Sounds like a control issue. Good engineer will sort it for you.

I agree with SimonG. It does sound like a control problem and a GSR engineer will fault find the offending part and replace.

hi to all i have a new problem actually dont know is it a problem.i have ideal logic +15 condensing boiler.he make some noisy when starting.its like his normal sound but louder then usualy then for a few second like a vibrating sound and then he work normal.is that some problem or its just because its all cold or what?

 

[melany]

ok quick update its like silent vibration heard twice for about 10 seconds and it apears 15 min after boiler starts.and then stops.should i be worried about to call a engeenier or its ok?because is silent you can hear it if you are next to him.
