@ 6:57 it looks like it is in A/C mode (snowflake symbol) above the set point temp at the top but when he cuts back the light is pulsating orange which should indicate heat mode so I am not sure. Wave 2 manual: cdn.solarpowersupply.eu/files/(EN)%20Manual%20Ecoflow%20wave2-20230419.pdf The only theory I can come up with is the hose is a tight L behind the curtain and it throttles it which could explain the lower Wattage with the hose connected? Heat Pumps do work even in negative degrees Fahrenheit

[@jw3843]

I am glad someone finally tested it without the intake hose on video. Just as I thought, it heats better without it at cold temps. It also helps to insulate those hoses. That is a lot for an AC and I would not be willing to pay that for it. I would save a bunch and just get a window unit.

[@BrandEver117]

The website does list the lowest operating temperature as 41°F. Which is still useful in certain places (Where I live it only gets to freezing a few times a year but is 40s-50s most of the time), but definitely not in harsher climates. There are cold weather heat pumps that can operate well under freezing temperatures but idk what they do to make them capable of that.

[@ryangassxx]

Tyler, I love you bro but sometimes I think you mess up on your experiments.. 😅 I’m relatively certain that the hoses are for the AC function side of things. Why would you pull in 20 degree air from outside to heat and warm the indoors?

[@nevernever2002]

They are for the AC yes. A traditional heat pump uses refrigerant to move BTUs in or out of spaces. You can literally make your own version of this thing by getting a 150 dollar window unit and just flipping it around in the window lol. Or a portable unit; duct tape some cheap insulated tubing to the intake and the supply air side and leave the vent tube for the hot side off.

[@domin727]

Heatpumps draw heat energy from the environment and this process uses energy not the conversion of electrical energy to heat. So its actually quite realistic to get about 3 times the energy you put in out in heat, because all the pump does is "concentrate" the heat in a smaller volume of air so to speak. To manage that however the thing needed to draw that heat out of the outside air and put it into some air inside and afterwards geting the air back out again. That means you need 2! hoses to the outside, intake and outtake not just one. You either let the thing draw heat from the inside or blew the cooled air to put outside right back in. For having next to zero effect...

[@TinyGoHomes]

Im working on a build for a plug in heater furnace box. It has a heat exchanger built in and a filter you can change. The heater runs on a thermostat plug and the fresh air fans run 24/7. Brings in fresh air, exchanges it across the exit air and is heated before being fan forced and directed to the floor. I hope to make a prototype soon and begin testing. 👍 I also have a cool idea I’m way too busy to even look at where you take a small iron stove and make it so you can burn multiple fuels. Attachments to burn propane, diesel, oil, wood, pellets etc. all you gotta do is let it cool down and change the attached pieces.

[@JacobBarnett-qn4uf]

The reason for it using less energy with the rear inatke out the window, is down to the lower temperatures decreasing the suction pressure of the compressor which means it requires less power to "compress". As soon as the inatke is room temperature, the pressures starts to increase, it becomes harder to compress and will increase power consumption👍

[@eyebrows4]

I came to the comments hoping I wasn't the only one that understands HVAC! You have slightly restored my faith in humanity. To be honest I was sad to see Tyler obviously researched BTU but didn't do the same for heat pumps and was so confident in the limited understanding he had. I'm not bad mouthing him, I understand we and he can't be experts on everything. I still love the channel and will continue to watch but I was genuinely excited for this video and sadly let down by he's presentation.

[@averyalexander2303]

That's exactly what I was going to say in addition to the higher discharge pressure with a warmer inlet air temperature. AC units behave the same way drawing more power as either the inside or the outside air temperature increases for the same reason. Inverter driven systems are a little different because they may run the compressor at less than full speed in heat mode when the outside temperature is higher and then run the compressor faster as the outside temperature drops to maintain (or at least try to maintain) the setpoint.

[@eyebrows4]

I hope he sees our comments and either edits the video or makes another addressing theses things.

[@JacobBarnett-qn4uf]

​@@eyebrows4 yes very true, although i did have to search up what a btu even was. I'm british as well🤣...

