What's in your baseload?

Oscargrouch

Have done the test on base load figures taken from Wattson/Holmes....many may dispute the accuracy, but I think, it is better than most..
Here goes:-
Figures were compiled from Data over seven days 6th - 12 Nov '13. (incl) Base usage worked out at 0.2096428 kWh per hour over a 4 hr averaged period. (00.45 - 3.45) I was going to check it against the CU meter but could not persuade TBH to get up at 03.45 - go outside to do the second reading with all the lights off......(she is not a Watts Anorak person):rotfl:

Couldn't you buy her a torch ?

Hiya Oscar, not being pedantic, but unless you did this when the clocks went back, that's a 3 hour interval?

Did you take the consumption (Wh) between the two periods and divide by time (3hrs), or do you mean you recorded the import (W) at each time hourly (4 periods, covering 3 hours) then added the 4 and divided by 4?

Maybe I'm just confusing myself?

This is a result from my Flashcounter :-

StartTime 2013-11-13 01:31:55
StartSecs 5515
StartFlashes 7490
FinishTime 2013-11-13 03:30:06
FinishSecs 12606
FinishFlashes 8200
FlashesInPeriod: 710
Timediff 7091 seconds
Calc Wattage = 360

For those two hours, there were no E7 appliances set up to run (I was hoping for a good generation day today) and heating will have been just about shut down.

I'll look at some similar periods later.

Yes Mart, added the four/four hence the long number = 200 kwh base with the usual stuff on........:rotfl:

Never done it particularly accurately, but recording meter reading last thing at night, and first thing in morning, repeatedly (about 2 years ago) showed baseload around 150W. Would have included short amount of CFL lighting, but only 8W or so, and some TV, but again, not too long, and also meter with no decimal places ........ but hopefully in the right ball park.

Thinking about it, I could just move the sensor from one of my Optismart's over to the import meter, then connect the ENViR up to the computer .... perhaps if I get bored!

This is what the Bar Graphs looked like; curser over each one to see the figures, close enough for me.



It also bears out my estimation, as when I have a cuppa in the morning, Wattson, set on usage mode sits at 190 - 210 Watts; jumps up a few when fridge freezer switches on in the kitchen and then back. Havent checked the garage at these time to see what the two in there are doing.....
