What is auxiliary heat. Auxiliary heat is a heat pump thermostat set. If a heat pump is having a challenging period coming up to a particular temperature fast due to excessively chilly outdoor temperatures, the “aux heat” arrow indicates that a secondary heat basis (commonly gas or electric) has been deployed.
The distinction Between Auxiliary & Emergency Heat:
In Florida, you have got three forms of heating sources along with your HVAC system: For this discussion, we are going to specialize in the distinction between a conventional heater/furnace and an apparatus system. Several Floridians WHO lived up North don’t perceive the difference between auxiliary heat and emergency heat.
What’s the Difference?
Auxiliary heat is mechanically activated once there’s not enough doors heat. During this mode, the warmth pump continues extracting the maximum energy as doable. However, it conjointly adds heat from a secondary supply to form the distinction.
This secondary heat supply is often electrical heating coils integrated into the system. As out of doors temperatures rise, and secondary heat isn’t any longer needed, the unit mechanically turns off the auxiliary electrical coils.
Emergency heat may be a mode the user manually selects if the unit isn’t providing heat for a few reasons, like a malfunction. Emergency heat activates the secondary heat supply to supply 100% of needed heat. The system continues to control in emergency mode till the user manually turns it off.
Summary:
AN example once emergency heat could also be used can be once a section has been ordered for a required repair and your HVAC skilled has shared that by changing to emergency heat, your home can still heat for your family.
What area unit Auxiliary Heat & Emergency Heat?
Auxiliary Heat – this can be the secondary heat supply that activates mechanically.
Emergency Heat – this can be after you activate the secondary heat supply.
The distinction between auxiliary heat and emergency heat is just the name. Each heat area unit has the same heat components; however, the area unit is labeled otherwise.
Auxiliary Heat:
Here in Everglade State, we usually use the warmth pump for our primary supply of warmth once heating the home; but, this unit conjointly contains a limit. An apparatus will satisfy your home’s heating wants as long as the out of doors temperature remains at or higher than forty-five degrees.
At temperatures around forty-five degrees, the skin coil will and can freeze up, which can cause the system to travel into de-ice mode. Whereas in de-ice manner, the out of doors unit can signal the air handler to show on the auxiliary heater.
This heater is an electrical heater like a kitchen appliance and can offer supplemental heat to the house, whereas the outside door unit defrosts itself.
Summary:
Once the release of the doors system is defrosted, the auxiliary heater turns off, and the system continues in apparatus mode.
Emergency Heat:
-
Emergency heat may be a term we tend to use for once the house owner should force the system into the electrical heating mode if their apparatus system has been unsuccessful or isn’t operating correctly.
-
This heater is the same because the auxiliary part is solely employed in a distinct format.
The heater is often not designed to heat your home to eighty degrees, however solely as a supplement heat supply. In contrast, the warmth pump is in de-icing mode or as AN emergency backup in a system failure.
Auxiliary Heat’s Functions:
The first performance is to copy the warmth pump if the thermostat contains a distinction of three degrees or a lot of from the set temperature to the particular temperature within the house. If this happens, the warmth pump and strips can run along to form hotter air to heat the home efficiently. Once the thermostat point is among two degrees of the temperature within the house, the auxiliary heat can be put off.
The second performance is once the out of doors system goes into de-ice mode, as declared higher.
When we kick off to try and do our 77-point listing on your system, we’ll kick it into de-ice mode to form positive it’s operating. We essentially freeze the system up and create the instrumentation work a touch more durable to form positive you’ll have heat after you want it.
Which is Better?
If out of doors temperatures briefly drop and your apparatus will not extract enough heat, the correct mode is automatic auxiliary heat. During this mode, the warmth pump still contributes the maximum amount of heat, minimizing demand from electrical heating coils. In emergency mode, conversely, the warmth pump performance is entirely disabled, and also the system depends entirely on secondary heating coils.
As a result of electrical heating, waves consume scores of electricity, heating prices within the emergency mode can increase dramatically if systematically used for long periods of your time.
Why you must ne’er Use Emergency Heat (unless you have entirely to):
Before you bit that Emergency Heat setting on your thermostat, scan this! The Emergency Heat or Auxiliary Heat setting is the second stage of your heating plant used once the temperature is too low for the warmth pump to take away heat from outside, usually below thirty-five degrees Fahrenheit.
Your heating plant will then use the alternate supply to supplement the warmth. However, if you force the system into the Emergency Heat mode, it becomes the only energy supply instead of its supposed performance.
Switching your Thermostat to Emergency Heat will Lead to:

High energy bills:
The cost of running your home on Emergency Heat would be astronomical. Turning to the current setting switches your heat supply from the warmth pump to the electric heat strip, which is considerably less economical and a lot pricey.
Taxing your system:
Turning on emergency heat forces your system to bypass the warmth pump altogether and work like most heat supply isn’t engaging at all. This puts an excellent strain on the backup part that’s solely meant to be employed in extreme circumstances for brief periods of your time.
When operating correctly, your heating plant can utilize your Emergency Heat once the first system cannot handle dominant temperature on its own or there’s a haul along with your heating plant. If your fan doesn’t activate either, set your thermostat; therefore, the system doesn’t be. While not air movement, emergency heat will cause injury to your out of doors unit. You must ne’er activate the Emergency Heat manually unless your apparatus has been unsuccessful entirely.
If that’s the case, you must have your heating unit examined and repaired like a shot. If you want to activate the Emergency Heat, don’t hesitate to get in touch with Wentzel’s and permit the North American nation to handle the underlying issue.
Summary:
Remember, don’t switch to Emergency Heat simply because it’s cold; solely do this if your apparatus isn’t any longer heating your home the least bit.
Auxiliary heat is required when:
The temperature outside is below freezing.
Heat pumps have one drawback:
They lose potency because the temperature drops.
Heat pumps area unit extremely economical to concerning 32°F. Below phase transition, your apparatus merely can’t draw enough heat from the cold air outside and can kick on its auxiliary heat mode to come up with heat for your home.
So, before your decision is an expert to diagnose a haul, check the out of doors temperature. If it’s a strangely cold day in San Marcos, don’t be shocked to examine “AUX heat” on the thermostat.
Your thermostat is looking for a hot temperature increase:
When the temperature within your house is over 2–4°F higher than your thermostat’s set temperature, the auxiliary heat can activate. (The actual temperature differential can rely on your apparatus model.)
This happens as a result of your system is attempting to come up with a great deal {of heat|of heatth} to warm your home faster than it might with traditional apparatus heating. Once the within temperature reaches the set thermostat temperature, your system should return to victimization conventional apparatus heating.
Summary:
To avoid this downside, we tend to advocate limiting; however, typically, you raise the temperature over 2–4°F.
The heat pump is in de-ice mode:
Although we tend to don’t get a great deal of sub-freezing temperatures in San Marcos, your apparatus may enter what’s referred to as “defrost mode,” which prevents your out of doors unit from phase transition over.
In de-ice mode, your system can run in cooling mode for a couple of minutes to permit the coils within the outside doors unit to heat up.
You’ll recognize your system is in de-ice mode if the out of doors fan has stopped current and you see puffs of steam returning from the unit. Some models even have a blinking lightweight on the out of doors unit that indicates your unit is in de-ice mode.
Summary:
During de-ice mode, your system can use auxiliary heating to heat your place in the meantime. The warmth pump ought to sit back to traditional heating mode once a couple of minutes.
