How to Choose the Right Heat Type for Your PTAC Posted on May 23, 2024 Packaged Terminal Air Conditioners (PTACs) are a popular choice for cooling and heating residential and commercial spaces, thanks to their versatility and efficiency. When it comes to PTAC heating, however, not all are created equal. There are two different types of PTAC heating systems, each with its own set of advantages and disadvantages. In this article, we explore both types of PTAC heating options, discuss their respective pros and cons, and provide guidance on how to select the best one for your specific needs. The 2 Types of PTAC Heating When it comes to heating, PTACs use one of two different systems: heat pumps and electric resistance heating. PTAC Heat Pump As the name suggests, some PTAC models are equipped with a reverse cycle heat pump to provide warmth through conduction. The heat pump works by reversing the flow of coolant. In doing so, it absorbs heat from the outside air and transfers it to the home’s interior. This makes it more efficient than electric heating, but comes with a higher initial price tag. Pros: Heat pumps are more energy-efficient than electric resistance heating. They draw between 25% to 60% less wattage than electric heating units, which makes them more cost-effective in the long run. They are also more eco-friendly, since they generate less greenhouse gas emissions than electric resistance heating. Cons: Heat pump PTACs are slightly more expensive to purchase upfront compared to electric resistance units. Heat pumps are less efficient in extremely cold weather, and will switch to backup electric heat. This changeover generally happens between about 25-40° F outside depending on the unit and specific conditions. Since the heat pump draws in heat from outside, heating performance tends to be affected by external weather conditions. Keep in mind that because of the backup electric heat strip in heat pump units, you will always have heating, regardless of the outside temperature. Electric Resistance Heating The other option is electric resistance heating. In this setup, the heat is generated by passing electric current through a resistive element. This makes them simpler and less expensive, but also less efficient compared to heat pumps. Pros: Electric heating PTACs generally carry a lower price tag. They are easier to maintain. It provides quicker palpable warmth as the resistance element heats up faster than a heat pump. Emits less noise than a heat pump. Cons: Electric resistance heating is less efficient and is more costly in the long term. Its lower efficiency also means it’s less eco-friendly due to its high energy consumption. How to Choose the Right PTAC Heating System ✔ Local weather Heat pumps perform best when the outside air temperature is above freezing. Once it drops down below the 20s, their performance suffers compared to electric heat. Most heat pumps typically work best between 35-55 degrees F. For most regions of the country, that means that a heat pump will be saving you money for a good portion of the winter and will switch to electric heat when needed. ✔ Budget PTAC heat pumps carry a higher price tag than their electric heat counterparts. However, this can be offset by energy savings in the long run. ✔ Utility rates Electric resistance heating is less efficient and consumes more energy than a heat pump. If your area’s utility costs tend to be high, consider choosing the heat pump despite being more expensive. The higher initial cost will pay for itself in the long term, especially if you use the heating function frequently. ✔ Noise Electric heating is quieter than heat pumps, since it only requires a blower to disseminate the heat across the room. Heat pump units use the unit’s compressor which means it will sound the same as the air conditioner portion of the unit running.
