What happens if a boiler overheats?

Why do boilers overheat? Typically, boilers overheat due to the failure of safety controls that maintain the gas and water supply, the temperature and the pressure. When boilers begin to overheat, the internal components of the boiler are put under immense stress and are likely to suffer from irreparable damage.Click to see full answer. Also, how do I know if my boiler is overheating? Watch out for overheating If you notice that your boiler’s temperature is going higher than the above settings, you have a major problem.

A build-up of sludge, limescale and other debris in the heating system is one of the most common causes of boiler overheating but this can be managed. For any properties with an older central heating system, the best way to prevent the unit from overheating is to simply have a new boiler installed.
