Sounds like a good stepup from the gaggia baby,
re the 1700watt element, my cimbali has an 1800watt and it cycles on for about 10% of the time, ie 6 secs on evey 60 seconds, therefore the equivalent of a 180watt light globe.
For my usage pattern I dont need to leave it on all day, about an hour in the morning and maybe the same in the afternoon. It comes up to temp pretty quickly (2.5ltr boiler) but I like to wait at least half an hour before pulling a shot, I imagine the Epoca would behave similarly, btw what is the boiler size??
All the data Ive seen indicate there is liitle to be gained by extending the warm up period beyond 45minutes
Good luck with your purchase!