[@JacobBarnett-qn4uf]

Well, inverter systems are more benefical energy wise as well. While being able to maintain a tighter differential, they dont have to kick in and out on full power all the time. They'll just hum away using next to no power. I did find the companys heat output calculations strange though, but thinking about it a little more. In the video, the heat energy thats being added to the room is also being used as the inlet air to boil off refrigerant, and then exhaust outside. So i guess the figures would match up in perfect conditions🤔

[@ModernGentleman]

Omg I heard heat pumps and had Technology Connections flashbacks😅

[@powerstroke01]

Same 😂

[@Hudson316]

He also hated portable AC units so this is a twofer

[@madeintexas3d442]

The reason why it can get more BTUs than the capacity of the battery is because it is most likely a heat pump. They can get up to 5x the efficiency of a regular resistive heater because it is just transferring the existing energy in the environment instead of adding additional energy. Edit: Probably the reason why the heater didn't work in the first part was because it wasn't vented. If it is a heat pump it will blow hot air out the front and cold air out the back creating an environment that is the same as what you started with. If you can vent the waste air to the outside you would get better results.

[@lifequest7453]

I thought I heard you say this is a heat pump, is that right? If so, heat pumps heat very slowly. It takes time to get a room up to temp and the heat you feel from the unit feels cool, but they can heat a room. In a heat pump heated home, the amount of air flow makes a huge difference in the temperature change. When Mine was installed, they told me to open all the air vents, because the more air flow you have, the better it can heat your space.

[@FUGP72]

So...he didn't read the directions. NO heating system is going to be able to heat 20 degree air to 70 degrees in one go. The whole point is recirculating the air. So every pass through the machine, it is heating slightly warmer air. Air conditioners do the same thing. They RECIRCULATE the air. They don't take the 90 degree outside air and magically cool it through the freon coils in one pass.

[@RoadKing05FLHR]

The air that's circulating outside is separate from the inside air.

[@grayrabbit2211]

Eh...actually, most heat pumps and air conditioners can. My central system heat pump is almost 20 years old and has a 28-33F degree temperature drop across the inside coil in cooling, 35-40F rise in temperature in heating mode. I can vouch for 20F as the coldest we ever had here was 24F, but at 24F it was able to maintain 72F inside.

[@375Cheytac]

I would agree with you, however you said heating system… a 400,000 btu propane furnace can absolutely heat a 4000 sq foot shop to “un-livable” in no time lol

[@ryanrobin12]

That’s not how it works. It’s physics and pressure. Air, however hot, can be compressed enough to lower the kinetic energy and slow the air molecules, cooking the air. All air conditioning systems like this operate on these fundamental principles, and which is why they have Freon and compression systems

[@pdx_painter]

1) Trying to make a piece of equipment do something do what it wasn’t designed to do and then saying it doesn’t work is dumb. 2) Not following the instructions and complaining about it is also dumb. 3) comparing to a purpose designed electric space heater is an unfair comparison. If you have full time access to 110v power, buying the EcoFlow to heat (not its primary purpose) is not a wise decision. If you are running in an of grid environment, like an RV or vanliving, and you need battery/solar powered AC, this is the perfect solution, and you get the added benefit of heating if needed, but most of those customers would know that there are much better solutions for just heating. Bottom line is that nobody that knows anything about what the need is buying this for heat.

[@Bound4Earth]

Did you not test the AC part?

[@Jake-p9p]

This is just my opinion. I feel how it is set up is the correct way but it is too cold outside. This unit basically puts the outdoor and indoor unit together if you compare it to a regular heat pump that has half the unit outside and the other inside on your wall or part of your furnace. The hoses venting outside are keeping what would be the outdoor part of the unit outside. If you disconnect the intake you will just be throwing your heated air back outdoors through the exhaust and creating negative pressure. Now your unit will be pulling cooler air from under the door, around windows, etc.. and be throwing your heated air out. Myself I wouldn't disconnect the intake hose and would set it up just like in the video and like it shows in the instructions. JMO

[@jenkinsjarrod]

Heat pumps lose efficiency once outside temps fall below 40 degrees F down to 25 degrees F. Below 25 degrees F, they become ineffective as there is not enough residual heat in the air for it to pull, hence why when installing a heat pump, the tech will install an auxiliary heater indoors in order to heat the space once temps become too low. There is an actual thermal switch in the external heat pump that will switch the unit over to aux heat once temps fall below the threshold. Auxiliary Heat will turn on automatically when heat can no longer efficiently transfer heat from the outside air to the heat pump.

