By the time Chicago gets its first cold snap for the season, your commercial boiler should have already had a full startup check and be ready to go. Waiting until the building needs steady heat makes every small problem harder to deal with and can compromise your employees’ health and productivity. Our team at Althoff Industries, Inc. helps Chicago facility managers catch boiler issues early, plan repairs around operations, and avoid unnecessary downtime when temperatures drop.
Commercial Boiler Combustion Testing Before Winter
Start your boiler checkup with a combustion test to make sure it’s not firing up and running poorly. Our technicians check the ignition, burner operation, draft, venting, combustion readings, and safety controls before the system is under a full heating load. Checking the combustion is crucial in facilities with large exhaust systems or changing production demands. Exhaust fans can affect pressure inside your building and change how combustion air moves. Testing the boiler while the facility is operating normally can uncover problems that don’t always show up during a quick startup.
Boiler Pump and Circulation Problems
Watch how well heated water moves through the system. A failing pump doesn’t necessarily stop working all at once. You may notice cold areas, slow warm-up, unusual noise, vibration, or a pump that runs hot before it fails. Check the seals, bearings, valves, strainers, and pump operation. If you have access to boiler records, compare current amperage, pressure, or flow with previous readings. That can help you spot a pump that’s working harder than it should before it turns into a no-heat call.
Commercial Boiler Controls and Safety Devices
Boiler controls also need more than a thermostat check. They need tests for low-water cutoffs and issues with operating limits, sensors, thermostats, safeties, and building automation commands. We also recommend reviewing schedules and setpoints. If occupancy, tenant hours, or production schedules have changed since last winter, the old settings might not make sense for this season.
Expansion Tank and Boiler Pressure Problems
Expansion tank problems are often easy to miss when the boiler isn’t being used and is cold. But if the pressure rises sharply during a heating cycle or fluctuates more than usual, the tank could be waterlogged, improperly charged, or isolated from the system. Checking the pressure when the boiler is heating up can help catch issues before they lead to a service call.
Boiler Piping and Water Treatment Problems
Take a look around your boiler room for leaks, corrosion, damaged insulation, stained fittings, or scale buildup. It’s also a good idea to review your water treatment records since poor water chemistry can affect heat transfer and wear down piping over time. The type of facility you work in also matters for keeping your boiler running. Simple repairs can turn into more complicated jobs if you work in a food manufacturing plant with strict sanitation rules, restricted areas, or production schedules to work around.
