Can I use emergency heat all winter?





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.

Why is my emergency heat not working?

Check your power source—a tripped circuit breaker or blown fuse could be the reason for your furnace failure. Reset your breaker or replace the fuse to see if that restores heat. Check your filter—if it’s so dirty that your system is struggling to move air through it, your furnace could overheat and shut down.

At what temperature should I use emergency heat?

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 run emergency heat?

The only time that you should activate emergency heating is if your heat pump is broken. Also, you should only use it temporarily until you can get your heating system fixed.

Will my heat pump automatically switch emergency heat?

Your heat pump is an intelligent machine. It has settings that tell it when its efforts to heat your home aren’t working and automatically switches to second-stage heating. When the target temperature is reached, the backup heater turns off and first-stage heating resumes.

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.
