Posted Sun Nov 11, 2012, 2:54pm Subject: Energy Consumption for the Rocket Espresso Giotto Premium Semi Commercial espres
Hi, I just bought the Rocket Espresso Giotto Premium Semi Commercial Espresso Machine, and would like to know exactly how much watt this will use if kept turned on always.
I usually brew 5-10 cups a day.
I got this info for the machine: Measurements: Height - with Cup Warmer Guard: 15 1/4" - w/o guard: 14" Depth - with filter handle: 22" - without filter handle: 16 3/4" Width - Drip Tray Front: 11 3/8" - Wands at maximum extension: 18" - Back Side Widest: 13 1/4". Power: 110 Volts, 60 Hertz, 1200 Watts, 15 Amp. Weight: 46.3 pounds (21 kilograms). Water Reservoir Capacity: 2.9 liters. Boiler Capacity: 1.4 liters. Ulka EX5 Brass Pump: 41 watts (please note that there is very minute difference in noise levels when compared to a 52 watt pump - there is practically no difference in espresso quality found in the cup)
As I've read online, the power consumption differs a LOT compared to when brewing, and when it's just keeping the warm water at the same temperature.

Keep in mind that this machine consumes 1200w when the boiler is heating, around the same as a small vacuum. Roughly, the same as a dozen desktop computers. Those run around $15 a year each to operate. You'll have to calculate the wattage versus how long you plan to run the machine and your area's rate, to get the final cost.

There is more to it than that, it depends on the insulation of the boiler, the boiler on/off cycle time, the time of day as the energy rates change depending on the demand of the whole electrical grid, and on and on go the variables.
Each person is different and the only way you can know exactly what your machine costs to run is to measure what power it uses through the day, the time of day, the rate per KW at the time it is being used. A worst case can be guessed at by measuring how much power your machine uses in 24 hours then multiply that by the most expensive rate you are charged. The truth will be someplace less than that.
