Boiler Loosing Pressure

If you’re noticing that your boiler is losing pressure, it can be a worrying issue to deal with. Not only can it cause your heating to be less effective, but it could also result in damage to your boiler. Fortunately, there are steps you can take to address the issue.

Why is your boiler loosing pressure

Firstly, it’s important to understand why your boiler might be losing pressure. There are several reasons this can occur.  One common cause is a leak in the system, which could be caused by a faulty component, such as a valve or a seal. Another possibility is that there is air trapped in the system, which can cause the pressure to drop.

Check if there is a leak

One of the first things you can do to address the issue is to check for visible leaks in the system. This could include looking for any drips or puddles of water around the boiler or radiators. If you do find a leak, you should contact a professional heating engineer as soon as possible to repair it.

Check if there is trapped air in radiators

If you can’t see any visible leaks, the issue could be caused by trapped air in the system. This can be addressed by bleeding the radiators. To do this, you’ll need to turn off the heating and allow the radiators to cool down. Once they have cooled, use a radiator key to open the valve at the top of the radiator and release any trapped air. You’ll know the process is complete when water starts to flow out of the valve instead of air. Once you’ve bled all of the radiators in your home, you should be able to check the boiler pressure again and see if it has improved.

Call a heating engineer to check for faulty components

If bleeding the radiators doesn’t solve the problem, there could be an issue with a faulty component in the system. In this case, it’s best to call in a professional heating engineer to diagnose the problem and repair or replace any damaged parts.

One possible reason for a boiler losing pressure is a damaged pressure relief valve. This valve is responsible for regulating the pressure inside the boiler, preventing it from becoming too high. If the valve is damaged, it may not be able to function properly, causing pressure to drop.

Another possible cause is a damaged expansion vessel. The expansion vessel is a vital component of your heating system, and is responsible for accommodating the expansion and contraction of water as it heats and cools. If the vessel is damaged, it may not be able to perform its function, causing pressure loss.

To address these issues, it’s important to call in a professional heating engineer who can diagnose and repair the problem. They may need to replace the pressure relief valve or expansion vessel to restore proper pressure levels.

It’s also possible that the issue is due to a blocked pressure gauge or a faulty pressure sensor. In this case, the engineer can clean or replace the gauge or sensor to restore accurate pressure readings.

To prevent pressure loss from occurring in the first place, it’s important to perform regular maintenance on your boiler and heating system. This includes scheduling annual servicing appointments with a qualified engineer to check for any potential issues and make any necessary repairs. It’s also a good idea to keep an eye on your boiler’s pressure gauge and take note of any fluctuations.

If you do notice a drop in pressure, it’s important to address the issue promptly to prevent any further damage. In some cases, low pressure can cause your boiler to shut down, which can lead to a loss of heating and hot water.

In conclusion, if you’re experiencing pressure loss in your boiler, it’s important to take action to address the issue. Call in a professional heating engineer to diagnose and repair the problem, and schedule regular maintenance appointments to prevent the issue from occurring in the first place.
