Recycle uses of the heat from mining equipment.

[Queentoshi]

Recognizing that the heat generated from mining equipment can become a intolerable, a discouragement and a challenge, it is in every miners benefit to find more beneficial uses for the heat energy from their equipment, rather than considering them totally as a waste. A forum member already has stated one use of the heat which can be recycled to heating homes, which can be beneficial for people in very cold places like Canada where their home require heating to also cut cost, some other applications where the harnessed heat from mining machine can be used are;
(a)For heating water and food possibly.
(b)for drying laundry and food that needs drying.
Which other possible domestic use can you think of?

I think if you have a garden and you love plants and lovers then you can also use the heat from ASIC miner to heat the room to keep the room of your garden warmer. we know cold places like Canada the plants can not survive in cold places so having an ASIC miner can help heat the garden and it can also cut your Electricity than having a normal heater which consumed the same as a miner.

And I saw more from this link below that you can recycle the heat and use it for other things like wood drying and also for water heating.

We were going to use S19's to heat our greenhouses as we have super cheap power. But when we go to it the price of ASIC's tripled and not longer worked for us.

I'm excited about the new water cooled rigs, that can really make the heat energy useful.

Floor / baseboard heating, water heater, pool heater ground heating in greenhouses

The issue with greenhouses is they tend to be humid, which is not good for miners. And during the hot summer months you need to get more heat and humidity out of the space.
Over the years there have been a lot of people with a lot of plans to do something with the waste heat.

Using liquid cooling is fine, but do you want to have heated flooring during the summer? If not you have to have a 2nd water path to move the heat someplace else.

Also, it adds complication. I have an air cooled miner I can put it anyplace where I can move enough air to keep it cool no though given to plumbing....

This is the main problem with the heat, you need to get it out of the miner but at the same time you must be careful what air you get in also, so you will definitely need two circuits here, and then you have the distance if your greenhouse is like 50 meters from the room where you have the miners you need a lot of fans to push it, maybe dig a trench for the tubes so you don't lose that much heat but at the same time, you have to watch out if air goes above 30C not to ruin your plants, so another exhaust.

A lot of pain in the ass if you're working on small-scale stuff, might be really enjoyable as a hobby if you like this stuff but probably at one point you will get bored playing around all day with settings and temps and fan speeds depending on how sunny is outside.

Our green houses are fully automated. Exhaust fans, intake fans, heat, humidity, CO2 generators, lights, water and nutrition. I was going to use the output of the dehumidifiers to drive the ASICs as it's filtered as well.

Yes, definitely take care that in the summer to dispose of heat, for example, having a small cooling tower or using such or such a fan heater installed outside the room to cool the immersion fluid, I think all this can be implemented.

Alongside heating, I’ve been testing a prototype that uses ASIC waste heat for water desalination. With coolant at ~50–60 °C, a membrane distillation module was able to produce clean water in lab and field runs.

Has anyone else here tried routing miner heat into water systems?

[NotFuzzyWarm]

Membrane desalination has nothing to do with temperature of the water so makes no use of waste heat....
All a miner cares about is incoming fluid temp and the flow rate. They have a fairly low max pressure of maybe 100 psi so that may not be enough to push the required flow through the filter. The fluid itself must be non-corrosive (no salt water) and clean. Can be done of course, just pay attention to those points

[SuperBitMan]

Well this you have said is a very good idea and it will be more useful in cold nations because they can really use it to heat up there home. I'm very sure some miners are already making use of this heat gotten from there mining equipment, some miners may have the idea but may not know how to recycle this heat to there own benefit and I think also bring up idea on how to make it work is also very good.
I believe those who studied something related to electric will have more idea about this, for the fact this has been mentioned some people may eventually try it out, I believe watching some videos about this in YouTube will help also.

Speaking of individual use, I've seen engineers use several ASICs to heat a house. The downside of this solution is that you need to be an engineer and maintain the equipment yourself; otherwise, it's cheaper to use a heating boiler. But a heating boiler is essential as a backup, otherwise you'll get cold if the ASICs fail.

The only thing that makes sense is using miners as heat machines.

Do not use miners to heat water that you are going to drink or use them to cook food if possible, let's not forget that the heat is been dispense out of the miner and that's coming from the motherboard and power supply, they have capacitors and resistors on them, the heat can't be consumed as food you are slowly poisoning yourself.

The components in Asic miners consists of sulfuric acid and inorganic solvents, because if a wet capacitor is already available in your psu you won't know until the miner start to break down, I will stick with using miners to keep your cold home warm only, anything else might not be as healthy as we think.

Our prototype uses waste heat from Bitcoin mining to desalinate water via membrane distillation (MD), with a dual-loop setup that keeps miners cool and produces clean water:

Cooling Loop (Distilled Water):

A closed loop of distilled, non-corrosive water (or dielectric fluid) directly cools the ASIC miners.
This loop absorbs heat from the miners, reaching ~50–60 °C, and transfers it to a heat exchanger without compromising miner performance (inlet temp <40 °C, flow rate optimized).


Seawater Loop (Desalination):

Cold seawater (15–28 °C) is pumped into a separate loop, isolated from the miners to prevent corrosion.
In the heat exchanger, the hot distilled water from the cooling loop transfers heat to the seawater, driving the MD process.
The temperature difference (50–60 °C vs. 15–28 °C) creates vapor that passes through a hydrophobic membrane, producing fresh, potable water.



Bonus: The desalinated water can top up the cooling loop, reducing maintenance costs for miners. No high pressure needed (unlike RO, <50 psi), and the system integrates seamlessly with existing liquid-cooling setups.

Greenhouses get humid, bad for miners. Summer needs more heat removal. Liquid cooling adds complexity and may require separate heat paths. Air-cooled miners just need airflow, no plumbing needed.

I haven't seen mining equipment in greenhouses. If it's air-cooled, there's a noise issue. Water cooling is usually used for this purpose. But greenhouse farming seems more complicated to me than mining, because even the smallest particles can ruin the harvest.

you could run these in the greenhouse

https://www.ducting.com/product/aluminum-flex-280/?

they would not release air in the green house.

run then under the plant tables and let the air out at the end of the greenhouse.

they would be like a radiator.

Thanks for the source, but I'm not an agronomist. I need to set up two heating systems using ASICs and a backup. If the power goes out and I'm not around, the entire crop will be lost. I've seen greenhouses with heating systems where people are on duty 24/7.

The digester in AD power plants is heated to keep microbes happy for gas generation.
Often many AD plants have abundant power "pockets".
Run ASICs from otherwise wasted power -> utilise their heat for biogas production.
