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.
