got a linea 24 boiler and the pressure keep going up to 3 i then drain water off at a radiator down to 1.5 and after about 12 hours it goes back up.the heating is off so what do you suggest
Check filling loop isnt open,if thats ok either exp vessel pipe is choked or faulty expansion vessel.

If it is not the filling loop passing it is a faulty hot water heat exchanger. Thi is fairly easy to remove and is detailed in the manual.

Sounds like the boiler is filling itself via a dodgy fill loop. Is there a braided hose of sorts attached to the mains cold water and heating pipe? This might be passing, filling the heating system up.