[@AquaTech225]

Just turned the heat in mine on. 66° room air it’s blowing out 100.8° air. It’s not really cold out. But when it was in the mid 30’s outside its was still able to put out atleast 20° delta in temp difference. I believe ecoflow uses a not so low number for outside temp before it’s not as efficient. But it definitely worked when it got in the 30’s. The AC part in the upper 80’s an humid as hell. Depending just like the delta on heat. The fan speed. On low it’s about a 20° degree delta. Speed two it’s like 16-17 speed 3 is like 15-16 and turbo is like 14-15° difference. These things are made for off grid/power out and to be able to run off of battery banks aside from the attachable one. A not be a huge energy draw. I forget the square footage they claim but these things are for tent sized areas. Not home sized rooms and big duel rear axle rv’s ect. So it it don’t work for someone. They don’t know how to work with its limitations and maybe do different things to capitalize on its ability.

[@kasualhex64]

This thing is awesome in a small space like tent or vehicle. I found that it is recycling the air sucked through the front. So at initial heating/cooling of your space if you feed it cold/hot air it will will help it get your space to your temp way faster, then you can stop feeding the air and it will do fine maintaining the space temp.

[@grayrabbit2211]

Did you watch the video? It failed to heat the room. After 1 hour it was 1 degree cooler

[@paulineh301]

The measurement of BTUs is mote applicable to how much energy is transferred from the intake air to the output air. If you are taking 20deg air and heating it to 60deg that is a considerable heat input. Tyler is being overly simplistic. Not reading the manual to find out the operating parameters of the device is also dodgy in my opinion... At least he tried it with the more logical approach of using one hose to exhaust the cold air. At least you would be able to sit in front of the unit in your camper and feel warmer... These are not really "space heaters". They are small portable units to make small spaces more comfortable. We are thinking about buying one, but understand its limitations. The advantage for us is that ONE device will do 2 things, which is a space and cost saving. We have a slide on camper shell that goes on a tray top 4WD.

[@Enjoymentboy]

The math is easy. Heat pumps don't create the heat like a space heater does. They move it from one place to another. Some can move upwards of 2.5 times as much energy (in the form of heat) as they take to operate. So basically, for ever watt they consume they can move 2.5 watts of heat.

[@Hendlton]

Unless a heat pump is specifically rated for winter use, it's at most going to be good for a cool spring night. As soon as the temperature outside dips below 32 F, their efficiency plummets. I have one rated for 0 F, but it starts struggling well above that. It's still enough to heat my room, but I can tell that it couldn't handle much more. It probably doesn't help that my room isn't that well insulated either. Also yeah, a COP of 3 is pretty standard. A heat pump that draws 500W and has a COP of 3, should be putting out about 1500W of heat. It's not creating energy out of nothing, it's moving the energy from the outside air into the room.

[@DoctorKnox]

Google "are heat pumps good in cold weather". Heats pumps are MORE efficient at heating when it's cold. That's because they require cold when transferring heat. Mostpeople get this confused because they think you can't get cold from heat and heat from cold, but that's exactly what heat pumps do. This thing isn't a heat pump, there's no external condenser unit, it's doing the condensing right where it's trying to heat/cool. It's just a bad space heater and a portable A/C.

[@NoZenith]

Regarding the heatpump, older units worked good only down to about 37 degrees. Although this is a new unit, it's probably operating at the same efficiency. Point being, it's a cheap unit with horrible efficiency. Newer heat pumps can go down to 20 degrees with little efficiency loss. And if you want to get really fancy, some inverter drive units can utilize heat pump mode into sub 0 temps!

[@stephenmartin8331]

Mine keeps making a loud squeal when turned on. Sounds like a belt slipping. Haven't been able to find any information about it, or any manuals showing how to open it up to find out what is squealing. Any ideas?

[@justinsmith5533]

500 watts for ~3,000 BTU seems like a better bang for your buck instead of 1,500 watts for 5,100 BTU. But if you want heat, you're not really caring about energy consumption.

