@ 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

[@RonM.]

I kinda agree with you, but I feel like for the price he paid for it himself without it being sent to him/with a sponsor, he probably read the instructions. Nobody would actually do that and play dumb when they're playing with $2000 basically. But then again we're talking about Tyler here...

[@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.

[@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.

[@DrBerkantAtay]

For heating purpose and the unit is inside, it is recommended to use only the exhaust pipe going outside.

[@kritsadventures]

Better to pull a vacuum when it's that cold because it can keep reheating the already warmer air until it gets very hot

[@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...

[@thepatternforms859]

Sorry but what?

[@domin727]

@@thepatternforms859 How heatpumps work. Do you need it with pictures?

[@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🤔

[@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.

[@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.

[@dougwashburn8014]

@@nevernever2002 Sure you could flip a window unit around if you want all the humidity from outside to be dripped all over your floor. AC units not only remove heat but they remove water from the air.

Straight from the first page of the manual: Ambient Temperature for Operation: 41F - 122F... Tell me you didn't read the manual without telling me you didn't read the manual

[@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.

[@robertcase2252]

[@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.

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).......

[@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.

[@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.

[@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.

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!

[@KA9DSL]

[@kyleking9081]

[@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

[@matty85992]

I would try running it on ac mode with the pipes running from the front out the window because the heat that comes of the back gets toasty give it a shot we use our portable air conditioning units to help heat our kitchen in the winter

[@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.

[@vapoe]

It’s a heat pump. They’re all basically useless at heating when the outside air goes below freezing. The fact that it’s even putting out 60° air without an auxiliary coil (which is what your home unit you referenced is doing) is pretty remarkable.

[@NoZenith]

[@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.

[@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.

[@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.

Heat pumps are incredibly efficient. I have a hybrid 22 seer mini split rated for 12,000 btu. BTU / SEER = wattage. In this case, 545 watts. This is measured with an integrated app, a "kill-a-watt" meter, and a kasa smart app. I can change a room's temperature in a few minutes. 6,000 btu from 500 watts is actually pretty bad, I have a 5,000 BTU window a/c that cost $99 and uses around $450. Their device is around 10 seer efficiency and is kinda garbage. As an actual benefit, heat pumps usually can run at their peak wattage continuously. Whereas a 1500w space heater usually is not meant to run at 1500 watts continuous. That said, it's garbage and overpriced.

The video and some of the comments are.. interesting (aka super wrong / naïve). The unit is an heatpump that works at an (in ideal situations) at an 3.1x efficacy; hence the 500w -> 1500w heat. It HAS TO use TWO of the pipes (on the backside) in order to properly function; One pipe pulls in fresh air from the outside, extracts some heat from that and exhausts the now colder air via the other tube (if this is not done it will not do any work!). The same happens on the front of the unit; It pulls in fresh roomtemp air from the front, runs that though the radiator that now has the added heat that was just taken from the outside and exhausts that via the top back into the room. The reverse is true when using the unit to cool; hence you always need TWO pipes on the back (when using the unit indoor). Also the unit can only work up till 5 degrees Celsius, after that it will peddle (defrost) A LOT and it just won't be worth it to run at that moment. I use it to heat (and cool) my 10m2 office and on eco mode it only uses 287w and even less for cooling. The stated numbers (aka the 500w) is only what the unit is able to do at a maximum, it will use less if it is properly used.

[@DoctorKnox]

Too bad real heat pumps don't actually pull air from anywhere. Where's the air ports on your fridge or freezer? (Hint, there aren't any) They are heat pumps too.

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.

[@Slimjim-gt1zv]

Heat pumps will really only run and “work “ down to about 36 outside and this is on full size residential high efficient systems. So 20 out side is way to cold

[@markbenoit8358]

You didnt try to run it without the tubes. Only thing you missed. I bet it works better. Do a video no.2

[@NoZenith]

That's not how this works

[@thepatternforms859]

@@NoZenithwell if the tube is pulling in air colder than 40F from outside then the heater won’t work. So he needs to only use one tube (exhaust) and allow the machine to use the 50F degree air already in the room then it would heat the room up

[@NoZenith]

@thepatternforms859 I don't know if that's got what this guy was talking about or not. But running it with no tubes would be doing almost nothing because it would be dumping All the cold air right back in the room too. I've seen people misunderstanding the unit because the advertising isn't all that clear and they don't have the mindset to understand this isn't a resistive space heater.

[@Matt23488]

I think when the air is too cold, it can't use very much energy because it's not able to extract very much energy from the cold air. So it's just a product of physics since the amount of energy the unit consumes is proportionally related to the amount of energy it can extract from the intake.

[@wurthmannd024]

All heatpumps are almost useless under 30°. That's why they have backup heat strips

[@crabnuggets2059]

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

[@drlau9]

Thanks for the great video! I think from your video, it'll struggle to heat a room, however if you attach the exhaust tube inside your sleeping bag or duvet it's going to be rather warm? So really this is a personal heater / cooler?

[@Kodiak5250]

Also heat pumps start losing all their efficiency at 20° most heat pumps use a back up heat strip at that temp

[@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.

[@AquaTech225]

It don’t get cold here. But it works fine in the 30’s here

[@lukeabs9333]

you should do another survival challenge video, super cool stuff! keep it up man!

[@BerserkingKantus]

Heat pumps pull heat out of the air and pump it where you want it, space heaters heat up coils with electricity to generate heat. A heat pump is not made to generate heat.

[@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

[@jayblescashews]

Appreciate the honesty but i think its designed for small rooms and vans

[@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.

[@Tylersimmons1995]

I appreciate it but it would have been so funny to compete the heater vs fire.

[@hobbyguy4640]

Shout out to Tyler for buying so he can give an honest review of an expensive product.

[@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

[@lanceboudreau3630]

Bro you do understand that it's basically an air conditioner that works in Reverse right the only way for it to properly work it's for you to keep the inside air and keep recirculating that and as far as bringing it up to 70° or 68° at 500 w that's one third of what a space heater would use which is excellent not to mention you were trying to eat a room bigger than it was capable of and it still did it

[@Bound4Earth]

Did you not test the AC part?

[@tacticaltony49]

Heat pumps are more than 100% efficient because they’re not adding heat using electricity they’re moving it around kind of and modern heat pumps can get 300% efficient compared to a space heater with a theoretical max of 100%

[@normalrickandmortyfanscong4813]

Your reviews are always the most honest lol

[@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.
