We recommend that you install your heater on an inside wall, however, you can install it under a window or by a door, just be sure the door does not swing in front of the heater path.

If you do install an electric heater on an outside wall, make sure:

  • The heater is not blocked by drapes
  • There is no electrical receptacle above or below the heater
  • Airflow is not blocked by anything, such as an open door

That really depends on your comfort level and experience with electrical work. To help you decide whether you can tackle a project like this, read through the owner’s guide for your product. Simply visit the product page on our website and download the guide. If you need to install a new circuit or need additional wiring information, our recommendation is to consult a qualified electrician.

If you want to install a heater yourself, make sure you’re complying with the National Electric Code (NEC), the Occupational Safety and Health Act (OSHA), and all state and local codes

Use screws to secure the baseboard heater to the studs in your wall by using the pre-punched “stars” at 1 inch intervals on the back of the heater. See the Owner’s Guide for detailed information on installing your baseboard heater or watch this video.

No—the best way to control your baseboard heater is with a thermostat

You must use a voltmeter. Please note: Testing with a voltmeter requires the circuit panel or fuse box to remain on. If you’re unfamiliar or uncomfortable with electrical wiring, please contact a qualified technician or licensed electrician.

If you have pre-existing wiring, check the voltage of your electrical circuit and install a heater with the same voltage. Both 120 and 240 volt heaters operate with the same output and use the same amount of electricity for any amount of time. 240 volt heaters require double pole breakers, and 120 volt heaters require single pole breakers.

See chart below (per NEC code):

Volts AC

Size of Breaker
or Fuse

Wire Size

Maximum Watts
on Circuit


20 Amp Single Pole

12/2 with Ground



20 Amp Double Pole

12/2 with Ground



30 Amp Double Pole

10/2 with Ground


No, that’s not safe. In fact, please keep furniture, paper, bedding, as well as drapes and curtains away from the heater. Keep safe clearances around your heater so nothing is blocking the flow of air. A good guideline to follow— for baseboards, allow 12 inches of clearance in front of the heater and six inches on the side and above; for fan heaters, allow three feet of clearance in front of the heater and six inches to the sides and above.
