Being an HVAC engineer expert and run my own business offering design services, this thread was fun and hilarious to read.

Guys, heatpumps take heat from outside to inside, or from inside to outside. They MOVE heat, aka they pump the heat. Hence Heatpump.

Nextt, Fog would not prevent this from working. Would probably transfer heat better due to higher humidity, but ultimately might decay the coil if a coastal region.

These units are fine, and I recently got one for my buddy to install for himself. However, eventually these linesets, not being brazed in will leak. Probably a few years down the road if done right, but they leak very slowly. A brazed connection is essentially metal melting the connection point closed off so no leaks if done right.

Next, if you oversize these, they wont dehumidify because when they slo down their capacity, the coil gets less cold. it takes a cold coil to dehumidify inside, so right sizing is important.

These are not meant to be data room units, and if its used in some mining operation, there should have been calculations to say that there is X amount of heat dissipation in watts from these GPus, and figure up what that load looks like and size accordingly. Of course with none of that running and 18K in a 10x12 room is WAY too big.

I actually wanna add one to my own garage but getting a power circuit run is gonna be a pain as my panel is full up, and my basement subpanel is almost full as well.

I have this, works well in my garage. I paid $1100 in May 2019. Yikes at current pricing.

I installed the 24k unit last time this went on sale. The whole unit was very well put together, with clear and concise directions. Because I ran it from inside a room, through a garage, and to the outside I had to buy some small things like another wall sleeve, straps to hold the lines, a finishing gutter cover and a wall mount for outside.

I think my install was quite a bit more involved than a lot of installs would normally be since I had to core through brick and run new conduit from my panel. For the most part the kit will have most, if not all of what you need. Check both boxes you get for damages, I got a unit from HD first that was half crushed, the unit I got from Costco had the fan cover bashed in a bit but I hammered it back out with a mallet and block. Too much trouble to return and wait for another unit to ship, and I can't see the damage now. Don't get halfway through your install and open the next box and see an issue!

Performance is great, it's very quiet and heats and cools AWESOME. I quickly got the house down to 65 degrees during the heat wave, and now use it nightly to keep the house comfortable. The air it puts out feels nice, I'm not sure how to describe it but it's different than air out of my vents from the furnace.

I'd definitely recommend these units though, definitely my favorite upgrade to my house.

Wondering this too -- is this actually a sale or just regular price?

It somewhat depends on the outside air temp / environment, ceiling height, insulation… that said, I use one of these to cool a 2BR minimally insulated ranch in northern PA with no problem, and I also use it for supplemental heat in the winter.

i have this exact 18k BTU unit cooling a 12x10 room (120 sq feet)

it does shit job in cooling the room lower than 95 degree unless i have lot of fans pulling outside air in

i might need a 30k+ unit for this



PS: i have 100 GPU crypto mining so it generate heat, the unit itself is way too cold when all the rigs are off
also FYI, the unit itself require a 20amp 240v dedicated breaker, electrician test it pull 9amp max when running full power
Is the room insulated? Seems crazy this thing couldn't cool 120 square ft

Crypto mining room! I added the 18k to cool my basement with 57 mining 3060ti and it did just fine. But 100 GPU is probably to much for an 18k.

I hope you aren't blaming the unit for not keeping the room cool while you're running what is essentially a big heater (100 GPUs?) in it non-stop. This should handle 120 sq ft like nothing, but that's a serious rig working against it. What are you still mining on GPUs?

Can confirm been $1300 since last December. No idea how this is a deal other than being a decent Costco price.
