What is high boiler pressure?

For a boiler to function correctly, the balance of air and water in the system needs to be just right. High boiler pressure is a pressure reading that is around the 3-4 mark on the pressure gauge. This is far above the acceptable boiler pressure level of 1-1.5, and it can cause some significant issues.

What are the problems cause by high boiler pressure?

High boiler pressure can cause a range of problems, including:

  • Leaks- as the pressure builds too high, the water can leak from anywhere inside the boiler, or from the wider central heating system. This can cause expensive damage to your property.
  • Boiler breakdown- a lot of boilers have a safety function which forces the boiler to shit down with the pressure gets too high. This means that you wont be able to use your boiler at all, until it is fixed by a professional. And boilers without this function, are likely to breakdown as well.

What are the most common causes of high boiler pressure?

So what exactly causes high boiler pressure? Well, this is caused by a range of factors including:

  • Too much water in the system- if your boiler has allowed too much water into the system, this will increase the pressure. You will need to reduce this water level.
  • Faulty boiler parts- the boiler pressure release valve or the filling loop can both break down. Problems with either of these can result in too much water or air increasing the boiler pressure.
