Can I Install My Heater Under a Window Or By a Door?

When installing your heater, it is recommended that you install it on an inside of a wall. If you are installing your heater by a door or window, make sure:

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

How Should I Mount My Baseboard Heater?

Baseboard heaters must be mounted horizontally-- near or at floor level only. For baseboard heaters, allow 12 inches of clearance in front of the heater and 6 inches to the side and above.

Can I Use an ON/OFF Electrical Receptacle to Control My Baseboard Heater?

NO—We recommend using a thermostat to control your heater. A line voltage thermostat is typically used with single-room heaters, such as electric wall heaters, or electric baseboard heaters. Low voltage thermostats are typically used to control heating and cooling systems, and are generally more common than line voltage thermostats. 

Only use a low voltage thermostat with a Baseboard Heater if:

  • The amperage load exceeds the rating of the line voltage thermostat.
  • It is combined with a relay.
