Appliance Output per Hour

Hi there- I'm hoping someone can help me. I'm thinking of purchasing a space heater with the following ratings

Amps - 12.6 Watts - 1500

I'm trying to find out the kw/hr it puts out. I'm assuming the kw are

1.5? When an appliance lists watts is it watts per hour? I'm not sure how I get that watts or kw/hr. Bottom line I'm trying to obtain an estimated cost per month of running this appliance 3 hrs/day, 7 days/week. If someone can help me understand how to get to the kw/hr I'd really appreciate it!

1500 watts is 1.5 kw. So every hour it uses 1.5 kwh (that's dimensionally kwh, kilowatts * hours, not kw/hr). If electricity costs you 10 cents per kwh, the heater will cost 15 cents per hour to run.

Check your electric bill to see your local cost per kwh.

Newspapers commonly refer to energy in kw/hr, because they all graduated from journalism school.

They don't graduate, they run out of money. Then the school gives them a diploma to free up the seat for another paying customer.

Yes. \'kilo\' means "times 1000", so 1.5 kilowatts = 1.5kw * 1000 =
1500 watts.

Thank you! No more "/" in kwh. I did not graduate from journalism school. :^)

Does this heater have a thermostat? If it does, it could cost a bit less since it may not actually be running all the time. Depends how cold it is and how well insulated the room is.

PS if you really want to look like you know what you are talking about, it should be a capital W in kWh because watts are named after a person (James Watt)

Sorry, but I don't care how I look.

The watt or kilowatt is a measure of energy at an instant of time. Watt seconds, or joules, or kilowatt hours are a measure of power or work. You pay for power, not for energy. There is no such unit as kilowatts per hour!

Get yourself a copy of "Dictionary of Quantities and Units" by J B Drazil (Pub = Leonard Hill, ISBN = 0 24944092). It is invaluable for this sort of problem.

You can't measure energy at an instant in time. Well, maybe potential energy. Energy is a time integral.

Joules or kwh are measures of energy, not power. And you pay for energy, not for power.

Kilowatts per hour is a legitimate engineering unit, but it's not energy.

you've got work and power swapped round.

It's only called a "power bill" colloquially,

John,

I meant that for the OP's information. I wasn't intending to criticise your post, and I'm sorry if I gave that impression.

I know that you know what you are talking about.
