description

The Lennox ECBA25-20CB Electric Heat Kit acts as the high-capacity "heating brain" for your air handler, providing critical supplemental or primary heat during extreme cold or heat pump defrost cycles. This 20 kW assembly is engineered specifically for Lennox CBA25UHV and CBA27UHE air handler series, featuring integrated sequencing to stagger the activation of heating elements. This staggered approach prevents massive voltage spikes and ensures a steady, comfortable rise in discharge air temperature, maintaining the efficiency and safety of your entire HVAC system. 

Key Features

  • Precision OEM Part Number: A direct factory-authorized match for ECBA25-20CB (Cat # 16Y46), ensuring the internal dimensions and plug-and-play wiring harnesses align perfectly with Lennox air handlers.
  • Integrated Circuit Breaker: Features a built-in heavy-duty circuit breaker for localized overcurrent protection, allowing for a safer installation and meeting most local building codes for high-wattage appliances.
  • Silent Sequencing Technology: Utilizes high-grade sequencers to quiet the "click" of heating stages, providing a gradual ramp-up of heat that eliminates the expansion noise in ductwork.
  • Nickel-Chromium Elements: Constructed with high-grade Ni-Cr heating coils designed for rapid thermal transfer and resistance to oxidation, ensuring years of reliable emergency heat performance.
  • Thermal Safety Monitoring: Equipped with primary and secondary high-temperature limit switches that automatically cut power if airflow is restricted, preventing the unit from overheating.

🛠️ HVAC Depot Pro Tip

Take a Picture First! Before sliding the new heat kit into the air handler cabinet, photograph the factory jumper bar and the high-voltage terminal block connections. 20 kW kits require significant amperage; ensure your field-supplied wire gauge (typically 4 AWG or 6 AWG depending on local code and run length) is rated for the total load. Diagnostic Check: After installation, verify that the "Heater" settings on your thermostat or control board are correctly configured. If the sequencers aren't receiving the 24V signal from the 'W' terminal, your elements will never energize, even if the breakers are on.
