So much for PoS from PoW for ETH

60 degrees?, do you use that hot water alone or mix it with cold? 50 degrees is already hot, for me around 40 degrees is ideal, around body temp.

Anyway, a typical shower heater is around 6000w, maybe miners that pulls at least double like12000w can deliver that heat, it is not efficient(heating-wise) but heat is just a by product, a farm with at least 70-100 cards might do it. Remember the solar solution are just tubes, and it can get as hot as a roof top in a mining room, sometimes it is even hotter than roof tops, also mining rooms deliver near constant heat unlike roof tops.

Size do matter as a storage, that's what water boiler tanks used to do, store hot water before the electric shower heater became the new standard.

Yes, 60 degrees in the tank or at the water heater outlet. Because then the water will run through some more tubes that will cool the water. When you get to the shower, the water should be around 40 degrees.

I am not questioning the power of the miners, capable of heating water, what I am saying is that in order to heat the water effectively, the water had to pass very close to the chips. That's where the heat is. If they pass 20 or 30 centimeters away, they will only catch the air emitted by the miner, who will walk at around 40 degrees. Which will be insufficient to heat water effectively.

Bigger tubes then let the water rotate through the piping that would reduce the temp(60-40), then those pipes will eventually heat up and then they won't absorb much of the heat before bathing, those pipes should be plastic(not a very good conductor of heat) but still the pipes beside the miners are metal.

Worst case scenario if the water is warm just 30 degrees max performance, your electric heater will not use 3000w of heating power, just 1000w because at low settings the water is already 40 degrees. That's 2000w savings.

It really can make it easier to reduce water heater consumption. But even so, water will hardly come out of close to the miners at 40 degrees, unless the tubes pass really close to the chips.


Following our conversation about plants, I found this news very interesting. Where in the Netherlands a tulip producer in partnership with a bitcoin miner, the greenhouses are heated:

Wow and the news is just December 12, very fresh.

I guess my water heater theories will remain theories without application/experimentation and computation. Letting it pass directly at chips is so much trouble, cost, and hassle, it was never an option.

At best, savings for bath heater, you still want to install electric heater either way because if you temporarily lost internet then you freeze in the shower LOL, things happen.

In fact, there are already a lot of these solutions and I saw the first working projects more than 5 years ago. I think it's easy to find on the internet. The amount of heat generated depends on the amount of mining equipment, but this project requires additional costs, which is not always beneficial.

That's right, I think the cost of installing this type of solution is too expensive for the benefit. If it is to heat the water in a swimming pool, it can be used, but I think it would be too expensive for the efficiency generated. I find it more efficient to use this heat to heat the environment/house than to heat water.

You need to calculate how much money you pay for heating the water in the pool, and how many miners you need to get the same result. If you have video cards, then water cooling for each will be expensive, it is cheaper to immerse video cards in a special liquid that will transfer heat to water through a radiator. But I think that 99% of miners will not do this.
