Mixer Valve for UFH

    I'm installing UFH with a new gas condensing combi boiler. The boiler water temp is adjustable from 30C to 80C. The boiler will only be used for the UFH (i.e. no rads or DHW).

    The question is do I need to bother with a mixer valve or can I just run two manifolds directly off the boiler with the one pump, as you would with a radiator system?

    Thanks.

    It would be far more efficient to get the boiler to output the right temp rather than getting a mixer to do it. Would encourage the boiler to condense
