7:30am - 52 lounge, 55 bedrom, coming up but slowly as other rads in system start shutting down on thier TRVs as rooms reach temps...........downside of all this is I now have a boiler pressure of 2.7bar!!!!!!!!!1 up from 1bar cold. Clearly increasing pump speed to 3 with current lockshiled settings (most are throttles way down) is raising boiler pressure.......or coincidental problem with EV pressure (which you say I cannot touch evn thought shraeder valve can be seen at back / top of boiler).
Not sure how fast the boiler pressure came up this AM, will get wive to turn on heating from cold this afternoon and watch gauge for 10-min to see if it shoots up (indicating EV issues) or rises slowly over an hour, indicating lockshileds too far shut on too many rads issue
Next step - open lockshileds downstairs more to reduce system resistance and max boiler pressure on pump 3 setting, or just call out an engineer (I know!)
