I saw a review on Youtube (from kaffeemacher.ch) and learnt that a warm-up cycle with 5 espressos and both boilers consumes approx. 0.2 kWh, 0.13 kWh with only one boiler. Furthermore, a warm-up takes between 15-25 minutes. 30 minutes after an extraction, the machine goes into standby mode, whereupon a new warm-up cycle is required. Now I ask myself the following questions: 1) What does the machine consume in standby (in watts)? 2) What does the machine consume during the warm-up and during an extraction (in watts)? 3) Can the 30 min to standby be extended/adjusted? 4) Do I have to wait for the complete warm-up cycle (15-25 min) if the machine has just gone into standby (e.g. after approx. 35 min of inactivity) but still has residual heat? 5) Is there some kind of shutdown procedure that has to be waited for before disconnecting the machine from the power supply (e.g. you have to wait until the machine has switched to standby mode)? 6) I would like the machine better in black, but I think the white wood is just awful! I have seen that you can buy the wooden parts. Can anyone tell me if you can order the machine directly with the type of wood you like best? Thank you very much! :-)
