# Thread: Electric Meter Running fast

1. @hj

With the heater the amps is per company standard and how do we check amps without heater i.e. load?

2. If you've checked the draw (load) of the heater, and it is within specs, and you said the meter slows way down when it is off...it sounds like it is working exactly like it should. As I said, that's like having nearly 100 100W light bulbs all on at the same time...that's a lot of electricity, and you'll pay for it. Assuming it was on continuously (unlikely, but I suppose possible), that's nearly 10Kw/hr. Where I live, that would cost about \$1.65/hour, \$39.60/day, or \$1188/month.

3. In Saudia Arabia, you should use the sun to preheat your water, then a 3 or 4 KW heater element on very rarely should suffice.

You can always determine the usage by;

The amount of energy represented by one revolution of the disc is denoted by the symbol Kh which is given in units of watt-hours per revolution. The value 7.2 is commonly seen. Using the value of Kh, one can determine their power consumption at any given time by timing the disc with a stopwatch. If the time in seconds taken by the disc to complete one revolution is t, then the power in watts is P = 3600 * Kh Divided by t in seconds. For example, if Kh = 7.2, as above, and one revolution took place in 14.4 seconds, the power is 1800 watts. This method can be used to determine the power consumption of household devices by switching them on one by one.
Well DonL,

Can u please tell me how to measure Kh i.e. watts hours per revolution, as u have mentioned that it is commonly seen as 7.2. Please help.

6. In the U.S.A our meters use the Kh = 7.2, I am not sure what You use in your country.

Whatever your meter uses it will say on the meter, next to the spinning disk, Just put that number into the formula.

Have a good day.

I agree, But one would have to be Imported. lol

10. Plenty of fat girls under those big white sheets.
