Lennox 12S88 Heater
The Lennox 12S88 is a high-performance 20kW electric heat kit designed for field installation in compatible Lennox air handlers and residential units. This HVAC heating element provides robust supplemental or primary heating capacity, delivering up to 68,200 BTUs depending on your specific voltage configuration. Engineered for long-term reliability, the assembly features helix-wound nichrome elements that are exposed directly to the air stream for rapid thermal transfer and reduced element fatigue. This 20kW electric heater includes integrated circuit breaker protection to ensure overcurrent safety and fulfill local disconnect requirements without additional field-supplied hardware.
Designed for professional contractors, the Lennox 12S88 20kW heat kit is a slide-in replacement for the Lennox 89W51 and is compatible with various ECB25 series configurations. It features factory-wired connections for 208/240V single-phase applications, though technicians must verify the HVAC part compatibility and adjust transformer tapping for 208V service to maintain proper relay operation. With an integrated limit control and supplemental thermal cutoff, this unit ensures safe operation even in high-static pressure environments. Ensure your branch circuit wiring and HACR type breaker sizing meet the minimum circuit ampacity (MCA) listed on the equipment nameplate for a code-compliant installation.
Key Benefits- High-Efficiency Heating: 20kW capacity provides consistent thermal output for large-scale residential and light commercial air handlers.
- Integrated Safety: Built-in circuit breakers provide necessary overcurrent protection and serve as a local disconnect point.
- Durable Construction: Heavy-duty nichrome elements resist thermal cycling stress to minimize service intervals.
- Easy Integration: Slide-in design allows for rapid field installation and secure mounting within the unit cabinet.
Is the Lennox 12S88 compatible with my current air handler?
This 20kW kit is specifically designed for Lennox VVC, VRF, and ECB25 series units. Check your internal cabinet clearances and the 9th digit of your unit's model number to confirm electric heat compatibility.
Do I need to change the wiring for a 208V system?
Yes. While factory-wired for 240V, the red lead on the transformer must be moved to the 208V terminal to prevent operational failure or relay chatter in lower voltage applications.
Does this unit include a circuit breaker?
Yes, the 12S88 model comes equipped with factory-mounted circuit breakers, eliminating the need for a separate external disconnect in most jurisdictions.
