I have a Paragon electric kiln. On low, it draws 22.9 amps. On medium
it draws 43.8 amps. On high it draws 44.4 amps. Does anyone know how
to convert this to kilowatt hours so I can figure out how much my
firings cost? Here is my firing schedule:
Low = 2 hours
Medium = 2 hours
High = 6 hours
Lisa,
Watts is equal to Amps times Volts............or W= A x V. A Kilowatt
is 1000 Watts. Kilowatt Hours is Watts times the time (running at that
amount of Watts) divided by 1000..................or (Watts x Time)/
1000.
Without the voltage the kiln runs at you can't do the calculation. This
should be on the kiln or your electrician will know. Likely it is 220 or
240 Volts. Could be something else like 208 or whatever. If you just use
220 you are probably close enough for government work .
So you get 2 hours times (Amperage on low [29.9] x Voltage) / 1000.....plus
2 hours times (Amperage on medium [43.8] x Voltage) / 1000.......plus 6
hours times (Amperage on high [44.4] x Voltage) / 1000. Add it all
together and you get total Kilowatt Hours to fire.
Multiply by your cost per Kilowatt Hour (on your electric bill).... and you
have the cost to fire the kiln (within a reasonable margin of error).
BTW... are you sure about that medium and high Amperage figure? Seems too
close in draw.
BEst,
