Vokera 25HE fan not running (not fan problem)

If the OH stat keeps tripping, there will be a reason behind it, for example lack of circulation leading to overheat.
You need a GS bod to look at it for you, and find the cause.

Thanks for the advice. Recently I had a booster pump installed on the main water flow from a professional plumber. I was not expecting it to interfere on the heating water circuit once it is isolated.
