Wall-mounted electric unit heaters are available in a number of voltage/phase combinations; all are UL-listed. To further enhance heater versatility, as well as minimize system installation and design time, a wide selection of pre-engineered, factory-installed control options is offered.

Offered in 16 models with heating capacities ranging from 5,119 to 16,380 Btu per hour, these electric unit heaters are lightweight and compact—all units weigh less than 30 pounds, and the grille-and-frame assembly measures approximately 21 inches high, 16 inches wide and 5 inches deep (including the rough-in-box).

To assure quiet operation, the heater design incorporates a "paddle-wheel" style vaneaxial blower that delivers 175 cfm of heated air in a downflow discharge pattern. The fan is driven by a low-speed (600 rpm), four-pole motor, and is controlled by a tamperproof, built-in thermostat calibrated for an operating range of 55°F to 85°F.

For durability, the heater grille consists of individual louvers reinforced by 0.09-inch vertical steel bars; all unit housings are constructed of 20-gauge steel. Both grille and heater box are painted with a rust-resistant, black baked enamel finish that complements any decor. A snap-on, anodized aluminum frame accents the grille and is secured to the heater with an inconspicuous fastener.
