Introduction
In this article, we will discuss the topic of when to use your emergency heat with a heat pump. We will explore what emergency heat is, how it works, and the situations where it may be necessary to utilize it. Additionally, we will address common concerns and misconceptions related to emergency heat, as well as provide step-by-step instructions on how to turn it on. By the end of this article, you will have a comprehensive understanding of emergency heat and its importance in maintaining the efficiency and functionality of your heating system.
Understanding Emergency Heat
Before diving into when and how to use emergency heat, it is important to understand what it actually is. Emergency heat, also known as auxiliary heat, is a secondary heating source that your heat pump system utilizes under certain circumstances. Heat pumps are designed to extract heat from the outside air and transfer it into your home for heating. However, when the outside temperature drops below a certain point, usually around 30 degrees Fahrenheit, the heat pump's capacity to extract heat becomes limited. This is where emergency heat comes into play.
When to Use Emergency Heat
Knowing when to use emergency heat is crucial in maintaining a comfortable and properly heated home. As mentioned earlier, emergency heat should be used when the outside temperature drops below 30 degrees Fahrenheit. At this point, your heat pump's efficiency decreases significantly, and it may struggle to provide adequate warmth to your living space. By switching to emergency heat, you can ensure that your home remains comfortable even in freezing temperatures.
The Function of Heat Strips
Emergency heat relies on the use of heat strips, also known as heat coils, to provide supplemental heat to your home. These coils consist of a coiled wire that glows and produces heat when a voltage is applied to them. They draw more current than the heat pump itself and can provide a significant amount of heat when activated. However, it is important to note that the use of heat strips should be limited to when necessary, as they consume more energy compared to the heat pump.
Common Concerns with Emergency Heat
One common concern that homeowners have when using emergency heat is the presence of a burning smell. This is completely normal and can be attributed to dust accumulation on the heat strips during periods when they are not in use, such as during the summer or spring. When you initially turn on emergency heat, the dust on the heat strips may burn off, resulting in a temporary burning smell. However, if you notice a significant amount of smoke or flames coming from your registers, it is important to turn off emergency heat and seek professional assistance.
How to Turn on Emergency Heat
The process of turning on emergency heat may vary depending on the type of thermostat you have. For a York 21 thermostat, simply open the flap, pull it down, and switch the thermostat to heating mode. Then, press the emergency heat button to activate it. On an American Standard 402 thermostat, press the mode button until the display shows "emergency heat." By following these simple steps, you can ensure that your emergency heat is activated and providing the necessary supplemental heat to your home.
The Importance of Using Emergency Heat
Using emergency heat when needed is crucial in preventing potential damage to your heat pump system. When the outside temperature drops below freezing and you rely solely on the heat pump, it can strain the equipment and cause it to run continuously without achieving the desired temperature. This not only leads to reduced energy efficiency but can also result in damage to components such as the fan motor and outdoor coil. By utilizing emergency heat, you can prevent these issues and avoid costly repairs.
Potential Damage Without Emergency Heat
Failing to switch to emergency heat during freezing temperatures can result in several potential damages to your heat pump system. For example, snow or ice can accumulate on the top part of the outdoor unit, obstructing the fan motor and causing it to burn out. Additionally, the blades of the fan can break and damage the outdoor coil, leading to expensive repairs. By proactively using emergency heat, you can prevent these damages and prolong the lifespan of your heating system.
Different Types of Thermostats
There are various types of thermostats available, each with its own method of activating emergency heat. Some thermostats, such as the York 21 thermostat, have dedicated emergency heat buttons that can be easily pressed to activate it. Others, like the American Standard 402 thermostat, require navigating through the menu settings to select emergency heat. Familiarize yourself with the specific features and functions of your thermostat to ensure you can quickly and efficiently activate emergency heat when needed.
Conclusion
In conclusion, understanding when and how to use your emergency heat is essential for maintaining a comfortable and efficiently heated home during extreme temperatures. By following the guidelines outlined in this article, you can ensure that your heat pump system operates effectively and avoids potential damages. Remember to switch to emergency heat when the outside temperature drops below 30 degrees Fahrenheit and familiarize yourself with the process of activating emergency heat on your specific thermostat. Stay warm and cozy by utilizing emergency heat when necessary.

Highlights
- Emergency heat, also known as auxiliary heat, is a secondary heating source used in conjunction with heat pump systems.
- It is important to switch to emergency heat when the outside temperature drops below 30 degrees Fahrenheit to maintain a comfortable indoor temperature.
- Emergency heat relies on heat strips or coils to provide supplemental heat, which consume more energy compared to the heat pump itself.
- A burning smell may occur when using emergency heat due to dust accumulation on the heat strips, but excessive smoke or flames should be addressed immediately.
- Activating emergency heat can vary based on the type of thermostat, so it is crucial to familiarize yourself with the specific instructions for your thermostat model.
- Utilizing emergency heat when needed prevents potential damage to the heat pump system, such as motor burnout and damage to the outdoor coil.
- Neglecting to use emergency heat during freezing temperatures can lead to costly repairs and decreased energy efficiency.
- Different types of thermostats may have dedicated emergency heat buttons or require navigating through menu settings to activate it.
FAQ
Q: Can I use emergency heat all the time?
A: It is not recommended to use emergency heat as a primary heating source on a regular basis, as it consumes more energy and can increase your utility bills. It should only be used when the outside temperature drops below 30 degrees Fahrenheit or when the heat pump cannot adequately heat your home.
Q: How often should I clean the heat strips?
A: It is not necessary to clean the heat strips regularly. However, if you notice a significant accumulation of dust or debris on the heat strips, you can gently brush them off to prevent any potential burning smells when emergency heat is activated.
Q: Can I damage my heat pump by using emergency heat too often?
A: Using emergency heat occasionally during freezing temperatures will not cause damage to your heat pump. However, relying solely on emergency heat for extended periods can strain the system and potentially lead to increased energy consumption and wear on the heat strips.
Q: What should I do if I smell smoke or see flames when using emergency heat?
A: If you notice excessive smoke or flames coming from your registers when using emergency heat, immediately turn off the emergency heat and contact a professional HVAC technician. This could indicate a more serious issue that requires professional assistance.
Q: Are heat strips necessary for all heat pump systems?
A: Heat strips, or auxiliary heat, are necessary for conventional heat pump systems to provide supplemental heat when the outdoor temperature drops below a certain threshold. However, VRF mini-split heat pump systems do not rely on heat strips and can operate efficiently even in colder temperatures.
