Heat Pumps? When to use Emergency Heat?

[@danilohernandez8829]

Thank you so much for your advice my heat pump it been working for almost 48 hours now and none stop and i saw your video and i turn it to emergency heat like you said and now its warming up the house Thank you God Bless you

[@aaronclark1599]

I just posted this on my Facebook today telling people they need to use the emergency heat when it's below freezing. Some technicians will say oh you're losing heat because you're taking out the heat pump which is a source of heat but people don't realize you're running two separate pieces of equipment at the same time when you could shut one off and just run the single one and have much better Heat

[@TaddyDigest]

I agree so true 👍

[@rogerknight2267]

My electrician being a man of experience and full of wisdom, advised me that if I was going to use a heat pump in our old house, I better invest in a secondary source of heat. That was several years ago. We had a wood heater installed just last year. It compliments our heat pump very well. Our energy cost year to date compared to the same period of time last year has dropped 25%. You can’t beat burning oak when it’s 20 degrees outside!! Thank you for the video. Very informative!!

BUT JUST LEAVE IT ON AUTO ALL WINTER SO IT DOESNT MESS UP ..SOMETHING IN THERMOSTAT OR SOMETHING ... IS THIS TRUE ??? _______ . To me during warmer days it wastes energy ...because even set at 72° ...it always comes on every once inwhile regardless really. ~~~ So during those times i liked to turn it off. Yes ?

[@Little_Bitz]

WELL, you just put me on to something here. I've never heard of a wood heater, but now I want one lol. Simply for the fact that I wanna smell that beautiful smell. Well, also of course because I wanna save some money too. Thanks for giving me something else to get lost down a rabbit hole looking up lol.

[@rogerknight2267]

@@JasongCLJ I leave my heat pump set on auto. Summer months the thermostat is set on 75, winter 68. The unit not only helps to maintain consistent temperatures but also controls humidity in the house. If you turn your unit off for hours or so, and then turn it back on, it has to work extra hard to catch back up.

[@plmpcharisma9686]

What are other secondary sources besides the wood heater?

[@billkunert7281]

I have a 2 1/2 ton Rheem installed last spring. Recently on a 25 degree day I was measuring 87 degrees at a register and it wasn't on aux heat. My system on aux heat uses one heat strip and 2 strips on emergency heat. The system will go into AUX heat when the heat pump can't keep within 2 degrees of the set temp. The installer advised not to use emergency heat unless the heat pump fails.

[@mrx01210]

Heat pumps can function well into the teens though .. our heat pump can keep up with no issues until about 10F then the auxiliary heat will start helping .. They also have a defrost cycle that prevents damage from snow / ice .. during the last storm in Arkansas the temperature dropped to -2F and the heat pump was still producing heat through the coils .. I had to remove the snow from its sides .. running costantly through a snow storm / freezing rain is actually a good thing and it should prevent the snow / ice from accumulating (within reason of course)..

[@TaddyDigest]

Very cool this is good information thank you for letting me know this information I will consider this And try to And try to evaluate for when we should turn the heat strips on Thanks for watching

[@jabba334]

Hello fellow Arkansas resident! You are absolutely right! I was concerned because my heat pump refused to cycle off but it kept the house at 72F and only occasionally used the emergency heat when the temperature hit -2F that one morning. From what research I did, the long run times are normal when the temperature outside goes below freezing. As for the snow/ice you are right again. My split unit is on the leeward side of the house so I didn't have to worry about snow piling up around it, but it's a good idea to check anyway. Overall, I was impressed as this is my first heat pump and didn't know what to expect. So, despite running so much, my final electric bill for February was $130 and will probably go down before summer. Nice!

[@a.milligan9165]

Thank you. I'm new to a heat pump and didn't understand why it ran so long at time during below freezing Temps. I actually bought a new digital thermostat thinking the old one was malfunctioning.

[@chris2790]

@@a.milligan9165 Why would you think that if the temp in the house was just barely being maintained? It would be one thing if it kept running and the house was getting hotter. A thermostat's job is to maintain the set temperature within .5 degree either way and will run the equipment as long or as little necessary to do that. If you're new to something, the internet is your friend. ;) I was going to say google is your friend, but that's not been true for some time now.

