Heat Pump & Exactly what To Glance Pertaining to In order to Manage & Servicing Your personal Heat Pump - Local Support Centre

A heat pump normally takes heat externally and moves it in your home.  Even freezing winter air has some heat, and heat pumps can extract heat from the outside air on a cold day and transport it indoors to manage a comfy temperature.  It does this by operating as a refrigeration system - basically an air-conditioner running in reverse.  If the heat pump is consuming heat from the outside air, the efficiency of the heat pump decreases as the outdoor air temperature lowers. The colder it is, the more difficult it gets to draw out and move heat.



The efficiency of a heat pump varies substantially with the outdoor temperatures. While a heat pump may be twice as efficient as a standard heating system at 50 degrees F, when the outdoor temperature drops to less than 30 degrees, extra electric resistance heating kicks in.  At very low outdoor temperatures, the heat pump compressor will shut off completely and the backup heating system takes over - using much more electricity.  Most smart thermostats support many stages of heating and cooling, and can run the heat pump and auxiliary heat at the same time to increase comfort and minimize overall energy costs.



In case of compressor or general system malfunction, many thermostats have an emergency heat switch that bypasses the thermostat and triggers the supplemental heater.  You may have noticed that after a power outage, the supplemental electric resistance heater runs for a while to heat up the house.  This is common, as the system is designed to reheat the oil in the crankcase of the compressor before restarting the compressor.



If you notice that your system is heating but the outdoor compressor is not running, or if the emergency heat light is on, there could be several reasons for this.  The power might be off to the outdoor unit because of a blown fuse or tripped circuit breaker.  A very dirty air filter, or debris on the outside unit could also be the main problem.  Drastic changes to the settings on the thermostat might also push the system into emergency heating mode.



If the auxiliary or emergency heat light is constantly on when the unit is heating, there is probably some problem with the system.  A service specialist can quickly check if the system is low on refrigerant, or if there is a more major problem. Keep an eye on your thermostat light and your system, as well as your electric bill.  If there is an increase in electrical usage for no recognizable reason, you may have a heat pump operating on costly backup electric resistance heat.
