what is Emergency Heat? Emergency heat is a secondary power source in the thermostat. Emergency heat is also known as Ancillary Heat. Its short form is EM.
Emergency Heat becomes active when the temperature drops more than 30 degree Fahrenheit.

What is emergency heat?Â
People often think that when you feel colder than usual, it’s time to turn on your emergency heat. This is not how we should use Emergency Heat.
So what is Emergency heat? It’s a secondary power source in the thermostat. As the name indicates, it’s a backup system if your heat pump stops working or the heat pump’s primary system cannot provide heat.
Emergency heat is an option for an emergency, like when the heat pump is covered with ice due to extremely cold weather and can no longer provide heat. Just go for a switch on the emergency heat.
WHEN SHOULD EMERGENCY HEAT BE ON?
Now that you know what is emergency heat? You should also know when it should be on. When the climate is too cold, and the temperature drops down, you can activate the Emergency Heat Thermostat backup system. It helps to maintain the temperature inside when the temperature outside drops down more than 40 degrees. Â
It is better to check the outside heat pump during the cool season. It should not be frozen and become a reason for your problem. Emergency Heat can provide heat to indoor units until the heat pump gets repaired.
Is it essential to switch on EM Heat? There is no need to switch to the EM heat setting manually. When the setting is on, your thermostat will automatically turn on a light and keep you aware that your thermostat is in emergency mode. If you have not turned on Emergency mode and the light is on its means, your heat pump is most malfunctioning.Â
IS EMERGENCY HEAT COSTLY TO USE?
Emergency expensive? Well, it depends on the price of gas or oil you have kept for backup. But running Emergency Heat instead of a heat pump can be more costly. ElectricEmergency Heating systems can be more expensive than alternative options like gas or hot water systems.Â
Parts of the outside heat pumps consist of essential elements that work more effectively. Don’t Activate the it Unless your heat pump has entirely broken; you should never manually turn on the Emergency Heat.Â
How much more expensive is Emergency heat?
Emergency heat backup setting costs 163.80$ per week, which is $700 a month. EM is costly for money, but what it offers doesn’t sum equal that.
BENEFITS OF EMERGENCY HEAT
If your heat pump has an emergency heat system, you don’t need to worry about emergencies. If there is too cold weather outside and the heat pump’s primary system doesn’t have the power to control the weather, then it can be beneficial. Â
On the other hand, if the primary heat provider system stops working for some reason, you can switch on the emergency heat system for a short period until the primary heat provider starts working.Â
How Your Heat Pump Works with EM Heat
In a typical mode, a heat siphon works by pulling in heat from an external perspective. The heat siphon setting’s emergency heat will typically turn on and off naturally during brief periods when the external air gets excessively cold.
Your heating framework will then, at that point, utilize the optional framework with your ordinary heating. In any case, assuming your heat siphon continually changes to backup heat, even in gentle temperatures, this demonstrates an issue, and a specialist should look at it.
Then again, physically enacting your EM heat creates an alternate chain of occasions. The framework will sidestep the fundamental heat siphon and be constrained into assistant mode. At that point, it depends exclusively on the reinforcement heat source to produce heat, just utilizing the indoor unit as a wellspring of heat.Â
Summary
Where does emergency heat come from? This could be a reinforcement gas heater, an electric heat strip, oil, or a high-temperature water framework. If your EM heat is electric, you can expect a lot more high costs when running your EM framework.
Frequently Asked Questions (FAQS)Â
Here are some of the Frequently asked questions related to the article What is emergency heat:
1. How much does emergency heat cost?
While working in the helper/emergency heating mode, that cost is around $1.30 each hour. Assuming your heat siphon is working in helper/emergency mode without due cause (outside temperatures are above freezing or no radical acclimation to your indoor regulator), it is conceivable that your framework is breaking down.Â
2. When Should I Use EM Heat?Â
You shouldn’t because EM works automatically. If your heat pump is faulty, this is the only time you should use emergency heat that is broken. Additionally, it would be best to use it temporarily until your heating system is repaired.Â
3. Is it OK to run emergency heat?Â
There will no issue related to health or hazards but it may increase your bills. To set your thermostat to emergency heat without emergency or because it’s cold outside will raise the price of bills. Avoid using emergency heat mode unless your heat pump is no longer heating your home altogether.Â
4. What is the drawback of emergency heat?Â
Emergency heat is substantially less energy efficient than the heating pump. Use of emergency heat setting might help warm up a home; it can cost twice as much as a heat pump in terms of electricity expenditures.Â
5. Do heat pumps work below 20 degrees?Â
When temperatures dip below 20 degrees Fahrenheit, heat pumps lose efficiency. When the temperature is over 40°F, a heat pump works well. Heat pumps lose efficiency when external temperatures dip below 40 degrees and require more energy to operate.Â
6. Can you use emergency heat during rain?Â
 No, When the primary source – your heat pump – fails, the emergency heat should only be turned in an emergency. If ice is fully covered on the heat pump and damages your outdoor unit, you should turn on your emergency heat.Â
Conclusion
What is emergency heat? Emergency heat is short for EM also known as ancillary heat. It is a mechanism that controls and manages your house’s backup heat system. If you have an EM thermostat setting, you most likely have a heat pump, gas, petroleum, electric, or hot-water backup method.Â
Whenever there is a malfunction in the first heat thermostat setting or the temperature drops from the threshold amount, the EM backup thermostat setting works.
So, in short, emergency heat is a backup heat generator in case the front or main system brokes or temperature drops more than it should.
