Ufh manifold, blending valve with ASHP.

Ufh manifold, blending valve with ASHP.

So all my bits turned up for my ufh, but I’m confused with the manifold layout, I was told if I’m fitting an ASHP I don’t need a blending valve, is this right.  Who has a blending valve and who doesn’t.    Confused as usual. 
Blending valve ALWAYS.  You will need a low temp tolerable one such as the Ivar as normal TMV’s very much dislike low flow temps ( 30oC and below ) but these cope very well.
