How to Add Baseboard Heater Fins


When you have a baseboard heater installed in your home, the unit includes small aluminum parts called fins that are attached to the heater pipe and help to increase heat output. Often the fins on the heater pipe should be cleaned to remove dust, but you can also manually remove a heater fin if it is cracked or broken. You can also add more heater fins at any time to increase the heater's output. New heater fin parts can be ordered from your baseboard heater manufacturer or an online retailer.

Things You'll Need

  • Phillips screwdriver
  • Turn off the electrical power to your baseboard heater from your home circuit breaker.

  • Remove the screws from the left side cover of the baseboard heater using a Phillips screwdriver, then remove the cover.

  • Pull up on the end of the copper pipe, then slide the square aluminum fin part off of the pipe, if you have one that you need to replace.

  • Insert a new fin onto the end of the pipe, and push it all the way back onto the pipe so that it's in the same position as the fin you replaced.

  • Reconnect the copper pipe, and place the heater cover back on. Reinsert the screws into the cover.

  • Turn the electrical power back on from the circuit breaker.
