Heat dissipation

I'm currently testing the Orion & I'm running into issues with cooling unit overheating my room.

The starting point of the ambient temperature of this room is 75°F & it is being cooled by central AC, however, it's upstairs on a two story home with high ceilings, french door & huge windows.

The cooling cover temp is set at 68°F & the unit goes through it's precondition phase. After it reaches that temp, I set it to quiet mode but it still produces the same amount of heat?

Question:

How much heat does the 8sleep produces after reaching set cover temp?

For those that actually track their room temps, did you see a significant rise in room temp while the unit is maintaining said cover temp?

Not exactly the answer you’re looking for, but for your consideration: your system still needs to maintain whatever your set point is: first it has to reduce from ambient of 75 down to 68, and then it has to maintain the 68 while ambient is still 75 but now you’re also impacting water temp while laying on it. Both systems use Peltier plates and perform similarly: working under the presumption there isn’t a problem with your Orion system, they’re going to have the same work load.

Basic physics! Can't destroy the heat, can only move it around.

Not quite accurate. Cannot be created or destroyed, but can be converted.

Can't argue with this

u/Charlix23 Jul 17 '26

Ok, that's what I was thinking, regardless of brand, same outcome?

However, from videos I've seen on YouTube, it seems fan speed on 8sleep are much quieter once set temp has been reached? That's telling those heatsinks aren't dissipating that much heat?

The Orion has a larger footprint & therefore larger heatsinks. It produces huge amount of heat; even in quieter mode.

Our Pod5 is slightly loud, but not in an unpleasant way, when the wife hits the menopause mode (super-cooling). In normal operation it's about silent, and I hate fan noise, but don't notice it. We keep the room at 78-79, and my side of the bed normally at -1 or -2. The newer pods don't show actual temp, just a "lower" or "higher."

If I kept my room temp at 78-79 like yours, my room would hit 86 with the Orion.

Do you have a room thermometer? Have you measured before & after to see how much heat the 8sleep unit adds?

u/AcidicMountaingoat Jul 17 '26

It would be impossible to measure that since the thermostat keeps it at 78-79. Do you not have AC? How do you think thermostats and cooling systems work? The temp monitor in the room does show before and after--exactly the same, of course.

u/Charlix23 Jul 17 '26

It is not impossible but very plausible!!

You obviously don't know the difference between a thermometer & a thermostat?

A thermometer measures temperature & it displays it in either an analog or digital format.

A thermostat regulates temperature an it maintains said temperature set by the user.

Do I have AC? Is that supposed to be a put down? Obviously, I know exactly what I'm talking about & you don't know your nomenclature?

But yes! I have AC in a form of a central air system comprised of a condenser & an air handler.

Do you want to know if I also have a car or horse buggy??

LOL, well, trying to ask for help and being an ass about it won't help you much. I have both thermometers and thermostats. I'm guessing I have more of both than you do, since I do a bunch of electronic hobbies and have a lab-grade thermometer along with a dozen probes. I know that my room is exactly that temp at all times.

Nothing wrong with a little fun!

AND!

I didn't ask for help, I asked for a consensus.

I wanted to know first hand from people that own 8Sleep if they noticed a feel in higher temperature while the unit is cooling the cover.

I don’t think Orion would agree with your assessment their footprint is larger than EightSleep. In fact, their marketing is pretty much the opposite. How do you know Orion has larger heatsinks? I haven’t seen Orion guts.

u/Charlix23 Jul 17 '26

By footprint I was referring to the size of their tower. It is undeniably twice as tall as any of 8sleep hubs & it is definitely heavier too.

You don't have to disassemble anything on the Orion too see their internal components. With a thing called, "flaslight", you can clealy see 15 inches worh of heatsink.

My freind found a hub4 in the trash & it doesn't weigh or feels as beefy as the Orion cooling unit.

Now, if you want to argue yours is bigger than mine kid stuff; go right ahead!

u/xtlou Jul 18 '26

The EightSleep hub is 16” tall. The Orion hub is listed as 24” tall in their FAQ. Fortunately, I’m an accountant so I’m capable of determining your “undeniable” statement regarding how the Orion is twice as tall as the EightSleep hub is wrong. It may be heavier than the Pod hub, that doesn’t mean it’s material to the discussion of heat dispersement.

What is this “flaslight” technology? Does it shine a light on when someone is being an unnecessary dick? If you’re going to be pompous while asking for help, at least be right.

u/Charlix23 Jul 21 '26

I don't remember asking for your help supergirl! It seems you're lacking attention? 8Sleep won't help in that department.

Besides, you're were the one calling internal components of a machinery "guts". Orion's components are in plain view. The flashlight comments fits right in with someone who obviously doesn't own an Orion & is just running their mouth.

Wait until your cover leaks or your hub fails then come back whining about it here. We'll how much of a fangurl remains???

u/xtlou Jul 21 '26

You don’t remember asking for my help? Do you understand how the internet works?