[@chris2790]

Define "function well" and "no issues". Sure, it'll provide heat, but at ever increasing cost until you reach the 2 or 3 times mark above normal of the emergency heat alone. I consider my electric bill in really cold weather to be a significant issue. :D

[@jjblueflame]

Thank you for this video! My apartment maintenance man tried to run the okie doke on me regarding if my unit was working correctly. It was around 40 degrees here in Texas, and my heat was staying on constantly and just blowing cool air. I was trying to keep the temp inside at 76 degrees. The thermostat said Aux Heat, but the air out of the vent was still cool. So I turned on the emergency heat (not knowing what I was doing), and warm air started flowing. However, I turned it off out of fear I was causing an issue. I told my apartments something was wrong because the unit should not be blowing cool air when in normal heat mode if the temperature outside is in the 40s. The maintenance man said I should use the normal setting if I am trying to heat the apartment by several degrees, then use emergency heat if I am only trying to warm by a couple of degrees. That doesn't make sense because the normal setting doesn't raise the temperature by one degree and continuously runs. Needless to say, I am moving in a couple of weeks.

Had a Lennox installed last month after having a Trane for 15 years. Tuesday the compression stopped working, and we were cold for a few hours until the tech told us to use emergency heat. The Trane never stopped, nor have we had to use emergency heat before. I was told that the Lennox compressor will automatically stop in very low temperatures. I don't like the idea of using emergency heat and having a high electricity bill.

[@RyanSymes-tv9ct]

We just had a cold spell below 0. When I came home from work I noticed my outside unit was not running. I switched my thermostat to emergency heat for a few days. After outside temps warmed up, I switched back to heat (through heat pump) and the outside unit still would not run. After turning off the thermostat for a couple hours and turning it back on the outside unit started to run again. Have you ever heard of this happening? I was getting power to my outside unit and the caps were good. The contactor was not pulling in during this time.

[@EricV485]

I noticed I never have to turn on the emergency heat manually…it just does it itself. I could tell recently here in NC when the temp dropped to between single digit lows and below 25 degrees for highs for 3 days straight and my energy usage nearly tripled…the heat coming out also felt more radiant than when the heat pump normally runs

[@JetSettingBotanist]

Most heat pumps will automatically switch to aux heat if needed. No need to switch just because it’s below a certain temperature, at that point you’re just killing the efficiency of the heat pump and might as well just run a regular furnace and a straight cool unit. I have a 3.5 ton Payne ac/heat pump that chugged along all the way down to -10°F before automatically switching over to aux heat only. It would occasionally kick on the aux heat above -10 when needed. It’s listed as emergency heat for a reason not something to constantly use because it’s a little frosty outside. I would recommend to anyone to use the heat pump on regular heat setting unless it’s not maintaining temperature. Then check your unit for ice buildup and at that point switch to emergency heat and get the unit defrosted or call an HVAC tech. Maybe some units are different but I can’t imagine a unit that needs to be manually switched to EM heat at 30° or colder would be installed anywhere outside of south Florida or Coastal southern California.

[@TaddyDigest]

Absolutely I agree Brad great comment with good information Thank you for watching and commenting Emergency heat has to be used here in Tennessee when it gets real really cold and there's ice build-up on the equipment which can damage the equipment

[@dylanclay2741]

As long as you have a newer thermostat then yes it'll automatically switch. However on older ones like mine you have to manually switch. So know which type you have

[@johnjohnson5489]

Hi Tad - great video. I have an Ecobee thermostat that has capability to bring in heat strips via (2) stages. My stage 1 is 12 KW and stage 2 is 24 KW. This past month has been very cold so we have used heat strips a lot but here is my problem that you may have seen. Stage 1 - provides cool air at full currents draw. Stage 2 provides warm air at fu current draw. Question - can a heat strip have fun current draw but little or no heat output? How can one check this as these heat drips are full enclosed.

