If a heater delivers 1500 watts at 110 volts how much the electricity bill will be a month if it is on all the time I leave in Chicago?

Answer 1

Electricity is nearly always sold in kilowatt-hours (kW h). It is important to note that this is not a measure of kilowatts per hour (kW/h) but the product of kilowatts and hours.

1500 watts is 1.5 kilowatts. Assuming a month containing 31 days, with 24 hours per day the month would contain 744 hours. The heater uses 1.5 kW when operating, so multiplying the two gives the result that your heater is using 1116 kW h per month if it is left running all the time.

Without knowing the price of a kW h in Chigaco I cannot answer further. However in Maine I pay on average about $0.16 per kW h in my market. So for me to run your heater non stop for a month it would cost me $178.56.

To find this result for yourself, determine how much you pay per kW h and multiply that number by 1116 kW h.
