Boiler clock losing time

[Davon]

Hi
I have a Main Eco Elite boiler which is three years old with a Gassun mechanical clock fitted . The issue I have is that it keeps good time during the day but loses an hour (sometimes two ) overnight !
This is rather strange as if a faulty clock I would expect it to lose time constantly .
Any advice would be most appreciated .
Thank you

Simple answer replace it as anything mechanical it can wear . Kop

These have always been bad. Eventually they always lose time.

As all previous folk have advised times up for the clock

mechanical so probably parts worn or teeth missing on cogs that take it through the night

Thanks that makes so much sense. Guess it's time to get one and fit it.
Cheers
