Gas Furnace In Attic

More recently builders and insulation contractors have been foaming attics and roof spaces creating a fully sealed and insulated attic space that works differently than an old school ventilated attic space where only the floors are insulated.

Gas furnace in attic.

A furnace can suffer from a drop in energy efficiency if it s in an unconditioned space such as an attic. When you can use natural gas over electricity there is an opportunity to boost the efficiency rate of your furnace as well. The rods need to be of sufficient length to allow for proper clearances from combustible materials. A gas fired furnace installed in this type of attic is no issue.

Whatever the reason you have questioning the placement of a furnace in an attic is a good idea. Using natural gas the furnace transfers heat energy to the air through the heat exchanger. The horizontal furnace may also be suspended from the joists using 3 8 all thread rods with pieces of angle iron underneath the furnace to form a hanging rack at both ends and the midpoint. Most of the issues that furnace might experience in an attic are due to extremely cold weather in this poorly insulated space.

Why in the discussion of attic retrofits amp. Gas furnaces does the conversation always focus on the combustion air the furnace needs to operate and never seem to hear about the safety side of it. Today that s not as true as it s become more evident that there are some real and significant drawbacks to putting a furnace in an attic. In an electric furnace the air is pushed past heating elements but the principle is the same.

A furnace in the attic is a design that works for all homes. The scary fact is that you have a unit that is emitting carbon monoxide and yet there is no concern about the safety of the building occupant. This drain removes the excess water that a heating system will generate. If a high efficiency unit can hit 90 with a typical installation then you can achieve a rating of at least 65 with a standard installation.

The chance of a gas leak in the attic would be slim. The drain must be installed through the core of the house as water will be flowing during the colder months. High efficiency furnaces aren t usually recommended for an attic. The blower fan unit then pushes this heated air through the air ducts of your home.

The combustion chamber will also be vented to the exterior so not much chance of a carbon monoxide problem either.
