A common but critical problem that boiler owners may face is excessively high pressure. This condition can be dangerous, decrease system efficiency, and potentially cause costly damage.

In this article, we will look at why boiler pressure can get too high and how you can take action to lower it safely and effectively.

What are the causes of excessive pressure in the boiler?

Several situations can lead to too high pressure in the boiler:

• Faulty safety valves: if they fail to work properly, they might not release pressure as required, leading to a dangerous increase.
• Water supply problems: a malfunction in the system that regulates the water inlet can cause an uncontrolled pressure increase.
• Incorrect settings: an incorrectly set pressure regulator can contribute to the pressure increase.

 

How to lower boiler pressure

When the pressure in the boiler system exceeds the normal level of 1.5/2 bar (depending on the model), it is essential to take immediate steps to bring it back to a safe value. Here are some effective methods:

1. Checking and adjusting the safety valve: ensure the safety valve is functioning properly.This should open automatically to release water and reduce pressure when it becomes too high. If the valve is defective or blocked, it may need adjustment or replacement.
2. Venting radiators: air trapped in radiators can cause an increase in pressure. Venting the radiators can help normalize the situation. Slowly open the vent valve and let the air escape until water starts to come out. Sometimes it may also be necessary to allow some water to escape.
3. Adjust the pressure regulator settings: make sure that the pressure regulator is set correctly for your system. Too high a setting can contribute to increased pressure in the system.

These operations can be carried out independently by individuals with a good knowledge of the system and its operation: if you do not feel confident, hire a qualified professional to carry out the work without risk.

How to prevent overpressure problems

To avoid problems related to excessively high pressure, it is essential to conduct regular maintenance and frequently check the boiler pressure. Here are some tips:

• Regular check: check the boiler pressure periodically, especially during the winter months when usage is more intensive.
• Professional maintenance: ensure that a qualified technician examines and maintains your boiler system regularly.
• Prompt response: intervene quickly if you notice high pressure to avoid greater and potentially costly damage.

By implementing these tips, you can keep your boiler system operating efficiently and safely while optimizing comfort and energy savings in your home.
