That puzzles me as well. If the F/E tank is at overflow level there's something wrong. At least it needs bailing out, and the ballcock adjusted, and check the valve is closing properly.
Central Heating F @ E tank feed pipe gets too hot

It's a bit higher than you'd like, but about body temperature. Perhaps the pros on here can say if it's unusual.
Replied to Johntheo5 on this.

Sometimes, if there's a blockage in the cold feed the level can rise to overflow point.
I was referring to the temperature

Are we really @ 4 pages on this now.... jeesh.
@Stuck1 - in post #28 with the pic of your setup, the pump head orientation suggests it is flowing upwards towards the AAV and then feed and vent - as was asked by @dilalio in post #31, what direction is the pump flowing?
As was also suggested the original setup pic post#31, the pumps orientation would have the flow heading left and downwards towards the ABV and zone valves

It's the most obvious thing to check... Occams razor.
Not wishing to question but are you sure because the pump orientation as it looks in post #28 suggests that it's flowing upwards.
If you look at the pump orientation in the pic in post #30, the pump is flowing left. So if nothing has changed re the pump and its housing then that pump is pumping upwards not downwards. That would explain a lot
Just to prove I'm not going mad - can someone else please look at the 2 photo's post #28 and post #30. If it's the same pump and if the original location in pic 2 post #30 is correct and the pump is flowing left towards the ABV and the 2 ports, then if the pump is the same in pic 1 post #28 then looking at the pumps orientation (writing/cable entry etc) then it has to be flowing towards the feed and vent or am I just seeing something completely different than everyone else?
I have a UPS3 on my UFH - the pump - as it is oriented in post #30 with the writing the right way and it pumps upwards towards the top of the manifold and so does every other UPS3 that I've come across, it's a Grundfos standard orientation. Unless the pump head has been turned 180 Deg for absolutely no reason.
I'm seeing the same, and it looks as if the head has been turned 90 degrees.
Yes, Every pump of whatever make that I've come across will have its arrow pointing upwards (pump pumping upwards) with the pump head "label" etc as you would expect it, readable etc, when you take it out of the box.
The UPS3 has its cable hanging down from the left.
If you installed this pump to pump downwards then the label will be upside down and the cable will hang down from the right, it will work fine this way but looks terrible and makes changing settings difficult, all that needs to be done is to remove the 4 stud bolts holding the head to the pump and turn the pump head either 180 deg left or right and the cable will again hang down from the left with the label correctly displayed.
This pump originally was installed horizontally so the head was only turned through 90 deg so only required another 90 deg turn when installed vertically whether pumping upwards or downwards, this is my take on it. I have installed 4 or 5 Wilo Yonos Picos on Heat pac Firebird OF boilers and installed them all pumping downwards into the boiler return, I just installed them with the arrow pointing downwards and simply swung the head through 180 deg.
@ Stuck1 says "The pump flow is pointing down" which I would interpret to mean that the arrow(s), (there is one on either side of the pump BODY) are pointing (correctly) downwards but he might confirm this, once and for all.
You can see the arrow on the rightside of the pump body, below, pointing downwards.

He says the system is working well (apart from the issues under discussion). I doubt that would be the the case if it were pumping the wrong way. Flow would be the wrong way through the boiler, apart from anything else.

No it doesn't/wouldn't, it just means that the feed and vent could now be in the wrong position, it doesn't show where the 2 port valves/ABV are now, that could all have been changed too and the pump is pumping towards them as it should, so flow for the boiler etc could be correct.
Indeed @Johntheo5 , in your pic the arrow is pointing down and the pump writing is upside down, so if you turned that through 180 deg the writing on the pump would be the right way up and the flow would be upwards, as in the OP's pic. That's the way all the grudfos and others come out of the box so unless the OP's plumber has taken the pump head off the pump body and turned it 180 deg (for no apparent or fathomable reason) then it's pumping upwards, hence my question
This is the way every UPS 3 and just about every other pump I can think of comes out of the box, writing the right way up - flow is upwards
