When the temperature of the steam is higher than the saturation temperature, then the state of the steam is referred to as superheated. But it's only to assist in heating the water of the already exisiting hot water heater. An example of this type of process is the heat exchange between air which is used as a coolant and hot fluid that is passing through the coils where the air does not come in direct contact with the superheated fluid, but the heat is transferred from the fluid to the air through indirect contact or convection mode of heat exchange.
