The Bard 8604-164BX is an OEM electric heat strip kit rated 5 kW at 240 volts, used as supplemental or emergency heat in compatible Bard wall-mount HVAC units when heat pump output is not enough or during defrost. This heater assembly is built to Bard specifications to fit the correct heater compartment and connect properly to the factory wiring so your system can stage heat reliably and maintain comfort in colder conditions. Because heat strip options vary by kilowatt rating, voltage, and terminal configuration, verify the unit model and the required heater kit part number in the Bard parts list or service manual before ordering to ensure proper fit and safe operation.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
