Hey everyone,

Anyone else keep their machines on for long periods of time?  Anyone notice their electric bills jumping?

So, it wasn't a great test with controlled variables, but without changing general habits, my electric bill jumped about 50-75% after I got my machine.  I have it on a timer, and previously had a schedule about like this:

Weekdays:  On for ~2 hours in the morning, ~4 hours at night
Weekends:  On all day, from around 7 AM to 9 PM
Total:  Around 58 hours a week

After the bill was high for a couple of months, wife got the idea that maybe it was the machine...I just hadn't thought about it until then.  So I changed the schedule:

Weekdays:  On for ~ 1.5 hours in the morning, ~4 hours at night
Weekends:  On for ~3 hours in the morning, ~4 hours at night
Total:  Around 41.5 hours a week

In addition, I now try to consciously turn off the machine if I know I'm done with it for the time being.  I probably save another 5 hours a week from this.

I estimate the machine is on around 66+ hours a month less than before, and in the first month since the change, the electric bill has gone back down to reasonable levels.

I'm sure some machines are bigger energy suckers than others, but wow...I have a hard time thinking the huge bill was from anything other than my machine!

Rather than relying on intuition, consider an energy-use meter.  

You may find that your bill reflected running the AC during historically warm weather, affected your bill more than your espresso machine.

Hey Rich,

That's the thing...it's been mild weather at worst...I know you mention AC as an example, but in terms of other types of energy use, AC would probably be the only other defining factor that I can even think of that would have that much of an effect on our electricity usage.  We have a Nest Thermostat, and I didn't even have the AC setting on...only heat, and that's via gas for us.

So...barring leaving TVs or lights on more than at other times...the only major difference that I can think of is the machine...

That, and I've never used an energy-use meter before =)

First, it depends much on how much electricity you use before.
And second, what kind of machines you have in your house.

Generally speaking, a home machine doesn't cost too much of electricity, unless you have a professional one.

My NS Oscar running 12 hours a day uses less than 2.4kwh if I remember my last measurements correctly.  I'm sure this could be better insulated and run more efficiently too.

If your machine is a 110V model then get a Watts-Up power meter or even the inexpensive Kill-A-Watt to measure consumption.  It's good to have one around sometimes to check equipment power consumption.  Well, at least it's good for me when I'm curious about power consumption.  (I personally use the Watt-Up Pro version and like it.)

I could swear I read from some people who measured their machines useage, that especially if you have a Pro-Sumer or Commercial setup, turning on and off can take a lot of juice as the boilers take a decent amount of energy to heat up. When left on 24/7 they used less energy, guess it could depend though.

"Kill A Watt".

This one allows you to input the KWH cost and it computes the cost, over time, of what is plugged into the meter.

I bet you did read this, as I have too, but that doesn't make it correct!  LOL

It's like the old tale that leaving fluorescent lights on 24/7 is more efficient and cost effective than turning them off when not needed.  Also not true.

When you have the espresso machine on it's running hot and the heat is lost at a more or less constant rate.  Turning off and letting the temps drop will also decrease the temperature differential between the machine and surrounding environment, thus slowing the loss or transfer of energy.  When you turn it back on it does take a long time to heat up again, but the energy consumed is less than would have been consumed to keep it at temp overnight or whatever the interval may be.

Having said that...  Cooling and heating the larger commercial machines can be problematic, increase scale, increase wear, and increase service costs.  I'm sure there are some issues with the smaller machines building up more scale too, but personally I'm not too worried over that.

Can you tell when the heating element is active?  On my Vetrano the heating element is active just under 10% of the time.  Given a 1400 watt element, that works out to be about the equivalent of a constant 120W lightbulb.  That should not cause the bill spike you are seeing... grab a kill a watt to be sure, but it sounds like something else probably causing you grief.

I watched the energy use for my machine with a Killawatt, in short, leaving on 24/7 uses about the same power as 2 100 watt light bulbs on constantly. If I remember correctly, it takes about 6 or 7 hours of on time to equal the start up power used in the first hour of the machine warming up and getting stable.

I use it every morning and very often at night so it costs me about 2X what it would if I turned it off after use each day. For me, the extra power used is worth it. You should not see that huge jump in power use unless you did not use very much to start with. My electric bill hangs at about $300 a month, twice that when the AC is on in the summer and it is 105f outside for weeks at a time. We recently started to use the outdoor commercial refer and freezer too. My son got out of the Navy and is home while looking for a job so our food bill DOUBLED over what my wife and I eat LOL!
