This is a little more complicated than a simple number. The average wall outlet is rated at 120v, but due to voltage drop on longer wiring runs, you can expect to get as little as 110v out of an outlet. Since this is a 1500 watt heater, you should expect it to draw between 12.5 and 13.5 amps of current on the high setting. Another thing to note is the voltage will fluctuate throughout the day, I've seen outlets put out as little as 100v at times, this would cause a 15 amp draw, which is the max rating on your standard wall outlet/circuit. You will find 20 amp circuits in your kitchen and in some dedicated outlets for appliances such as window A/C units. As long as you aren't running any other heavy loads on the circuit you have your heater plugged into, you should be fine. If you are consistently tripping your breaker, I would consider installing a dedicated outlet for this heater on a dedicated circuit, rated at 15 or 20 amps to be safe, but under normal circumstances, this should not be necessary. Your electrical code may vary in your area.
