Sizing a circulation pump for a 4 zone S...link type system

    The system has 4 zones and one of the pumps has failed:
    it is a Grundfos 25- 80 which retails at 330 euro
    the 25-60 retails at 140 euro



    The zone in question comprises six 6kW Solo fan assisted radiators that are all on the ground floor: each radiator is connected back to a UFH type distribution manifold.

    Will the 25-60 do the job?
    Thanks
