depends how much you use it! its 700 watts at full speed so about the same
electricity as 2 gaming computers .

For every hour that this unit runs NONSTOP, it would cost about 7 cents; since it would typically cycle on and off, it would in effect use somewhat less than that..
Understanding Electric Heaters
As an Engineer I would like to clear up some misconceptions on electric space heaters. I have seen several comments here on which heater will be cheaper and/or more efficient to run.
All electric heaters are 100% efficient – there is no flu or vent to the outside of the house for heat to be wasted. All of the energy that comes into the heater from the power lines is converted to heat. With this understanding, you can see that to heat a given room with an electric heater, all heater models and makes will use exactly the same amount of electricity to heat the space. As such, no one electric heater will be cheaper to use than another – THEY ARE ALL THE SAME COST.
What about different wattages you say? Won’t a 1400W heater cost 2x as much to run as a 700W heater? You need to remember that a W is a unit of measure than means 1 Joule of heat per second. This means that a 700W heater puts out 700 J of heat every second and a 1400W heater puts out 1400 J of heat every second. So a 1400W heater will be twice a hot as a 700W heater. However, your electricity meter records how many Joules are used by your house (1KWH = 3,600,000 Joules) so a 1400W heater uses twice as much electricity as a 700 W heater while it is heating BUT it is twice as hot so the room will heat in half the time. THE RESULT IS BOTH HEATERS USE EXACTLY THE SAME AMOUNT OF ELECTRICITY TO HEAT THE SAME ROOM.
Based on the above, the choice of heater you make should not be based on how much it will cost to run but on the features and the operational mode. Some heaters are slow to heat a room but hold the heat well once they are warm (like oil filled), others are fast to heat a space but are noisy (like ceramic fan heaters). The heater wattage is important to consider in that you need a unit that is capable to producing enough heat to warm the space. A larger space will need a larger wattage heater. You also have to consider how much power remains available on the circuit you plan to plug the heater into. A 1500W heater will almost max out a single circuit in a typical house so do not expect to plug a 1500 W heater into the same circuit as your computer or TV! So choose your heater based on the features, style and safety you need, not based on an expectation that one will be cheaper to use than another.

it's actually a 400W heater not 700W as advertised (went to the store).
price of electricity today in halifax is about 1KWH = 11 cents.
That means if you run a 1000W (1KW)appliance for an hour (hence 1KWH), it will cost you 11 cents.
so running the 400W heater for an hour costs about 5 cents.
As a 700 watt heater it will draw roughly 6 amps (@120 volts) when the room temperature is calling for heat, or the equivalent of 12 x 60 watt bulbs. How often it calls for heat will depend on the outside temperature and the quality of your insulation.
