🏠 Introduction: Heating Your Space Efficiently
When choosing a PTAC (Packaged Terminal Air Conditioner) unit for your apartment, hotel room, or multifamily property, you’ll encounter two heating methods: heat pumps and electric heat backup. Understanding the differences between them will help you optimize comfort, save on energy costs, and avoid heating issues during cold weather.
The Amana Distinctions 14,700 BTU PTAC offers both options, making it a versatile choice. But how do these systems work, and which one suits your climate and budget best?
⚡ What Is a Heat Pump in a PTAC Unit?
A heat pump in a PTAC unit operates by reversing the refrigeration cycle to extract heat from the outside air and bring it indoors, even in cool weather. In cooling mode, it works like a traditional air conditioner, moving heat from indoors to outdoors.
Key benefits:
-
Uses less electricity than electric resistance heating.
-
Provides both heating and cooling in one system.
-
Efficient in mild to moderate climates.

🔋 What Is Electric Heat Backup?
Electric heat backup (electric resistance heating) uses electric heating elements within the PTAC to generate heat directly, similar to how a space heater operates.
Key benefits:
-
Provides reliable heating even in freezing temperatures when heat pump efficiency drops.
-
Simple operation with minimal moving parts.
-
Useful in colder climates where heat pumps alone may not suffice.

🌡️ Efficiency Comparison: Heat Pump vs Electric Heat Backup
Heat pumps are significantly more energy-efficient than electric resistance heating in mild and moderate climates because they move heat rather than generate it directly. According to the EPA, heat pumps can reduce electricity use for heating by up to 50% compared to electric resistance heating.
However, heat pump efficiency decreases as outdoor temperatures drop below 35°F (1.6°C), requiring electric backup to maintain heating performance.
💸 Cost Differences Between Heat Pump and Electric Heat Backup
Heat Pump Operating Costs: Lower in mild climates due to efficient heat transfer.
Electric Heat Backup Operating Costs: Higher due to direct electricity consumption but necessary in freezing conditions.
Using the heat pump as the primary heating source while reserving electric backup for extremely cold days can save significant money while ensuring comfort.

🗺️ Climate Considerations for PTAC Heating
-
Mild Climates (above 35°F): Heat pumps can efficiently handle most heating needs, minimizing the use of electric backup.
-
Cold Climates (below 35°F frequently): Electric heat backup becomes essential, as heat pumps lose efficiency in frigid temperatures.
-
Variable Climates: A PTAC with a heat pump and electric backup, like the Amana Distinctions model, automatically switches to electric heat when necessary, providing seamless comfort.

🛠️ How Does a PTAC Unit Switch Between Heat Pump and Electric Backup?
PTAC units equipped with both heating methods use sensors to detect outdoor and indoor temperatures. When the outdoor temperature drops below the heat pump’s efficiency threshold, the system automatically activates the electric heat backup.
This seamless switchover ensures consistent comfort without requiring manual adjustments, reducing the risk of cold air blowing during freezing conditions.

🏨 Heat Pump and Electric Heat Backup in Hospitality and Apartments
Hotels:
-
Heat pumps reduce energy bills during mild weather while maintaining guest comfort.
-
Electric backup ensures reliable heating in extreme cold, preventing guest complaints.
Apartments:
-
Zoned comfort and cost efficiency for landlords and tenants.
-
Lower operational costs during shoulder seasons.
-
Backup heat ensures consistent heating during cold snaps.
🧩 Pros and Cons: Heat Pump vs Electric Backup
| Feature | Heat Pump | Electric Backup |
|---|---|---|
| Efficiency | High in mild climates | Low |
| Heating in cold climates | Limited below 35°F | Excellent |
| Operating cost | Low | High |
| Environmental impact | Low | High |
| Comfort | Good | Excellent backup |
🧹 Maintenance Tips for Heat Pump and Electric Backup PTACs
Regardless of the heating method, maintaining your PTAC ensures efficiency:
-
Clean filters monthly.
-
Check and clean coils each season.
-
Inspect drainage to avoid leaks.
-
Test the system in both heating modes before seasonal transitions.
