Hi,

I need to repressurise a sealed system after a leak (leak is fixed)
and I would like to know if this has to be done when the system is
cold since SWMBO does not want the CH switched off at all today! It's
down to 0.8 bar ATM.

TIA, Mark
TBH its not critical. I generally go to about 1.5 bar cold. Probably too
much, but it seems to take it.
