Vaillant Ecotec Pro 24 boiler issue

yep but you need to bleed all rads, just let air out. do it when boiler cold, you may to put more water in if pressure drops. keep it about 1.2

you can only bleed a rad if there is air in the system.... if you want to reduce pressure you can do in the same way by letting water out of the vent.....but as already said i would leave at 1.8 as it is only rising to 2.2 when heating is on....and when engineer is in he will set it as it should be!!

only wondered cos of the whistling from one of the rads when the heating is on

 

[dancinplumba]

[dazzyboy10]

[dancinplumba]

common problem is that pressure sensor is blocked with sludge if boiler fitted to an old system without cleaning first.
