7 Warning Signs That Your Boiler Needs Repairs

Written by BooAdmin. Posted in Uncategorized

Whether your facility exists to manufacture new automotive parts or serve as a learning space for elementary school-age children, you must keep the building hospitable for your purposes. Both commercial and industrial properties rely on numerous mechanical systems to maintain proper interior conditions, including boilers.

When it works properly, your boiler heats your property. But when the boiler goes on the fritz, it can lead to discomfort, delays, or even unsafe conditions.

In this blog, we list seven warning signs that your boiler needs repairs so you can have issues addressed as early as possible.

1. Abnormal Smells

Boiler damage can lead to a number of leakages. If your boiler has a gas or oil leak, you may notice a metallic or eggy smell. Though carbon monoxide is odorless, gas suppliers add a sulfur smell to make gas leaks more detectable.

Gas leaks pose a serious health and safety hazard. When you notice any new smells around your boiler, have a professional inspect the unit immediately.

2. Advanced Age

Like any mechanical equipment, boilers will wear over time and need repairs. Most boilers can have new tubes installed and steel sections replaced as needed to restore them to original condition.

A good boiler can have a service life of up to 100 years with a few upgrades and repairs along the way. Always consult a Boiler repair shop before replacing a boiler.

3. Faulty Power

If your boiler fails to run after you turn it on, there may be a problem with the power supply. Check for any blown fuses that may need replacement.

If fuse troubleshooting doesn’t fix the issue, have a technician test the internal power supply system.

4. Heating Delays

When your unit functions properly, you should notice heat production soon after switching the boiler on. If it takes a long time for your unit to produce heat, you may have a circulation issue. You may also notice that your unit shuts off frequently and without warning to avoid overheating.

Sometimes this issue responds to a single repair, but it may also indicate the need for a newer, more efficient model.

5. Inadequate Heat

If your boiler produces heat, but your building never seems to reach the set temperature, it may indicate a heat delivery issue. These issues can stem from a number of sources, including buildup in the tank or short circuits in the thermostat.

Check your thermostat settings when you run your boiler. If your property doesn’t reach the desired temperature, call out for repairs.

6. Leaking Water

If you notice moisture or puddles around your unit, have a technician evaluate the unit as soon as possible. Standing or dripping water can cause serious property damage.

Additionally, leaky boilers use significantly more energy and have a much higher risk of bursting than their watertight counterparts.

7. Unusual Noises

One of the earliest detectable signs of boiler damage comes in the form of odd noises. You may hear clunking, thumping, whirring, or even whistling sounds.

These noises may indicate a broken heat pump, damaged heat exchanger, inefficient fan, or blocked system due to sediment buildup.


Pay attention to the way your boiler runs. Even small changes can indicate a mechanical issues, especially in older models. Taking care of these issues early protects you, your property, and the people who use your building from winter temperatures and boiler-related safety issues alike.