[@kevinadams9468]

I am listening to this and it never ceases to amaze me... I live in SW Nebraska, far from the areas I would think are ideal for a heat pump. I shut my older unit off last year at around 28 degrees. This year, after having it serviced in the fall I tried to see what it could do in a normal winter, and so far we have gone down to 9 degrees. The heat pump cycles on and off constantly, air conditioning my small house while trying to warm 'Joe Biden's Choice of HVAC appliances' (lol). Basically, at anything under 25 degrees this thing is a dumpster fire. I spent two hows carefully de-icing my heat pump today (we had 60 mph winds and blizzard conditions, so I went out to check on it. It is easier for me to run a couple space heaters and avoid the AC effects, or just turn on my propane heater. It keeps the whole living area at 68 on the lowest setting. We get down top -20 a couple of times each year. why would anyone install a heat pump as a primary heating unit?

Imagine, if you will, a heating system that doesn't work when you need it most.

[@canuckrunamuk23]

I'm using a large Mitsubishi Zuba Central Heat Pump which was installed with a 5kw Aux Heat strip. While my Heat pump is rated to perform in well below freezing temps...a large concern for me is during large winter storms which may result in a power outage. Depending on how long the power is out for it is nice to know during the outage I can fire up my backup generator and switch the heating system to emergency backup heat...during this time I definitely have a tarp or two ready to wrap around the outdoor air unit to prevent snow/ice buildup. I make sure the outdoor unit is off at the breaker switch and to do a thorough inspection before switching the outdoor unit back on when power is restored.

I did learn something. Appreciate that. It would have been helpful to another segment of learners had you been able to use a nest thermostat to give an example. Hopefully you will get to and answer my question though. So what I want to do on my nest is set the thermostat to use auxiliary heat when the temperature falls below 30 degrees. That can be set up on the nest. Mine came already programmed at 50 degrees. So I understand that. Not sure why it is programmed to begin at 50 degrees but it seems unnecessary when the outside temperatures will still allow the pump to heat your home without needing the auxiliary mode. If I’m right about that and I set my auxiliary heat to kick in at 30 and the temps go below that should the home get heated the same as when the auxiliary isn’t being used? The reason I’m asking is as with everyone during this really cold weather it got down to 8 degrees at my home. The auxiliary heat was being called for by my nest thermostat but it would not heat the house pretty much at all that first day. My inside temp fell to 59 and stayed there for hours. Is there something wrong with my heat pump or is that normal? I hope I was clear and you get a chance to answer. Thanks

Good video to educate people. Heat pumps as the only source of heat suck for many climates/areas that they are installed in. I have a two story home with two, located around the Washington DC area. We regularly see temps in the mid to low 30s and even below. Right now it's 20 deg F outside this morning. Thankfully, I was able to install a pellet stove when I moved into this place and that does a good job of keeping the runtime of the heat pumps down to around 50% on the coldest of days. I need to tweak my basement air return which should reduce it even more. Our electric bill stays below $200/month this way, Otherwise, I'd expect it to be well over $300, maybe close to $400. If I can get pellets at a discounted price I'm guessing my cost is lower than heat pump alone. At normal pricing, it's probably comparable, but with wood pellets at least I have more comfort and when paired with my generator, heat during power outages. Sadly, it's going to get more and more expensive to heat our homes as the false prophets of climate doom push for more and more "green" energy. Rolling blackouts are gonna be fun too. Don't worry about them though, the elites always flourish above "the people".

Glad you got warm heat now good deal

[@Gnomeinyourpants]

Such wow! If you have a PROPERLY installed heat pump, thermostat, and air handler, you shouldn't need to ever worry about these things. The Bosch unit I have has sensors installed on it so when it detects ice, it will automatically call for the heat strips to turn on, reverse the compressor and thaw itself out, also known as a hard defrost. In a normal defrost, it just reverses the compressor and uses existing indoor heat to thaw itself out, typically at the end of its cycle.

I live in Arkansas and we just had that winter weather blow through. The night it was rolling in, we had rain, then sleet, then rain again, and it went back and forth for a bit before eventually changing to snow. When the temps were just at freezing, my unit was making a weird sound like it was not balanced. I new it had to be the fan just from the sound it was making. I shut it down, let it sit for a bit, and then set the heat back to it's normal temp and let it fire back up. Was fine after that. I am assuming the rain helped flush off whatever ice did accumulate on the blades, making it unbalanced. I thought for sure my unit was broken. It warmed up the next day and melted anything that was on/in the unit, and it has been running normally.

