How to calculate the cost of a 1000 watt ,electric heather if it is on for an hour?

Question

I am looking for the formula

Answer 1

look on you electric statement it tells you how much per unit

i think it used to be about 12p

but not sure with todays charges.

Answer 2

1000w heater is 1KW heater. It will use that muchelectricity in 1 hour - 1KW.

Conveniently for your question, a unit of electricity that you get charged for is also 1KW! So every full hour you have the heater on and producing heat, you use 1 unit of electricity (It could be on and using a thermostat to turn on and off the heating element).

If you look on your electricity bill it will tell you how much a unit of electricity cost (though there might be 2 rates quoted on the bill). Currently for domestic customers its about 9 or 10p a unit and thats how much the heater costs to run each hour

Answer 3

Electricity is billed by utility companies by Kilowatt-hour.  basically watts times time.  1000 Watts is one kilowatt.  So over one hour, the 1000 watt heater uses one kilowatt-hour if running at full capacity.  A general estimate for rates is about 10 cents per kWh.

Answer 4

First you have to go to Scotland , we do not have electric heather in England !!!

Answer 5

You will consume one kilowatt-hour of energy.  The cost of that energy may vary quite widely depending on location.  It costs approximately  $0.11 from my electric utility, but the actual cost is calculated every two weeks based on the price the utility has to pay for its fuel.  Six hundred kilometers north of me, people pay approximately $0.05 per kilowatt-hour.  The actual cost of the energy then is dependent on a number of factors including the cost of fuel, taxes, local regulations, and so forth.

Answer 6

*Kilowatt (kW): 1000 watts.

Kilowatt-hour (kWh): One thousand watts acting over a period of 1 hour.

The kWh is a unit of energy. 1 kWh=3600 kJ.

*Kilowatt-hour (kWh) is one unit.

your electricity bill will be charged on per unit basis.

There are slabs of units , I mean 1st 100 unit ,next 100  units and so on....and charges will be different.

So, cost of one Kilowatt-hour (kWh)

=1 Kilowatt-hour (kWh) x cost of 1 Kilowatt-hour (kWh)

=1 Kilowatt-hour (kWh) x cost of one unit.

[power=voltage x ampere

One ampere of current flowing at a potential of one volt produces one watt of power.

-The kilowatt-hour (kWh) is not a unit of power. It is a unit of energy. Here's why:

The kW is a unit of power. It is 1000 W or 1000 J/s.

By definition:

power = energy / time

Energy = power × time

If we choose to measure power in kW and time in hours, we have:

Energy (kWh) = power (kW) × time (h) ]

*Each unit of electricity costs £0.08

Answer 7

1000watt = 1kw (kilo watts)

watts are watts / hour

therefore if 1kwhr = 30pence ~
