Low boiler pressure symptoms

| 24 views

Whether it’s tucked away in the corner of the room or nestled inside a cupboard, the boiler is one household appliance we take for granted. In particular, it delivers an essential service, providing us with hot water for washing dishes and taking relaxing baths. At the same time, we tend only to pay attention to our boilers when something goes wrong. However, one issue affecting a combination boiler is the start of low boiler pressure symptoms. You can learn more about similar topics if you check out the Boiler Solutions video blogs on our site. Also, learn more about important elements of boiler-related services, such as the hot water cylinder service in London.

Consequently, your boiler must contain a minimum water level to operate safely. This will usually be between one or two bars on your system. So, when boiler pressure is low, it results in a low amount of water circulating in the system. As a result, your boiler and central heating will not work correctly. Hence, it would pave the way for a waste of energy as it attempts to heat your home with low pressure. So, once you know the common water pressure boiler symptoms, this issue is relatively easy to diagnose. Also, refer to details on our homepage, on the topic of boiler repair London.

What are the causes?

Low water pressure often occurs when your boiler has been idle for a long time. As an example, this would occur during the summer where we would be using less hot water. So, if your boiler pressure drops more than once or twice a year, it may be due to two leading causes of low boiler pressure: water leaks and bleeding radiators. Therefore, leaks are bound to happen from your pipes, boiler or your radiators. In this case, you will likely notice a leak if you see wet patches around these components on your floor.

On the other hand, you may also have a leak inside the boiler or underneath the floor, but you will be unable to see this. So, call an engineer to investigate if you can see a leak or suspect that you have on. Bleeding radiators can also lower the pressure in your boiler. Subsequently, if you have recently bled your radiators, you may need to increase your boiler pressure. At the same time, if you’re wondering about how often should you bleed radiators? then our site has a video blog on this topic.

How to increase boiler pressure

If your system shows the above boiler low-pressure symptoms or a low-pressure error code, the pressure likely needs to be increased. It is a simple process which you can do yourself by referring to the boiler’s manufacturer’s manual. Otherwise, you can also get advice from your energy provider. In this case, if you are unsure about how to increase the boiler pressure, you can call an engineer and leave it to them. Ultimately, you can begin to enjoy your hot water once more. In essence, you can also be proud of the knowledge that you can identify low boiler pressure and solve the issue.

Symptoms of low boiler pressure

If the pressure of the hot water inside your boiler is low, you may notice the following symptoms:

  • You have no heating or hot water
  • Your radiators are not warming up properly
  • The dial on your pressure gauge has fallen

Similarly, you might also encounter an error code on the front of your boiler. Consult the manufacturer’s guide to check if this error code correlates with low boiler pressure.
