely cause

A sticking diverter valve, faulty flow sensor or deposits in the plate heat exchanger.

Safe to check yourself

Check whether the display shows an error code and note whether the problem affects every tap.

House won't reach the set temperature Book soon
Likely cause

Reduced boiler output, an ageing pump or heat exchanger deposits. Cold snaps can make the problem more noticeable.

Safe to check yourself

Confirm the thermostat schedule and record the temperature shown on the boiler display.

Water & Pressure
Pressure keeps dropping Book soon
Likely cause

An expansion tank problem, pressure relief valve seepage or water escaping from the system.

Safe to check yourself

Note the pressure when the boiler is cool. Don't keep adding water to compensate for recurring pressure loss.

Pressure too high / relief valve dripping Book soon
Likely cause

An expansion tank that has lost its air charge, a faulty filling valve or a pressure relief valve that needs attention.

Safe to check yourself

Read the pressure gauge and note whether dripping happens only while the boiler heats. Don't block the discharge pipe.

Water under the boiler Call now
Likely cause

A leaking internal connection, pump seal, valve or condensate assembly.

Safe to check yourself

Keep clear of the water and electrical parts. If leaking is active, call for guidance rather than opening the boiler.

Ignition & Controls
Won't ignite or locks out Call now
Likely cause

A worn ignition electrode, flame sensor, gas valve or another boiler safety-control fault.

Safe to check yourself

Record any error code. Don't repeatedly reset a boiler that locks out or attempt to light it manually.

Error code on the display Book soon
Likely cause

The code may indicate ignition, pressure, fan, sensor or condensate trouble. Its meaning depends on the model.

Safe to check yourself

Photograph the display and note the boiler brand and model. A boiler fix near me visit is easier to prepare when we have the exact code.

Turns on and off every few minutes Can wait
Likely cause

Short cycling may come from control settings, temperature sensors or restricted heat transfer.

Safe to check yourself

Note how often the boiler starts and stops. Schedule an inspection if it continues, even when the house remains warm.

Winter-Specific
Frozen condensate line Call now
Likely cause

Ice blocks the condensate drain on a condensing boiler, causing a safety shutdown during severe frost.

Safe to check yourself

Look for an accessible outdoor condensate pipe from a safe position. Don't use flames, boiling water or tools to break ice.

Boiler stops during a cold snap Call now
Likely cause

Blocked venting, a frozen condensate line or an ageing component failing under sustained winter demand.

Safe to check yourself

From a safe location, check whether snow is obstructing the outdoor vent. Record the error code and call for assistance.

SOUND GUIDE

What's That Noise?

An older boiler can make very different sounds. Here's what they may mean before you describe them to a technician.

Banging or Kettling

Deposits inside the heat exchanger or poor circulation can cause rumbling or sharp knocking.

Book soon

Gurgling

Air moving through the boiler or unstable water pressure may produce bubbling sounds.

Can wait

Whistling or Hissing

A restriction, escaping pressure or an internal valve problem can create a high-pitched sound. A suspected gas leak needs immediate evacuation.

Call now

Clicking but No Flame

The ignition system may be attempting to start but failing to establish or detect a flame.

Call now
Safety first

Smell gas or hear a CO alarm? Leave the house and call 911 first.
