VOKERA BOILER. LOSS OF HEATING, HOT WATER FINE?

[URBANSOLDER]

Good afternoon,

I have a vokera boiler that works fine except!!!

Ie the hot water side is find no problems. The concern is that the heating works fine and then for not reasons stops usually towards the end of the day? I notice that he programmer called for heating still but rads are cold? I then by process of elimination found that if i turn on the up stairs hot water tap and then off again, the rads get warm and the heating works on as well as hot water, this is quite a constant problems so every morning for 4 day now i have had to get out of bed and put hot tap on to start the heating, then all is fin until the next day or late in the eveniing of the same day?

any ideas. please

I have totaly drawn a blank in the model and left the manual in the van with is now being serviced. I will check when i get the Van back.

I thought it my be a comon question as i have found many items about having heating but no hot water, but i could not find any the other way round, which is what is drawing me the blank? realy for most of the the this system works great.

VOKERA ECLIPSE E.S.C

i have not had the misfortune to work on one of these abominations in some time. they are awful overcomplicated boilers with poor user/engineer controls.

you might struggle to get anyone to even look at this nightmare.

Well thats not good news,
The system seam to be ok at the moment but I know it going to repeat the fault?

Any one got any ideas on what could be the fault, is it a faulty, diverter valve?? these normally are suggested when heating works but not hot water but i am the other way round?

The system looks quite simple? but from your comment I am now very concerned and am thinking of pulling the whole system out?

This does seam a bit rash as it is working at the moment?
would you suggest a maintenance contract? while it is still working? who with?

Any one can i have some advice on service contract for vokera or what could be the problem , or prevention i could do to stop it happening again, it working ok again today but have a feeling that it is not going to be long?? please please please help.
