When the temperature drops below about 35F, the amount of heat the heat pump can deliver decreases and when it can not keep the house warm, the electric coils turn on. The thermostat should turn on the emergency heat automatically when it senses the heat pump is not producing heat. The down side of the emergency heat is it uses 3 to 4 times more electricity to heat then the heat pump does. I am attaching a link from San Diego that gives a simple explanation of how the heat pump and emergency heat works.<br><b>References : </b><br>http://www.sdge.com/forms/heatpumps.pdf The emergency heat are normally electric resistance coils in the furnace when you have a heat pump.
