Should water recirculate thru the header tank ?

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)

No.

It's called pumping over, and is a bad thing since it introduces air into
the system causing corrosion.

Try reducing the pump speed. If the upper rads don't get hot after this,
the system probably needs balancing. See FAQ.

No. Definitely not. Never.

It is pumping over. The waterfall will absorb oxygen from the air and
acrry it into the system where it will corrode the inside of the
radiators.

It needs sorting out promptly. If you leave it, it will become new
radiators, powerflushing and still need sorting out. I couldn't suggest
the best way of doing this without examining the installation.

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.

Thanks to all who replied, I'll slow down the pump and bite the bullet and get
the whole lot sorted, I'm guessing that the pumping over is probably made worse
by having the upstairs rads all turned off ?
