hello can somebody help, i hsve a baxi 105e boiler, when the bolier is cold the pressure is o.5bar, when the heating comes on it reaches just below the 3 bar mark, when i turn the hot water on the pessure moves above the 3.0bar mark and water comes from the PRV. I had the PRV changed on the boiler two weeks ago, so i dont think this is faulty. Do you think it could be the pressure vessel on the bolier?

expansion vessle need`s pumping up
is the easy to do ? and what pressure should it be pumped upto ?.
Reasonably easy to do:-
1-remove all pressure from system when it is cold via a drain cock or rad bleed screw.
2- Locate exp vessel schraeder valve (like your car tyre) at the top rear of the boiler.
3- attach a pump and inflate to between .75 and 1 bar
4- Refill system via fill loop and bleed out air.
There is a bar across the back that can be removed to get better access to the air valve. Replace it after you've done. It is possible for a diyer but it can try your patience.
Sorry to butt in adl.
