After a major storm, a boiler could be at risk for damage that requires repair or replacement parts. Whether it's due to flooding, loss of electricity, or physical impact, the effects of extreme weather can adversely impact heating operations. Keeping an eye on the signs of damage can save you from costly repairs or even full boiler replacements. Here are the top 7 indicators a boiler might need attention.
1. Water Damage or Flooding
Flooding is one of the most common reasons for boiler malfunction. If a boiler has been submerged in water, even partially, it’s likely that essential parts like controls, burners, or electrical components have been compromised. Water can corrode parts over time or immediately short out electrical systems. If a boiler shows signs of water exposure—like rusting, leakage, or malfunctioning electronics—it’s essential to have it inspected and replace any damaged parts, such as burner tubes or control panels.
2. Loss of Power or Electrical Damage
Storms often bring power outages, and a loss of electricity can lead to damage in boiler systems. Boilers rely on electricity to control their operations, and if they’re hit by a power surge from a lightning strike or extended outage, key parts like the ignition system or controls may fail. If a boiler isn’t firing up after the power is restored, you may need to replace the controls or other electrical components that were damaged.
3. Physical Impact or Wind Damage
Strong winds and flying debris can physically damage a boiler’s exterior or vital internal components. If a boiler was located in an area that was exposed to falling objects, like tree branches, or if the building itself suffered damage, it’s worth checking the boiler for dents, cracks, or other visible issues. Look for signs like misaligned sections or bent parts. If you spot physical damage, parts such as boiler sections, door clamps, or even gaskets may need to be replaced to restore proper function.
4. Unusual Noises
Pay close attention to how a boiler sounds. Strange noises such as banging, clanging, or whistling often indicate underlying issues caused by storm damage. For example, a damaged burner tube or a malfunctioning pump might create these sounds. Uncommon noises could mean that water has gotten into places it shouldn’t, or that physical damage has shifted parts out of alignment. Promptly replacing faulty parts like burner tubes or pumps can prevent further damage.
5. Inconsistent Heating or No Heat
One of the most telling signs of damage is inconsistent heating or a complete lack of heat. If you find that a boiler is struggling to maintain temperature, it could indicate damage to the combustion chamber or power burners. Flooding or electrical issues could also cause the thermostat and controls to malfunction, leading to erratic heating behavior. In this case, you may need to replace specific parts like the combustion chamber products or gauge glass to restore reliable heating.
6. Leaks
Leaks are a significant red flag that a boiler has been damaged. Water can corrode gaskets and seals, leading to leaks that can cause further damage if left unchecked. Look out for puddles forming around the base of the boiler or dripping from parts like the coil gaskets or door clamps. Replacing these damaged seals immediately can help you avoid more severe problems down the line.
7. Increased Energy Bills
If your energy bills spike, it’s possible a boiler isn’t working as efficiently due to storm or flood-related damage. Parts like the burner tubes or power burners may have been compromised, causing the boiler to work harder than it should to heat your space. Replacing these damaged parts can help restore efficiency and lower your energy costs.
