To install a baseboard heater, you will need to turn off the electricity at the fuse box, make sure the electrical supply wires are the same voltage as the heater and determine a safe area for the heater. All of the materials should comply with the National Electric Code.
The tools you will need are a Phillips and flat head screwdriver, wire strippers, wood screws, a drill and drill bit, wire connectors and a strain relief connector. A baseboard heater can be installed on any floor surface, including carpet, as long as it does not block the lower air intake located one inch from the bottom of the unit. Do not install the heater below an electrical outlet.
Position the heater by locating the wall studs closest to the electrical supply wires at either end. Make sure the heater is flush against the wall and remove the wiring compartment cover. Remove the slotted knockout closest to the supply wires and install a strain relief connector. Pull the supply wires through the connector and leave six inches of wire leads. Use Phillips screws and mount the heater, attaching it to at least two wall studs, then connect the lead wires to the supply wires using connectors to finish installation.
