Gree FLEXA2LHTR12KW 12kW Electric Resistance Auxiliary Heater Kit for FLEXX Ultra R32 (FXU Series) Central Air Handlers – 208/240V, 1-Phase, 60Hz
<p><span style="color: rgb(0, 0, 0);">A factory-engineered, field-installed electric resistance backup heat kit designed exclusively for integration into Gree's FLEXX Ultra R32 inverter heat pump platform (FXU series ducted air handlers). This 12-kilowatt heater module slides into the air handler's dedicated electric heat cavity to deliver supplemental and emergency-mode heating capacity when ambient outdoor conditions drive the inverter heat pump beyond its balance point, ensuring uninterrupted indoor comfort during deep cold spells and defrost cycles. The assembly is built around nichrome resistance heating elements paired with high-limit thermal cutout protection and a sequenced contactor system that staggers element energization to manage inrush current and reduce stress on the home's electrical service. Engineered as a true OEM-matched accessory, the kit is wired directly into the FXU air handler's onboard 24VAC control logic, allowing the inverter heat pump's main control board to call for, modulate, and stage auxiliary heat automatically without external thermostat reconfiguration. Compatible with the FXU36, FXU48, and FXU60 indoor units (3-, 4-, and 5-ton FLEXX Ultra R32 air handlers), the FLEXA2LHTR12KW is the highest-output heater kit in the FLEXA2L family, making it the preferred choice for cold-climate installations, larger conditioned envelopes, and installations where the heat pump must be supplemented during peak winter demand. The unit ships ready for field installation by a qualified HVAC technician with the cover plate and integrated breaker hardware required for safe, code-compliant integration.</span></p>

| value | rgb(0, 0, 0);">Electric resistance auxiliary heater kit rated at 12 kW nominal output, designed exclusively for installation inside the Gree FLEXX Ultra R32 (FXU series) central air handler. Operates on a 208/240V, 1-Phase, 60 Hz dedicated power circuit, with rated output of 12 kW at 240V and a proportionally lower output of approximately 9 kW at 208V (per Gree's standard FLEXX heater output curve). Manufacturer SKU: FLEXA2LHTR12KW. Compatible exclusively with the Gree FLEXX Ultra R32 FXU air handler line — confirmed compatibility with FXU36HP230V1R32AH (3-ton), FXU48HP230V1R32AH (4-ton), and FXU60HP230V1R32AH (5-ton) indoor units; not for use with the legacy FLEXX (R410A) FLEXX24/36/60HP series, which require the FLEXXHTR-series heater kits instead. Kit includes the resistance element assembly, mounting hardware, integrated factory contactor/relay assembly with staged element sequencing, high-temperature thermal limit cutout for over-temperature protection, cover plate, and integrated circuit breaker for code-compliant overcurrent protection. Wiring integrates with the air handler's onboard 24VAC control circuit, allowing the FLEXX Ultra inverter control logic to stage auxiliary heat automatically based on call-for-heat demand and outdoor balance-point conditions. Power wiring must be sized per applicable national and local electrical codes; the heater kit requires its own dedicated branch circuit separate from the indoor unit's primary power feed. Part of the FLEXA2L heater kit family which also includes the 6 kW FLEXA2LHTR06KW, 9 kW FLEXA2LHTR09KW, and 15 kW FLEXA2LHTR15KW variants, allowing installers to size the auxiliary heat output to the building load and electrical service capacity. Refrigerant compatibility: designed for FLEXX Ultra R32-refrigerant air handlers only. Installation must be performed by a qualified HVAC technician with all power to the system disconnected at the main electrical panel prior to opening the air handler.</span></p> |
