costs to run?

Question

how much does a 70 watt 240 volts water cooler cost an hr to run

Answer 1

The amount of electricity listed on the label is the maximum amount that the appliance will ever use. For example, a 70-watt cooler will only run at 70 watts when the compressor's running (which is when it makes that humming sound, indicating that it's actually chilling the water). Most of the time it probably just sits there, using only 5 watts or so for its electronics.

To measure how much electricity something uses for a certain period of time (like a week or a month), you can use a watt-meter.

Anyway, your power company probably charges by the kilowatt hour. In the US, the national average is 9.8 cents/kwhr, but judging by the fact that your device runs on 240 volts, I would guess you are not in the United States. the calculation is the same, whatever your rate is. A kilowatt is 1000 wats. so your 70 watt devices will be billed 70/1000 X 9.8 = .686 cents per hour at full load.

Answer 2

The tension is not used to determine the cost, only the power.

As they said, the eletricity co. charge us in $/kWh

Example: 1 kWh cost $ 0,10

then - your water cooler costs

in ONE HOUR
70 Watts / 1000 (kW/W) * $ 0,10 = $ 0,007

in 720 hours (ON all the time for one month)
$ 5,04

Answer 3

Electric companies charge electricity by kilowatt-hours. Typical rate now is about 15 cents for residential customers. You do the math.

Answer 4

This depends on the cost per watt charged by your utility.
