Before Installing A Vent Damper On Your Furnace

A vent damper is a great way to improve the energy efficiency of a furnace. It works by closing off the flue immediately after the burners have ceased to fire, thus preventing heat from escaping up the flue. This allows the heat exchanger more time to absorb that heat. Yet a vent damper isn’t always the best solution to an inefficient furnace. This article will discuss two things you should know before hiring heating installation in Atlanta GA to add a vent damper to your furnace.

A vent damper can only be used on one appliance. 

In many cases, furnaces share their exhaust flue with other appliances such as water heaters and boilers. In that case, it is not safe to install a vent damper in the shared portion of the vent. Instead, the vent damper must be located inside of the furnace’s dedicated flue--in other words, before the attachment point of the second appliance.
