I don't think we can make the assumption that that's what Rossi meant. I suspect he meant from a cold start. It probably hasn't occurred to him yet that someone might leave it running continuously at a low rate. I think he needs to be asked if there an 'idle' setting that will allow quick heat up to full power, and if so, how much power would be produced during 'idle' mode?