[@JeffKubel]

RTFM. Test 1: Temperature is out of range. Needs to be 41F to 122F outside with two hoses. Test 2: In range, but crippled using one hose and pulling vacuum, causing cold air to creep in. The resistance heater test wasn't pulling a vacuum so it had a clear advantage. Test 3: Yet again, out of range, but better conditions. Amazing it actually worked at all. All of the tests were designed to make this unit fail, which is disappointing... not of the product, but of the integrity of the reviewer, who I think was smart enough to know better, as he was rattling off specs through the review.

[@TheVeryGreatBear]

19:07 - With air source heat pumps this phenomenon is called COP degradation. This occurs when the temperature difference between outdoors and indoors decreases it becomes harder for the heat pump to extract heat from the outside air. To compensate for this the unit has to work harder, increasing the energy input to maintain the same heating capacity. I am not implying this particular AC/heat pump is efficient or perfect. The input power increase as the heat source temperature rises is normal for any air source heat pump.

[@davidtunstill2797]

Look at the way your central air system works pulls air Though the return in the house blowes air out the supply in the house. Cycles the same air. So what your doing venting both ways is pulling in cold air blowing out your warm air.

[@crabnuggets2059]

Heat pumps suck below 32F. That is why they supplement with electric heat stripps.

[@unusualfabrication9937]

I am taking a thermodynamics class right now and I am tempted to run the numbers...

[@chrisjc2k]

Please do :)

[@KA9DSL]

I use a my $95 5000 BTU A/C with a AC inverter drawing only 500 watts in my Van running on 3 100@ lithium batteries. Runs all night! AC sits in passenger window fine. A lot cheaper way to go. Can't deal with hoses. A very simple install.

[@RGree-co9dy]

Mine worked fine for about 2 months and now it will not charge from a/c. They have a grate warranty on paper but so far in use it dose not work well.

[@jamesstephenson8789]

How is a heater suppose to work if you have two hoses outside and one pulls in air as you say that defeats the purpose of heating

[@davidbayliss3789]

I think it pulls in air through one hose; sucks the heat out of it and concentrates it to exchange with the air flow going through it in your room, and spits out that now-cooler outside air through the other outside hose. The cold outside air doesn't get into the room (principally). With so many hoses it does get a bit confusing. :) The theory is good - but this particular unit is hyped-up a bit from the looks of it and isn't the most efficient type and isn't rated for the outside temperature tested. I'd love to have a 500W similarly dimensioned device with those hose attachments that was rated for those temperatures and that could run continuously, and was good for A/C up to at least 104. I'm not sure they're available anywhere. :( My interest in this was piqued by those additional hose attachments ... for a moment I was fooled into thinking this might be a contender. :)

[@davidbayliss3789]

nb: for more extreme temperatures and such small amounts of power as 500W, I suppose seeing uninsulated hoses are a red flag lol. With large deltas between temperatures, then all that surface area presented by long hoses sitting between the big temperature difference is going to introduce some considerable efficiency loss. Those hoses effectively become something of a heat exchanger. You can buy similar hoses but with insulated cladding that will surely make some significant positive difference to the efficiency under those circumstances.

[@danielh6059]

Heat pumps don't create any heat. They move heat found in the environment, thermal energy already there. They expend energy moving the heat. I am curious as to the volume of the room and insulation rating. That would be useful information

[@johnbobbert6024]

I mean, do you think you’re better off going with some type of propane? Heater for the cabin or do you think I should go with something like this?

[@Doobihowser]

Heat pumps are very efficient. That's why heat pump dryers plug into 120 volts.

[@mylt1z28]

It's only rated down to 41*, that's why it didn't work when the temp was 20*. Your heat pump in your garage heats at that 20* because it also has a heating element in it which the wave 2 doesn't have. This is more a fair weather heat/ac device. Think, you want to just warm up or cool down a room that may have bad airflow from your normal HVAC system or just to warm up or cool down a tent. It's not an end all be all device even though they sort of claim it is.

[@bsdavidson0360]

I think you're confused with the hose use.

[@NoahEisenhauer]

Congratulations on your cybertruck purchase!

[@jtaylor228]

Duh ! IT'S A HEAT PUMP. The instructions say not use the exterior heat exchanger air inlet if below 40 deg F. Efficiency drops to the point it is nearly non-functional. Just use interior air to supply the heat exchanger and only connect the exhaust hose outside. Just have to address the negative air pressure with some other conditioned air source. Then it will work fine (within its design limitations).......

