ChatSuperheated steam - Wikipedia
Superheated steam is a steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured. The steam can therefore cool by some amount, resulting in a lowering of its temperature without changing state from a gas, to a mixture of saturated vapor and liquid. If unsaturated steam is heated at constant pressure, its temperature will also remain constant as the vapor quality increases towards 100%, and becomes dry saturated steam. Continued heat inpu

Yes, there is both a practical and a safety issue with the maximum water temp in a radiant floor. The floor temp shouldn't end up much warmer than your desired air temperature, and once the temp in the slab is stabilized, the feed water normally wouldn't need to be very hot, maybe in the 100-120 degree range, depending on how deep they are and how close together, and, how well the slab is
ChatSteam Calculators: Boiler Calculator
Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 12.3 psig. Temperature = 319.2 °C.
