I have just upgraded from a Vaillant Turbomax to an Ecotec Pro 28 condensing boiler.
I am wondering why the boiler becomes active for a short time when I run a cold tap.
It does not fire up but a pump or something runs for about 10-15secs when the cold tap is shut off.
Is this normal?
Running a cold tap had no effect at all with the Turbomax.