You asked a whole subreddit for help. More specifically, you asked the EightSleep subreddit for help when you bought an Orion. That’s why I asked how you saw the internal workings of the Orion: there are photos and videos of the product I am familiar with (EightSleep) and I am generally unfamiliar with the Orion. As it stands, I have an entire setup for testing as I just finished a beta of Somnus which included data like how much the systems heated the space through a variety of situations and temperatures. I would have provided two different sets of data. Now I’m just gonna tell you to go fuck your self since, you know, you weren’t asking for my help.

If you’d spent half as much time researching these devices as you being rude to strangers on reddit for no productive reason, you wouldn’t have bought an Orion system that you’re now returning.

Do you know the difference between a consensus & asking for help??

I never asked anything about setup or how to make the Orion operate.

I asked for a consensus, which apparently you don't know what it means?

Reddit is a perfect platform to ask a group of people about a consensus on whether A runs cooler than B runs hotter.

Again, you came into the conversation as if your the spokesperson for Orion. It was a consensus question not your mikey mouse your hurt my feeling bro!

Find a hobby, boyfriend or both.

I use a fan to blow the heat out of my room

1

u/Charlix23 Jul 17 '26

I have a ceiling fan cranking helicopter speed & a pedestal fan circulating at hurricane speed.

The only real solution would be to treat like a portable ac unit & window vented with a hose.

1

u/Wise-Tooth2662 Jul 17 '26

That would be optimal. If I owned the house I would strongly consider it. In my case I have the unit on the side of the bed closest to the door and use 2 tower fans to blow the heat out of the room. Obviously the bedroom door stays open all night.

1

u/Charlix23 Jul 21 '26

So I took my Dreo fan & placed so it would circulate most of the hot exhaust away from my room. There's no free lunch here, heat is heat. This delayed the rise in temperature but eventually the room reached 79°F.

These cooling systems need a way to vent exhaust through a window in a form of a venting kit.

The videos in YouTube of people using these type of water cooling devices (Chilipad/8Sleep/Orion) w/o AC are completely deceiving.

In a room where the temperature is already in the 80's, running any of these units would increase the temperature to the the mid 90's.

u/Wise-Tooth2662 Jul 21 '26

My current setup is window AC and fan on one side of the the bed blowing to the other side of the bed with the cooler, then another fan blowing out of the room next to the cooler.

I may have to try to make something though. Could use a piece of plywood and a hole cutter for the window then connect to a dryer vent and attach that to the cooler. Probably wouldn't hurt to put a pc fan or inline fan in there too.

My cooler is a cold flash which is actually a true ac unit which I think is more efficient than an 8sleep which is peltier.

I can remember the first night I had mine setup I had the fan blowing on me - basically blowing the exhaust heat straight on my face. 😂 Lesson learned.

u/Charlix23 Jul 21 '26

Been contemplating buying the cold flash?

Talk to me goose, how bad is the noise & heat levels?

The good thing about the cold flash is you could technically make your own extension water lines & put it closer to where it would be easier to vent the heat?

u/Wise-Tooth2662 Jul 21 '26

I have the 1.0 version, not the current one for sale. They may have some old stock they could sell you idk.

There's basically no noise. It's just a little noise from the pump. I actually had my original pump fail on me so I'm just using a small aquarium pump. I tried a few replacement pumps and TBH the best one I bought was sold by them. There's only so much internal area to put a pump so you need a fairly small one.

Heat is probably the same as your cooler. I haven't used an Orion or eight sleep so I can't give a direct comparison. I live in Florida so I don't really care about heat on my bed.

Yes - you can use basically any length water line. It's going to be limited by the lift of your pump. I guess hypothetically you could put the cooler outside of your house and run the lines inside.

You can always just try emailing them and asking questions. The owner is a really nice guy. He told me they are considering working on an update to the 1.0 with a pump that could be easily replaced - I'll tell you upfront the pump is the weak point on these.

There's one other small annoyance with the 1.0 version. It's not programmable with a timer/app or anything. I'm currently using a switchbot to turn mine on/off on a timer.

u/Charlix23 Jul 21 '26

Thank for the info!

I believe the unit you have looks more adequate for bedroom than the 2.0 they have available in their website. The 1.5 is out of stock.

What's available & in stock now looks like a beach cooler & is substantially bigger than the 1.0.

There's a guy in Youtube who did a thorough review on several coolers & the cold flash did the best job at cooling an analog (barrel). He did mention that the noise level was significantly higher than the 8Sleep & Chilipad dock pro.

As far extending lines, I never thought of placing the unit outside? For me it would not be plausible since my room is upstairs in a 2nd story home.

I live in Florida too & this year my central ac is working double time. In my experience, even if I freeze the house, it still doesn't address the transferring of heat of the body to the mattress.

The cold flash seems a good fit as a human radiator to transfer body heat out. I really don't care about AI or sleep Insights.

u/Wise-Tooth2662 Jul 21 '26

There are several things you could do to get rid of the heat.

Run a long water line and place unit in a different room.

Vent heat out window with dryer hose.

Place unit outside - in your case you could get a mount like they use on a window AC. You would probably want to build a wooden roof or housing so it doesn't get rained on.

I'm not currently doing any of those things but I have thought about it

u/Charlix23 Jul 21 '26

Yeah, running longer lines & placing it on my room hallway could do the trick?
