having trouble finding the answer to this, and ive asked in 4 places
so far
could you guys take a look at your Y pieces in the heater matrix
circuit and tell me which way they go please?
in my wisdom when i replaced the matrix last year i used a T piece as
it looked better and the pipes fell in the right position, but i only
get warmth through the matrix when the stat is closed (presumable
because there is more pressure) but when the engine warms up it all
go's cold inside, presumable because I've put the T piece with the
straight edge going across the manifold and the single leg going to
the union into the manifold, i guess that the Y piece single leg goes
to the manifold and the 2 closer legs go to the 16mm heater hosed?
any info much appreciated, a picture even more so.

From distant memory water should always flow through the matrix in one
out the other.
Depending on the flap angle cold/hot releases the heat to the car
boosted by the fan.
water will follow the easiest path so you are probably correct with your
stat theory as the 'stagnant water' in the matrix will go cold
especially when the fan is run.
this may help but is for zetec.

cheers mate
its a start though i need to know specific hose routing and Y piece
location,
there must be hubdreds of Quantums and fiestas out there yet nobody
seems to know for sure?

If it's a CVH then.
One top leg of the Y comes all the way round from either a T off the bottom
rad hose or a separate outlet on the water pump (depends on car and age).
The other top leg of the Y comes from the inlet manifold.
The bottom of the Y goes to one side of the heater matrix.
The other side of the heater matrix goes back to the small outlet on the
stat housing (this outlet is before the stat).

So, is that how yours is connected ?
I don't think using a T instead of a Y or having the hoses on different legs
of the Y would have any effect on the heater operation.
I'm sure I've done both of those on various CVH's in the past.

well yes pretty much,
the only deviation i have, is rather than route the 16mm union from
pump round the cam belt cover side which im not keen on as space is
tight, ive routed the hose in front of the block (old shape pump union
points this way anyway), under the distributor round the back of the
engine to the T piece, ive no idea why this should make much of a
difference but as i said, i only get any heat on the warm up, i.e
stat closed, once open and up and running the air flow runs cold, even
when the engine is up to fan operating temperature,
the only other time ie had warmth coming out the fan on the move is
when I did a 500 mile round trip to Cumbria and on the motorway the
car got warm through the interior fan but once I stopped at a service
station (the engine is still more than warm but the engine has been
off for about 5 mins) the fan blows cold for ages, only after a
considerable time does it warm up again but this was only about twice
in the whole journey, so this is why I suspect poor flow.
the only other thing ive done is use right angle plastic hose joiners
connected directly to the matrix outlet / inlets because space is
tight in this area.
the pump / matrix / stat / rad /and all hoses are brand new, im not so
much worried about me keeping warm as i only use it in the summer, but
i wan tot know my cooling system is optimal, cheers for the input

Problem solved!!!!
after much trying and 2 different types of Y piece and 2 attempts to plumb it in I've finally got it right
i bought a genuine ford Y piece
fitted it in, all went quite neat actually
eventually i fitted it so that the long straight leg links the bottom heater matrix outlet to the water pump inlet to provide a strong draw of fluid through the matrix (the Haynes manual shows the pump to the top matrix hose but my figuring is that once the fluid cools and condenses the cooler fluid will sink lower and be drawn off by the water pump) the inlet manifold bottom union goes to the side leg of the Y since it (in theory) gets a bit more push from the pump through the block and out the union under the manifold so diverting the flow to the side leg of the Y should be sufficient.
then the union from the stat goes to the top matrix inlet to provide plenty of hot water direct from the block to the heater,
and the results are that for the first time since i rebuilt the car 3 years ago i have a fully functioning heater, there are now no air locks since the transparent 90 deg elbows i mentioned earlier on as having no blue coloring to them from the coolant now have a strong blue colour to them
so happy days and thanks for the input
