Hi,
My potterton performa 28i is sick!! It is continually losing water out of the what I would call the overflow pipe (about a litre a day) - thus needs topping up via the filling loop at least once a day usually more. The engineer has changed the safety value twice, the overheat thermostat, the diverta switch and nonthing has help. I have even pumped up the pressure vessell to 1 bar.
The system pressure guage will continually fluctuate. When i have filled it up the system with water to 1.5 bar when the heating is on it will go up 3bar and drop back down until empty!!
Any ideas?? Help!!!!
