During the winter season, the need to maintain warmth within our homes intensifies, prompting many of us to rely on heating systems. However, when we check out the settings on the thermostat, confusion often arises regarding the roles and functionalities of auxiliary and emergency heating. Efficient Systems, Inc., one of the top HVAC services providers and residential plumbing contractors in the area, explains the difference between the two.
Understanding Auxiliary Heat
Auxiliary heat, or “aux heat”, is designed to support your main heat pump when temperatures drop outside. When your heat pump struggles to heat your home to the desired temperature, aux heat activates to provide the necessary boost. This secondary source of heat typically involves electric heating coils or, in some systems, gas-powered elements.
Encountering cold snaps that push your heat pump to its limits is not uncommon in this part of the U.S. Aux heat automatically kicks in when the thermostat detects that the indoor temperature is dropping below the desired setting by a couple of degrees. Once the home warms up to an appropriate temperature, the auxiliary heat turns off.
Keep in mind that the auxiliary heat mechanism must be in good condition to ensure it works when needed. A professional HVAC and plumbing contractor can assess your heating system to make sure it’s running as intended.
Recognizing Emergency Heat
On the other hand, emergency heat is something you turn on manually — a mode used when the heat pump fails entirely or the outdoor temperature is extremely low (usually below 30 degrees Fahrenheit). Emergency heat relies solely on the secondary heat source, which consumes more energy. Typically, one would switch to emergency heat only if the heat pump is not functioning or in need of immediate repair.
When To Use Auxiliary vs. Emergency Heat
The automatic function of aux heat offers convenience, providing additional heat only when necessary, thus optimizing energy use. Emergency heat, requiring manual activation, is effectively a last-resort option. Should you notice your aux heat activating more frequently or your emergency heat being necessary for extended periods, it might be time to consult with professionals.
