ACiQ 15 Kilowatt 51,000 BTU Electric Heater Coil | EHK15AKB
Product Overview
The ACiQ 15 Kilowatt (51,000 BTU) Electric Heater Coil (model EHK15AKB) is an electric heat accessory designed to install in compatible ACiQ fan coils and air handlers. It provides reliable supplemental or backup electric heat for heat pump systems or can be used for straight electric heating when paired with a cooling-only condenser and matching equipment.
Key Features:
- Delivers up to 51,000 BTU (15 kW) of electric resistance heat
- Single-phase operation at 208 / 230 / 240 volts
- Factory electric heat accessory for compatible ACiQ fan coils and air handlers
- Internal circuit protection via integrated circuit breakers (model EHK15AKB)
- Can be staged by the installer for multi-stage electric heat when used with appropriate controls
- Lightweight 9 lb design for easier handling during installation
- Carrier equivalent: KFCEH3101C15 for replacement and compatibility cross-reference
- Ideal as auxiliary or emergency heat in heat pump systems, or as primary heat in mild climates
Important
High-voltage electric heater accessories must be installed and wired by a licensed HVAC or electrical professional. All field wiring must conform to local building codes and the latest edition of the National Electrical Code (NEC). The main electrical disconnect must be switched to OFF and properly locked/tagged out before installation, adjustment, or servicing.
Wire size, overcurrent protection, and circuit configuration must be selected based on the electrical data shown on the unit and heater nameplates and in the installation manuals. Always follow the ACiQ EHK and EBAC installation instructions for safe and compliant operation.
Design & Operation
Electric Heat Accessory
The EHK15AKB heater coil mounts directly into the compatible ACiQ fan coil or air handler cabinet. When energized, the electric elements provide resistance heat that is delivered through the existing duct system using the indoor blower. This allows you to add efficient electric heating capacity without replacing the entire air handler or ductwork.
Staged Heating Capability
The 15 kW heater can be configured by the installing contractor for multi-stage operation using the heater’s internal relays and time-delay controls. When properly wired and staged, this allows the system to bring on heat in steps rather than all at once, helping improve comfort and reduce electrical demand spikes.

Installation & Maintenance
Installation of the ACiQ 15 kW heater coil includes mounting the heater assembly in the approved fan coil or air handler, attaching the circuit breaker or fuse assembly (if included), connecting the heater harness to the control board, and bringing field power and ground conductors to the designated lugs or terminal block. Your technician will also verify blower CFM, adjust fan speed taps or ECM settings as needed, and confirm proper staging and operation according to the installation manuals.
All service, wiring changes, and heater staging adjustments should be performed only by qualified personnel familiar with high-voltage electric heat accessories and with the proper tools and test instruments. Periodic inspection of electrical connections and breakers/fuses is recommended to ensure continued safe operation.
