Should water recirculate thru the header tank ?

NO


I ask as I was up in the loft last night and every time I could hear the
boiler
fire up for the heating, what looked like a overflow pipe starting
trickeling
hot water into the header tank.

Is this as it should be or is it yet another problem made for us by the
Yeehaa
plumbing company ? (remember the plumber who got caught ****ing in the
flower
vase, he installed our boiler)

Try reducing the pump speed but if this results in loss of performance of
far-flung radiators put it back. It may be possible to simply extend the
loop of vent pipe so it is higher and hopefully the trickle will not be
pushed over the loop.
