Had this problem some years ago, Twas a very, very slight leak where the CH hot came out of the boiler. Because it was hot, it was evaporating before it could drip off the pipe. Only found it one morning because the heating wasn't set to come on.

I’ll have another look. I really need them to leave the ch off but it’s freezing so no chance of that
It’s not an emergency so I may leave it until better weather
Cheers all

Micro leaks can evaporate on hot CH systems & a couple can show up a small system pressure loss. Are they topping it up when the system is cold? What size is the expansion vessel? They’re not topping it up The expansion vessell is 28l I think Decent size So, they’re just gauge watching Rocky?  .........Hmmmmm, not good having a gauge watcher🤔🤔🤔 28Ltr expansion vessel on an 8 radiator systems, are you sure? !!! How much are they losing in a fortnight Rocky? |
