ideal combi boiler mini c32

[sided]

Got the above mini c32 ideal boiler .Connected to 9 Rads & running it on 1 bar pressure but, when i push the heating up to under 1/2 the pressure willris to 3 !! Iunderstand it should be lower than 2 . therefore i can never run it on 2/3 or max heat !

Check your expansion vessel. Dump system pressure, put foot pump on and adjust accordingly. If thats ok it might be a blocked flexi to the expansion vessel.

Spot on m8 .Its expansion vessel . Tested it & water poured out of the valve ,as there's no tomorrow.Do i go for external bottle or change the original?How much are the x vessels any way? I think the xternal bottle is about score.

How do i remove the original 1 out ? Is there any manual or video ?

Don't do gas boilers only the oil, I know on here the recommendation is to fit a new external one. Oils always a lot easier to change (unless its a grandee) little bit more generous with the room.
