Signs your domestic boiler is overheating

The boiler is an important part of daily life for most UK households, providing heating and hot water on demand. However, boilers can experience a number of problems and issues, including overheating. This can lead to a full boiler breakdown. So what are the signs that your domestic boiler is overheating? And what should you do? 

What are the most common signs that your domestic boiler is overheating?

There are a number of signs to look out for that could indicate that your domestic boiler is overheating. These include:

  • Abnormal noises: If you notice strange noises coming from your boiler, such as banging, hissing, or gurgling sounds, it could be a sign of overheating. These noises may indicate that the water inside the boiler is boiling excessively or that there is a buildup of pressure.
  • Increased boiler temperature: Check the temperature gauge on your boiler. If it is constantly rising above the recommended or normal operating range, it suggests that the boiler is overheating. Typical boiler temperature settings are between 60 to 80 degrees Celsius, depending on the type of boiler and its specifications.
  • System shutdowns: An overheating boiler may automatically shut down to prevent further damage. If you experience frequent boiler shutdowns or the system keeps tripping, it could be an indication of overheating.
  • Hot or excessive heat emanating from the boiler: If you notice that the boiler is excessively hot to the touch or that the surrounding area feels unusually warm, it may be a sign of overheating. This can be an obvious physical indicator, and caution should be exercised to avoid burns or other accidents.
  • Unusual smells: A distinct smell of burning or overheating components, such as plastic or electrical odors, can signify an overheating boiler. If you detect any unusual smells coming from the boiler or the surrounding area, it is essential to address the issue promptly.

Should you suspect that your domestic boiler is overheating, it is crucial to take immediate action. Firstly, turn off the boiler and allow it to cool down before attempting any further assessment.
