Why does Worcester Bosch 35cdi II lose pressure constantly?
In general the system pressure went down from 1.5 bar to 0.8 while running continously for 12 hours. It lost more pressure when it was switched off and cold. The engineer checked the charge on the expansion vessel. It was “a bit low”. It was topped up expansion vessel to 1 bar. The system was repressurised to 1 bar cold. Replaced PRV.
What should water side pressure be on Worcester Bosch?
The water side pressure is pretty flexible, although I personally don;t see any reason why it should be more than 1 bar. The lower it can work at the better as that simply leads to less stress on the system, and 1 bar is well over the min required (around 0.5 to 0.7bar).
Why is my Worcester Bosch boiler losing pressure?
Hi, I have a basic Worcester Bosch Greenstar combi boiler. It is recently losing pressure on a daily basis: I top up with water up to 1 bar, the boiler heats the house; after the boiler has cooled, pressure has fallen almost to where the gauge shows red.
Is there a remedy for Worcester Bosch pressure loss?
It would be great to solve the problem/mystery of this drip which seems only to occur in the months when the central heating is used, and not in summer. Since the increased need to top up the system on a daily basis, there has been no dripping from below. Is there a remedy for both these issues?
