Which Pipe Should I Use When Venting My Furnace, Boiler, or Corn Appliance?
High efficiency appliances such as furnaces and boilers are a great way to cut down on your heating bills. The more efficient an appliance is the less fuel that is being used. Every appliance is given an efficiency rating. The efficiency rating is referred to as the amount of fuel that is being directly used to heat the home. High efficiency is obtained when heat from the flue is extracted before it is vented into the atmosphere. To classify an appliance as highly efficient, the efficiency rating is going to be 86% or higher.
