Was trying to stop the boiler being noisy and found that pump on setting 3 was making the noise so changed it to 2 which cured the noise.
But now since I've done that noticed when the boiler starts up from cold it shorts cycles for the first 30mins or so 10seconds on 10 seconds off but after that seems to run fine full temps on radiator full hot water.
Know I don't know if it used to do this before and I've only noticed beacuse I keep looking at it and checking it, is this the norm??
And if not will it do the CH any harm would prefer to run like this to keep the noise levels dowm
It's a Gloworm express 100 combi sealed system.
Thanks.
