Hi, I have a 7 year old Ferroli that started to gradually lose pressure
earlier in the year, but not so much that i was concerned. After switching
back on after summer it's now got to the point that when it has cooled down
after the heating has been on it's generally lost between 0.5 and 0.75 bar
on the pressure gauge and hence I have to re-pressurise every day. I've
checked under the floor and have no ceiling damp spots so I'm pretty sure
there isn't a leak. Any suggestions? Thanks in advance

Hi Ade

I have exactly the same problem you describe so hopefully it's the same cause. If you find out could you please email me . Likewise if I find out my problem I'll let you know and everyone else on this great forum

All the best Ian
