Generally, new-age boilers have a safety feature that recognises overheating and shuts down automatically. Whatever it is, you need to know the culprits behind boiler overheating and, more importantly, how to fix it.

Top Reasons for Boiler Overheating

Overheating of boilers arises due to the following reasons:


System blockage

If there is a blockage in the system, you will come across unusual sounds from the boiler. Usually, physical and air blockages are the two common types of system blockages.

Decreased water levels

If there is a leakage in your boiler, it will result in low water levels. Sometimes, decreased water levels also arise due to the sudden shutdown of the boiler.

Broken thermostat

The thermostat in the boiler regulates the water temperature. However, this thermostat may break over time, thereby increasing the water temperature.

Defective pump

A boiler system has a water pump that circulates the water. If the pump is damaged, boiler overheating will be a common phenomenon.

Tips for Fixing an Overheating Boiler

Evaluate the water level

It is the initial sign of boiler overheating. If the water level is below or above 1 and 2 bars, you should know there is a problem with the system.

Clean the pipes

Stuck pipes can occur anytime. In such cases, a power flush is the only solution. This cleansing approach will eliminate limescale and rust from your boiler system.
