As previously mentioned, if your boiler is consistently running at a higher pressure it could cause a system failure or damage to your home. A good indicator as to whether your boiler pressure is too high is if you can see water leaking or dripping from the pressure relief valve, usually located on outside wall where the unit has been installed.

29-04-2020· High boiler pressure isn’t dangerous, even if it’s showing as three bar on the pressure gauge. In most cases, the boiler will turn itself off if the pressure goes about a certain level and a working PRV should successfully control the pressure, preventing it from getting too high.

To simplify what pressure means it is basically the balance of water and air inside the boiler system this includes the pipes as well. A balanced pressure is necessary if you want to heat the water that travels around your home. If the pressure is too low or too high this won’t be possible and can cause a myriad of other problems.

However, as boilers contain pressure relief valves, you don’t have to concern yourself too much – if the boiler is not making any noises and seems to be working properly, then it will be safe for the time-being, and the pressure relief valve will prevent the boiler from overpressurising.

In the vast majority of cases – no. Most boilers will simply shut down via a safety device called a PRV (P ressure R elease V alve), or break down when pressure is too high, for too long. The worst case scenario for most boilers suffering from high pressure will be a broken boiler and a soaked carpet.

What happens if theboiler pressure is too highis that the system comes under excess strain and is at risk of breaking down. Boiler pressure is used to pump the hot water around your home, into your radiators and to your taps and showers.

The green area that you see in the image above is the standard operating pressure – which usually covers between 1 and 1.5. The red area tells you when the pressure is too high, but watch out for it falling below 1 as well. In many modern boilers, if the pressure drops below around 0.5, there is a low pressure cut-off switch that can save you
