Hi Dan,HB wrote:I noted that Junior was among the slower machines to warm up and recommended at least 90 minutes in the review. You have been posting a lot of temperature plots lately, why not test your assertion? A plot of the first few pulls with the thermofilter for your espresso machine being on for two hours and another series after idling a half day should settle the question (at least for Junior).
I'm on a temperature plotting hiatus. For one thing, I'm sick of doing it, and for another there hasn't been much of a response to what has been a huge "time sink," so I'm not highly motivated to bother. My experience with seals and gaskets is that if anything they last longer when the machine is on 24/7 then when there are repeated cycles of heating up and cooling back down. I've had problems with vacuum breakers when the machines were run on a timer and almost never (or at least it took 3 years) when run continuously. I am unconvinced that the savings in my electric bill would exceed a couple of bucks a month running the thing on a timer.
The safety argument is similarly uncompelling. If the machine is well taken care of I think leaving it on is as safe as leaving your water heater turned on, or the furnace, for that matter. Why the emphasis on potential danger from an espresso machine? Are they so much more "dangerous" to have around that they need special precautions? Why on earth don't the insurance companies have an exclusion in their policies for damage done by espresso machines? Boggles the mind!
So, I'm not motivated to test this at the moment.
