Heating the house by a mining farm with full compensation of electricity costs

The article A mining farm in Norilsk earns 15 million rubles per day on bitcoins. Why was the equipment placed there? examples of huge mining farms in Russia were shown to receive bitcoin cryptocurrency.

Their main problem is heat dissipation. If there are no problems with this in winter, then in summer, overheating causes equipment shutdown. What if the heat generated from a small mining farm is used to heat your home? Moreover, preferably through water heating. It turns out that such systems have existed for a long time. Called: immersion cooling equipment.

In most cases, it is a plastic bathtub made for a certain number of ASICs, computing devices. It's no secret that bitcoin has long been impossible to mine with video cards. A special oily liquid (does not conduct electricity) is poured into the bath for cooling. Coolers were removed from the ASICs and "trickery" in the form of special microcircuits were installed. The heat from their work is transferred to the liquid and then through the heat exchanger is transferred to the water in the heating system.

We shift the cost of electricity for the operation of the equipment to the cost of heating the house. And asiks make a net profit by mining bitcoin, if their capacities are capable of doing this.

When studying the examples, I came across reviews of the owners of such mining farms. An example of their economy. Someone bought in the summer of 2020. ASIC Bitmain Antminer L3 (obsolete equipment), which as of October 2020 mined bitcoin in the amount of electricity costs. Such used equipment was worth then RUB 6,000 / pcs. But then the bitcoin rate was 10 thousand $ / bitcoin. Thus, until November 2020. home heating costs were zero (no profit). But today the bitcoin rate is almost 60 thousand $ / bitcoin. Thus, today the profitability of a mining farm is 500%.

Yes, the immersion cooling system has a decent price tag. In 2018. they cost up 200 thous. rub. for 12 ASICs. You can see about one of the immersion cooling systems (or home heating system) in this video:

There are many such examples in youtube. The advantage of such a cooling system for ASICs is noiselessness. Can be safely installed in the house. There is no dust circulation in the volume of the room.

Is it possible to enter this topic and not fly over? I will not venture to guess whether the bitcoin rate will continue to grow, whether it will remain so, or everything will collapse. But let's count. Purchase expensive equipment, for example, how Asic Antminer Bitmain S17 it makes no sense. The cost of such an ASIC is from 145 thous. rub. And here Bitmain Antminer S 9i today it is sold at a price of less than 5,000 rubles / piece. Link: https://www.antminer-russia.ru/asic-bitmain-antminer-s9i

It has a fairly high performance (up to 14 TH / s). And power: 1400 watts And in liquid it can be dispersed even higher, up to 2 kW. A house up to 150 m2 will need about 10 kW of thermal power, i.e. five ASICs. This is 25 thousand. rub. Let's round up to 30 thous. rub.

The bath can be ordered according to the drawings from the manufacturers of polypropylene pools. They solder quickly, there is little work in winter. I think in 20 thous. rub. you can meet. Heat exchanger: let it be 30 thous. rub. Oil in the system: 200 rubles / liter You need up to 50 liters. Strapping and automation - more 20 thous. rub. Total roughly: 110 thous. rub.

We calculate the cost per month for electricity, it turns out: 2 kW * 5 pcs. * 24 hours * 30 days * 5 rubles / kW * h = 36,000 rubles. (tariff in the Moscow region). In our region, electricity is 2.75 rubles / kW * h. Those. expenses: 19800 RUB Obviously, we don't need all the heat 24 hours a day. And some will have to be taken outside.

With the bitcoin rate, the mining farm, taking into account these costs, will also work 100-180 thous. RUB / month It will pay off in a month. But I repeat - this is at the current rate of $ 60 thousand / bitcoin. But I can be wrong and the computing power of the Bitmain Antminer S 9i is no longer enough for profitable mining. It is necessary to find out. But then you will simply heat the house for free. Although, on aliexpress, even Antminer L3 costs from $ 30 thousand. rub. This means that the equipment is applicable for mining.

A separate issue is setting up equipment and withdrawing funds. This information is beyond the scope of this article.

If the course continues and it will be possible to mine further, then it makes sense to do this in the summer. To do this, you can cool the bath through this fan heater installed outside:

Power dissipation - up to 40 kW. It's still about 30 thous. rub. But in the summer heat, its heat dissipation power can drop to 5 kW. The best cooling method is to pump water out of a well or well and drain it back. Or heat the pool water.

How long will such a high bitcoin rate last - no one knows. Know those who, with only one statement, affect stock prices. But now the equipment can be recouped in one month. And then, if the bitcoin rate collapses, then either the heating of the house will be free for you, or you will cover most of the costs for it.
