Boiler may be a considerable annoyance, particularly during the colder months. Understanding the most prevalent causes of boiler failure can help you discover problems early and save costly repairs. Here are the five most pervasive reasons for boiler problems and what you can do about them.
1. Boiler: Lack of Maintenance
A lack of regular maintenance is one of the most common causes of boiler failure. Like other mechanical systems, boilers require consistent inspections and servicing to function efficiently. Over time, components such as the heat exchanger, pumps, and valves can become clogged with dirt or wear out, leading to operational issues. For instance, without proper upkeep, small problems may go unnoticed until they escalate into costly repairs. Therefore, it is essential to schedule annual servicing with a licensed plumber. Regular maintenance not only helps detect potential issues early but also prevents unexpected breakdowns and further complications.
2. Low Pressure of the Boiler
When you notice low pressure in your home, your boiler has broken. Various issues, including leaks in the system or a faulty pressure relief valve, can cause low pressure.
Regularly checking your boiler’s pressure sensor is crucial for maintaining optimal performance. If you notice a drop in pressure, you might need to replenish the system with water or inspect it for potential leaks. However, if you’re unsure how to handle this safely, it’s always wise to consult a specialist for expert guidance.
3. Boiler Thermostat
A broken thermostat may cause your boiler to stop working or operate inefficiently. If the thermostat does not read the temperature correctly or has become unresponsive, it may fail to turn on or off the boiler as necessary.
Ensure your thermostat is in a position that accurately reflects the room temperature and is not obscured by furniture or other objects. If you suspect a problem with the thermostat, it may need to be adjusted or replaced.
4. The pilot light or ignition system
A common issue with older boilers fitted with a pilot light is failure. Modern boilers with electronic ignition systems may need help preventing the system from igniting the burner. A dirty or damaged flame sensor, a defective igniter, or issues with the gas supply can all create ignition system problems.
If your boiler has a pilot light, examine and clean it regularly. For electronic ignition systems, ensure that the gas supply is consistent and have the system checked if you experience ignition difficulties.
5. Blocked or Leaking Pipes
Blocked or leaky pipes might cause severe damage to your boiler. Blockages can result in pressure buildup and overheating, whilst leaks can degrade system performance and cause damage over time. Both problems can be caused by corrosion, ice, or other impediments.
Inspect visible pipes regularly for evidence of leaks or clogs. In cold weather, make sure your pipes are insulated to avoid freezing. If you suspect a clog or leak, contact a professional immediately so the condition does not worsen.
