Not a controlled scientific experiment by any means, but for those completely in the dark about how much electricity is used to leave
a machine on this may shed some light.
The figures are to leave it idling. Actually brewing will alter the figures to take into account the pump etc but given the few coffees brewed daily shouldn't be much higher.
Machine here is a Grimac Eclisse 2 group.
Ambient temperature 18°
Amps: 10.5
Volts 249
Power: 2614 watts
Heating element on: at 0.6 bar
Heating element off: at 0.8+ bar
On time: 22 seconds
off time 2 mins 13 secs
Per minute power: 43.56 watts
Per on cycle watts: 15.97 watts
So every time the element comes on, for 22 seconds, it uses 15.97 watts
In one hour, the machine will have cycled on/off 23.2 times. In 24 hours, 511 times.
In one hour, the heater will be on for 8.5 minutes. In 24 hours, 204 minutes, or 3.4 hours.
the kilowatt/hr price of electricity of course varies according to where you live and from whom you buy it.
I'm allowing 35 cents per kwh.
So, in one hour idling the machine will consume 370 watts. In 24 hours 8887 watts.
Cost of electricity used is 12.95 cents per hour. In 24 hours $3.10.
Power was measured with a digital clamp meter. Voltage is given by my grid solar inverter.
