True or False: Ducts can be attached to a wall furnace.

The assertion that ducts can be attached to a wall furnace is generally false. Wall furnaces are designed to be standalone heating units that primarily rely on radiant heat and convection to warm the surrounding space. They typically operate using natural or propane gas and are engineered to serve as a direct heating source in a specific area without the complexity of ductwork.

When ducts are used, there could be significant concerns regarding airflow, efficiency, and safety. Wall furnaces are not manufactured to have ducting systems integrated into their design, as this can lead to improper air distribution, reduced efficiency, and potential safety hazards. Additionally, wall furnaces are not meant for central heating; they serve localized heating needs, which further reinforces the idea that duct attachment is inappropriate.

In certain installations, heaters specifically designed for ducted systems are available; however, traditional wall furnaces do not accommodate ductwork in their typical usage scenarios, maintaining the standpoint that ducts should not be attached to a wall furnace.
