Whether you have a few questions during installation or are doing pre-purchase research, the video above will show you the basics of how to install a wall heater with a built-in thermostat. This video features our Com-Pak heater but the process will be almost identical for any wall heater with a built-in thermostat. Just be sure to check your Owner's Guide for your specific heater's cutout size and clearance requirements. If you're looking to install a wall heater with a wall thermostat, we have a video for that too. The installation isn't too complicated, but if you're uncomfortable at all with working with electricity, this isn't the project for you. Please consult the help of a licensed electrician.
