Lennox 19F28 Heater
The Lennox 19F28 is a heavy-duty 15kW electric heat kit designed for seamless integration into Lennox commercial air handlers and packaged units. Engineered for 208/230V three-phase power configurations, this auxiliary electric heater provides reliable supplemental heating or primary heat source functionality in demanding HVACR applications. The open-wire nickel-chromium heating elements are corrosion-resistant and supported by ceramic insulators to ensure thermal stability and rapid heat transfer. This HVAC replacement heater features integrated primary and secondary limit protection to prevent overheating during restricted airflow conditions. For contractors, the plug-and-play wiring harness and pre-punched mounting holes facilitate a precise fit within the blower cabinet, reducing installation time. The heavy-gauge galvanized steel construction ensures rigid mounting and long-term durability against high-velocity airflow. When replacing a Lennox 15kW heater, verifying the MCA (Minimum Circuit Ampacity) and MOP (Maximum Overcurrent Protection) is essential for electrical code compliance.
Technical Performance Features
- 15kW Heating Capacity: Delivers high-output thermal performance for large-scale commercial zones.
- Three-Phase 208/230V Configuration: Optimized for balanced electrical loads in industrial and commercial power grids.
- Integrated Disc-Type Limits: Provides automatic reset thermal protection to safeguard the air handler and ductwork.
- Corrosion-Resistant Elements: High-grade alloy construction prevents oxidation and premature element failure.
- Direct Fit Compatibility: Specifically engineered for Lennox-brand equipment to ensure proper static pressure and CFM alignment.
Common Installation Questions
Is the Lennox 19F28 compatible with single-phase power systems?
No, this specific model is designed exclusively for 208/230V 3-phase electrical services. Using this on a single-phase system will lead to phased imbalance and equipment failure.
Does this heat kit include the necessary circuit breakers?
This unit typically includes the integrated thermal limits and contactors required for operation, but always verify if your specific air handler cabinet requires an additional breaker base kit for local code compliance.
What is the typical application for a 15kW electric heater?
A 15kW electric heater is commonly installed in 3-ton to 5-ton commercial air handlers as emergency heat or to provide a specific temperature rise (Delta T) in cold-climate heat pump applications.
