You dont need a 2 port on the ufh if there is a relay built into the ufh controls, this is a diagram from nu heat which uses low voltage stats/actuators and a relay to switch the boiler.
Indeed!
apologies Picasso quick glance and thought they were manual valves,
that'll learn me!........ I'll get my coat.... lol

thank you old man, I`ll take that as a compliment

Cylinder return is fine where it , piped back to common return so not a problem.

Well, here's one that'll not win the major prize.............
You'd be better sticking to the washer changing son or mixing grout..............................

............& i thought you've been in the game for 40 years? , obviously not , or maybe you have learned nothing? .....................if you can explain to me how reverse circulation will be an issue in that pic then i'll eat me hat.......................just remember , for reverse circulation to take place the cylinder return has to be connected back into heating return BEFORE the last radiator connection.
, cap in hand deltaT? Suggest you change your username , the more you post the dumber they read.
What's the phrase? , oh yea 'theory is mince'

Sit down by me & kiss my ring, don't speak my son - as you know nothing. Listen & you'll learn at the feet of a Master(Plumber).
First fault on the system;
If you don't have the HW R connection nearest the boiler on the common return, then you'll get back circulation to the radiators in the Summer, via that return, when you are calling for HW only.
As someone pointed out above. But don't worry about it son, even I made a mistake, once.
Now, you try to get all the others son, remember the major prize!!!
Oh, enlighten me my child what is your background?
Are you a CC/CCC by any chance?

I think you'll find I never stated theory is mince. Theory is theory not practise. It's fine for some Design Engineer to spout on about theory, but putting it into practise & a thing working, is a whole new kettle of fish. Without a practical knowledge all you have is theory.
Thanks for taking the time to reply to my posts.

master plumber
replace plumber with bater
will be nearer the truth
The wiring is a side issue.
Its the piping arrangement thats not totally conventional.
Possibility of reverse flow through the hw circuit or unwanted gravity circulation or the two circulators fighting for a supply of inlet flow.
S plan plus would be better imo and the primary circulator shifted to the primary flow and a by pass valve fitted.
Not all blending valves will mix correctly with no positive pressure on the hot port of the valve which is why most arrangements will have a primary pump.
Been there and got the T shirt.
You can check with the manufacturer of the blending valve though as not all are designed the same, or as was pointed out earlier try it and see what happens which is easy to do.
And rules out questions later like " help help, i've just spent £500 quid wiring my ufh and its not working, what should I do? help help "
What ufh package is fitted?

As I said , look at the picture again
....zone circuit returns can be piped back to common return in any configuration , be it first , middle , last back to boiler................problems will arrise if returns from radiators go astray & are piped back into common return. If using a LLH/ring main where would you suggest the HW primary return be piped back? closest to the primary return from boiler/s? , anywhere on the header? , furthest away from primary boiler return?...............
makes no fookin difference. Playing a game with a fool is of no interest to me , i have better things to do.
Left school at 18 & emptied bins for 10 years , decided i'd had enough & went on a 3 month plumbing coarse , into my 2nd month now , i'm so exited.
You have an awful lot to learn DeltaT with so little time left.
