Why a boiler needs a readiness check

A hot-water boiler is the quietest piece of equipment in the house, which is exactly why it gets forgotten. It sits through the dry months doing nothing, then is asked to run hard for months. Rubber seals dry out, the circulator can seize from sitting, and small leaks that were tolerable in spring become wet floors in November.

In Port Coquitlam, boiler homes are the exception rather than the rule among the forced-air bungalows and split-levels. That makes it more important, not less, to keep one in good order, because when it fails you want a clean maintenance record and a technician who already knows the system.

What you can safely do yourself

1. Look at the pressure gauge. Note the reading when the system is cool and again when it is hot, and write both down. A needle that has drifted far from where it normally sits, or one that keeps dropping, is something to report.
2. Walk around the boiler with a flashlight and look for drips, damp patches, white mineral crust or rust streaks on pipes, valves and the floor beneath.
3. Check that nothing is stored against the boiler or flue. Paint cans, laundry baskets and cardboard are common culprits in basement utility rooms.
4. Go outside and find the vent termination on the exterior wall. Clear leaves, cobwebs, grass clippings or garden clutter, and make sure nothing blocks it.
5. Turn the thermostat up and listen for the system to start. You are checking that it calls for heat and the circulator runs, not diagnosing it.
6. Feel the radiators or baseboards after the system has run for a while. Note any that stay cold, so you can tell the technician.

That is the full list for a homeowner. Do not open the casing, loosen fittings, touch gas valves, refill or drain the loop, or try to bleed air out of a system you do not understand. Those are jobs for a licensed person.

What the annual service covers

A genuine service is a working inspection, not a wipe-down. The technician examines the burner and heat exchanger, tests ignition and flame sensing, checks the safety controls, looks at the circulator and any zone valves, tests the pressure relief valve and expansion tank, and confirms that combustion air and venting are in order. Where the design allows, combustion is analysed rather than judged by eye.

We also look at the water itself. Dark, sludgy loop water tells a story about corrosion inside the pipes. Port Coquitlam is supplied with soft Metro Vancouver water, so scale is seldom the problem it can be elsewhere, but old systems can still carry years of iron oxide that wears on pumps and valves.

Ask for a written note of what was checked and found. Next year's technician, or you, will be glad of it.

Local conditions that affect boilers here

• Damp low-lying lots near the Pitt and Coquitlam rivers can mean damp basements, which accelerates corrosion on steel fittings and cabinets.
• Fall wind and rain storms can push debris against exterior vent terminations and, on occasion, bring down branches that disturb outdoor piping or vents.
• Outflow winds in a cold snap come down the Fraser valley and can chill exterior walls and crawl spaces, so insulation on any pipes running outside the heated envelope matters.
• Older homes closer to the downtown core may have original cast-iron radiators and mixed-age piping, where one weak joint can undo an otherwise healthy system.
• Homes with in-floor radiant need the boiler and the mixing controls working together; a boiler that runs hot or short cycles can be a controls issue rather than a failing boiler.

When to call rather than wait

Call a licensed gas fitter if you notice water around the boiler, a smell you cannot place, soot or scorch marks, unusual banging or gurgling, a pressure reading that keeps falling, or a boiler that starts and stops repeatedly. These are not problems that get better by being ignored.

If you have a carbon monoxide alarm, test it now and check its date, because fall is when sealed-up houses and busy heating equipment make it matter most. A boiler that is ready for winter is one you can forget about again from November to March.

Our technicians work under gas licence LGA0043870 and boiler licence LBP0046450. Service pricing is confirmed by the CANRO office after a short conversation, and repairs are quoted before the work begins.
