When should you run emergency heat?

It is used when there is something wrong with first-stage heating (the Heat Pump itself). In other words, if you notice your house is cold and it isn’t heating properly and you went outside and noticed that a tree fell and crushed your heat pump, that would be a good time to switch to Emergency Heat.

Is it better to turn on emergency heat?

Short answer: No. Switching your thermostat to emergency heat or “em heat” just because it’s cold outside will just raise your energy bills like crazy. Don’t use emergency heat mode unless your heat pump stops heating your home altogether. If that happens, contact a professional heat pump repairman for help.

At what temperature is a heat pump not effective?

between 25 and 40 degrees Fahrenheit

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.

What is the drawback of emergency heat?

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 temperature should I set my heat pump in the winter?

Ideal Winter Heat Pump Temperature Settings

According to the Department of Energy, 68°F is the sweet spot that balances comfort and energy efficiency during the fall and winter months. When your home is occupied and when family members are awake, a heat pump setting of 68°F keeps the living areas reasonably warm.

Why is my emergency heat blowing cold air?

Defrost mode basically means your heat pump temporarily switches to cooling mode. This forces the outdoor coils to heat up, melting any frost or ice that has built up. And because the heat pump switched to cooling mode, it will blow cold air into your home for a few minutes.

Should I turn my heat pump off in extreme cold?

But you probably wonder,should I turn my heat pump off in the extreme cold? Well, the answer is no. you do not have to turn the heat pump off in the extreme cold. In the past, some heat pumps thrived even in extremely cold temperatures while others were disadvantaged.

What is the difference between heat and emergency heat?

To put it simply, a heat pump is “first stage” heating, and emergency heat is a “second stage” or “back up” heating source. When emergency heating is activated will depend on your thermostat system, as each system will have a different way of determining when emergency heat is needed to assist first stage heating.

Does emergency heat use more electricity?

Drawbacks of Emergency Heat

In comparison to relying on a heating pump alone, emergency heat is much less energy efficient. Though the emergency heat setting does represent a means for warming up homes, it can cost twice what the heat pump costs in utility expenses.

What does the emergency heat setting on my thermostat do?

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.

What is the difference between heat and emergency heat?

To put it simply, a heat pump is “first stage” heating, and emergency heat is a “second stage” or “back up” heating source. When emergency heating is activated will depend on your thermostat system, as each system will have a different way of determining when emergency heat is needed to assist first stage heating.

Should I turn my heat pump off in extreme cold?

Short answer: You should only set your heat pump’s thermostat to “emergency heat” when your heat pump stops heating altogether.

How long can I run emergency heat?

Em heat vs. aux heat

Will emergency heat defrost heat pump?

The heat pump should run its defrost cycle automatically, but if it isn’t thawing itself then it may need to be manually switched on. Again, not all systems may have an option to manually run the defrost cycle, at least not easily. You will have to do some research on your particular system in order to confirm.