FWIW, modern heat pumps can handle cold weather much, much better than they could even a decade ago. I recently replaced my gas furnace with a dual fuel heat pump, figuring I would run the heat pump down to about 35F and then switch over to gas. Nope. Heat pump has zero problems keeping up down into the 20s. It started to run a lot at about 15F but was still keeping up. So I am barely using gas now, saving a bunch of $$$. Going dual fuel instead of just gas is going to pay for itself in just a few years.

During defrost mode , heat strips come on as well right? This is where I get confused. I’ve been hearing different purposes for them such as what you mentioned and that for emergency, they will ONLY run if the compressor fails and they are ran as a back up. But what about during defrost or supplemental (running with the compressor?) I’ve been in the trade for 7 years but never had an opportunity to install heat strips or rough them in (high voltage wires) so I’m having to research and try to learn so I don’t make a mistake once I come across it. I’ve installed heat pumps here in AZ but winters aren’t bad so there are a lot of heat pumps with out heat strips

Why be concerned with ice freezing on the heat pump when all of them go to auto defrost, thus kicks on the AC for a few minutes which is used to defrost the unit..Everything i have ever been told or read, says to use aux heat to help bring the house up to temp when the heat pump struggles. Using Aux heat is not to defrost the unit or that is not what it was initially designed for. Actually you want to discourage using aux heat unless absolutely necessary. No one wants a sky high electric bill. It's extremely inefficient and it drinks electricity.

[@TaddyDigest]

Hey Jeff great point I really appreciate this comment. The reason I am concerned about ice freezing on the unit is because sometimes the ice will freeze over the outdoor fan or freeze to the blades This ice freezing on or over the unit can cause damage to the unit

Hi Tad, It was below 30 Degrees F in New Jersey yesterday and my Heat Pump Compressor was running continuously. I switched ON Emergency Heat from my Google Nest E Thermostat. My set temperature of 72 was reached in about 30 minutes and the compressor stopped running. You mentioned that the Compressor will stop right away if I select Em Heat on the Thermostat. Is this correct? If yes, I will be using less electrical energy in Em Mode by not running the compressor than in the Normal mode when the compressor will be running along with the Aux electrical elements. I had misconceptions about Auxiliary Heat and Emergency heat being two different things. You clarified that they are the same electrical heating elements within the Air-Handling unit. I tried to understand this concept by reading tons of literature from Google Nest and other sources but could not understand. Thanks for your video which clearly explained everything that I needed to know. Brilliant!

[@TaddyDigest]

Yes, the compressor will stop as well as the outdoor fan motor. Glad to hear this. Thank you for watching my friend.

The below table outlines the cost differences of normal heat pump use a=in 30 degrees F weather for one week versus one week of use in 10 degrees F weather with the emergency heat in use for 12 hours per day to keep up with demand. Cost Breakdown Normal Operation at 30 Degrees for 1 week Emergency Heat Operation at 10 Degrees for 1 week Watts per hour: 3000 watts 3000 watts + 15000 watts Hours use per day: 12 hours 24 hours + 12 hours Number of days: 7 days 7 days Total kWH: 252 kWH 252 kWH + 1260 kWH Cost per kWH: $0.13 $0.13 Total Cost per Week: $32.76 $196.56 As you can see, there is a severe increase in the cost of $163.80 per week when the emergency heat is in use in extremely cost weather. might want to consider the costs of emergency heat

I have a Honeywell thermostat on a Maytag heat pump system I was told to let the thermostat control the heat strips doing it manually could actually damage it is this true or false let the thermostat handle the emergency heat system

[@catfish500mark9]

I timed how long my heat pump ran vs heat strips.The temp was 27-28 degrees.The heat pump ran about 20 mins to keep house at 69°.With the heat strips it ran 6-8 mins to keep my house at 69°.So which is more efficient?To me it seems like the heat strips would be even though they're pulling alot more current.

