What our Experts Think

• Powerful auxiliary heating when temperatures drop
  The Mitsubishi EH17‑MPAS‑L Electric Heater Module provides up to 17.5 kW of electric heat (13.2 kW at 208V), delivering strong supplemental heating when a heat pump alone cannot maintain indoor comfort in very cold weather.

• Two-stage heating for balanced performance
  The module operates with two heating stages (≈8.75 kW + 8.75 kW), allowing the system to increase heat output gradually and maintain stable indoor temperatures without unnecessary energy spikes.

• Designed for Mitsubishi multi-position air handlers
  Engineered specifically for PVA-series multi-position air handlers, the heater integrates seamlessly with compatible Mitsubishi ducted systems used in residential and light-commercial installations.

• Direct-mount installation for cleaner system design
  The heater module mounts directly to the air outlet connection of the air handler, simplifying installation and maintaining proper airflow through the duct system.

• Reliable backup heat for cold climates
  Electric heater modules like this are commonly used as auxiliary or emergency heat, automatically activating when outdoor temperatures fall below the heat pump’s optimal operating range.

• Robust electrical performance
  Operating at 208/240V and roughly 31.6–36.5 amps, the heater provides consistent heating capacity for larger ducted systems that require additional winter heating support.

• Built-in safety components
  Includes thermal limit cutoffs, relays, and protective fuses to safeguard the system and ensure safe operation during high-output heating conditions.

• Large cabinet design for higher capacity systems
  The large cabinet configuration is designed for larger air handlers and higher heating loads, making it ideal for whole-home ducted heat pump systems.

Q&A

Q: What is the Mitsubishi EH17-MPAS-L electric heater module?
A: The EH17-MPAS-L is an optional 17 kW electric heat kit designed for Mitsubishi PVA multi-position air handlers, providing auxiliary or backup heating for ducted heat pump systems.

Q: What is the heating capacity of the EH17-MPAS-L?
A: This heater module provides up to 17.5 kW of electric heating (240V) or 13.2 kW at 208V, delivering strong supplemental heat when the heat pump needs additional capacity.

Q: How many heating stages does this heater module have?
A: The EH17-MPAS-L features two-stage electric heating, typically split into 8.75 kW + 8.75 kW stages, improving efficiency and system control.

Q: What systems is the EH17-MPAS-L compatible with?
A: It is designed for Mitsubishi PVA multi-position air handlers and compatible ducted systems such as PVA-A42AA4/A7 and select PVFY air handlers.

Q: What voltage does the EH17-MPAS-L require?
A: The heater module operates on 208/240V single-phase power and requires a dedicated electrical supply separate from the outdoor unit.

Q: How is the electric heater module installed?
A: The EH17-MPAS-L mounts directly to the air outlet connection on the air handler, integrating with the ducted system to deliver heated airflow through the existing ductwork.

Q: What are the dimensions of the EH17-MPAS-L heater module?
A: The unit measures approximately 25″ W × 22-13/16″ D × 6″ H, designed to fit large-cabinet PVA air handlers.

Q: Why add an electric heat kit to a heat pump system?
A: Electric heater modules provide auxiliary heating during extreme cold conditions, defrost cycles, or when additional heating capacity is required, ensuring consistent indoor comfort.

Q: Does this heater require additional accessories?
A: Yes. Installations typically require the SPTB1 Separate Power Terminal Block, which allows the heater to receive power from a dedicated electrical source.

Maintenance Tips

• Inspect Electrical Connections: Periodically check wiring, relays, and breakers for signs of wear or loose connections. Electric heat kits operate on 208/240V power, so secure electrical connections are essential for safe operation.

• Keep Airflow Path Clear: Ensure supply ducts and air handler filters remain clean to maintain proper airflow across the heating elements and prevent overheating.

• Check Safety Limits and Breakers: The heater module includes thermal limit cutoffs and circuit breakers designed to prevent overheating—inspect during routine service.

• Maintain Clean Air Handler Components: Dust buildup on blower components or coils can reduce airflow, causing the heater to work harder and lowering efficiency.

• Verify Proper Power Supply: The electric heater requires a separate power supply and should not be powered directly from the outdoor unit.

• Schedule Annual Professional Service: A licensed HVAC technician should inspect heating elements, electrical relays, and safety controls annually to ensure reliable backup heating.
