Common Causes of Commercial Boiler Breakdowns

Lack of regular maintenance

One common cause of commercial boiler breakdowns is the lack of regular maintenance. Without proper servicing and maintenance, boilers can become inefficient, leading to a higher risk of breakdowns. Regular maintenance allows for the identification and repair of minor issues before they escalate into major problems. It is important to have a maintenance schedule in place and ensure that it is followed consistently.

Wear and tear

Commercial boilers are subject to extensive use and can experience wear and tear over time. The constant heating and cooling of the system can cause components to deteriorate, leading to potential breakdowns. Regular inspections and parts replacement can help mitigate the risk of breakdowns due to wear and tear. It is important to be proactive in identifying and replacing worn-out components to avoid unexpected breakdowns.

Faulty components

Another common cause of commercial boiler breakdowns is faulty components. Components such as valves, thermostats, and pressure gauges can malfunction and cause the boiler to stop working properly. Identifying and replacing faulty components at the earliest signs of malfunction can prevent further damage and breakdowns. Regular inspections and testing can help in identifying any faulty components before they cause a complete breakdown.


Corrosion can significantly impact the performance of commercial boilers and lead to breakdowns. Over time, corrosion can weaken the boiler’s structure, cause leaks, and reduce efficiency. Regular inspections and preventive measures, such as treating the boiler with corrosion inhibitors, can help minimize the risk of breakdowns due to corrosion. Maintaining proper water chemistry and promptly addressing any signs of corrosion can extend the lifespan of the boiler and prevent unexpected breakdowns.

Deposits and scaling

The buildup of deposits and scaling in commercial boilers can impede their efficiency and eventually lead to breakdowns. Deposits such as sludge, sediment, and minerals can accumulate in the system and restrict water flow. Scaling, on the other hand, occurs when minerals in the water precipitate and form a hard layer on heat exchange surfaces. Regular cleaning and descaling of the boiler can help remove these deposits and scaling, preventing breakdowns caused by restricted water flow and reduced heat exchange efficiency.

Signs of a Commercial Boiler Breakdown

Strange noises

One of the first signs that your commercial boiler may be heading towards a breakdown is the presence of strange noises. These can include banging, whistling, or gurgling sounds coming from the boiler. Strange noises often indicate that there is a problem with the system, such as a faulty component or a buildup of debris. Ignoring these noises can lead to more severe issues and even complete system failure.

Decreased heating performance

Another sign of a potential commercial boiler breakdown is a decrease in heating performance. If you notice that the building is not getting as warm as it should or that it takes longer for the boiler to heat up the space, this could indicate a problem. Decreased heating performance can be caused by issues such as a malfunctioning thermostat, clogged pipes, or a failing heat exchanger. It is crucial to address these issues to prevent a complete breakdown.

Increase in energy bills

An unexplained increase in energy bills can be a sign that your commercial boiler is not functioning properly. When a boiler is not operating efficiently, it consumes more energy to achieve the desired heating output. If you notice a significant rise in your energy costs without any other identifiable cause, it may be a signal that your boiler is on the verge of a breakdown. Prompt attention and repair can help avoid further financial losses.

Leaking or dripping water

Water leaks or drips from a commercial boiler should never be ignored, as they are clear indicators of a problem. Leaks can be caused by various issues, such as a damaged pipe, faulty valve, or internal corrosion. If left unaddressed, leaks can lead to more severe damage, including property damage and even electrical hazards. It is essential to identify and repair the source of the leak to prevent a complete breakdown of the boiler.

Fluctuating pressure

Fluctuating pressure within the boiler system can be a sign of impending breakdown. A properly functioning boiler should maintain a stable pressure level. Fluctuations in pressure can indicate issues such as a faulty pressure relief valve, water leaks, or obstructions within the system. It is important to investigate and resolve the underlying cause of the pressure fluctuations to prevent any further damage and potential breakdowns.

Preventive Measures to Avoid Commercial Boiler Breakdowns

Regular servicing and maintenance

Regular servicing and maintenance are essential for preventing commercial boiler breakdowns. By scheduling routine inspections and maintenance, you can identify potential issues before they escalate and cause a complete breakdown. During these maintenance visits, a qualified technician can clean and inspect the boiler, check for worn-out components, and ensure that the system is operating efficiently. Regular servicing and maintenance can prolong the lifespan of the boiler and minimize the risk of breakdowns.

Monitoring and addressing any strange noises

Monitoring your commercial boiler for any strange noises is crucial in preventing breakdowns. If you notice any banging, hissing, or rumbling sounds coming from the boiler, it is important to have it inspected by a professional. Strange noises often indicate that there is an underlying issue that needs immediate attention. By addressing these noises promptly, you can prevent further damage and potential breakdowns.

Checking and maintaining proper pressure levels

Regularly checking and maintaining the proper pressure levels within your commercial boiler is essential for its optimal performance. Low or high pressure can both lead to breakdowns and system inefficiency. Monitoring the pressure gauge and ensuring it falls within the recommended range can help prevent potential breakdowns. Additionally, addressing any pressure fluctuations promptly can help identify and resolve underlying issues.

Inspecting and cleaning the system regularly

Regularly inspecting and cleaning your commercial boiler system is essential for preventing breakdowns. Inspections can help identify any signs of wear and tear, corrosion, or deposits that can lead to system failure. Cleaning the boiler system, including pipes, coils, and heat exchangers, removes any accumulated debris that could impede performance and efficiency. By maintaining a clean and well-maintained system, you can minimize the risk of breakdowns.

Treating and preventing corrosion

Implementing corrosion prevention measures is crucial for avoiding commercial boiler breakdowns. Corrosion can significantly impact the performance and lifespan of a boiler. Treating the system with corrosion inhibitors can help prevent the formation of rust and corrosion, extending the life of the boiler and reducing the risk of breakdowns. Regular water testing and treatment can help maintain proper water chemistry, further minimizing the potential for corrosion-related breakdowns.

What to Do When Your Commercial Boiler Breaks Down

Contact a professional boiler repair company
