What are the most common boiler failures and how to prevent them?

Central heating boilers are an inseparable element of many homes, guaranteeing warmth on cold days. However, like any device, boilers are also exposed to various failures. These are often problems that could be avoided with proper maintenance and regular inspection of the equipment. In this article, we will discuss the most common failures of heating boilers and suggest how to prevent them effectively in order to enjoy undisturbed warmth in your home.

Lack of hot water or heating

One of the most common problems is the lack of hot water and heating. There can be many reasons - from pump failure, through damage to the three-way valve, to problems with the burner. Regular servicing of the boiler and checking the condition of individual components can significantly reduce the risk of this type of failure.


Water leakage

Water leakage is another common failure. It is usually the result of damaged seals or corrosion of pipes. Regular inspection of the installation's tightness and replacement of damaged elements allows you to avoid this problem. It is also recommended to use the correct water quality in the system to minimize the risk of corrosion.


Fouling and deposits in boilers

Boilers are exposed to scaling and other impurities, which can lead to a decrease in the efficiency of the device. Regular cleaning and servicing of the boiler and the use of special anti-corrosion agents can help keep the boiler in good condition.


Ignition problems

Ignition problems are a common cause of gas boiler failures. They can be caused, for example, by damage to the ignition electrodes, lack of fuel or incorrect adjustment. It is important to regularly check the condition of the electrodes and, if necessary, replace them, and to ensure constant access to fuel.


Driver failure

The boiler controller is its "brain" - it is responsible for the proper functioning of the entire system. Failure of the controller may paralyze the operation of the boiler. Regular software updates and servicing of control devices are crucial to avoid these types of problems.


How to prevent failures?

The most important element of prophylaxis is the regular service of the boiler, carried out by a qualified specialist. Such a service should include, among others: inspection of the technical condition of the device, cleaning and replacement of worn parts. In addition, proper operation of the boiler, in accordance with the manufacturer's instructions, is fundamental. It is also worth paying attention to the quality of the fuel - low-quality fuel can lead to contamination and damage. It is also recommended to regularly check the condition of the installation and its tightness.
