Usually a backup heating unit. For instance in a heat pump when the temperature drops below the temperature where the heat pump cannot extract heat from the existing air electric heating elements kick in.
NO, But it is expensive.
None. There is no difference. Auxiliary heat and Emergency heat are synonymous. It is the electric heat strips that kick on whenever the outside temperature drops too low (below 30 degrees or thereabouts) for the heat pump to efficiently heat the house. The electric strips are a little more expensive to run, but they will heat the house.
Auxilary heat is a second source of heat when your primary source can not keep up on it's own (either electric or gas).
If there are lines coming from the transmission to the radiator, it has a cooler in the radiator. If there are lines from the transmission to an external heat exchanger, that would be an auxiliary cooler.
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.
For a 1999 Lincoln Navigator : Assuming you want a 50 / 50 mixture of antifreeze and distilled water ( like it was from the factory ) With auxiliary rear heat ( approximately 14 U.S. quarts ) Without auxiliary rear heat ( approximately 13 ) * of antifreeze *
During an emergency. i.e. when the heat pump is not working. If your heat pump can not keep your house warm, then the auxiliary heating coils (same thing as emergency heat) will come on automatically. If not, then there is a problem with your heating system.
Auxilliary heat is on... Change the filter... Then reset the filter change reminder and if the filter is not dirty extend the filter chamge reminder for a longer interval.
Auxiliary Boiler is Auxiliary Boiler thats it.
If you have a heat pump and the breaker blows in heat cycle then you probably also have auxiliary electric heat which is drawing too much current because of a faulty heater element.
is can a main verb??
Auxiliary sound refers to auxiliary interface connector where one can connect external sound devices.
