Many thanks for your help twgas. Cannot understand why it felt dry after boiler turned off for a couple of hours. Could it just leak when boiler is firing up. ???
The pressure gauge on my Linea 24 combi is losing pressure over period of a few days. (From 1.5 to 0.2bar)
There are no signs of leaks and the Safety valve discharge line is bone dry.
I have taken the covers off boiler and inside the combustion chamber at the rear the side insulation panel...
