Boiler Pressure Too High? 4 Fixes to Reduce Boiler Pressure

#3 Boiler Pressure Rises (MORE Than 0.3 Bar When Heating/Hot Water Is On) As weve mentioned a rise in pressure of under 0.3 bar is normal for boilers. But if you notice that the higher the pressure goes the quicker it increases (and its rising by well above 0.5 bar) there is likely to be a pressure release issue.

External Pressure Pressure Vessel Engineering

Jul 05 2012 · The inflation pressure can be as high as 800psi. This inflation pressure is higher than the required burst pressure and is far in excess of any allowed external pressure for the vessel. This only works because the pressure inside a dimple jacket is not an external pressure. The dimple jacket is a form of stayed jacket that can be any shape.

How to increase boiler pressure | Viessmann

On most boilers this will be shown as a green zone on the pressure gauge. Remember this is the pressure that they tend to sit at when there is low or no demand - if you are using the heating or hot water then you may see the pressure increase. An increase of more than 1 bar when the heating is in use and up to temperature could indicate a fault with the expansion vessel or pressure release valve.

During operation of boiler ie when heating comes on and off the maximum recommended pressure rise should be 0.5 bar. For example if you fill to 1 bar then the max it should rise to is 1.5 as long as the expansion vessel is correctly sized and all other components are working correctly.
