Warming (general)
Most Espresso machines brew at 92-96C. If you simply pour boiling water into a cold Presso the water will be far below this temperature by the time it meets the coffee. It will be further cooled while pouring from the portafilter basket through the portafilter and is unlikely to taste good.
How much you need to warm it depends on the ambient temperature and the temp of the water you are pouring into it. If you are making espresso in your unheated basement in the dead of winter you will need to do a fair bit of warming up. If your Presso has been sunning itself at the beach you could probably get away with no warm-up at all.
In any case the water you use for brewing should be as hot as possible, so work out a way to pour just-off-boiling water directly into the Presso's pressure chamber.
I've prepared two methods, for "The Dead of Winter" and for a comfortable room temperature environment.