[@masterdirk101]

Loved the skepticism, actually felt like the most well thought out deduction I've heard tyler say in a long time of watching. The beauty of heatpumps is they aren't creating the heat, they are just moving it. This results in something like 300% efficiency in regards to heat produced. Which funny enough matches that 1/3rd the power comment. The problem is the colder it is, the harder it is to find heat, this is what causes most heat pumps to take efficiency nose dives in sub freezing temps. This is why most will have a resistive strip heater as a backup, this is usually where the expensive part comes, but now some of the more efficient heatpumps can get usable heat out of -11F temps.

[@DoctorKnox]

A heat pump requires heat and cold transfer in two different locations (usually inside and outside of the house) you can't have it in the same room, even if you vent it off. Heat pumps are MORE efficient in cold weather because of the necessary heat transfer. Standard heating units and A/C are less efficient in cold weather, not heat pumps, yes they are very similar, but not the same. If it were a real heat pump, it should have done very well in that weather. The issue is, it's not a heat pump, it's a space heater, and a space heater can only procude 3.413 BTUs per watt.

[@masterdirk101]

@@DoctorKnox they factually don’t perform better when it’s cold. Lower the temp harder it is to get heat, harder the system needs to work to get less return. Results in more defrosts and more backup heat. The baby portable unit is a heat pump.

[@RVingTheCountry]

Inky testing the heater? Cmon man. Haha it’s a portable a/c. Now I gotta go to another vid.

[@patriciajones9711]

Thanks for the video.

[@andrewcastiglia9548]

Heat pumps are limited by the pumped fluids' ability to evaporate/condense. If the ambient air is below the evaporation temperature of the fluid then the heat cycle will be unable to operate and you will just be pumping liquid at low pressures which is bad for a compressor pump. I bet the reason that the power level goes up is because as the evaporator warms up above the vaporization point of the fluid it quickly turns to gas increasing the pressure which in turn increases the pumping resistance that the unit sees.

[@typicalpctech6674]

You described clearly what the hoses did before testing!!! Then you forgot what you said! lol Sorry man, but if you can't laugh with me/us, I'm sorry! So, you explained that the 2 hoses on the back are the heat pump function... And you explained in a tent, the front should be vented outside!!! Good Job, now you are now realizing your error I think in the video, but you still have outside air being sucked in instead of the room air! Both hoses for heat are designed to be in the room, the front hose should be outside! :\ I'm pretty sure, I've never messed with one of these, but they are supposed to be super efficient! I definitely could see how it could be misleading or confusing!

[@garrettsmith7359]

Not defending the product but you don't need ventilation to the outside for an electric space heater. I believe using the heating option without ventilation to the outside would work way better. With a.c. you need the ventilation to transfer the heat out of the house.

[@TylerTubetoo]

learn how heat pumps work

[@twitchymcnutz1095]

There wasn't a big difference in the heating there. You went from 54 up to 65 for an 11 degree change. Then with the space heater you went from 59 up to 72 which was only a 13 degree change. I know if you only look at the max temp number it seems like a big difference but you were really only testing how much change they could make in a 1 hour period and that was actually fairly close. If you wanted to look at max numbers then let them each run for several hours to see just how hot they can make the room.

[@Ghost29303]

I was so much in a hurry to rush to the store and spend $1200 for a portable AC/Heater . LOL

[@AquaTech225]

Should have waited until a major holiday though. Could have bought the unit and battery together for 700 something 999 after tax. But for a factory refurbished on eBay. With a warranty either a year or two. Can’t remember. Factory refurbished. It ships in the factory new box all the factory components and hoses ect. And be in the condition of basically new. That’s how I bought mine. Not a scratch or ding anywhere on it. All the pieces and parts and adapters look brand new also. Battery looks brand new. A from day one worked like it was brand new. Tax a shipped to me was $999.00 for the AC and battery combo.

[@c117ls7]

Heat pumps start losing efficiency at 35 degrees. Exponentially under that. Your heat pump in your garage should have resistive heating elements as well. Its probably using 1 or all of them to supplement during cold weather outside

[@Compman007]

I think it is more intended for environments that dont get below like 50, thats not a comfortable temperature to sleep at for some people so they would appreciate being able to get like 72 out of 50 degree ambient, Its not really intended for environments like ours that actually get cold
