You are watching: How many amps does a 1000 watt heater draw?
The over circuit sizing is based upon 75C wire and also for referral only. Always consult regional codes for suitable sizing.According to the National electrical Code heating circuits are thought about a consistent load and also therefore have to be derated by 25%. (For example: a 20 Amp heater circuit can not have more than 16 Amps of pack connected.)120 Volt heaters require 1-Pole circuit breakers; 240 Volt heaters need 2-Pole breakers.Use 2-wire cable through ground (Romex™ or BX).When place multiple heaters ~ above a circuit perform not exceed the wattage provided for the corresponding wire and circuit breaker size. (For example: 2-1000W & 1-1500W, 240V heaters = 3500 watt total. This 3 heaters would call for 12/2 wire and also a 20 Amp 2-Pole breaker if they were to every be placed on the exact same circuit. If much more heaters are required either run a new circuit or increase the wire and also breaker size to accommodate the load.)A 1500 Watt heater will cost the same to operation whether the is 120 or 240 Volt. 240 Volt heating circuits are an ext common because it reduce the Amp draw on her breaker/fuse panel, as the graph shows, you deserve to place an ext heaters ~ above a 20 Amp 240 Volt circuit (maximum of 3840 Watts) matches a 120 Volt circuit (maximum of 1920 Watts).120 and also 240 Volt heaters are not interchangeable. A 240 Volt heater operation at 120 Volt will develop 25% that the rated wattage. A 120 Volt heater operation at 240 Volt will certainly be 4x 120 Volt rated wattage ruining the heater destroyed and also poses a major fire hazard.What voltage room my heaters?
Fan Heater or Baseboard?
Comfort: A fan-forced heater will warm a room within a couple of minutes whereas a baseboard will require 30 to 40 minutes. A fan-forced heater will also maintain a more even temperature due to the fact that the fan will circulate air roughly the room. This to reduce the severity that hot/cold temperature swings.
Efficiency: A 1500 Watt baseboard uses the exact same amount of electric power together a 1500 Watt pan heater. The difference is a fan heater gives more even warmth throughout the room in order to reducing waiting stratification (hot wait rising and not mixing with the cooler floor air). This process makes you feel cooler bring about you to turn the baseboard thermostat to a greater temperature setting whereby that runs more often therefore using more electric power than the same size pan heater.

Every 1° a thermostat is rotate up will certainly raise a strength bill 3.1%. Together such, a baseboard set to 75°F will price you 15.5% much more than a pan heater set to 70°F.
