    Re: For how long do you keep you machine switched

    interesting TG - youre saying that the difference is minimal.
    i was concerned about carbon footprint - i guess there are better ways to reduce emissions

      Re: For how long do you keep you machine switched

      I did a search and found this thread...
      http://coffeesnobs.com.au/YaBB.pl?num=1219471403/0#0

      Not the one I remember, but good info there.
      When time permits I think I may do my own calculations.

      These devices are available if youre really worried - Power usage meters for individual appliances.

        A Power Bill is one indication of carbon footprint contribution.
        So we were talking the same thing.

        Take a shorter shower or plant a tree then you wont feel guilty drinking your coffee.

            Make sure that tree has a diameter of at least 3 centimetres per cup...

            Facts About Coffee
            Every cup of coffee consumed destroys roughly three square centimeters of rainforest, making coffee a leading cause of rainforest destruction.
            I wonder where they get their facts. Id like to know if its right.
            Looking at some of the other facts on that site, I have my reservations...

            http://www.merchantsofgreencoffee.com/all_about_coffee.html
            As with freshly baked bread, fresh roasted coffee has a very short shelf life - maximum of five days - regardless of packaging.

            Electric hand grinders are available for about $20.00. Mortar and pestle or blenders also do the job.
            How many CSers use a mortar and pestle to grind? Any?

                anthonyd - and other CSers who leave their machines on all day and havent noticed a spike in elec. bills -

                im interested to find out how a machine left on all day doesnt increase power consumption compared to having it in in the am and pm? i understand that most power is needed for the initial heat up, but even still, with the thermostat running all day clicking on and off surely must require more power overall? (not digging at you, just really curious)

                cheers

                Aaron,

                As i said i used my power meter to measure this - i dont remember the actual figures but the difference in power consumption (in kw/h) was neglegable for the whol day vs switching on twice in a day.

                  cheers anthony!
                  that settles my conscience - i wont feel guilty leaving my machine on all day just in case someone pops in or if i come home early from work, etc.
                  great news!

                    Mine stays on all day aswell, when I am at home. I switch it off at night time and when I leave the house for long periods.

                    The thought of having it on and something going wrong when Im not there, spooks me.

                      do you also worry about whether or not youve left the iron on, or left the front door unlocked when youre out of the house?  :

                        Actually the other half does. He is OCD. Will make sure the front and back door IS shut....and does this several times, aswell as making sure all lights in the house are turned off too.

                        Makes me : my eyes too.

                          and given his "OCDness", does he have a super consistent (almost ritualistic) dosing and distribution technique?

                              re: the power consumption, I measured the duty cycle (on time vs off time, for those who arent sure) of the VBM last night once it was up to temp.

                              Switched on for 15s, then switched off again until 2m35s, then switched on for 15s, and so on.

                              So its on a 15s/155s = close enough to 10% duty cycle. This would suggest to me that its 1800w element is on 10% of the time when up to temp, or the same as drawing 180w continuously.

                              Will do some more measuring of on/off times while the machines warming up..
