    It looks like an automatic by pass to stop the underfloor heating getting to much hot water and doing damage by over heating and getting heating water at to high a tempature. That's my opinion going on the fact that its only on a half inch pipe.

    Any other views anybody?

    That looks like a thermostatic valve to me. It's a bit of a queer manifold set up.

    It's an injection control valve. It mixes in the flow temperature of the boiler to maintain the UFH circuit set temperature of the ICV.
