Lennox ECB48 Electric Heat Kits
The Lennox ECB48 Electric Heat Kits are ETL listed and designed for easy field installation inside the air handler cabinet. These kits are available in a variety of voltage and kilowatt ratings—refer to the specific Air Handler Tables for model compatibility.
Each kit features helix-wound nichrome heating elements that are directly exposed to the airstream, providing immediate heat transfer, lower operating temperatures, and extended service life. Every element includes a precisely located limit control with a fixed temperature shut-off and automatic reset for added safety. A supplemental thermal cutoff limit offers an extra layer of protection against excessive heat.
Heater control relays are included as standard and operate based on signals from the control board, staging the elements on and off in equal increments with a built-in time delay between activations. The control box and access cover are constructed from heavy-gauge galvanized steel for long-lasting durability. All controls are factory-installed and pre-wired for convenience. Low-voltage connections are plug-in compatible with the air handler for straightforward setup.
Circuit Breaker Models (CB) CB models come equipped with factory-installed circuit breakers that provide protection against overloads and short circuits. These breakers are both current-sensitive and temperature-activated, with manual reset functionality. In many areas, the integrated circuit breakers meet code requirements as a disconnecting means, eliminating the need for a separate field-installed disconnect. Always consult your local electrical codes for proper installation and compliance.

SEER stands for Seasonal Energy Efficiency Ratio. It measures the cooling efficiency of an air conditioner or heat pump over an entire cooling season. Essentially, it tells you how much cooling output (BTUs) you get for every unit of energy (watt-hour) used.
Higher SEER = more efficient
SEER ratings have traditionally been used in the U.S. to compare energy efficiency across systems.
Example: A 14 SEER unit uses less electricity than a 10 SEER unit to produce the same cooling.
What is SEER2?
SEER2 is the updated efficiency rating standard that reflects new federal testing procedures implemented by the Department of Energy (DOE) in 2023. It measures efficiency more accurately by accounting for real-world conditions, including:
Energy usage in modern airflow and installation configurations
More realistic climate and seasonal variations
Changes in the refrigerants and equipment designs
Key difference: SEER2 ratings tend to be slightly lower than SEER ratings for the same unit, but they provide a truer representation of actual efficiency in your home.
Why SEER2 is the new standard
The DOE updated testing to better match how systems perform in real homes, rather than ideal lab conditions.
It encourages manufacturers to improve real-world efficiency, not just test-case efficiency.
For consumers, SEER2 ensures:
Better long-term energy savings
Improved comfort through more accurate performance expectations
Compliance with modern federal efficiency regulations
In short:
SEER = old efficiency measurement (ideal lab conditions)
SEER2 = modern, realistic efficiency standard (real-world performance)
Better quality = SEER2 units are designed and tested to give actual efficiency and savings, not just theoretical numbers.
Understanding EER vs EER2
What is EER?
EER stands for Energy Efficiency Ratio. It measures an air conditioner or heat pump’s efficiency at a single, specific outdoor temperature, usually 95°F.
Higher EER = more efficient at peak conditions.
Unlike SEER, which averages efficiency over a season, EER tells you how the unit performs under hot, steady-state conditions.
Example: A unit with an EER of 12 produces 12 BTUs of cooling for every watt of electricity consumed.
What is EER2?
EER2 is the updated testing standard introduced by the Department of Energy (DOE) to match the same real-world adjustments as SEER2.
Accounts for modern system designs, refrigerants, and installation configurations.
Measures efficiency more realistically under peak operating conditions, rather than just ideal lab setups.
Like SEER2, EER2 numbers are usually slightly lower than traditional EER, but they are a more accurate reflection of actual performance.
Why EER2 is the new standard
Ensures consistency with SEER2 testing methodology.
Reflects true cooling efficiency under extreme heat, where peak performance matters most.
Helps consumers understand real-world energy use and savings potential during the hottest days.
Meets modern federal efficiency regulations and encourages manufacturers to improve performance under actual conditions.
In short:
EER = old standard, measured under lab conditions at 95°F
EER2 = modern standard, measured under realistic, real-world peak conditions
Better quality = EER2 gives you true peak efficiency, not just theoretical performance.
