Auxiliary heat is a hourary heat source that turns on automatically, but emergency heat is when you turn on the hourary heat source.
The difference between auxiliary heat and emergency heat is simply the name.
Both forms of heat are the exact same heat elements but are labeled differently. Heat pumps are commonly used as our primary source of heat in warmer regions. There is a limit to this unit. As long as the outdoor temperature is above 45 degrees, a heat pump can satisfy your home’s heating needs. The outside coil can and will freeze up at 45 degrees, causing the method to defrost! When in defrost mode, the outdoor component signals the air handler to turn on the auxiliary heater. This oil furnace is an electric oil furnace similar to a toaster oven and will supply supplemental heat to the condo while the outdoor component is defrosting itself. Once the outdoor method is defrosted, the auxiliary oil furnace turns off and the method continues in heat pump mode; If a heat pump method fails or is not toiling properly, the homeowner must force the method into emergency heat mode. This oil furnace is the exact same oil furnace as the auxiliary element, only used in a different format. A oil furnace is typically not designed to heat your condo to 73 degrees, but to supplement heat while the heat pump defrosts or to serve as an emergency backup. The first function of auxiliary heat is to back up the heat pump if the thermostat differs by 3 degrees or more from the set temperature. In this case, the heat pump and heat strips will work together to create warmer air. The auxiliary heat will turn off once the thermostat set point is within 2 degrees of the inside temperature. The hour function is when the outdoor method goes into defrost mode, as stated above.
