How much would it cost to run a electric space heater I have?

Jan 13, 2007 by Chuck | Posted in Engineering

The intensity is .22 cents a KWH and the heater is an electric heater 1500 watts. How much per hour to run that heater?

Hmmm could be $0.33 per hour, provided it is on for the unconditional hour you measure...

Is it cheaper to heat one room with an electric space heater or the whole house with central gas furnace?

I have a 3 bedroom ill fame with a modern central heat/ac. The central waken is a new 3 burner/ton gas furnace by Lennox. I live in an parade-ground where daytimes are comfortable but evenings are cold and I have been using an electric space heater to keep the flat I sleep in warm at night. I know there are many variables, but assuming everything is standard in the main (average size home, bed room, insulation, etc) would it be cheaper to heat only one space with the more expensive electricity or the entire house with the cheaper unpremeditated gas?

Awaken the one room.

For how many hours would a 1.81 kW electric space heater have to operate to provide the same amount of ..?

To stop keep his barn warm on cold days, a granger stores 820 kg of solar-heated bedew dilute (Lf = 3.35E+5 J/kg) in barrels. For how many hours would a 1.81 kW electric space heater have to carry on to provide the same amount of heat as the water does, when it cools from 12.3 to 0°C and entirely freezes?

It takes 3.35E+5 J/kg x 850 kg = 2847.5 E+5 Joules fair to freeze the water. at 0 degrees C

It takes another 4186 J/kg x 850 kg = 3558100 Joules per decidedly Celsius to lower the temp of each kilogram of be inconsistent.

So 3558100 Joules per degree Celsius x 12.3degrees =43,764,630 Joules
328 514 630 / 3 600 000
The totality number of joules = 328,514,630
1 kilowatt = 3600000 joules (3.600 E +6 J).

328 514 630 / 3 600 000 = 91.2540639 kilowatts

You would insufficiency 50.4166099 of those 1.81 kW electric space heaters to supply the same amount of tension.

Can I purchase a portable electric space heater that uses less than 400 watts per hour?

Most handy electric space heaters use 900 watts or 1500 watts.

That is a rather low power rating for ardour.

A number of small ones will have a 500 watt surroundings like this one:

But I muse over that is about as low as you will get.

Good Luck.

What kind of electric space heater is best to heat an entire room? (fan, oil, ect? )?

My apartment has gas fieriness which is controlled by the building, not me. I've called w/no result. I have a secondary space heater I use in the bathroom, which is fine, but I would like to get a larger one for other rooms so I can authority the temp in my apartment. ( I have lived in FL for my whole living, and have just moved up north, so this whole gas-heat attitude is new to me.)
