Air in boiler Whooshing

[Diy592]

I have recently moved into a new flat and have been having issues with the heating. The bottom of 3 of the rads were stone cold when I first moved in, I blead the rads, checked balance, no change. So I put a cleaner in the system, left it a week and took the suspect rads off and tried to flush them out, some sludge came out. Put them back on blead the rads and now the boilers making a loud whooshing noise, I double checked all the rad were blead, then I pressed the bike pump thing on the boiler and a LOT of air came out but the boiler still seems to have air in it and I can hear it gurgling. Any ideas on how to remove the air? Boiler is Worcester 28i junior and would like to get a year or two out it at least before replacing.

Yes I pushed the pin until water came out.

thats the expansion vessel and its supposed to have air in but not water so theres a problem

your best option is contact a local heating engy and tell him what you've said here and youve had problems with the boiler

Will this re-pressurise itself ?

No , you need a heating engineer mate

 

[ShaunCorbs]

Sorry to say no and as there's water there no point also get him to look at your noise / air problem as well whiles he's there

You definitely need a GRS you have already done more than you are legally allowed and it proves a little knowledge can be dangerous do not use your boiler untill a engineer has attended you will damage the boilers heat exchanger cheers kop

This to me sounds like a 'wind up'

Someone is trying to play funny buggers!
