Cost of electricity is much less then most expect. If the label on
your kiln doesn't specify the wattage of your kiln, you can calculate
it by multiplying the amperage X the voltage. Then check your power
bill for the price per kilowatt hour you're being charged. Multiply
that price X the wattage X 4 hours (that's the average amount of time
your kiln is actually consuming power for a full fuse firing).

As usual, Brady, in your rush to look important you offer more WRONG
information.

Definition: A kilowatt hour (KWH) is 1000 watts of current flowing for
one hour. (Kilo=1,000) Eh?

Once the wattage of the kiln (or any electrical device, for that matter) is
known, that wattage figure must be DIVIDED BY 1000, "then" multiplied
times the hours (or fractional hours) of use and "then" times the KWH price
rate to determine cost of operation. It's grade school math, you dummy.

I know you aren't too smart, so read slowly and look at these examples,
maybe you'll get a clue:

An 1800 watt hair dryer used for 15 minutes at $0.10/KWH is (1800/1000)x
(15/60)x $0.10/KWH =$0.045 cost or less than a nickel to dry your hair.

Running a 150w power supply on a PC left on for 24 hours would be:
(150/1000) x 24 x $0.10/KWH = $0.36 per day.

My electric bill came today. We used 1079 KWH in a 31 day billing cycle and
the bill was 75.90 plus taxes. That's about $0.07/KWH, so my examples above
are off a few pennies.

A 40A/220v kiln is 8800watts, or 8.8KWH if it runs for an entire hour. On a
hypothetical cycle of 4 hours, that is 35.2KWH or about $2.46 at my local
electric rates.

Once again, the Canadian prairie dog pops out of his hole, barks a bit, and
takes a round right between the eyes. When will you ever learn?
