USING AT HOME MINING FOR HEAT REDUCED NATURAL GAS USE BY 75% AND REDUCED EFFECTIVE ELECTRICAL RESIDENTIAL RATE TO ONLY $0.062/kWh
This is based on use of heat from 1 S19 pro, 2 T19s and 3 S9s to heat our entire home, basement & garage. Follow along 👇👇 for details.
My prior thread (see 👇👇) on cost savings using at home mining to heat our home was incomplete as not all of the miners were fully online until mid Dec 2021, so I was eagerly awaiting our Jan 2022 natural gas bill.
This time I compared data from Jan 2022 with data from Jan 2018, 2019,2020 and 2021:
For each year I looked at the total number of "therms" we used, the total $$ for those therms, the cost per unit in terms of $$/therm and year-over-year price change. As you can see, our natural gas rates have increased 51.3% in the past 2 years.
I then compared the average Jan therms from 2018-2021 (266 therms avg) with therms in Jan 2022 (only 67 therms), which translates into an "overall" reduction from average Jan nat gas use of 75%. This resulted in a total savings of $295.25 in Jan 2022 versus a typical January.
I then looked at average "base usage" of nat gas (i.e., typical monthly use for hot water & cooking) which I estimated based on data from Aug-Sept and set this value at 45 therms. Based on this, our Jan 2022 use "above base usage" was only 22 therms (i.e., 67-45 = 22).
When looking at average Jan 2018-2021 above base usage (220.75 therms) versus Jan 2022 above base usage (22 therms), the % reduction was even more impressive at 90%!
My cohort of 6 miners (some new, some old) consume 9,468 kWh of electricity per month. Our residential rate is $0.093/kWh. However, if the savings off our Jan nat gas bill is applied to our Jan 2022 electrical bill, our effective electrical rate is $0.062/kWh.
Obviously, we'll not be heating the house for the entire year, so this savings will not apply for all months. However, when winter savings is amortized over the entire year, I would hope to reduce my effective rate to ~$0.08/kWh. I'll follow-up in Jan 2023 with real data.
And for all this Jan 2022 electricity we mined a total of:
At present fiat exchange rate (about $37,500 at time of tweet), this is about $2,095. Future values of BTC are anyone's guess, but ask yourself what you think that might be worth in a few years.
What one mining pleb did to keep cool during the warmer months after heating his entire home during the Winter using only ASIC miners. Follow the 🧵 for details👇🏼
For the past several months although I’ve been keeping the family nice and toasty and saving on our natural gas bills (see 🧵 👇🏼) I’ve been anxious about how to deal with the heat from my ASIC miners during warmer months.
The only viable option in our home was to build a new enclosure in our attic and ventilate it outside. As our home is a brick home, this first required a defilement of our exterior wall. Though I’m handy and a do-it-yourselfer I hired this job out:
Below are annual graphs on our power bills from 2019-2022, with the most recent month (March) at far right in each graph. Y-axis is # of therms. Note the massive reduction in therms during Jan-Mar 2022 (at home mining started in late Nov 2021).
I wanted to organize and share my thoughts about how to design and build soundproof enclosures for at home #BTC mining so anyone interested could do the same. The thread below👇🏼👇🏼 is a complication of knowledge that I’ve gained building 3 different enclosures…
1ST - MAKE A COMPREHENSIVE LIST OF YOUR NEEDS:
- Heat management
- Sound mitigation
- Mobility
- Ventilation (passive vs. active)
- Power and ethernet cord access
- Air filtration
- Factors unique to your situation?
Let’s look at each a little more deeply…
HEAT MANAGEMENT:
Winter - If possible plan to use the heat in your home or workspace to reduce your normal heating bill (see thread 👇🏼👇🏼).
Warmer months - You must plan to ventilate heated air outside.
Just like the prior build for my office heater👇👇, this build started with replacement of the fan in the APW3++ PSU which makes the PSU much, much more quiet.
