Founder Explores Liquid Cooling To Heat Hot Tub With AI Model Waste Heat

@theysayheygreg @DanielleFong a lot of houses have heat exchangers that take shower drain water and loop it around a pipe to warm incoming water heater water. so thats another option https://www.amazon.com/efficiency-ThermoDrain-TDH3620B-DR-PEX-performance-recovery/dp/B0CRFSCWBZ/

@ZyMazza you need 2-3 kW

we have a crazy idea / plan and would love your help

@DanielleFong check out plate coolers for marine applications or even home beer brewing! a wort chiller setup might come as a kit for basically what you want

@DanielleFong dual loop with a heat exchanger setup i’d guess? you probably don’t want the pool water in the actual hardware cooling loop

@DanielleFong youre gonna need a lot of 3090s to heat a whole hot tub

@DanielleFong i havent done the math but im skeptical. A hot tub has a lot of water and needs to be very hot to be comfortable!

@ZyMazza you need 4-8 or so

@theysayheygreg dual loop for sure

@DanielleFong a copper plate exchanger will get you better transfer rates than coil immersion https://www.homedepot.com/p/VEVOR-Heat-Exchange-5-in-x-12-in-30-Plates-Brazed-Plate-Heat-ExchangerCopper-316L-Stainless-Steel-Water-Heat-Exchanger-QHBSHRQ51230HDK92V0/331565369?source=shoppingads&locale=en-US&fp=ggl

@ZyMazza @DanielleFong ya but you can buy inflatable ones at walmart that plug into 120V with an extension cord, if you think about it

and it can heat up slow, then you only need to replace losses

@DanielleFong @ZyMazza Of direct heating, that's not what you'll get from residual heat from the cards even in a closed loop system. It'll take you a week to get it up to temp.

@MilitantAI @ZyMazza residual heat? you need multiple cards

@DanielleFong yessss, the hot spring comes to life

@DanielleFong Heres a good writeup by someone who heated their garage using a BTC mining rig. Essentially the same idea

@DanielleFong I’d assume lots of pumps - or maybe just large pumps, dual loop obvs so you keep loop coolant and hot tub water separate

LTT has a variety of videos on using Linus’ rackmounted gaming pcs to heat an in ground pool. Though not circulating pool water directly.

@DanielleFong this oughta do it!! 😂

in all seriousness good luck with the project this is cool :)

@DanielleFong Two track heat exchanger plate (or art/sculpture if you’re daring). Could immerse, but maybe easier external nearby.

Circuit for the side going into tub should be halogen resistant material.

Pre heat the tub water if possible, maintain easier than cold start

@theysayheygreg 100%
