LINEA VOKERA 24

[CRENWICK]

Pressure was showing at below 1 bar so topped it up. System went up to above 3 when heating was running (above red line) which has freaked me out a bit. Is there anyway to get the pressure back down a bit. Its sitting at 2 at the moment, but it hasn't cooled down yet.

Open an air vent on a rad and catch the water in a bowl.

 

[Agile]

Set it to 1.5 Bar with the rads cold.

Put heating on and watch the pressure increase. If it goes above about 1.9 Bar then the expansion vessel is failed or needs recharging ( see FAQ ).

Boiler will have dumped excess pressure to outside. A valve within the boiler will open at 3 bar to do this.

Getting the boiler serviced will more often than not, cure operational defects like what you have on your boiler

 

[CRENWICK]

Many thanks didn't get the chance (or need to) reduce the pressure. Its now sitting at around 1 when system is cold but going up towards 3 before I'm freaking out and switching it off. Turning hot tap on seems to bring it down a bit. How long can the system survive on this basis, as you can imagine I'm gutted that this is going to cost money at this time of year. From what you've said it sounds like it could be the expansion vessel. Can anyone tell me what financial damage getting this part replaced is likely cause - have an engineer who will do this but just want approximate figures before I call him.
Thanks.

If your feel it maybe the EV, then try that first, for FREE. Thanks agile.

Read the FAQs at top of the page. There is a step by step guide on how to check and repressure your expansion vessel.

 

[Agile]

Try repressurising first.

However, on your model its just as common to find the internal communication pipe to the EXV is blocked.

Repressurising free as a DIY.

Eng to unblock the comunication pipes perhaps £80-£120

Remove boiler from wall and replace EXV perhaps £160-£260. That should really be a two man job if lifting weight limits are followed. If they are not then it may be a crushed foot if its dropped or a hernia or slipped disc or all three.

or perhaps an easy job if there is enough space above the boiler to remove the EV without taking the boiler off the wall.

 

[Agile]

I never seem to get those easy jobs!

Well, I have to admit I did get just one. But all the others have been an off the wall.

One where the cust helped me was very quick but that was because the flue was not cemented.

OP, there is never a good time to spend money on a boiler. Result is, no boiler service often results in problem you are having. A service, not only would indicate what is root cause of the malfunction, but also fix other bits that might cause problem later.

i would certainly ask the cust before lifting the boiler off the wall. most are not bothered if it's in a cupboard.