The heat strips pulled double if not triple the current So factor that in

For some reason when I turn the heat on during the winter it blows out cold air and I have to turn it on to emergency to heat the house. it uses way more electricity using the emergency resistance heating so im trying to figure out why its blowing cold air when the regular heat is on. I thinking it might be the reversing valve on my outdoor unit is stuck in the cold position?

[@TaddyDigest]

Yes it could be that or it could be a few other things.

[@Anonymous-zo3uu]

There's rarely a reason to run emergency heat, hence the name. However, not maintaining the system to the point the outdoor unit is full of dirt and freezes into a solid block of ice is a good reason. Otherwise, you really shouldn't ever deliberately turn off the outdoor unit. Most modern systems are still more efficient than the heat strips at -5, but they need to be maintained and kept an eye on at least a little. I see you made this video less than a week before the polar vortex, so while I completely disagree with you on when to use emergency heat, it was well timed and probably legitimately helped some people.

[@TaddyDigest]

I agree with you and it's better to run the heat pump than the heat strips even in really cold weather But yes I did make the video so that people that seen their unit frozen solid block of ice that did not defrost or thaw that they might have a chance to turn it off and save from creating damage thanks for commenting and watching 👀 🙂

[@chris2790]

Good to know, but more efficient down to -5 isn't much solace when you're paying up to 2 to 3 times as you approach that point. Heat pumps are installed in climates they shouldn't be, at least when they don't have a secondary heat source like an oil or gas furnace. Depending on fuel costs though, gas isn't that great, especially if we are talking Propane over piped gas in cities.

Not really. My Goodman is 3 years old along with house that was built in 2019. It was just serviced again in September. House is about as weatherproofed as I can get it. Heat pump still struggles below 15 degrees during the night. Need the heat strips.

[@milesruby3271]

My unit automatically switches to auxiliary heat when it gets super cold and heatpump isn't cutting it. There's light on my thermostat that turns on when it switches over. There is still a switch for emergency heat, do I still need to switch it over to emergency? We just moved into a new house and I am not familiar with this system. It is a older Trane model. The heat is working no trouble keeping house warm, just don't want to damage anything out of ignorance. Thanks!

[@TaddyDigest]

yeah for sure switch to em heat to keep outside unit from getting damaged

[@nathanbrown5099]

I would monitor the outdoor unit to see if it gets ice on it obviously keep it clear of ice and snow and you’ll be perfectly fine almost all thermostats know when to turn off the heat pump if it can’t keep up via temperature differential or a time constraint

[@ibnormal71]

I got advice from a maintenance man who was in charge of two apartment complexes. He had told me I should switch to emergency heat when it was 35° and below. Since I've done so it's been warm in the house and oddly quiet. The outside unit runs a lot less, and my electric bill is not heart attack threatening. I had the idea to run it on auxillary anyway just from luck and instinct. One day recently I put my hand up to the register in the kitchen and felt cold air coming through. I popped the thermostat on to emergency heat and put my hand up to the register again and the air was hot. To sum: the pump runs a lot less, maybe half the time than it did with emergency heat off. There isn't any growth of ice showing up all over the heat pump. Hot air comes out steadily, not sporadically hot and cold. My bill is manageable. It was $80 less than it was this time last year. Now, it could have been warmer out last year, I don't remember the temp. But that heat pump was running constantly a year ago, I do know that. And I have a Frigidaire, nothing fancy. This worked for me, anyway. I suppose it varies for every individual, I dunno. Hope it helps

[@cranbers]

Its crazy how so few people know about Heat pumps in the US. I have a heat pump and its cut off is automatic at 15 degrees. Every heat pump is different some can go down to 35, some -15 some 17. So don't just take this guys word for it he's talking about this york model, some thermostat's won't even allow you to manually go into aux heat mode they will just do it automatically if your heat pump is running and the temp in the home keeps dropping. It might be 2 degrees below set point it switches to aux heat. This is why the third party smart thermostats are so nice example would be the nest thermostat. This works with heat pumps and aux heat, you can set all sorts of options to save you money. A heat pump will always produce some heat even down in the zero range but the question is will it run so long and produce too little heat to keep you comfortable. That's when aux heat kicks in. I have a Daikin VRV life system, it switched over at 15 degrees and went to back up heat which is propane.

