You can hide your wood stove pipe by routing it through the inside of your wall in order to keep it hidden. However, it is not as simple as boring a hole in your wall and routing the pipe up to the roof. You need to insulate it properly first by building a brick wall around it in order to prevent heat from seeping into the wall and damaging your paint or wallpaper. You also have the option of letting it pass through the wall to the outside directly and then leading it up to the roof. It will not be seen from the inside but will be seen from the outside, therefore a proper design is needed so it won’t disrupt the façade of your house.
