On-Wall or In-Wall? Which do I need?
Tips for deciding which linear fireplace option is best.
You can install an On-wall fireplace just about anywhere, as long as there is enough support behind the wall. You will also need to be close enough to an electrical outlet to plug in the fireplace. Note that most fireplace cords are about 72” long, and should not be connected to an extension cord.
You can install an In-Wall fireplace if you are building a new wall or a new cabinet, and you can make space for the fireplace to fit into this new structure. Note that you will need to have electrical inside the wall or cabinet.
You can also install an In-Wall fireplace if you are able to cut into an existing wall and frame an opening for the fireplace to fit into. Note: this is not advisable on an exterior wall of your home, as it would require you to break the building envelope and remove insulation. It is also not usually possible in a condo wall.
