    A distributed cloud firm is working on Ryzen chips that could warm your shower: France’s Qarnot has won a contract to provide heat for 1,500 social houses in Bordeaux using AMD processors. The company makes a device called the “Q.rad” that utilizes three CPUs to provide heat and serve as a node in a distributed cloud dedicated to jobs like rendering VFX or financial risk analysis. Thanks cageymaru.

    Qarnot's tests also showed “a performance gain of 30 to 45 per cent compared to the Intel i7 we were previously using.” In, therefore, comes the Ryzen and out goes the i7. Qarnot is now thinking about what else it could with AMD kit, and has “a boiler for domestic hot water and swimming pool heating solutions” on the drawing board. Qarnot's not alone in using distributed servers as heaters: Dutch companies Nerdalize and Eneco adopted the idea in 2015.

    Why didn't anyone think of this before? Time to crank The voltage!

    But a hot water boiler heats water to around 120F.

    Hmm... I guess that works.

    A boiler usually heats water to 140° at least. A domestic hot water heater needs to be at 120° minimum to prevent legionaries disease.

    Depending how many cpus are connected in the loop, that's 60c. They can always have an electric backup to maintain that temp should the cpus not provide enough heat.

    "After Legionella grows and multiplies in a building water system, that contaminated water then has to spread in droplets small enough for people to breathe in. People can get Legionnaires’ disease when they breathe in small droplets of water in the air that contain the bacteria."


    Well that sounds terrifying.

    For those worried about insufficient heating for water purposes you are correct. The original article was badly worded--the device is a space heater not a water heater. Just looking at Home Depot a typical water heater looks to be 4000-5000 W. I would be a little worried if 3 CPUs were consuming that much power. The actual device is a 500W space heater that automatically reimburses the host for the consumed electricity.

    Edit: I noticed that the original article is by a British publication. Maybe "heat your shower" would be understood as "heat your bathroom" by a British audience--or it could just be badly worded.

    They're using the wrong CPU's for the task. They should be using Intel Prescott CPU's. Those things were made from Hell fire Silicone. Although they may turn the rooms they're in into Sauna's if you pair 3 :happy::happy:

    In the op, the quote says hot water and heat your swimming pool. They're talking about water as well.

    I've heated my swimming pool with my rigs. :D The only problem is you have to make sure you don't get condensation....

    It worked well. It was like 10C higher than my neighbor's...

    Next they'll use a Vega64 GPU to boil water for tea.

    Looks like I completely overlooked that. I guess if you use 30 cpus you would have enough wattage. I guess you could use the cpus to heat the water to a moderately warm temp such as 60c or so then use a regular electric coil to bring it up to whatever temp desired.

    Coincidentally; last winter I used my PS4 as a foot warmer. I would play while keeping the heat low, but my feet would get cold, so I would drape a blanket around the furthest back portion of the PS4 and let the vented hot air heat my feet. Good times for my feet.

    Lol they should try it with the 7900x and the rest. Those fuckers are even less efficient than Zen.
    Guess it would also cost them 3x as much.

    'ducks before juantai and co comes along'


    On a more serious note, this isn't really a new concept, it's done in some agricultural lighting systems, to pre-heat feed water in cold climates and cool LEDs at the same time. It's not much different to a solar water heater either in this capacity.

    Novel way to make use of waste heat I guess.

    Maybe I'll install a paddle wheel generator in my toilet so when I drink lots of beer
    I can piss-power the beer fridge.