Wow I had no idea when to turn on emergency heat, I had a brand new HVAC installed three years ago and the installer never told me this. It got down to 24 last night and my unit iced up big time and I had no idea why cold air was blowing in the house, it was brrr cold in my house last night, got down to 49. But in the morning I went outside with my hot pressure washed and got rid of all the ice. Right now it's 28 and I went outside and looked and I can already see where it's starting to form ice and I'm sure it will only get thicker as it gets later in the night. I'm going to activate the emergency heat since seeing your video, can it stay on all night?

I had an older heat pump that my folks had put in, but it had to replaced last year and the new one is not working the same way at cold temps. I was told nothing about using emergency heat when this was put in. I have spoken to the man who put it and he has told me two different things on two different days, and I am confused. I now know when it is going to be below 0 that i need to put it on emergency heat, but this time when it was put on it, it was dropping and despite my having it put on 72 degrees it was only reading at 64 degrees. I had a local company come out and check it because the man who put it in was not answering his phone and they replaced the filter, and it came up to 68 degrees, but by the next morning it was down to 64 and it stayed that way all day. My house was very cold and until my sister brought me a space heater did the indoor temp rise. It never got up to 72 until the day it was above 20 degrees. I did not have this trouble before this cold snap came along - I do not understand why it is not working properly since the frigid weather. Does this mean there is a problem? Right now I have had it on heat pump and it took it over 2 hours to come up to the 72 setting, but it has been running since I turned it off emergency heat and I am wondering if that is correct. I just do not feel the man who put it in wants to come down and check it out. I am trying to understand this new equipment and never did my parents have to deal with this - they always had good heat from the old unit and I did until it had to be replaced. I was never told that this one would not be able to maintain heat below 0 and that it should be turned onto emergency settings...apparently it has a warranty, and I never knew about that either! I do not feel I was told what I needed to know. Can anyone help me understand?

[@Thisishard2333]

Finally. I’m sitting here in Nc. It’s 30 outside. Inside 58 degrees.Everyone here says don’t use your emergency heat. It’s like paying for auto insurance and being afraid to use it. I shut my heat off because the pump will run and never shut off .We wake up just because it’s so cold inside.Once the sun comes up even if it’s still freezing outside the pump starts heating up the house like toast. My question. Can I just turn on emergency heat just to get the chill out say 5 minutes? Then switch it back to normal? And when it’s on emergency heat , will the thermostat work normally turning the heat strips on and off automatically to maintain temp?

[@TaddyDigest]

Yes you can turn it on for five minutes and yes it will work normally.

[@The12stonesfan]

here in Louisiana, it dropped to 10 degrees during this cold blast and for three days straight stayed below 32 degrees, heat pumps around here struggled to keep up with the extreme cold and it was a mess so many calls. That's why my company has recently started telling customers upfront when we they are choosing a new unit that if you pick a your heat pump, it will likely not work when it gets to 32 degrees or more and advise them to use emergency heat. But of course nobody does nor do they understand what a heat pump actually is. I don't care what you say, when it gets below freezing around here all hell breaks loose and people wondering why their heat pump can't keep up. EDIT: a lot people don't factor in wind chills/feels like temps so really even at 32 degrees your heatpump can have issues. Even the new ones we install... even though many people would disagree and think a heat pump can just fare well in extreme cold, which I would say is disproven in many cases, not all.

I have a high efficiency hvac package..do i still turn it on emergency heat, or leave it on regular heat under the temperature under 30 degrees..Thanks

[@FrostHVAC]

Higher efficiencies are able to handle it. Below 32F is when your outdoor coil will start to freeze [because condensation created is below the freeze level for water], however it will still function properly, it may lose efficiency. That's the only thing you will notice, it'll take longer to heat the house, heat pumps take the heat of the outdoor air and discharges it inside the house. However once it reaches below 0 in outdoor temp, then your heatpump will become inefficient since there's no more heat outside to take in. Typically your thermostat, or unit will be smart enough to know when to run auxiliary heat when needed. [T-Stats typically have a setting within them that'll enable auxiliary heat when needed, like if the unit runs longer than usual, temp different of 2 degrees or more, etc].
