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.
Square Foot Space

How much heat do I need for a room?

First determine the square feet by multiplying room width by room length.

Heater Wattage

I have a Lot of windows or my square footage is not listed…

If your square footage is not listed in the chart, or you plan on installing a lot of windows, it is suggested that you choose the next highest wattage. Find the square footage that closely matches yours, and go up to the next highest in wattage.

I have a newer building or live in a warmer climate...

If you are looking to install heaters to a new building, or you live in a warmer climate, it is suggested that you choose the next lowest wattage. Find the square footage that closely matches yours, and go down to the next lowest in wattage.
