Hi All
Have a megatech HW cylinder heated by a Vailant ecotec 428 boiler.
I've noticed that the boiler's water pressure increases from 1.0bar cold, to 1.6bar when hot - is that normal, or does that indicate a fault with the boilers expansion vessel (for example)
Also, if i turn the HW and CH off for a few days, when I turn back on, a small amount of water is discharged from the system - which could be from the CH/HW system, or possibly from the megaflo heating from cold? - They discharge out of the same pipe.
Perhaps the system is just slightly too full at 1.0bar cold (the boiler is in the attic, at the very top of the system).
Or perhaps this indicates a problem somewhere?
Thanks!
