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.
The auxiliary heat typically comes on when the set temperature is raised by 2-4 degrees higher than the current room temperature. This can vary based on the specific HVAC system and thermostat settings. It is designed to help the primary heat source keep up with the desired temperature in colder weather.
A heat pump thermostat.
Hi, I had the same issues, I would gather to say it is the thermostat.
In a hot water heater, a thermostat regulates the heat
check to see if your thermostat is workin properly.Is there any heat at all after say,a 20 minute drive?
Any brand or make will work if it is 2 heat 1 cool thermostat
If thermostat does not open - Vehicle will overheat in a short time - no heat If thermostat does no close - vehicle will not get to normal operating temperature - no heat
NO, But it is expensive.
A programmable thermostat works fine with a heat pump. Just remember that a heat pump does not heat as fast as a furnace because of the lower BTU ratings so do not set the thermostat as far back as you normally would. Also make sure to buy a thermostat that has heat pump terminals.
If i remove the thermostat will i get heat
this stands for emergency heat
