Boiler Pressure Too High? Here's What to Do

If your boiler pressure is too high, it can be a serious safety hazard. It can also cause damage to your boiler and heating system and increase your energy bills. We will discuss what to do if you notice that your boiler pressure is too high and we will also provide some tips for preventing this from happening in the future. Keep reading to learn more.

What Causes High Boiler Pressure

There are a few different things that can cause your boiler pressure to become too high. One of the most common causes is simply that the boiler has been turned on and is heating up for the first time in a while. This can cause the water in the system to expand, which raises the pressure.

Another common cause is a leak in the system. This can be caused by many things, including a cracked heat exchanger or a loose pipe fitting. Whatever the cause, it's important to fix any issues as soon as possible to avoid further damage to your system.

How do you know if your boiler pressure is too high?

If you have an analogue boiler pressure gauge, it should be easy to tell if your boiler pressure is too high. The needle should be in the green section of the gauge, which is between one and two bars. If it's any higher than that, then your boiler pressure is too high.

If you have a digital boiler pressure gauge, you can usually find the current reading on the display. Most boilers should be set to around one bar, so anything above that is too high.

How To Lower Boiler Pressure

If you think that your boiler pressure is too high, the first thing you should do is check the pressure gauge. If it's in the red zone, or if the needle is above two bars, then you need to take action. First, check to see if there are any leaks in the system. If there are, turn off your boiler and call a qualified engineer to come and fix the problem.

If there are no leaks, then you can try bleeding the radiator to release some of the pressure. This is a fairly simple process that you can do yourself. Just turn off your boiler and start with the radiator furthest away from the boiler. Find the bleed valve on the radiator and once you've found it, turn it anti-clockwise to release some of the pressure. You should see the water start to drip out of the valve. Keep bleeding until the water runs clear and then close the valve again. Repeat this process on all of your radiators until the pressure has dropped to the correct level.

If your boiler pressure keeps rising, or if you can't seem to get it down to a safe level, it's time to call a professional. A qualified heating engineer will be able to safely carry out any repairs that are needed and they can also give you advice on how to prevent this from happening in the future.

Tips For Preventing High Boiler Pressure

There are a few things you can do to help prevent your boiler pressure from becoming too high. First, make sure that you check the pressure regularly and top up the water if it starts to get low. You should also bleed your radiators on a regular basis to release any built-up pressure. If you have an annual boiler service, make sure that your engineer checks the boiler pressure and carries out any necessary repairs.

Following these tips will help ensure that your boiler stays at a safe pressure and continues to work efficiently. However, if you do experience problems with high boiler pressure, don't hesitate to contact our team of experts at Corvee Services for help.
