Airflow Furnace In Attic

The trick to the installation of a gas furnace in an attic space is routing the condensate drain from the attic down through the core of the house to the basement.

Airflow furnace in attic.

Attic furnaces take advantage of the closer proximity to use shorter lengths of air duct. High efficiency furnaces aren t usually recommended for an attic. A downflow system is usually used when there is no basement or. This drain removes the excess water that a heating system will generate.

A furnace can suffer from a drop in energy efficiency if it s in an unconditioned space such as an attic. That means you have higher energy costs and less efficiency since you re blowing the air down instead of allowing it to rise naturally. The total drop in efficiency can be up to 35. The arrow should always point towards the return.

The first and possibly most important thing is to make a commitment to yourself to change your hvac filters regularly. It will not require long lengths of pipe to deliver heat to the rooms as a basement furnace does. Here s an easy way to figure out which way the air flow arrow goes. But sometimes you may not know which way the air is flowing.

The arrow should always point in the direction the air is flowing. Having your hvac system in your attic isn t dire though you ll need to do some work to keep your air conditioner or furnace system running as efficiently as possible. An attic furnace is closer to the upper stories of a multi level home. This refers to configuring a furnace to discharge warm air from the right side in a horizontal right furnace or the left side in a horizontal left furnace.

Air ducts lose a fair amount of heat through leakage so shorter lengths are more efficient. When changing furnace filters many people wonder where the arrow of the filter should point towards. Most of the issues that furnace might experience in an attic are due to extremely cold weather in this poorly insulated space. The drain must be installed through the core of the house as water will be flowing during the colder months.
