Hi all,
I have a Santos unvented system, with a Viessman Vitoden 100 heat only.
The heating has its own external Exp. Vess, and the DHW has its own white slightly bigger Exp. Vess.
I live in central London with very hard water, about 400 parts, and when I have a shower and someone else opens another taps the pressure drop dramatically. I remember when I moved in 4 years ago, it wasnt like that...
So I can assume that the White santos Exp Vess either needs pumping or replacing. What tests can I run?
If I close the mains coming into the system, then open all taps, they stop after 5 min. Do I then get a foot pump and pump to 3.5bar?
any help would be great...
