Horizontal unit heaters provide a sweeping effect over outside walls and are sufficient to heat most buildings except those with large central floor areas.

Four-way vertical discharge units are used to heat large central areas and buildings with high ceilings or buildings with large heat loss through the ceiling.

High-velocity vertical unit heaters and door heaters are used to reach hard-to-heat areas or to provide blankets of warm air to large open areas such as loading doors.

Unit Heaters—Typical Arrangements

Many of the best reasons to insist on Armstrong unit heaters are ones you never even see. Components like motors, bearings, tubes, enclosures and fins are heavy-duty, to ensure lasting performance.

Armstrong’s options for fin material, pitch, height and type, for example, help explain why our heating cores last much longer and perform with greater efficiency than competitive units. These factors all have a bearing on heat transfer. Knowing how to balance these and other factors is the key to a cost-effective solution. That knowledge is perhaps the most important of Armstrong’s many hidden benefits.
