Firstly a big hello to you all.
Some Details:
Ideal Logic+ 30
Boiler situated in loft
Semi-detached 3 bedroom
8 radiators mostly small with one large in living room
Radiators around 6-7 years old as was original boiler
TVR on all radiators
Mainly plastic piping
Ariston boiler died so just been replaced by BG with one of these Ideal Logic+30.
It was all signed off but within the day of installation it tripped on "No Water Flow Lockout". It still keeps tripping no matter what we do. A BG engineer was going to replace the thermostats on the boiler but I struggled to believe that the boiler would come with a fault. I know its not impossible but hopefully unlikely. Anyway after some discussion and me explaining how we ran our boiler he concluded that there might be an issue with the boiler not being able to cool down the flow.
When we run the CH we usually only have the odd radiator say 2-3 open maybe 30-50% depending on how cold it is. Often this will be on timer too. When he heard this he remembered that there wasnt a bypass valve installed. The theory is that with the lack of a bypass and the fact there is not a great deal of heat transfer with most of the rads on low that the boiler struggles with the heat coming in and therefore trips.
Of course my first thought is why trip on flow as opposed to heat but i suppose they are related and it can be down to the logic of this particular boiler.
We were advised to keep a couple of rads open at all times to help cool the water. We did this and there were no trips for a couple of days. Last night I turned down the big rad down a little .... the other 2 were still fully open. In the morning we found it had tripped ..... it was on timer through the night. I was beginning to think there might be some merit in this prognosis but then the missus tells me she had set it to "On Constant" through the afternoon and it tripped again. It doesnt appear to trip when its switched off and we just use it for HW but i havent really analysed if it trips more often after using water but the missus thought it did.
I bled the radiators last week and there was some air i.e. 4-6 seconds out of one of them upstairs. Did it again recently and there was nothing. The pressure sits just under 2bar and sometimes a little over.
I have also noticed while its running that the status is "pump overrun".
I was going to get them to come back and fill a bypass valve but just unsure if this will resolve the issue.
Please give me your thoughts.
