If you’re new to a home that has a heat pump system, look to the thermostat for more information. It may have a switch on the front, or its digital display may show an emergency or auxiliary option in its settings. If you don’t see either of those, the pump was likely installed without auxiliary heat.4 days ago.
Do heat pumps come with auxiliary heat?
Heat pumps have two units—one inside your home and one outside. The inside unit contains a coil for standard heating and electric coils for aux heat. The outside unit, called the condensing unit or “heat pump” is needed for standard heating but not auxiliary or emergency heating. This is where aux heat comes in.
How can I tell what type of heat pump I have?
How to tell if you have a heat pump? The best way is to check your outside system; there is usually a label that specifies if it is a heat pump or an air conditioner. If no such designation exists, Google the model number and brand name.
What is the difference between auxiliary heat and emergency heat?
Auxiliary heating turns on automatically to help heat your home more quickly if the temperature drops suddenly. The emergency heat setting has to be manually switched on and should only be used in temperatures below 30 degrees.
Can you turn AUX heat off?
It’s, unfortunately, not possible to manually shut off auxiliary heat. But it only turns on when your home needs warmth fast. So if you don’t let the temperature drop quickly in your house, it won’t come on.
What causes auxiliary heat to come on?
Aux heat will kick on when your heat pump cannot deliver enough warmth to heat your home. Typically, your heat pump will energize the auxiliary heat strip inside your secondary heating source to help reach its set temperature faster.
Does my heat pump use an O or B wire?
Your heat pump uses O and B wire. O wire shift the reversing valve from heating to cooling while the B wire does the opposite (Cooling to Heating). The O and B wires are easy enough to spot because they are ‘Orange’ and ‘Dark Blue,’ respectively.
How do I know if I have a furnace or heat pump?
If there’s a gas line running into your heating system, then you have a furnace, because heat pumps only use electricity. If you have auxiliary or emergency heat, then you have a heat pump. Furnaces don’t need auxiliary heat because they work just as well when the temperatures drop below freezing.
How do I know if my central heat is gas or electric?
There’s usually a small window located on the front of the heater. Look in the window. If you see a blue flame, it’s a gas heat exchanger. Other units will have a small metal panel that’s easy to remove.
Is Aux heat expensive?
As we mentioned above, AUX heat usually costs up to 50% more than heat transfer, which means if your system is running on AUX heat when it shouldn’t be, your heating bill is likely going to be a lot higher than you’d like it to be. Our suggestion would be to reach out to a professional as soon as possible.
How often should AUX heat come on?
When should my auxiliary heat come on? When outside temperatures drop below 40 degrees. While undergoing the defrost cycle. When there is a 3 degree difference or more in the current temperature in your home and the thermostat setting.
When should you switch to emergency heat on heat pump?
It is used when there is something wrong with first-stage heating (the Heat Pump itself). In other words, if you notice your house is cold and it isn’t heating properly and you went outside and noticed that a tree fell and crushed your heat pump, that would be a good time to switch to Emergency Heat.
Why does my thermostat says auxiliary heat on?
When you see the “aux” heat indicator on your thermostat it means your heat pump needed some help reaching the desired temperature. It turns on automatically when the temperature falls about two degrees below the desired setting and turns off automatically when the target temperature is reached.
What is Stage 2 auxiliary heat?
First-stage auxiliary heating for heat pumps and multi-stage furnaces; provides supplemental gas or electric heat when the heat pump cannot meet demand. Stage 2 Aux Heating. Second-stage auxiliary heating for heat pumps and multi-stage furnaces.
How much more expensive is auxiliary heat?
What is this? It will vary depending upon your energy provider, but typically auxiliary heat is up to 50% more costly than conventional heat. Auxiliary heat is different from your average heat source because instead of using a heating pump, it uses heating strips.
How do you know if your emergency heat is on?
Emergency Heat Mode Comes with a Red Indicator Light: When you turn your emergency heat on, you will see a red indicator light. This light tells you that your HVAC system is now operating in emergency mode, and it will remain on until you deactivate your emergency heat.
What color is the OB wire?
It’s usually blue, but it may also be black, brown or purple. The O or orange wire connects to your heat pump (if applicable).
What is B on heat pump?
The O/B terminal is for heat pump systems and is used for the reversing valve. If the “B” option/position is selected the reversing valve defaults to the cooling mode. It is extremely import that the correct mode is selected. If you get it reversed the heat pump will cool in the heat mode, and heat in the cool mode.
What color wire is heat on heat pump?
Blue wires are for heat pumps. This wire connects to terminal B on your thermostat.
