Temperature of steam versus water in a boiler - Espresso

2009-10-17·How much of a difference is there in the temperature of steam in a boiler compared to the temperature of the water? Why I'm asking is to find out how critical it is that a temperature probe be immersed in the water in a boiler. I'm thinking that the temperature level can change, so does the probe have to go really low, or is
