What is the difference between stove pipe and chimney pipe?

Stove pipe and Chimney pipe are both vent pipes for heating appliances. Normally Stove pipe usually refers to black pipe that can be single wall or double wall. Normally stove pipe is only allowed to be used from the top of certain heating appliance to where the pipe will go through a wall or ceiling. Chimney pipe usually has a shiny steel finish and is used once the venting goes through a wall or ceiling and must be used from that point through the end of the run that exits the home. In most cases chimney pipe is referred to as Class A pipe, which means it has a great safety rating.

The most important thing, is to check the manual for your heating appliance as it will outline what kind of venting is required.

The reason that some people choose to use single wall stove pipe is because it allows more heat to radiate into the room, because the walls of the pipe are not usually insulated. This helps when the appliance is a main source of heat for a room.
