    radiant wont heat

    i currently have a plated radiant floor system with 4- zones, evenly divided. the 2 end zones are identical with 4-loops each 150'. we piped it in reverse return.the farthest end zone and the 2 middle zone are perfect 70deg, the other end zone wich is over the boiler and closest won't heat above 64deg.i have raised boiler water to 145deg in an attempt to raise this zone up, it did help somewhat and i have taken the boiler off reset.none of the loops exceed 150'wich should be ok for a 007.
