Basically, auxiliary heating Use resistance heating to heat your home. Since resistance heating is far less efficient than a heat pump, you only want to turn it on when necessary. … retrospective, auxiliary or emergency heating should only be turned on when the outside temperature is below freezing.

Wouldn’t it be bad if auxiliary heating came along?

AUX cooling is not good?short answer No. In fact, auxiliary heating is a key mechanism to keep the heat pump functioning properly when the outdoor temperature drops. Since this type of unit is different from a furnace, it gets cold.

Why does auxiliary heating occur?

What does this mean for my thermostat?If your auxiliary heat indicator is on, it means Your heat pump needs a little help to reach its target temperature settingAuxiliary heating comes from the same heat source as emergency heating, but auxiliary heating works with your heat pump, so it is less expensive than emergency heating.

Is auxiliary heating more expensive?

Auxiliary heating can handle more extreme temperatures because it uses electric heating strips.Unfortunately, this means It is more expensive than conventional heat provided by a heat pump. . . Although a gas furnace is not as efficient as a heat pump, it is more efficient than a heat pump that uses auxiliary heat.

How do I stop my auxiliary heat from showing up?

Tips for Avoiding AUX Overheating Problems

1. Schedule preventive maintenance every six months.
2. Regularly clean the area around the outdoor HVAC unit.
3. Keep pipes and vents clean.
4. Do not use emergency heating settings for normal heating.
5. Clean or replace the heat pump filter every two months.

Are emergency heat and auxiliary heat the same?

Auxiliary heating on automatically It can help you heat your home faster if the temperature suddenly drops. The emergency heat setting must be turned on manually and can only be used at temperatures below 30 degrees.

Do the heat pump and AUX heat operate at the same time?

To allow heat pump/auxiliary heat to operate simultaneously: If you select Yes and there is an auxiliary heat source, both the auxiliary heating and the heat pump will be turned on. … if the set point is not reached after 2 hours, the thermostat will turn off the heat pump and invoke auxiliary heating to reach the set point.

Why is my heat pump blowing cold air?

is thawed.To protect the outdoor coil from freezing in winter, the heat pump passes a Thaw every hour or so They really blow cold air in it. This defrost period lasts only a few minutes and won’t affect the overall temperature of your home.

Can I turn on the heat to defrost the air conditioner?

What is the most common form of auxiliary heat in a heat pump?

Most auxiliary heating equipment is resistance heating coil. A few are finned heating elements. Either way, heat pumps turn on when they can’t draw enough heat from the outside to meet the thermostat’s set temperature.

How long does the auxiliary heat run for?

Auxiliary hot operation continuously Even if the temperature is higher than 40 degrees.

What does AUX heat on a thermostat mean?

Heat pump with auxiliary heat (air or geothermal)

W2, AUX and or E (Emergency situations) Wiring will normally go to the ecobee3 W1 terminal. The ecobee3 manages auxiliary heating through the W1 and W2 (if there is more than 1 stage auxiliary heating) terminal outputs.

At what temperature does the heat pump switch to emergency heating?

Emergency heating, also known as « auxiliary heating, » is the second stage of heat the thermostat operates when the temperature is too low for your heat pump to extract heat from the outside.Emergency heating is usually triggered when 35°F and below outdoor.

What is auxiliary heat usually used for?

Your auxiliary heat supplements the heat pump’s hot air.Most auxiliary heat sources are electro-thermal, using an electrical coil similar to the one in a toaster. (Some heat pumps do rely on natural gas or oil, but we’re adding electric heat here, although the principle is the same.)

Is the heat pump running all the time?
