My boiler was installed in July 2021. As my boiler is in garage, I didn't notice how it sounded when it started. A few weeks ago, when the boiler just started, by chance I went to garage looking for something, I heard the boiler was very loud! Much louder than when it is in operation for a while. I went to check the gas meter and found the meter ran very fast!
After maybe about 20mins (not sure exactly), I went back to garage to hear again, found the boiler became not loud, sounded normal as I heard it before---I went to garage many times after boiler started for a while, I know the normal sound of boiler in operation. And I checked the gas meter, the running speed became slow/normal too.
After that, some days later, I went to garage a few times to check the sound after boiler just started , no matter when CH or HW started, it is always louder & gas meter runs faster, after a while, not sure how long, normally after 15-20mins maybe, the boiler sound becomes normal and quieter, and the gas meter runs slowly.
Is this normal operation for boiler? i.e. when boiler starts it is louder & gas meter runs faster; after some time, the boiler becomes making normal sound, gas meter runs slow/normal?
My boiler is not Combi boiler, it is regular boiler with water tank upstairs (unvented system)
Thanks!
