Roof Top High Efficiency Furnace Venting Options

These pvc pipes are connected to the furnace and expelled outside.

Roof top high efficiency furnace venting options.

Example of high efficiency furnace venting on a roof. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof. This high efficiency venting system must be installed when you install the new furnace. Explaining the difference of exhaust venting in a high efficiency furnace versus a standard efficien.

Sidewall power vents also rate highly in efficiency and safety. Types of high efficiency furnace venting systems there are two types of condensing furnaces. Another problem is that flue pipes that go through the roof tend to be less efficient. Sidewall vent systems are especially great for replacing old chimneys and it is one of the more affordable options to consider when installing a venting system for your gas furnace.

The two pipe system is most common in home heating applications. High efficiency furnaces take advantage of the heat in the combustion gases that are wasted in natural ventilation systems.

When the vent is withdrawing air from the house it expels the gas outside through the vent. That depends on whether you have a standard efficiency or a high efficiency furnace. Also known as the type b this vent is operating on the natural air convection. In a great majority of cases plastic piping is used to vent high efficiency equipment.

Two pipe or direct vent systems and single pipe systems which have non direct venting. It is classified as type bh venting. So which type of venting system should your furnace have. The fan works in conjunction with the furnace usually turning on before the furnace starts.

Due to the condensing nature of a high efficiency furnace its venting must be made of a material that is resistant to corrosion.
