Your electrical bill

Post by ebohling »

i know this is nearly impossible to test with the dozens of variables, but was just wondering (to myself, so i thought i would ask out loud) how the mini-VII was going to impact my electrical bill. not that i really care; it was just a curiosity. i know it would make a diff 15 vs 20amp mode. i'm running at 15amp and will keep the boiler off most of the time due to my spro desire, not a milk-based drink. again, just curious and talking out loud. ;)

You're basically running Rancilio Silvia specs with the Mini's group boiler only. When you turn on the steam, the numbers go up but you'll hardly notice a spike in your electric bill.
I didn't notice a huge increase in my bill and I'm approaching 1 year with my VII and thousands of shots fired.
Chas did a power analysis some time ago and posted it on the site. I think he's working on another one with a Kill-a-watt to get some new numbers.

Your electrical usage is unrelated to whether the machine is running in 15- or 20-amp mode; it uses the same amount of electricity. The only difference between the two modes is that in the 15-amp mode both heating elements are prevented from running simultaneously in order to keep the total load within the capacity of a 15-amp circuit. The brew boiler is given priority, but as soon as it cycles (typically tens of seconds per cycle), the heating element in the steam boiler is powered on.

In equipment of this size, total energy usage is directly proportional to the total heat consumption/loss of the unit, not the input wattage.
