Before you touch that Emergency Heat setting on your thermostat, read this! The Emergency Heat or Auxiliary Heat setting is the second stage of your heating system that is used when the temperature is too low for the heat pump to be able to remove heat from outside, typically below 35 degrees Fahrenheit.
Similarly, Does emergency heat come on automatically?
Your emergency heat setting automatically turns on when outside temperatures drop below a certain temperature, usually 30 degrees Fahrenheit. If you need to manually turn it on, you should call an HVAC professional to get your heat pump fixed.
Additionally, At what temperature does a heat pump switch to emergency heat? Emergency Heat, also known as “auxiliaryheat”, is the second stage ofheatthat your thermostat runs on when the temperature is too cold for yourheatpump to extract heatfrom the outside. Emergency Heat is typically triggered when it is 35°F and below outside.
Does emergency heat cost more?
Using Emergency Heat May Cause Higher Heating Bills: Emergency heat is more expensive than its traditional counterpart, so you will probably see a spike in your utility bills if you need to use it. You should use emergency heat for the shortest period of time possible.
What is the difference between auxiliary heat and emergency heat?
Auxiliary heating turns on automatically to help heat your home more quickly if the temperature drops suddenly. The emergency heat setting has to be manually switched on and should only be used in temperatures below 30 degrees.
How do you know if your emergency heat is on?
Emergency Heat Mode Comes with a Red Indicator Light: When you turn your emergency heat on, you will see a red indicator light. This light tells you that your HVAC system is now operating in emergency mode, and it will remain on until you deactivate your emergency heat.
Why does my heat only work on emergency heat?
You should only use your heat pump’s emergency heating mode when it’s truly an emergency (e.g., your heat pump isn’t working in winter) because manually overriding your system means it won’t run as efficiently as it can—which will result in higher energy bills.
How do I turn on ecobee emergency heat?
To enable this system mode, go to Main Menu > Settings > Installation Settings > Thresholds > Auto Heat/Cool and select Enable.
At what temperature do heat pumps become ineffective?
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Do heat pumps work below 20 degrees?
You can run a heat pump at all temperatures as it is designed to switch to emergency heat when it reaches below 25-30 degrees Fahrenheit. … Your heat pump will simply recognize that it is not functioning efficiently if it gets too cold, and will switch to its alternative emergency heat setting.
What is the temperature range for a heat pump?
Typically, heat pumps have cooling operating temperature range of 15°F to 115°F (-10°C to 46°C). This means that if you live in ANY part of USA, a heat pump will provide adequate cooling.
What is the drawback of emergency heat?
What is the drawback of emergency heat? The supplemental heat costs more to operate than a heat pump.

When should you use auxiliary heat?
AUX heat refers to your heat pump’s “backup” electric resistance heating. This heat setting should only kick on when the heat pump can’t produce enough heat to warm your home or if your heat pump goes into defrost mode.
What is auxiliary heat?
Auxiliary heat on your thermostat refers to your backup heating system within your heat pump, otherwise known as electric resistance heating. Your thermostat inside your house is actually what determines when the auxiliary heat gets turned on.
Is it bad if auxiliary heat comes on?
Is AUX heat bad? The short answer is no. In fact, aux heat is a critical mechanism that keeps your heat pump properly running when the outdoor temperature drops. Since this type of unit doesn’t work the same as a furnace, it can get cold.
What happens when you turn on emergency heat?
Emergency heat=using the electric heat strip constantly
OK, so when you turn your thermostat to emergency heat, your heat pump will stop trying to extract heat from outside to heat your home inside. Instead it will use ONLY the backup heat strip to heat your home. So, your heat pump has now become an electric furnace.
How do I turn off emergency heat on my Honeywell thermostat?
One of the simplest things you can do to keep your Honeywell thermostat from switching to auxiliary heat is to lower the temperature in your home. Setting the thermostat for somewhere between sixty to sixty-eight degrees is all you should need to do to get the problem under control.
Why does my heat pump keep switching to auxiliary heat?
Most heat pumps are designed to automatically switch to AUX heat when the indoor temperature is 3 degrees colder than the thermostat setting. … So first, check to see if your thermostat only says AUX when you raise the thermostat 3 degrees or higher than the current temperature of your home. If so, that’s normal.
Why is my auxiliary heat not coming on?
Clogged Air Filter/Dirty Coil/Restricted Ductwork
The most common cause of this failure is low airflow across the heaters. The most common source of low airflow is a clogged air filter, but can also be caused by a dirty indoor coil or closed/restricted ductwork.
Does Ecobee have emergency heat mode?
Some thermostats for heat pumps have an E terminal, which toggles emergency heat on or off. Emergency heat should only be used on very cold days when the heat pump is unable to keep the house warm. The E wire normally connects to the ecobee’s W1 terminal.
What is auxiliary heat on ecobee?
Increase the Value of Your Aux Heat Threshold
Auxiliary heat is basically a complimentary system attached to your HVAC that kicks in whenever your heating system cannot heat the room to the set temperature on its own.
How do I turn off auxiliary heat?
Shut the door and close the vents so that the rest of the warm air can be redirected to the rest of your home. If the temperatures are extremely frigid outside, even this may be too much for your unit. You may need to make some additional changes to your home to keep the auxiliary heat from coming on.
