On a thermostat, "EM heating" stands for emergency heating. It heats your house up very quickly, and is costly to run. This is suppose to be used if you've lost heat from your heat pump or if you've turned your thermostat way down and need to heat up your house quickly.

What does the EM heat mean on your thermostat for your central AC heating unit?
If you have a heat pump A/C unit then you have auxillary heat and emergency heat. The EM stands for emergency heat, which is using only your electric heat strips or gas heat, depending on your system. The auxillary heat uses your compressor inside of your outside unit. Say the house is 60 degrees inside and you set your stat to 70, the temperature difference is so great that if the heat pump alone cannot satisfy, then the auxillary heat would come on to assist the heat pump. Say you were to get a leak in either your condenser or evaporator coils, your heat pump would not work on the regular heat setting on the tstat. In this circumstance you would want to use just the emergency heat until a service tech can evaluate the system.
What is used for heat dissipation in ICs?
heat sinks
Why is there an electric heating coil in a heat pump?
Heat pumps don't work well when the temperature outside drops below 40 degrees Fahrenheit. The way a heat pump works is by absorbing heat from outside and moving inside using the refrigerant. Much like an air conditioner absorbs the heat from inside of your home and moves it out. Therefore the colder it is outside the less heat a heat pump can produce. The reason they install electric heat strips is to ensure that when the temperature outside gets below 40 you will still have enough heat available to heat the property.
How does an electric heat pump work?
An electric heat pump can heat up your home during winter and cool it during summer.
What absorbs and disperses heat produced by electrical components?
heat sink
Should the thermostat be set to EM heat if the heat pump has Auxiliary heat?
Emergency Heat [EM] should only be used as a backup if the heat pump fails. EM heat uses 1.5 to 3 times as much or electricity as the heat pump.
Which setting should iuse on electric thermostat heat or em heat what is difference?
On a system that uses a Heat pump, the heat setting utilizes the pump, and electrical coil heating as a backup. On the EM setting the heat pump won't run, only the axillary coils will provide heat.
What is em heat on a honeywell thermostat?
this stands for emergency heat
Do you put your heat pump em heat when its real cold?
For sure i do
When should you use em heat on the thermostat?
EM (or emergency heat) can be used if you have a problem with your other heat source such as a heat pump. In most cases, you will not need this but what it does is bi-passes the primary heat source and allows your secondary heat source (normally your furnace) to become the primary.
Will I damge my heating system by putting it on em heat?
no
Is the em heat on your thermostat the same as auto heat?
yes it is i am a doctor thats how i know
Which setting should iuse on electric thermostat heat or em heat what is differnce?
These two settings are found when you have a heat pump. Using the "Heat" mode uses the heat pump capabilities alone. Using em heat, turns on conventional electric coils to create more heat (and run up your electric bill)
What EM waves are emitted by fire?
Light (visible) and heat (infrared)
Energy transformations in a projector?
Heat and light energy
What type of EM wave is most often associated with heat?
The ones called "heat waves", or infrared radiation.
What two properties of a em wave change as you move from one part of the em spectrum to another?
frequency and heat. (Color can change, too)
