Question: how much does it cost to run a 1500w oil heater?
Answer: To calculate the cost of operating a 1500 watt infrared heater will require the electricity cost of your residential area. If yours is 10 cents per kilowatt-hour, that's 15 cents per hour. If you run your space heater for 10 hours in a day, that's $1.5 daily which works out to be $67.5 a month.
