The issue now seems like the temp on stat is reached but flame does not go off on the stat and therfore the boiler wants to fire up every few minutes but I I increase the temp to say 20 from 18c then the boiler remains fired up until the stat shows it has reached 20c and again the flame remains on display at that temp level
Do you think that if I completely turn the HW off from the timer and then run CH on its own to see if the flame goes off as is there even a small chance that the hot water valve is still calling for hot water which is why the boiler fires and cuts off and not warming the rads to the temp and maintaining them on what has been set on the stat? That may be one possibility to maybe find that it is still the HW valve that's the problem.Tbh don’t have a clue then as it sounds like the stats are working
I have baxi engineers coming out tomorrow as boiler has parts and labour warranty cover so will see what they diagnose as the problem and get back on this. ThanksYou would be better to set some times into the programmer for central heating and check when the Heating is up to temperature to see if the boiler goes off if your on a constant setting you will have a permanent red neon light on the programmer monitoring a call for heat , faulty motorised valves are quite common and it should be simple to diagnose if the micro switch is not making and breaking correctly .
